Abstract: Thermal-phase transformation-strain/stress multi-physical coupled model was established for die quenching process of 9310 steel spiral bevel gear by finite element software, and the numerical simulation of die quenching process was carried out. The results show that the design of mold has significant effect on die quenching distortion. The distortion of gear is obviously reduced by optimization of assembly dimensions and pressure angle of the mold. The eccentricity of upper and lower mold causes the distortion of gear, while it can be avoided by adjustment of core mold dimensions.

Key words: 9310 steel, spiral bevel gear, die quenching, numerical simulation, heat treatment distortion
