ROLLER CHAIN

Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.

CONSTRUCTION OF THE CHAIN

Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CHINAMFG which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.

The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.

LUBRICATION

Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]

There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.

Many oil-based lubricants attract dirt and other particles, eventually forming an CHINAMFG paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.

VARIANTS DESIGN

Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.

Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.

Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.

USE

An example of 2 ‘ghost’ sprockets tensioning a triplex roller chain system
Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CHINAMFG the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CHINAMFG flight, a system known as Thrust vectoring.

WEAR

 

The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).

With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.

The lengthening due to wear of a chain is calculated by the following formula:

M = the length of a number of links measured

S = the number of links measured

P = Pitch

In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.

CHAIN STRENGTH

The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.

The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.

CHAIN STHangZhouRDS

Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):

Pitch (inches) Pitch expressed

12 48 40 516
58 58 50 38
34 68 60 12
1 88 80 58

Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
 A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.

Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.

Roller chains made using ISO standard are sometimes called as isochains.

What are the noise and vibration characteristics of engineering chains?

Engineering chains, like other types of roller chains, can produce noise and vibrations during their operation. The noise and vibration characteristics of engineering chains depend on several factors:

  • Lubrication: Proper lubrication of the chain can help reduce friction between the chain’s components, leading to smoother operation and lower noise levels.
  • Chain Condition: A well-maintained chain with proper tension and minimal wear is likely to produce less noise and vibration compared to a worn or damaged chain.
  • Alignment: Proper alignment of the sprockets and the chain is essential to minimize lateral forces, which can contribute to increased noise and vibration.
  • Load and Speed: Heavier loads and higher speeds can increase the dynamic forces within the chain, leading to more pronounced noise and vibration.
  • Environmental Factors: External factors, such as temperature, humidity, and contaminants, can influence the chain’s noise and vibration characteristics.

Chain noise and vibration can be managed through various measures:

  • Chain Design: Some chains are designed with noise reduction features, such as special profile plates or noise-dampening materials.
  • Lubrication: Using high-quality and appropriate lubricants can help reduce friction and noise.
  • Tensioning: Properly tensioned chains experience less vibration and are less likely to produce noise.
  • Maintenance: Regular inspection and maintenance can identify and address any issues that may contribute to increased noise and vibration.
  • Isolation: In some applications, adding vibration isolators or dampeners can help reduce the transmission of noise and vibrations to surrounding structures.

It’s important to consider the specific requirements of the application and consult with chain manufacturers or experts to select the most suitable engineering chain and implement noise and vibration mitigation strategies when necessary.

What are the benefits of using an engineering chain over other power transmission methods?

Engineering chains offer several advantages over other power transmission methods, making them a preferred choice in various industrial applications:

  • High Strength: Engineering chains are designed to handle heavy loads and high torque, making them suitable for demanding applications that require robust and reliable power transmission.
  • Wide Range of Sizes: These chains are available in a wide range of sizes and configurations, allowing for flexibility in design and accommodating various application requirements.
  • Durable and Long-Lasting: When properly maintained, engineering chains have a long service life, reducing the need for frequent replacements and minimizing downtime in industrial operations.
  • Adaptable to Harsh Environments: Engineering chains are capable of operating in harsh conditions, including dusty, dirty, or corrosive environments, without compromising their performance.
  • Shock Load Resistance: The design of engineering chains allows them to handle sudden impact forces and shock loads, which can occur in certain industrial processes.
  • Cost-Effective: Engineering chains often provide a cost-effective solution for power transmission compared to other methods, especially in high-load applications.
  • Simple Installation: With proper alignment and tensioning, engineering chains are relatively easy to install, reducing installation time and labor costs.
  • Bi-Directional Power Transmission: Engineering chains can transmit power in both forward and reverse directions, making them suitable for applications requiring bidirectional motion.
  • Low Maintenance: Regular maintenance, such as lubrication and inspection, can keep engineering chains in good working condition, reducing overall maintenance costs.
  • Reduction of Noise and Vibration: When adequately lubricated and aligned, engineering chains can operate quietly and with minimal vibration, contributing to a more comfortable and safer working environment.

Despite their many advantages, it’s essential to consider the specific requirements of each application before selecting an engineering chain. Factors such as load capacity, speed, environmental conditions, and space constraints should be taken into account to ensure the chain’s optimal performance and longevity.

In summary, engineering chains are a versatile and reliable power transmission method, offering a range of benefits that make them well-suited for use in various industrial settings.

What materials are engineering chains typically made of?

Engineering chains are commonly made from a variety of durable and high-strength materials to ensure their performance and longevity in demanding industrial applications. The choice of material depends on factors such as the application’s requirements, environmental conditions, and the specific type of engineering chain. Some of the typical materials used for engineering chains include:

1. Carbon Steel: Carbon steel is a popular choice for engineering chains due to its excellent strength and affordability. It is suitable for many standard industrial applications where moderate strength and resistance to wear are required.

2. Alloy Steel: Alloy steel offers higher strength and better resistance to wear and fatigue compared to carbon steel. It is commonly used in heavy-duty and high-stress applications, such as mining equipment and construction machinery.

3. Stainless Steel: Stainless steel is chosen for its corrosion resistance properties, making it ideal for applications where the chain may be exposed to moisture, chemicals, or harsh environments. It is commonly used in food processing, pharmaceuticals, and outdoor applications.

4. Nickel-Plated Steel: Nickel-plated steel chains provide enhanced corrosion resistance while retaining the strength of carbon or alloy steel. They are often used in applications where both strength and corrosion resistance are important.

5. Plastic: In some cases, engineering chains may be constructed entirely from plastic or have plastic components. Plastic chains are commonly used in industries requiring low noise, lightweight, and corrosion resistance, such as the food and beverage industry and packaging applications.

6. Other Specialty Materials: Depending on the specific requirements of an application, engineering chains may also be made from other specialty materials like bronze, zinc-plated steel, or coated chains to meet particular needs.

The choice of material is crucial in determining the performance, longevity, and suitability of the engineering chain for a specific application. Manufacturers provide information on the material composition of their chains, allowing users to select the most appropriate material based on the intended use and operating conditions.

Though CHINAMFG Renold is credited with inventing the roller chain in 1880, sketches by Leonardo da Vinci in the 16th century show a chain with a roller bearing.

Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.

Use

An example of 2 ‘ghost’ sprockets tensioning a triplex roller chain system
Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CHINAMFG the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CHINAMFG flight, a system known as Thrust vectoring.
 

Wear

The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).

With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.

The lengthening due to wear of a chain is calculated by the following formula:

{\displaystyle \%=((M-(S*P))/(S*P))*100}

 

M = the length of a number of links measured

S = the number of links measured

P = Pitch

In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.

Chain strength

The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.

The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.

Chain standards

Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

ASME/ANSI B29.1-2011 Roller Chain Standard SizesSizePitchMaximum Roller DiameterMinimum Ultimate Tensile StrengthMeasuring Load25.

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):

Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
 A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.

Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.

Roller chains made using ISO standard are sometimes called as isochains.

Here’s how engineering chains handle misalignment:

  1. Flexible Construction: Engineering chains are constructed with flexible components such as pins, rollers, and bushings. This design allows the chain to adapt to minor misalignments without putting excessive stress on the chain or sprockets.
  2. Articulating Joints: The articulating joints in the chain allow it to articulate smoothly around the sprockets, accommodating minor misalignment during the rotation. This helps reduce wear on the chain and sprockets.
  3. Tolerance for Misalignment: Manufacturers provide specifications for the allowable misalignment between sprockets. Engineering chains are designed to handle a certain level of misalignment within these tolerances without significantly affecting their performance.
  4. Proper Installation: Correct installation of the engineering chain is crucial to minimizing misalignment issues. Ensuring proper tension, alignment, and center-to-center distance between sprockets can help reduce misalignment and prolong chain life.
  5. Regular Maintenance: Regular maintenance, including chain inspection and lubrication, can help identify and address misalignment issues early on. Promptly correcting misalignment can prevent further damage and ensure efficient chain operation.
  6. Alignment Devices: In some cases, alignment devices or tools may be used during installation to ensure accurate alignment between the sprockets. These devices can help improve chain performance and reduce wear caused by misalignment.

It is essential to follow the manufacturer’s guidelines for chain installation, maintenance, and alignment to optimize the performance and service life of engineering chains. Addressing misalignment issues promptly and keeping the chain in proper working condition will contribute to the overall reliability and efficiency of the machinery or equipment in which the chain is used.

How do engineering chains handle reverse motion or anti-reverse requirements?

Engineering chains are designed to handle reverse motion or anti-reverse requirements in certain applications. This capability is essential in situations where the load or the machinery needs to move back and forth. Here’s how engineering chains achieve this:

1. Tooth Shape: Many engineering chains, such as roller chains or silent chains, feature a specific tooth shape on the sprockets. The tooth profile is designed to engage the chain rollers or links in one direction, allowing smooth motion, while preventing engagement in the reverse direction, effectively acting as an anti-reverse mechanism.

2. One-Way Clutches: Some engineering chain applications may incorporate one-way clutches or overrunning clutches. These devices allow the chain and sprockets to engage and transmit power in one direction, while freewheeling or disengaging in the opposite direction, preventing reverse motion.

3. Ratcheting Mechanisms: In certain engineering chain systems, ratcheting mechanisms are employed to allow forward motion and prevent backward movement. These mechanisms consist of pawls and teeth that engage in one direction and disengage in the reverse direction, effectively providing an anti-reverse function.

4. Backstop Clutches: Backstop clutches are used to prevent reverse motion in specific engineering chain applications. These clutches allow the chain to engage and transmit power in one direction, while locking and preventing motion in the reverse direction.

5. Tensioning Devices: Proper tensioning of the engineering chain can also play a role in preventing reverse motion. Adequate tension helps keep the chain engaged with the sprockets in the desired direction, reducing the risk of slipping or backdriving.

6. Design and Orientation: Engineers can design the system in a way that naturally discourages reverse motion. For example, the layout of the chain path and the arrangement of sprockets can make it less likely for the chain to move in the opposite direction.

By using these methods and incorporating suitable components, engineering chains can effectively handle reverse motion or anti-reverse requirements, ensuring the safe and reliable operation of machinery in applications where back-and-forth motion is necessary.

engineering chain

ROLLER CHAIN

Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.

CONSTRUCTION OF THE CHAIN

Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CHINAMFG which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.

The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.

LUBRICATION

Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]

There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.

Many oil-based lubricants attract dirt and other particles, eventually forming an CHINAMFG paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.

VARIANTS DESIGN

Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.

Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.

Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.

USE

An example of 2 ‘ghost’ sprockets tensioning a triplex roller chain system
Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CHINAMFG the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CHINAMFG flight, a system known as Thrust vectoring.

WEAR

 

The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).

With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.

The lengthening due to wear of a chain is calculated by the following formula:

M = the length of a number of links measured

S = the number of links measured

P = Pitch

In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.

CHAIN STRENGTH

The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.

The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.

CHAIN STHangZhouRDS

Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):

Pitch (inches) Pitch expressed

Width (inches)
14 28 25 18
38 38 35 316
12 48 41 14
12 48 40 516
58 58 50 38
34 68 60 12
1 88 80 58

Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
 A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.

Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.

Roller chains made using ISO standard are sometimes called as isochains.

What are the noise and vibration characteristics of engineering chains?

Engineering chains, like other types of roller chains, can produce noise and vibrations during their operation. The noise and vibration characteristics of engineering chains depend on several factors:

  • Lubrication: Proper lubrication of the chain can help reduce friction between the chain’s components, leading to smoother operation and lower noise levels.
  • Chain Condition: A well-maintained chain with proper tension and minimal wear is likely to produce less noise and vibration compared to a worn or damaged chain.
  • Alignment: Proper alignment of the sprockets and the chain is essential to minimize lateral forces, which can contribute to increased noise and vibration.
  • Load and Speed: Heavier loads and higher speeds can increase the dynamic forces within the chain, leading to more pronounced noise and vibration.
  • Environmental Factors: External factors, such as temperature, humidity, and contaminants, can influence the chain’s noise and vibration characteristics.

Chain noise and vibration can be managed through various measures:

  • Chain Design: Some chains are designed with noise reduction features, such as special profile plates or noise-dampening materials.
  • Lubrication: Using high-quality and appropriate lubricants can help reduce friction and noise.
  • Tensioning: Properly tensioned chains experience less vibration and are less likely to produce noise.
  • Maintenance: Regular inspection and maintenance can identify and address any issues that may contribute to increased noise and vibration.
  • Isolation: In some applications, adding vibration isolators or dampeners can help reduce the transmission of noise and vibrations to surrounding structures.

It’s important to consider the specific requirements of the application and consult with chain manufacturers or experts to select the most suitable engineering chain and implement noise and vibration mitigation strategies when necessary.

Can engineering chains be used in food processing or packaging industries?

Yes, engineering chains can be used in food processing and packaging industries under certain conditions. However, several considerations must be taken into account to ensure the safe and hygienic use of engineering chains in such applications.

Key factors to consider when using engineering chains in the food industry include:

  • Food-Grade Materials: Engineering chains intended for use in food processing and packaging must be made from food-grade materials that meet industry standards for cleanliness and hygiene. Stainless steel chains are commonly used in these applications due to their corrosion resistance and ease of cleaning.
  • Design and Construction: The chain design should minimize crevices, pockets, or areas that can trap food particles or contaminants. Smooth surfaces and sealed joints are preferred to facilitate thorough cleaning and prevent bacterial growth.
  • Temperature and Chemical Resistance: Engineering chains should be capable of withstanding the temperature ranges and cleaning agents used in food processing facilities without compromising their performance or integrity.
  • Lubrication: If lubrication is required, food-grade lubricants must be used to avoid contamination of the food products or packaging materials.
  • Cleanability: The chain and its components should be easily accessible for cleaning and sanitation procedures. Quick disassembly and reassembly can also be beneficial for efficient cleaning processes.
  • Regulatory Compliance: Compliance with food safety and sanitation regulations is of utmost importance. Engineering chains used in the food industry should meet industry standards and regulations to ensure product safety.

It’s crucial for food processing and packaging companies to work closely with chain suppliers who understand the specific requirements of the industry and offer chains designed and manufactured to meet these standards. Regular maintenance and inspections are essential to detect any signs of wear, damage, or contamination that could compromise the chain’s suitability for food-related applications.

By adhering to these guidelines and best practices, engineering chains can safely and effectively be used in food processing and packaging industries, contributing to the efficient and reliable operation of conveyor systems and other equipment in these critical sectors.

What are the different types of engineering chains available in the market?

Engineering chains come in various types, each designed to meet specific industrial needs and operating conditions. Here are some of the common types of engineering chains available in the market:

  • Roller Chains: Roller chains are the most common type of engineering chain and consist of cylindrical rollers that engage with the sprocket teeth for smooth power transmission. They are widely used in industries like manufacturing, agriculture, and automotive.
  • Drag Chains: Drag chains, also known as conveyor chains or slat chains, have flat, interlocking plates connected together. They are used in conveyor systems for material handling applications, especially in heavy-duty and abrasive environments.
  • Hollow Pin Chains: Hollow pin chains feature hollow pins that allow for the insertion of cross rods or attachments, making them versatile for handling irregularly shaped loads or for use as a conveyor in specific industries.
  • Double Pitch Chains: Double pitch chains have larger pitch distances between the links, resulting in lighter weight and lower cost. They are commonly used in low-speed and light-load applications.
  • Leaf Chains: Leaf chains, also known as forklift chains, are used in lifting applications, such as forklift trucks and other material handling equipment.
  • Side Bow Chains: Side bow chains have links with a curved or bent shape, allowing them to flex and bend laterally, making them suitable for curved or circular conveyor applications.
  • Apron Chains: Apron chains are used in apron conveyors, typically found in the mining and cement industries, for transporting heavy and abrasive materials.
  • Specialty Chains: There are various specialty chains available for specific industries and applications, such as escalator chains, agricultural chains, bottle conveyor chains, and more.

Each type of engineering chain has its own unique design and features to cater to specific requirements. The choice of chain type depends on factors like load capacity, speed, environmental conditions, and the application’s needs. It’s essential to select the appropriate chain type and ensure proper maintenance to achieve optimal performance and longevity in industrial operations.
