摘　　要：采用有限元方法对深沟球轴承进行摩擦接触分析,得到深沟球轴承的接触应力、接触变形量、径向变形量及相对滑移分布规律,研究结果与赫兹理论计算结果的吻合程度较好,证明了有限元分析方法的可靠性。分析了载荷、摩擦系数对轴承接触应力、接触变形量、相对滑移量和径向变形量的影响,结果表明,轴承的接触应力、接触变形、径向变形量和相对滑移量随载荷的增加而增大,而随摩擦系数的增加而减小。Based on finite element method, the contact property of groove ball bearing is analyzed, the contact stress, contact deformation, radial deformation and relative slip distributions of groove ball bearing are obtained, and the reliability of computation result obtained by finite element method is proved, compared with the Hertz theory. The influence of load and friction coeffi- cient on the contact characteristics of ball bearings is analyzed. The results show that the contact stress, contact deformation, radial deformation and relative slip of the bearing increase with the increase of load, but decrease with the increase of friction coefficient.
