摘要

The meshing stiffness, load sharing, and transmission error of a gear pair depend on the shape of the profiles in contact. Since the profile shapes change with the surface wear due to friction, the meshing stiffness, load sharing, and transmission error of the gear pair change accordingly, and this change is different depending on the number of meshing cycles. This means that the tip relief, which was calculated to avoid the mesh-in impact and control the induced dynamic load for the initial tooth geometry, may not be optimal for worn teeth. In this paper a study of the influence of surface wear on the meshing stiffness, load sharing, and transmission error of internal spur gears is presented. The optimal tip relief for minimizing the peak-to-peak amplitude of transmission error considering wear is also investigated.
