中文摘要:
      针对固体润滑角接触球轴承的润滑磨损寿命无法精确预测问题,提出一种更为准确的基于动载荷分布的磨损寿命计算模型,并考虑内、外圈载荷同时作用下的动载荷分布。建立内、外圈和滚道之间的动载荷计算模型,更准确地表征角接触轴承运动接触特性,同时将轴承整个零部件的动载荷分段计算方法与磨损计算模型相结合,建立考虑轴承整体接触区动载荷分布下的磨损模型,为轴承承载运行下的磨损寿命机制分析提供参考。
英文摘要:
      Aiming at the problem that the lubrication wear life of solid lubricated angular contact ball bearings can not be accurately predicted, a more accurate calculation model of wear life based on dynamic load distribution method was proposed, and the dynamic load distribution under the action of inner and outer ring loads was considered. Through the established dynamic load calculation model between the inner and outer rings and the raceway, the moving contact characteristics of the angular contact bearing were more accurately characterized. At the same time, the dynamic load segment calculation method of the entire bearing component was combined with the wear calculation model to establish the bearing wear model under the dynamic load distribution of the overall contact area. It provides reference for the wear life mechanism analysis under the bearing operation.
