Even teeth: pitch circle diameter plus roller diameter, odd teeth, pitch circle diameter D*COS(90/Z)+Dr roller diameter. The roller diameter is the diameter of the rollers on the chain. The measuring column diameter is a measuring aid used to measure the tooth root depth of the sprocket. It is cylindrical and as large as the roller diameter. The measuring column measuring distance is used to measure the tooth root depth. a measurement data.
Extended information:
According to different meshing mechanisms, it can be divided into external meshing round pin toothed chains and Hy-Vo toothed chains, internal meshing round pin toothed chains and Hy-Vo toothed chains, internal and external compound meshing round pin toothed chains And Hy-Vo toothed chain, internal-external compound meshing + internal meshing round pin toothed chain, orderly arranged outer meshing + inner-outer compound meshing round pin toothed chain and Hy-Vo toothed chain;
According to the structure of the toothed chain guide plate, it can be divided into external guide toothed chain and internal guide toothed chain; according to the shape of the toothed chain guide plate, it can be divided into ordinary guide plate toothed chain and butterfly guide plate toothed chain;
According to the assembly method of the toothed chain, it can be divided into a toothed chain without a leaf spring and a toothed chain with a leaf spring; in the Hy0-Vo toothed chain series. According to the shape of the chain plate hole and the shape of the pin shaft, it can be divided into Hy-Vo toothed chain with circular reference hole and non-circular (apple-shaped. Long waist-shaped reference hole Hy-Vo toothed chain.
For toothed chain sprockets. According to different tooth shapes, it can be divided into involute toothed sprocket, straight line toothed sprocket, arc toothed sprocket, etc.; according to different transmission forms, it can be divided into single-row sprocket, double-row sprocket, and multi-row sprocket. Sprockets, etc.; according to the different forms of tooth tip arcs, it can be divided into non-top-cut sprockets and top-cut sprockets;
According to the structure of the toothed chain guide plate, it can be divided into external guide sprocket and internal guide sprocket; according to the sprocket processing method, it can be divided into hobbing sprocket, milling sprocket, shaper sprocket, powder metallurgy sprocket, etc. .
