摘　　要：以RV减速器滚动轴承为研究对象,首先利用赫兹公式推导轴承在工作过程中的接触应力,然后利用ANSYS Workbench仿真轴承传动过程,分析轴承工作过程中的接触应力,将理论计算值与仿真分析的结果对比,两者具有良好的一致性.分析表明:利用ANSYS Workbench进行RV减速器滚动轴承的仿真分析,符合滚动轴承在径向载荷作用下受力和变形的实际情况.因此,有限元分析法为滚动轴承合理规划应力分布和可靠性设计提供了一种重要的途径.The RV reducer rolling bearing was taken as the research object.First,Hertz formula is used for deriving the contact stress in the process of rolling bearing in the work.Second,ANSYS Workbench is used to simulate the bearing drive process.Third,the contact stress of bearing is analyzed.And finally the theoretical calculation results are compared with the results of the simulation analysis,and the comparison shows that the two are in good consistency.The analysis shows that the result from the simulation analysis of the rolling bearing of RV reducer with ANSYS Workbench accords well with the actual situation of the stress and deformation of the rolling bearing under the action of radial load.Therefore,the finite element analysis method provides an important way for the rational planning of the stress distribution and the reliability design of the rolling bearing.
