How do roller chains handle side loads?

Roller chains are designed to primarily handle axial (or in-line) loads, which are forces applied along the axis of the chain. However, they do have some capability to handle limited side loads. Here’s a detailed answer to the question:

1. Roller Design: The rollers in a roller chain are cylindrical in shape and rotate freely between the inner and outer plates. This design allows the chain to accommodate limited side loads by allowing the rollers to roll and adjust their position within the chain.

2. Bearing Surfaces: Roller chains have bearing surfaces between the pins and the bushings or rollers. These bearing surfaces help distribute the load and reduce friction, allowing the chain to handle some degree of side loads.

3. Tolerance for Misalignment: Roller chains have some tolerance for misalignment between the sprockets, which can help compensate for minor side loads. However, excessive misalignment can lead to increased wear and decreased chain life.

4. Limitations: It’s important to note that roller chains are primarily designed for transmitting power and handling axial loads. While they can tolerate some side loads, their ability to handle significant side loads is limited. Excessive side loads can cause increased wear, premature chain failure, and reduced overall performance.

To ensure the longevity and reliable performance of a roller chain, it is essential to minimize side loads as much as possible. Proper alignment of the sprockets, appropriate tensioning of the chain, and avoiding excessive side loads are important considerations when using roller chains in an application.

What are the limitations of using roller chains in certain applications?

Roller chains are versatile and widely used in various applications, but they do have some limitations to consider. Here’s a detailed answer to the question:

1. Speed Limitations: Roller chains have a practical speed limit due to factors such as chain length, centrifugal forces, and roller-to-sprocket engagement. At high speeds, the centrifugal forces can cause excessive chain vibration and increase wear, potentially leading to chain failure. In such cases, alternative power transmission systems like gears or belts may be more suitable.

2. Precision Requirements: Roller chains require proper alignment and tensioning for efficient operation. In applications that demand high precision, such as precision machinery or robotics, the inherent flexibility and slight elongation of roller chains may not meet the desired accuracy requirements. In such cases, alternative systems like timing belts or direct drive solutions may be preferred.

3. Environmental Limitations: Roller chains may not be suitable for certain environments with extreme temperatures, corrosive substances, or high levels of contamination. Harsh conditions can accelerate chain wear, reduce lubrication effectiveness, or cause corrosion. In these situations, specialized chains with appropriate coatings or alternative power transmission systems may be necessary.

4. Noise and Vibration: Roller chains can generate noise and vibrations during operation, particularly when not properly tensioned or maintained. In applications where noise or vibration is a concern, such as in noise-sensitive environments or precision machinery, additional measures like chain tensioners, vibration dampening, or alternative drive systems may be required.

5. Size and Space Constraints: Roller chains have a certain physical size and require appropriate clearance for installation. In applications with limited space or tight packaging requirements, alternative power transmission systems like compact belts or direct drives might be more suitable.

It’s important to carefully evaluate the specific requirements and constraints of each application when considering the use of roller chains. Alternative power transmission systems may be more suitable in certain cases, and consulting with experts or manufacturers can help determine the best solution for the intended application.

What is a roller chain and how does it work?

A roller chain is a type of transmission chain that is commonly used in various mechanical systems to transmit power and motion between rotating shafts. It consists of a series of interconnected links, including inner plates, outer plates, rollers, and pins. Here’s a detailed answer to the question:

A roller chain operates based on the principle of contact and rolling motion. The basic components of a roller chain include:

  • Inner Plates: These are flat metal plates with holes through which the pins pass.
  • Outer Plates: These are similar to inner plates and are connected to the inner plates through pins.
  • Rollers: The rollers are cylindrical components that are positioned between the inner and outer plates. They have a slightly larger diameter than the pins, allowing them to freely rotate.
  • Pins: The pins hold the inner and outer plates together and provide a pivot point for the rollers. They pass through the holes in the inner and outer plates and secure them in place.

When the roller chain is installed in a system, it wraps around a pair of sprockets. The sprockets have teeth that mesh with the rollers of the chain. As one sprocket rotates, it engages with the rollers and pulls the chain along, causing the other sprocket to rotate as well.

The working principle of a roller chain involves the following steps:

  1. Engagement: The chain is positioned around the sprockets, and the rollers engage with the teeth of the sprockets.
  2. Tension: The tension in the chain is created by the movement of the sprockets, which causes the chain to wrap tightly around them.
  3. Rolling Motion: As the sprockets rotate, they impart a rolling motion to the rollers. The rollers, in turn, rotate freely on the pins, allowing the chain to move smoothly along the sprockets.
  4. Power Transmission: The rotational motion of one sprocket is transferred to the other sprocket through the chain. This enables the transmission of power and motion between the two shafts connected to the sprockets.

Roller chains are widely used in various applications, including machinery, automobiles, motorcycles, bicycles, conveyors, and more. They offer high efficiency, reliability, and the ability to transmit substantial amounts of power. Regular maintenance, including lubrication and periodic inspection, is essential to ensure the proper functioning and longevity of a roller chain.

How do roller chains handle static loads?

Roller chains are primarily designed for transmitting power and handling dynamic loads, which involve motion and varying forces. However, roller chains can also handle static loads to some extent. Here’s a detailed answer to the question:

1. Load Distribution: When a roller chain is subjected to static loads, the weight or force is evenly distributed across multiple rollers and pins. This helps to distribute the load more effectively and reduces stress concentrations on individual components. The load is transferred from one roller to another through the pins, ensuring a more balanced distribution.

2. Stiffness: Roller chains possess a certain degree of stiffness that enables them to resist static loads. The rigid construction of the chain, including the link plates and pins, helps maintain the integrity of the chain under static conditions. This stiffness allows the chain to support the applied load without excessive elongation or deformation.

3. Lubrication: Proper lubrication is essential for roller chains to handle static loads effectively. Lubrication helps reduce friction and wear, which can occur even under static conditions due to the weight of the load. Adequate lubrication ensures smooth movement of the chain and minimizes the risk of surface damage or increased friction during load-bearing.

4. Chain Preload: In some cases, applying a pre-load or initial tension to the roller chain can help improve its ability to handle static loads. The pre-load helps to eliminate any slack or looseness in the chain, enhancing its rigidity and reducing the potential for excessive elongation or misalignment when subjected to static forces.

While roller chains can handle static loads, it’s important to note that they are primarily designed for dynamic applications involving motion. Excessive static loads or prolonged exposure to static conditions may lead to increased wear, elongation, or deformation of the chain. In scenarios where the majority of the load is static, alternative power transmission systems or load-bearing mechanisms may be more suitable.

roller chain

What is the expected lifespan of a roller chain?

The expected lifespan of a roller chain can vary depending on several factors, including the quality of the chain, the operating conditions, and the level of maintenance. Here’s a detailed answer to the question:

The lifespan of a roller chain is primarily influenced by the following factors:

1. Chain Quality: High-quality roller chains made from durable materials and manufactured to precise specifications tend to have a longer lifespan compared to lower-quality chains. Chains from reputable manufacturers often undergo rigorous testing and quality control processes to ensure their performance and durability.

2. Operating Conditions: The operating environment greatly affects the lifespan of a roller chain. Factors such as temperature, humidity, contamination, shock loads, and vibration can impact the chain’s wear and fatigue resistance. Chains operating in harsh conditions may require more frequent maintenance and replacement.

3. Lubrication and Maintenance: Proper lubrication is crucial for maintaining the lifespan of a roller chain. Regular lubrication helps reduce friction, wear, and corrosion, thereby extending the chain’s life. Additionally, regular inspection and maintenance, including tension adjustment, sprocket alignment, and cleaning, can help identify and address issues that could shorten the chain’s lifespan.

4. Load and Speed: The load and speed at which the roller chain operates also play a role in determining its lifespan. Chains operating under heavy loads or high speeds may experience increased wear and fatigue, shortening their lifespan. Choosing a chain with the appropriate strength and size for the application is important to ensure optimal performance and longevity.

Generally, a well-maintained roller chain can last for thousands of hours of operation. However, it is essential to monitor the chain’s condition regularly and replace it when signs of wear, elongation, or damage become apparent. Following the manufacturer’s recommendations for maintenance and replacement intervals is crucial for maximizing the lifespan of the roller chain.

How do roller chains handle lateral loads?

Roller chains are primarily designed to handle axial loads, which are loads acting in the direction of the chain’s axis. However, roller chains can also tolerate a certain degree of lateral loads, which are loads acting perpendicular to the chain’s axis. Here’s a detailed answer to the question:

1. Sprocket Alignment: Proper sprocket alignment is crucial for roller chains to effectively handle lateral loads. The sprockets must be aligned in a parallel and concentric manner to ensure that the chain tracks properly and experiences minimal lateral force. Misaligned sprockets can cause the chain to derail or experience excessive wear due to uneven loading.

2. Tolerance for Lateral Misalignment: Roller chains have some tolerance for lateral misalignment between the sprockets. This means that the chain can tolerate a slight deviation from a perfectly straight line between the sprockets. The chain’s side plates and rollers are designed to provide some flexibility, allowing the chain to adjust to minor lateral forces without significant problems.

3. Guide Rails or Flanges: In applications where lateral loads are more significant, guide rails or flanges can be employed to help keep the roller chain aligned and prevent excessive lateral movement. These additional components act as guides and help control the chain’s lateral displacement, ensuring that it remains on the sprockets and operates smoothly.

4. Chain Tension: Proper chain tension is crucial for handling lateral loads. A well-tensioned chain minimizes slack and reduces the chances of lateral movement. It helps keep the chain engaged with the sprockets and ensures that the load is evenly distributed across the chain’s width.

It’s important to note that roller chains have a primary function of transmitting power and handling axial loads. While they can handle some lateral loads within their design limits, excessive lateral forces can lead to chain derailment, increased wear, and reduced performance. Therefore, it’s essential to design the system properly, consider the anticipated lateral loads, and ensure proper alignment and tension to maintain the chain’s integrity and performance.

What are the signs of roller chain wear and when should it be replaced?

Roller chain wear is a natural occurrence due to the repetitive motion and load-bearing nature of the chain. Recognizing the signs of wear is important to ensure the safe and efficient operation of the chain. Here’s a detailed answer to the question:

1. Elongation: Roller chains can elongate over time due to wear on the pins, bushings, and rollers. To check for elongation, measure the distance between a specific number of links (e.g., 10 or 12) over a known length. If the measured distance exceeds the standard pitch length, it indicates chain elongation and the need for replacement.

2. Chain Slack: Excessive chain slack or sag is another sign of wear. When the chain becomes elongated, it fails to maintain the proper tension, resulting in increased slack. Excessive chain slack can cause poor engagement with sprockets, resulting in skipping or jumping and affecting the overall performance of the chain.

3. Misalignment: As a roller chain wears, it may start to misalign with the sprockets. This misalignment can cause the chain to ride unevenly on the sprocket teeth, leading to accelerated wear on the chain and sprockets. If you notice the chain consistently riding to one side of the sprocket, it may be a sign of wear and misalignment.

4. Chain Noise: Worn roller chains can produce increased noise during operation. Excessive wear on the chain components can cause rattling, clicking, or grinding sounds. Unusual noises should be investigated, as they may indicate significant wear or damage to the chain.

5. Visible Signs of Wear: Inspect the chain visually for signs of wear, such as rust, discoloration, or visible damage to the rollers, pins, or bushings. Excessive wear on these components can affect the chain’s ability to properly engage with the sprockets and transmit power efficiently.

When to replace a roller chain depends on various factors, including the severity of wear, the criticality of the application, and the manufacturer’s recommendations. It is generally recommended to replace a roller chain when it has elongated beyond the allowable limits, exhibits excessive wear, or shows signs of damage that can compromise its performance and safety.

Regular inspection and maintenance of roller chains are essential to identify signs of wear and ensure timely replacement. Replacing the chain at the appropriate time helps prevent unexpected failures, reduces downtime, and maintains the overall efficiency of the machinery or equipment.

How do roller chains handle reverse motion?

Roller chains are capable of handling reverse motion in applications where the direction of movement needs to be reversed. Here’s a detailed answer to the question:

1. Bi-Directional Operation: Roller chains are designed to operate in both forward and reverse directions. The chain links and rollers are constructed to engage with the sprockets in either direction, allowing the chain to smoothly transfer power and motion.

2. Engagement with Sprockets: When the roller chain is in reverse motion, the rollers on the chain engage with the sprocket teeth in the opposite direction compared to forward motion. The engagement between the chain and the sprockets ensures a secure and reliable power transmission, allowing the chain to efficiently transfer motion in reverse.

3. Lubrication and Maintenance: Proper lubrication is essential for the smooth operation of roller chains, including during reverse motion. Adequate lubrication reduces friction and wear, ensuring the chain’s longevity and performance. Regular maintenance, including lubrication and inspection, helps identify any issues that may affect the chain’s ability to handle reverse motion and allows for timely corrective actions.

4. Proper Tensioning: Maintaining proper tension in the roller chain is crucial for its performance in both forward and reverse motion. Adequate tension ensures the chain remains engaged with the sprockets and prevents slippage or disengagement during reverse operation. Proper tensioning can be achieved through tensioning devices or adjustable mounting arrangements.

5. Load Capacity: Roller chains are designed to handle various loads, including reverse motion. However, it’s important to consider the specific application requirements and select a roller chain with the appropriate load capacity and strength to withstand the forces experienced during reverse operation.

6. Alignment and Installation: Proper alignment of the roller chain and the sprockets is essential for reliable performance in both forward and reverse motion. Ensuring correct installation, including proper alignment and tensioning, helps maintain the chain’s engagement with the sprockets and ensures smooth operation in reverse.

It’s worth noting that the specific application requirements, such as speed, load, environmental conditions, and the type of roller chain, should be considered when determining the suitability of roller chains for reverse motion. Consulting the manufacturer’s guidelines and recommendations is important to ensure proper selection, installation, and maintenance of roller chains in applications involving reverse operation.

roller 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 CZPT 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 CZPT 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 CZPT 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 CZPT 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.

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
in eighths

chain number
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.

Can roller chains be used in low-temperature environments?

Yes, roller chains can be used in low-temperature environments, but there are several factors to consider for their proper performance and longevity:

1. Material Selection: Choose roller chains that are specifically designed for low-temperature applications. These chains are typically made from materials that can withstand the cold temperatures without becoming brittle or losing their mechanical properties. Common materials used in low-temperature roller chains include stainless steel, nickel-plated steel, or special alloys.

2. Lubrication: Proper lubrication is essential in low-temperature environments to ensure smooth operation and prevent excessive wear. However, it’s important to consider the type of lubricant used as some lubricants may become less effective or thickened at low temperatures. Select lubricants that are specifically formulated for low-temperature applications to maintain proper chain lubrication and reduce friction.

3. Temperature Ratings: Check the temperature ratings provided by the roller chain manufacturer. Ensure that the roller chain is suitable for the specific low-temperature range of your application. Different roller chains have different temperature limits, and exceeding these limits can lead to decreased performance, increased wear, and potential chain failure.

4. Impact Resistance: Low temperatures can make materials more susceptible to impact damage. It’s important to ensure that the roller chain selected has good impact resistance properties to withstand any sudden shocks or loads that may occur during operation in low-temperature environments.

5. Environmental Factors: Consider the overall environmental conditions of the low-temperature environment. Factors such as moisture, ice, or freezing conditions can affect the performance of roller chains. In such cases, additional protection measures like sealing, covers, or regular maintenance may be necessary to prevent ice formation or moisture ingress.

6. Regular Inspection and Maintenance: Regularly inspect the roller chains for signs of wear, damage, or inadequate lubrication. Monitor their performance and address any issues promptly. In low-temperature environments, extreme cold can exacerbate any existing issues, so proactive maintenance is crucial to ensure the continued reliability of the roller chains.

By considering these factors and selecting roller chains designed for low-temperature applications, you can ensure their proper functioning and durability in low-temperature environments.
