修形圆柱滚子轴承滚子凸度量设计

Design of Roller Crowning of Cylindrical Roller Bearings

用有限元方法对圆柱滚子轴承的修形滚子的凸度量进行了研究,分析了凸度量对接触应力和等效应力的影响,结果表明,修形滚子降低边界应力集中的效果不但与凸度量有关,而且还与轴承所受载荷大小有关,因此,设计凸度量时必须考虑轴承的实际载荷工况.

The roller crowning of Cylindrical Roller Bearings is analyzed by finite element method.The effect of roller crowning on contact stress and equivalent stress is studied.The results show that the effect of roller crowning on contact stress and equivalent stress is related to the magnitude of the load applied on the bearing.Therefore, the influence of the load magnitude must be considered in order to obtain reasonable roller crownings.
