Sprocket is a wheel with cog-type buckle sprocket, used to mesh with a block with an accurate pitch on a link or cable, a solid or spoked gear that meshes with a (roller) chain to transmit motion . Application of sprocket: It is widely used in mechanical transmission in chemical, textile machinery, food processing, instrumentation, petroleum and other industries. The role of the sprocket is equivalent to the timing belt, and it is an important part of the engine's air distribution system. It is connected with the crankshaft and matched with a certain transmission ratio to ensure the accuracy of the intake and exhaust time.

Sprockets are of various designs, a maximum of efficiency being claimed for each by its originator. Sprockets typically do not have a flange. Some sprockets used with timing belts have flanges to keep the timing belt centered. Sprockets and chains are also used for power transmission from one shaft to another where slippage is not admissible, sprocket chains being used instead of belts or ropes and sprocket-wheels instead of pulleys. They can be run at high speed and some forms of chain are so constructed as to be noiseless even at high speed.
