一、引言滚动轴承有很多优点,在国民经济各部门中得到广泛的应用,对滚动轴承的选择和寿命计算至今都是建立在轴承壳体、座圈、心轴完全刚胜、径向间隙为零以及半数滚动元件承受负荷等理想条件基础上的,从而得出滚动体接触力的余弦分布及其最大峰值发生在中间最低位置滚动体上等结论。实际上,无论是用于高转速还是低转速情况的各类滚动轴承,其壳体 I. Introduction Rolling bearings have many advantages in various sectors of the national economy has been widely used, the choice of rolling bearings and life calculations so far are built on the bearing housing, seat ring, mandrel completely just won, the radial clearance is zero and Half the number of rolling elements to withstand load and other ideal conditions based on the rolling contact body resulting in the cosine distribution of the maximum peak and the peak occurred in the middle of the lowest position on the rolling conclusion. In fact, both for high-speed or low-speed conditions of various types of rolling bearings, the shell
