为了明晰不同工况参数对圆锥滚子轴承磨损的影响规律,开展了圆锥滚子轴承磨损研究。建立了包含滚子平衡方程与内圈平衡方程的圆锥滚子轴承拟静力学模型,基于Archard磨损理论推导建立了适用于圆锥滚子轴承磨损分析的磨损深度计算模型;对比分析了轻载、中载和重载3种服役工况条件下,轴承内、外滚道和滚子的磨损分布特征。结果表明,圆锥滚子、内外滚道在接触线上的磨损深度均呈现双峰分布特征,外滚道磨损分布与滚动体位置密切相关;轻载工况下,轴承转速提高25%,轴承滚道与滚子磨损峰值提高20%;重载工况下,轴承载荷提高16%,轴承滚道与滚子磨损峰值提高17%以上。3种工况下轴承磨损峰值对比表明,轴承等效载荷与转速的乘积并非控制轴承磨损的决定因素,载荷变化对于轴承磨损有着较为显著的影响。
In order to clarify the influence of different working conditions on the wear of tapered roller bearings
the wear state of tapered roller bearings was carried out.A quasi-statics model of tapered roller bearings including roller balance equation and inner ring balance equation was established
and a wear depth calculation model suitable for wear analysis of tapered roller bearings was derived based on Archard wear theory.The wear distribution characteristics of bearing inner and outer raceways and roller elements under light load
medium load and heavy load conditions were comparative analyzed.The results show that the wear depths of the tapered roller and the inner/outer raceways on the contact line show bimodal distribution characteristics
and the wear distribution of the outer raceway is closely related to the positions of the rolling elements.For light load condition
the peak wear depth of bearing raceways and roller elements increases by 20% as bearing speed increases 25%
and for heavy load condition
the peak wear depth of bearing raceways and roller elements increases more than 17% as bearing load increases 16%.The comparison of bearing wear peaks under the three working conditions shows that the product of the equivalent load and the speed of the bearing is not the determining factor controlling bearing wear,and the load change has a significant impact on the bearing wear.
