Roller chain is a type of chain used for transmitting mechanical power, widely used in household, industrial, and agricultural machinery, including conveyors, drawing machines, printing machines, automobiles, motorcycles, and bicycles. It is connected by a series of short cylindrical rollers and driven by a gear called a sprocket, making it a simple, reliable, and efficient power transmission device. Roller chains are divided into single row and multi row types, suitable for low-power transmission. Its basic parameters include the chain link distance ppp, which is equal to the roller chain number multiplied by 25.4/16 (mm). There are two suffixes in the chain number, A and B, which represent two series and complement each other. The roller chain consists of an inner chain plate, an outer chain plate, a pin shaft, a sleeve, and rollers. The inner and outer chain plates have an interference fit with the sleeve, and the outer chain plate has an interference fit with the pin shaft; The roller and sleeve, as well as the sleeve and pin shaft, have a clearance fit. This design allows for relative bending between the inner and outer links, allowing the sleeve to rotate freely around the pin axis. The rollers are fitted onto the sleeve to reduce wear between the chain and sprocket.
In terms of specific applications, such as the scraper conveyor chains provided by Xiangyun Environmental Protection, these chains can be customized according to customer needs, with optional materials, strong tensile strength, and long service life. In addition, the double pitch roller conveyor chain provided by Shenzhen Fusite Automation Equipment Co., Ltd. is suitable for coating chains, automatic line chains, spraying assembly line chains, etc. The material is carbon steel and is suitable for industrial use. In addition, there are also stainless steel roller chains, such as the stainless steel double pitch chain provided by Tengbo Mesh Chain Factory in Ningjin County, which is suitable for high-temperature industrial machinery transmission and has good high-temperature resistance performance.
The choice of roller chain depends on specific application requirements, including load-bearing capacity, working environment, and whether silent operation is required. For example, in situations where silent operation is required, specially designed roller chains or additional noise reduction measures may be chosen. In addition, depending on the specific working conditions, roller chains may require special treatments such as coating or special lubrication to adapt to specific chemical environments or temperature conditions. When choosing a roller chain, one should also consider its maintenance and upkeep needs to ensure long-term stable operation and extend its service life
