Industrial roller chain drive is utilized for the transmission of machine-driven power to bicycles, conveyors, motorcycles, and printing presses. Moreover, industrial roller chain drive finds applications in food processing equipment, material handling instruments, and manufacturing devices. In addition, these products are easy to maintain and cost-efficient. Furthermore, in the manufacturing sector, the roller chain plays a major role in proficient energy transmission between various machine components, thereby ensuring less power loss at the time of gear shifting.
Apart from this, the industrial roller chain drives are utilized in heavy-duty and domestic equipment in various industries and agricultural instruments owing to their outstanding power-to-weight ratio during transmission of torque over a larger distance. Moreover, industrial roller chain drives help in enhancing the output along with reducing friction between machine components, thereby leading to the minimization of wear & tear. This also results in cost savings on repairs of equipment parts in the manufacturing sector.
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.
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.
Many oil-based lubricants attract dirt and other particles, eventually forming an abrasive paste that will compound wear on chains. This problem can be reduced by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.
