Chain wheels are widely used in various industries, including but not limited to chemical, textile machinery, escalators, wood processing, three-dimensional parking garages, agricultural machinery, food processing, instrumentation, petroleum equipment, etc. In these industries, sprockets are used to drive various equipment and achieve power transmission and conversion.

A sprocket is a wheel with embedded teeth designed to engage with accurately spaced blocks on a chain link or cable, enabling the transmission of power. The tooth profile of a sprocket is designed to ensure that the chain enters and exits the engagement smoothly and effortlessly, while reducing the impact and contact stress during engagement.
