摘　　要：根据接触力学理论,利用有限元软件ABAQUS,合理建立了空心圆柱滚子轴承的分析模型,研究了某高速空心滚子轴承的应力分布情况,并对滚子的空心度进行了优化设计。结果表明:在一定工况条件下,只要空心度合适,空心圆柱滚子轴承的应力分布情况要远好于实心滚子轴承。研究结果为高速空心圆柱滚子轴承的设计提供了指导。According to the theory of contact mechanics,the finite element analysis model of hollow cylindrical roller bearings was built in ABAQUS,the stress distribution of high speed hollow roller bearings was studied,and the roller＇s hollow ratio was optimized.The results show that if roller＇s hollow ratio is proper,the stress distribution of hollow roller bearings is much better than ordinary solid roller bearings,which could provide guidance to the design of high speed hollow cylindrical roller bearings.
