| 摘 要： | 根据接触力学理论,用有限元法对预负荷实心和预负荷空心圆柱滚子轴承的径向刚度、滚子最大接触应力和轴承最大径向载荷进行了研究,分析了径向载荷对轴承的径向刚度、滚子最大接触应力的影响,结果表明,径向载荷不仅对最大接触应力有影响,而且对轴承径向刚度的也有显著影响;预负荷滚子轴承设计时一定要考虑载荷对轴承的径向刚度、滚子最大接触应力的影响为预负荷圆柱滚子轴承的设计与应用提供参考.

| Abstract: | In accordance with the theory of contact mechanics,the radial stiffness,maximum contact stress and maximum radial load of pre-loaded hollow and solid cylindrical roller bearings are simulated with finite element method.And the effects of radial load magnitude on the radial stiffness and maximum contact stress of the bearings are researched mainly.The results show that radial load magnitude does not only affect the maximum contact stress,but also affect the radial stiffness obviously.And these effects have b... |
