摘　　要：对传动齿轮受载齿轮面上的接触力和应力进行了接触有限元分析,模拟齿轮副在啮合过程中因弹性接触变形所引起的齿面载荷分布不均的问题.应用磨齿计算调整法进行齿廓修形,模拟实际工况参数,对修形齿轮副进行有限元分析,探测得出齿轮副啮合齿对的齿面接触应力和接触载荷数值结果.结果显示,使用磨齿计算调整法进行齿廓修形,可在一定程度上减少齿间载荷波动现象,使接触齿对在传动全过程始终保持共轭啮合状态,进而实现齿轮传动的平稳连续进行.By carrying out finite element analysis of contact force and stress on being loaded gear surface of gear pair, non-uniform load distribution on gear surface caused by elastic contact deformation of gear pairs in meshing process is simulated. According to tooth profile modification of gear grinding calculation modified method, by conducting finite element analysis of modifying gear under the parameter conditions, the contact stress results and contact force results of modifying gear pair are obtained. The finite element analysis demonstrates that profile modification method, to a certain extent continuously decrease load variation in meshing processeach and eliminate the phenomenon of load fluctuation on each teeth. It keeps gear teeth conjugate meshing in the whole transmission process, eventually smooth the meshing procedures.
