摘　　要：建立了正交面齿轮的三齿几何模型 ,形成了相应的有限元分析模型 ,研究了在不同参数下 (如模数、齿数、齿宽 )正交面齿轮三齿模型的最大弯曲应力特性。本文考虑面齿轮受载最不利的情况 ,即在面齿轮的齿顶沿齿宽方向的不同位置加集中载荷 ,通过有限元分析表明 ,面齿轮的最大弯曲应力不是在齿根而是在沿齿高方向的中部位置 ,并随力的作用点向两端移动时最大弯曲应力的位置向齿顶移动。Three-tooth solid model of face gear and the corresponding finite element model are formulated. In different transmission fac tors (modulus, tooth number, tooth length), the characteristics of maximum bendi ng stress in three-tooth model of perpendicular face gear are investigated. The worst loaded face gear is analyzed, that is, the concentrated load is applied o n the top of face gear along the different locations of tooth length. Finite ele ment analysis indicates that the maximum bending stress location in perpendicula r face gear is not in tooth root, but in the middle of the tooth surface along t he tooth height, and moves towards the tooth top with the location of meshing mo ving towards two ends. This investigation is important to control the contact po ints in the design of face-gear drive.
