摘要：
In order to reveal influences of tooth surface wear on face gear transmission, the face gear pair tooth contact analysis method combining with adhesive wear formula was proposed. The relative displacement and contact stress on the contact elliptical discrete points of face gear pair were obtained by using tooth contact analysis，and wear depth was obtained from adhesive wear formula. The face gear pair tooth surface coordinate with wear was compiled, and systematic meshing stiffness under different wear was calculated in ABAQUS. Tooth surface wear was equivalent to tooth surface deviation，influence of different wear on static transmission error was discussed. Face gear pair' s normal and wear dynamic responses were compared，and torsional influences on wear was analyzed. The results show that gear wear mainly affects amplitude of meshing stiffness and transmission error, leading to the rapid rises of acceleration and meshing force amplitude. The increase of torque aggravates wear. Compared with the dimensionless statistical index, the root mean acceleration square is more sensitive to wear faults. © 2023 Chinese Vibration Engineering Society. All rights reserved.
