Motorcycle Chain and Sprocket manufacturers tell you that the service life of the sprocket is short, which is far from meeting the requirements of production practice. According to the use of the sprocket, processing status, and manufacturing technology, some improvement measures are proposed for the sprocket:

(1) Motorcycle Chain and Sprocket manufacturers tell you that the original sprocket design material is generally 40Cr. This method basically cannot improve the wear resistance of the sprocket due to the limited quenching hardness of the teeth.
Motorcycle Chain and Sprocket manufacturers tell you that it is recommended to change the sprocket material to 20CrMnTi, carburizing and quenching, the chain nest hardness can reach above HRC60, and its wear resistance is more than 2.5 times that of 40Cr material. This can greatly improve the service life of the sprocket, reduce the frequency of machine repairs, improve productivity and reduce production costs.
(2) Motorcycle Chain and Sprocket manufacturers tell you that the shape of the original sprocket chain socket is directly formed by forging, which has a large dimensional error, rough surface, and reduced wear resistance.
Motorcycle Chain and Sprocket manufacturers tell you that with the wide application of CNC machine tools and the reduction of processing costs, it is recommended to leave a little margin after forging and finish finishing by numerical milling to improve dimensional accuracy and surface roughness, so as to improve The purpose of wear resistance.
The above information is Motorcycle Chain and Sprocket Manufacturer's introduction and analysis of the sprocket improvement measures, hope it helps you.
