摘要：
Optimizing the structure of the spiral bevel gear can effectively reduce the weight of the gear, bearing and box shell of axle reducer. A spiral bevel gear with a large pressure angle at driving side and a standard one at coast side is presented. The equations of spherical coordinates of tooth profile for spiral bevel gear with double pressure angles are proposed. Based on the design parameters of symmetric spiral bevel gear of SUV rear axle reducer, the 3D model of spiral bevel gear with double pressure angles in PRO/E is built. The contact model of finite element is established, and then the tooth face contact stress is analyzed. The inside and outside blades are designed for cutting driving gear and driven gear of spiral bevel gear with double pressure angles, and the spiral bevel gear pair with double pressure angles are manufactured. The experiment of fatigue life is carried on by the closed test bench. The experimental result shows that the fatigue life of spiral bevel gear with double pressure angles for lightweight 25% conforms to the requirements of the standard, and the fatigue life is higher than the one of SUV rear axle reducer. The correctness of finite element analysis result is verified and a practicable method is provided for lightweight technology of vehicle transmission. © 2015 Journal of Mechanical Engineering.
