Roller chain for coupling

Definition of roller chain for coupling:

Coupling roller chain is a type of chain used to transmit mechanical power. It is a type of chain drive. It is widely used in household, industrial and agricultural machinery, including conveyors, plotters, printing machines, automobiles, motorcycles, And bicycles.It is linked by a series of short cylindrical rollers and is driven by a gear called a sprocket.This is a simple power transmission device.

The structure of the roller chain for the coupling:

The roller chain for coupling is composed of rollers, sleeves, pins, inner chain plates and outer chain plates.There is an interference fit between the inner chain plate and the sleeve, the outer chain plate and the pin shaft; there is a clearance fit between the pin shaft and the sleeve, and the sleeve and the roller.When the inner and outer chain plates are relatively flexed, the sleeve can rotate freely around the pin shaft.

The roller chain for the coupling has a simple structure (composed of four housings), convenient assembly and disassembly, no need to move the connected two shafts during disassembly, compact size, light weight, compensation capability, low requirements for installation accuracy, and work , Longer life, lower cost and other advantages.It can be used in the shaft transmission of textile, agricultural machinery, lifting and transportation, engineering, mining, light industry, chemical industry and other machinery. It is suitable for high temperature, humidity and dusty working conditions. It is not suitable for high speed, severe impact load and transmission of axial force. The chain coupling should work under the condition of good lubrication and protective cover. 

The point of using roller chains for couplings: Chain couplings use a common chain that meshes with two parallel sprockets with the same number of teeth. The main difference between chain couplings of different structure types is the use of different chains. Common ones are Double-row roller chain couplings, single-row roller chain couplings, toothed chain couplings, nylon chain couplings, etc.The performance of the double-row roller chain coupling is better than that of other structural couplings. It is widely used (KC series sprocket coupling), and my country has also formulated it as a standard (GB6069-86).
