For parabolic spherical involute bevel gears, the spherical involute equations are constructed by analyzing the formation principle of spherical involute. The tooth lines wrapped around the surface of the base cone are obtained by using the spatial transformation of plane curves. The gear model is quickly constructed by combining it with the secondary development of UG. By changing the tooth profile equation, tooth profile modification can be achieved. The gear model before and after trim-ming is imported into Workbench for simulation. The meshing of the gears before and after re-shaping is analyzed under the same torque. The results show that the meshing condition of the gears after reshaping is better than that before reshaping, and the stress concentration is signifi-cantly improved, which enhances the service life of the gears. Meanwhile, the axial force of the shaped gear is smaller than that before shaping, which is favorable to the bearing life.
