Chain couplings

The  Chain coupling is composed of a duplex roller chain and a pair of coupling sprockets. The function of connection and detachment is done by the joint of chain. It has the characteristic of compact and CZPT ful, excellent durability, safe and smart, simple installation and easy alignment. The Xihu (West CZPT ) Dis.hua Chain coupling is suitable for a wide range of coupling applications.

Roller chain( Coupling Chains)

Though Hans 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.Coupling chains)Coupling chains

Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical CZPT  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 CZPT transmission.

^{Construction of the chain
Two different sizes of roller chain, showing construction.
There are two types of links alternating in the bush roller chain. The first type is inner links, having two inner plates held together by two sleeves or bushings upon which rotate two rollers. Inner links alternate with the CZPT type, the outer links, consisting of two 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 one 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 CZPT 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 CZPT as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.
