The basic structure of a chain wheel includes the tooth section, the wheel body, and the shaft hole. The tooth section is the key part where the chain wheel engages with the chain, and its shape and size determine the performance of the chain wheel. The wheel body is the main part of the chain wheel, used to support the tooth section and transmit torque. The shaft hole is the part where the chain wheel connects to the shaft, and its size and shape need to match the shaft.
