Sprockets are widely used in mechanical transmission in chemical industry, textile machinery, escalators, wood processing, multi-story parking garages, agricultural machinery, food processing, instrumentation, petroleum and other industries.

[0003] In order to reduce the wear on the sprocket, make the transmission more stable and greatly improve the transmission efficiency, a sprocket (see patent number: 201520927604.0 for details) is developed. The sprocket includes a sprocket body, which is characterized in that both end surfaces of the sprocket body are covered with elastic modules, and the sprocket body is provided with a through hole that connects the elastic modules on the two end surfaces as one, and the elastic module on one end surface is provided with a groove, and the groove cooperates with the positioning piece that fixes the sprocket body. This noise-reducing sprocket that can cooperate with the positioning piece for transmission can not only reduce noise and reduce the wear on the sprocket, but also make the transmission more stable, thereby greatly improving the transmission efficiency.
