摘　　要：经典滚动轴承负荷分布的研究大多基于刚性套圈支承的假设,但用于柔性套圈支承的薄壁轴承存在较大误差。基于有限元分析软件ANSYS建立了薄壁深沟球轴承三维有限元分析模型,考虑外圈受载后弯曲变形对滚动体负荷分布的影响,分析载荷参数,轴孔配合间隙及滚动体个数等对轴承滚动体负荷及寿命的影响规律,分析结果与实验结果吻合度较高,说明运用该有限元方法对柔性支承套圈轴承进行性能分析是合理的,为进一步的性能分析及结构优化提供可靠的参考依据。The rigid ferrule hypothesis is usually used in the research on load distribution of ball bearings,but it has a relatively big error for thin-wall bearings which have flexible supported ferrules.The 3D finite element analytical model for thin-wall deep groove ball bearing is established by ANSYS.The effect of ferrule bending deformation under load on the load distribution of the rolling element is considered,and the change law of load distribution and life in different conditions is obtained,the results of finite element method are closed to the experimental values,which provide reference for the further performance analysis and optimization design.
