针对单个空心圆柱滚子的接触情况及相应的轴承载荷分布问题进行了理论探讨。结果表明 ,无论是单个滚动体的最大接触应力 ,还是整个轴承的载荷分布情况 ,空心圆柱滚子轴承都优于相应的实心圆柱滚子轴承 ,但在重载场合下使用时必须避免发生内孔壁的弯曲疲劳破坏。附图 4幅 ,表 4个 ,参考文献 8篇。 Aiming at the contact condition of a single hollow cylindrical roller and the corresponding bearing load distribution, a theoretical discussion is made. The results show that the hollow cylindrical roller bearings are better than the corresponding solid cylindrical roller bearings, whether it is the maximum contact stress of a single rolling element or the load distribution of the entire bearing. However, when used under heavy loads, the inner holes must be avoided Wall bending fatigue damage. Figure 4, Table 4, 8 references.
