【摘要】 通过求出在径向力和轴向力作用下高铁轴承的载荷分布,分析高铁轴承内部两列滚子的载荷分布情况,确定轴承受力最大的滚子,计算滚子与滚道间的表面接触应力,进而求出次表面Von Mises应力分布。然后利用I-H寿命计算模型,改变相关参数值,分析高铁轴承的滚子长度、滚子平均直径及轴承节圆直径对轴承次表面Von Mises应力及疲劳寿命的影响,为高铁轴承使用、设计和制造提供相关参考。更多还原

【Abstract】 This paper solves the contact load distribution of the two rows of rollers of the high-speed railway bearing under the action of radial and axial forces,to determine the roller which carried the maximum contact load,and calculates the surface contact stress between the roller and the raceway,and then calculates the Von Mises stress distribution on the subsurface.Then,this paper uses the I-H life calculation model to analyze the influence of the roller length of the high-speed bearing,the average diameter of the roller and the diameter of the bearing pitch on the Von Mises stress on the subsurface and fatigue life of the bearing by changing the relevant parameter values.更多还原
