THE FORMING MECHANISM AND ELIMINATING MEASURES OF TOOTH DIRECTION ERRORS DURING AXIAL SHAVING PROCESS

A tooth direction error is the main index to evaluate the contact precision of a gear. It affects the bearing capacity and noise of a gear directly. The practice of production in one of the domestic factories shows that almost above half of the unqualified gears in contact region after shaving are made beacuse of tooth direction errors. Therefore, the tooth direction error during shaving gears is a very important problem. This paper tries to analyze the reasons, cheracteristics and mechanism of forming tooth direction errors from the view of geometry and kinematics, and puts forward the proper eliminating measures in order to insure the production quality, reduce the production cost and increase the productivity.
