Sprocket is one of the important parts of the scraper conveyor. Its characteristics have a direct impact on the service life of the scraper conveyor. The sprocket drive used in the sprocket wear analysis is the ordinary traction sprocket, which has relatively large sliding motion at the engagement, and the working conditions are poor, which will cause serious wear.

Sprocket is a kind of wheel with cogged sprocket, which is used to mesh with the block with accurate pitch on the chain link or cable. Sprockets are widely used in chemical industry, textile machinery, escalators, wood processing, three-dimensional parking garages, agricultural machinery, food processing, instrumentation, oil and other industries.
