Sprocket is a toothed circular mechanical component typically used in conjunction with a chain to transmit power and motion. Its tooth profile is precisely designed to match the links of the chain, enabling efficient power transfer through meshing. Sprockets are usually made of high-strength metals such as steel or cast iron, offering durability and high load-bearing capacity. They are widely used in bicycles, motorcycles, industrial equipment (such as conveyor belts and lifting machinery), and agricultural machinery (such as tractors and harvesters). Compared to belt pulleys, sprocket drives are more suitable for high-load and high-precision applications, although they tend to generate more noise during operation and require regular lubrication and maintenance.
