Basic knowledge of drive sprocket

　　   The sprocket is divided into a driving sprocket and a driven sprocket. The driving sprocket is installed on the output shaft of the engine in the form of splines; the driven sprocket is installed on the driving wheel of the motorcycle.chain条将动力传递给驱动轮，一般主动链轮比从动链轮要小，可起到降速增扭的效果。

　　Performance characteristics of drive sprocket

　　①The selection of materials-both the large sprocket and the small sprocket are made of high-quality carbon structural steel for stamping and forming.

　　②Machining and processing technology-the use of advanced milling processing technology to make the tooth profile more accurate.The entire sprocket has undergone quenching and tempering heat treatment, which greatly improves its comprehensive mechanical properties. The tooth profile hardness is above 68-72HRA, which significantly improves the wear resistance of the sprocket.

　　③Product series-economical and practical ordinary sprocket and superior quality sprocket.
