The sprocket gear teeth are the part of the sprocket that directly participates in the meshing work. Its shape should ensure that the chain can enter and exit the mesh freely and smoothly, and be as simple as possible to facilitate processing. Introduce the analysis of common problems when machining shafts with non-standard sprocket: (1) The combined force of the radial cutting force generated during cutting and the radial component force of the clamping will cause the workpiece to bend and cause vibration when the workpiece rotates, thereby affecting the machining accuracy and surface quality. (2) When the workpiece rotates at a high speed, the bending and vibration of the workpiece are aggravated due to the centrifugal force. (3) The self-vibration of the workpiece is aggravated due to the deformation of the workpiece due to its own weight, which affects the processing accuracy and surface quality. (4) The steel quenching and tempering treatment causes the bending and deformation of the blank, which seriously affects the subsequent turning processing, so it needs to be straightened, which increases the processing cost.
