Sprockets belong to the category of mechanical transmission components

 sprocket is a component in a chain transmission that engages with a chain to transmit motion and power. 

The sprocket has teeth, which transmits movement and power through the meshing of the chain with the sprocket Gear teeth. 

The tightness of the sprocket should be appropriate. If it is too tight, it will increase power consumption and the bearings will easily wear; if it is too loose, the sprocket will easily jump and be off-chain. 

The tightness of the sprocket is: lifted from the middle of the sprocket or pressed, which is about 2%-3% of the center distance between the two sprockets. Sprockets are widely used in mechanical transmission in chemical industry, textile machinery, food processing, instrumentation, petroleum and other industries. Each part of the sprocket has many different characteristics, including the number of teeth, pitch diameter, tooth pitch, etc.

There are many types of sprockets, which can be classified according to material, model size and function. For example, double-layer sprockets, segmented rim sprockets, quick-disassembly (QD) sprockets, idlers, etc. Different types of sprockets are suitable for different occasions and needs
