Abstract：Aiming at the problems of low machining efficiency and insufficient fatigue strength of spiral bevel gear,a numerical simulation and parameter optimization method for warm rolling forming of spiral bevel gear pinion was proposed.Based on deform-3D finite element simulation software,the influence laws of technological parameters such as friction factor,feed speed and initial rolling temperature on the forming stress and strain of the pinion during warm rolling were analyzed.Combined with orthogonal test,the optimization of process parameters was completed,and the warm rolling forming test of the pinion was carried out by using the best combination of process parameters.The tooth surface and pitch are tested.The results show that the total deviation of convex surface and concave surface are 14.4 μm and 14.1 μm.The cumulative total deviation of gear pitch is 57.0 μm and 56.3 μm and the accuracy level has reached to GB 8.The accuracy of tooth surface and pitch of gear meets the requirements of gear grinding after heat treatment.
