As a new gear product, the sprocket has a high transmission speed. In its specific application process, due to its high speed advantage, the noise generated is very small, which is also conducive to achieving a good processing environment. In its application, the sprocket not only has a relatively high installation accuracy, but also has an ideal machining accuracy, which saves a lot of trouble for future maintenance work. Moreover, the advantages of the compact structure of the sprocket make it have a larger transmission ratio, and the service life of the sprocket is relatively high.
