【Abstract】 The tooth surface optimization of the gear pair was studied based on the toprem tool in order to improve the meshing quality of spiral bevel gear effectively. First of all, a mathematical model of the toprem tools blade profile was constructed. The geometry design parameters of the cutting tools were designed and optimized. The mathematical model of gear pair surface was constructed based on this. The effect of cutting tools on the tooth surface contact stress was analyzed based on the finite element software. Finally, in order to further verify the effects of the toprem tools, a lot of process and rolling experiments were performed. The results showed that, the meshing quality of the spiral bevel gears could be improved greatly while using the reasonable toprem tools.更多还原
