摘要：

根据组合创新原理，通过对圆柱滚子轴承的结构进行创新研究,提出了一种在空心圆柱滚动体中嵌入聚四氟乙烯(PTFE)材料的弹性复合圆柱滚子轴承新结构的设计方法。为确定弹性复合圆柱滚动体的结构尺寸,定义滚动体的填充度K=d/D(D为滚动体直径,d为材料填充直径),用ANSYS软件对弹性复合圆柱滚子轴承进行有限元建模,分析了重载工况下弹性复合圆柱滚子轴承的接触应力、von Mises应力、弯曲应力以及变形量对滚动体结构尺寸的影响。结果表明,在重载工况下,弹性复合圆柱滚子轴承滚动体填充度最优值为55%，并通过试验验证了分析结果的正确性。所得结果为弹性复合圆柱滚子轴承的设计提供了基础性数据。

Abstract:

According to the principle of combinational innovation,a study of structure innovation of cylindrical roller bearing was made,and a new method of structure design of elastic composite cylindrical roller bearing which embedded PTFE in the hollow cylindrical roller was put forward.In order to determine the size of elastic composite cylindrical roller and define the rolling element filling K=d/D,ANSYS software was used in finite element modeling of the bearing.Analysis was made to identify the influence of the contact stress,von Mises stress,bending stress and load of elastic composite cylindrical roller bearing on overloaded.It is found that the best rolling element filling is 55% in the overloaded case.The accuracy of the analysis was verified through the experiments.The study results provide the basic data for the design of elastic composite cylindrical roller bearing.

Key words: elastic composite cylindrical roller bearing, filling degree, finite element analysis, contact stress, bending stress
