Product Introduction
A sprocket is a toothed mechanical wheel designed to engage with a chain to transmit power and motion. It is the core component of a chain drive system, typically used in conjunction with a roller chain. The most notable feature of a sprocket is its ability to provide precise synchronous drive, maintaining a constant speed ratio between the driving and driven shafts without slippage. Compared to gear drives, chain drives are suitable for applications with relatively long distances between shafts and can transmit substantial power. Consequently, sprockets are widely used in bicycles, motorcycles, automotive timing systems, conveyors, and various agricultural and industrial machinery. They are usually manufactured from high-strength steel or cast iron and often undergo heat treatment to enhance wear resistance and service life.
