摘　　要：齿轮轴的结构较普通轴复杂,使用传统方法对实际容易破坏的部位进行确定比较繁琐,并且校核计算结果与实际情况相差较大。分别用以第三强度理论为基础的传统方法和以第四强度理论为基础的有限元法,对某二级减速器高速级齿轮轴结构进行分析,并比较两种结果的差异。结果表明:用传统方法对减速器齿轮轴进行校核时忽略了中间主应力对材料的破坏影响,计算结果偏于安全;而用有限元法对减速器齿轮轴进行校核考虑了相应的影响,更加符合齿轮轴实际工作时的受力状况。The structure of gear shaft is more complex than common shaft. It＇s tedious to determine the actual portion which is easy destroyed by the traditional method, and the result of checking calculation is quite different from the actual situation. It analyzed the high-speed gear shaft structure of a two-stage reducer by both the traditional method basing on the third strength theory and the finite element method basing on the fourth strength theory respectively, and compared the difference between the two methods. The results show that the conventional method ignores the damaging effects of the intermediate principal stress on the material, and the calculated date are on the safe side. However, the finite element method considers the corresponding impact and is more compliant for the actual work force condition of the eear shaft.
