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.

Chain wheels are widely used in various industries, including but not limited to mechanical transmission in chemical, textile machinery, escalators, wood processing, three-dimensional parking garages, agricultural machinery, food processing, instrumentation, petroleum and other industries.
