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[1] means of power transmission.
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.
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.

How does a bush chain handle reverse rotations and backdrives?
A bush chain is designed to handle reverse rotations and backdrives effectively. Here’s how it works:
1. Non-Slip Design: Bush chains are typically constructed with interlocking link plates and precision-fitted bushings. This design ensures that the chain maintains a positive engagement with the sprockets, preventing slippage or disengagement during reverse rotations or backdrives.
2. Tooth Profile: The sprockets used with bush chains are designed with a specific tooth profile that helps in maintaining proper chain engagement even during reverse rotations. The tooth shape ensures a smooth transition of the chain from one tooth to another, minimizing the risk of skipping or jumping off the sprocket.
3. Backstop Mechanisms: In some applications where backdrives or reverse rotations are more common, additional backstop mechanisms may be employed. These mechanisms prevent the chain from moving in the undesired direction by utilizing devices such as one-way clutches or backstop sprockets.
4. Proper Chain Tension: Maintaining proper chain tension is crucial for reliable operation in reverse rotations and backdrives. Adequate tension ensures that the chain remains engaged with the sprockets and minimizes the possibility of slippage.
Overall, bush chains are designed to handle reverse rotations and backdrives without compromising their performance and reliability. However, it is important to consider the specific application requirements and consult with chain manufacturers or experts to ensure the selection of the appropriate bush chain design and components for the desired operating conditions.
How does a bush chain contribute to overall system efficiency?
A bush chain contributes to overall system efficiency in several ways:
1. Power transmission: Bush chains are designed to efficiently transmit power from the driving source to the driven machinery or equipment. They have high tensile strength and can effectively transfer rotational motion, allowing for the efficient transfer of power from the motor or engine to the intended application.
2. Load-bearing capacity: Bush chains are capable of handling heavy loads and are designed to withstand the stresses associated with transmitting power in industrial applications. By efficiently transferring the load, they minimize power losses and reduce the need for additional components or systems.
3. Smooth and reliable operation: Bush chains are constructed with precision-engineered components that work together to provide smooth and reliable operation.
