Study on the influencing factors of the deformation in the process of gear shaping

Ring gear is an important part of high power transmission system. Because of its thin wall and low stiffness, it is easy to cause deformation in the process of gear shaping, which affects its accuracy. Therefore, how to ensure the quality of gear ring gear insertion is an urgent research topic. In this paper, the influence of cutting parameters of gear shaper on the deformation of gear ring is studied by finite element simulation and practical test. The results show that the influence of main cutting parameters on the deformation of 42CrMo ring gear is radial feed, circumferential feed, stroke speed, and cutting depth. In the actual gear shaping process, the cutting parameters can be adjusted according to this deformation law, so as to control the deformation of the ring gear.
