The main function of the transmission sprocket is to transfer the power from the power source (such as a motor, engine, etc.) to another wheel or device through a chain, thereby realizing the operation of the mechanical device. It is usually composed of one or more gears, on which a certain number of teeth are distributed. These teeth are combined with the rollers or plate links of the chain, and the power and torque are transmitted through the meshing between the teeth and the chain. The material of the transmission sprocket is usually selected from high-strength and wear-resistant materials, such as carbon steel, alloy steel, stainless steel, etc. When selecting the material, it is necessary to consider the load, speed and service life requirements of the working environment.
