摘　　要：随着齿轮研究的不断进步,许多新型齿轮不断涌现,其中尤以面齿轮为代表。由于面齿轮在高速重载下的传动优点,其在航空传动件中有很大的应用潜能。根据齿轮接触分析(TCA)原理,求解正交直齿面齿轮的接触轨迹与接触椭圆;利用点接触赫兹理论,计算正交面齿轮理论接触应力;运用ABAQUS对正交面齿轮进行有限元分析,得到面齿轮接触应力的仿真结果。理论计算与仿真结果的对比验证了该计算方法的正确性。With the continuous progress of the gear research, many new gears are constantly emerging. Particularly face gear is representative. Because of the advantages of face gear transmission under high speed and heavy load, it has great application potential in aerospace transmission. According to tooth contact analysis （TCA） theory, contact trajectory and contact ellipse of the orthogonal face gear were solved. Using Hertz theory of point contact, the contact stress of orthogonal face gear surface was calculated. Using ABAQUS, the simulation results of face gear contact stress could be obtained. The comparison between theoretical and simulation re- suits verifies the validity of theoretical analysis.
