Drive Chain Manufacturers Introduction According to different uses, chains can be divided into three categories: lifting chains, traction chains and drive chains. Lifting chain is mainly used for lifting heavy objects in hoisting machinery, and its working speed v≤0.25m/s; traction chain is mainly used for moving heavy objects in chain conveyors, and its working speed v≤4m/s; transmission chain is used for In general machinery, the movement and power are transmitted, and the working speed is usually v≤15m/s.
There are two types of transmission chains: toothed chains and roller chains. Toothed chain is the use of specific tooth-shaped chain pieces and sprocket meshing to achieve transmission. The toothed chain transmission is stable and the noise is very small, so it is also called silent chain transmission. The allowable working speed of the toothed chain can reach 40m/s, but the manufacturing cost is high and the weight is heavy, so it is mostly used in high-speed or high-motion accuracy requirements.
The chains used for power transmission mainly include sleeve roller chains and toothed chains. Sleeve roller chain is composed of inner chain plate, outer chain plate, sleeve, pin and roller. The outer chain plate is fixed on the pin shaft, and the inner chain plate is fixed on the sleeve. The roller and the sleeve and the sleeve and the pin can rotate relative to each other. Therefore, the meshing between the chain and the sprocket is mainly rolling friction. Sleeve roller chain can be used in single row and multiple rows, and multiple rows can transmit higher power. Sleeve roller chains are lighter in weight, longer life and lower cost than tooth chains. It is widely used in power transmission.
The toothed chain is assembled by using pins to assemble multiple pairs of chain pieces with a working surface with an angle of 60°. The working surface of the chain piece meshes with the sprocket. In order to prevent the chain from falling off the sprocket when working, the chain is equipped with inner guide pieces or outer guide pieces. When engaged, the guide piece fits into the corresponding guide groove on the sprocket. The toothed chain has stable transmission and low noise, so it is also known as silent chain and is often used for high-speed transmission. The tooth profile of the sleeve roller chain and the toothed chain sprocket should ensure that the chain can enter or exit the mesh freely, with little impact when meshing, and good contact when meshing.
