Tooth profile modification (TPM) optimization design has got extensive attention in the design of gear system. To ensure the accuracy of the tooth contact analysis (TCA) and the optimization of the modification parameters, the paper established a 3D finite element model (FEM) of the helical gear with TPM. Loaded TCA and stress calculations of helical gears are carried out precisely. The effects of the modification parameters on transmission error (TE), mesh stiffness, tooth bending, and contact stress of the helical gear are analyzed. The tooth surface modification optimization is conducted. The results indicate that the optimized modification parameters can greatly improve the smoothness of gear transmission, which lays the foundation for the design of low vibration and noise transmission system.
