摘　　要：根据接触力学理论,用有限元法对应用于盾构机主轴承的推力滚子轴承进行了动态分析,对分别采用圆柱滚子和圆锥滚子的推力轴承进行速度、接触力、接触应力和摩擦损耗等分析;研究结果表明,用推力圆锥滚子轴承代替推力圆柱滚子轴承应用于盾构机主轴承可以大大降低轴承的摩擦损耗.研究结果可为推力圆锥滚子轴承在大型重载机械中的应用提供研究基础和参考.The dynamic contact analysis of the thrust roller bearings with cylindrical roller and with tapered roller used in shields are respectively conducted based on Finite Element Method according to contact mechanics theory.The speed,contact force,contact stress and friction loss etc are analyzed.The results show that the replacement of thrust cylindrical roller bearings with thrust tapered roller bearings can greatly reduce the friction loss,which offers a research base and a reference to replace thrust cylindrical roller bearings with thrust tapered roller bearings in shields.
