在高速和轻载工况条件下，打滑擦伤往往成为圆柱滚子轴承的主要失效形式，而表面粗糙度对轴承打滑损伤有很大的影响。本文采用部分弹性流体动力润滑理论，分析了在表面粗糙度影响下，轴承润滑膜厚比以及轴承表面加工纹理与轴承保持架滑差率的关系，从而揭示表面粗糙度效应对高速滚子轴承运动性能的影响 Under high-speed and light-load conditions, the sliding abrasion often becomes the main failure form of the cylindrical roller bearing, and the surface roughness has a great influence on the bearing slipping damage. In this paper, the partial elastic fluid dynamic lubrication theory is used to analyze the relationship between bearing lubrication film thickness ratio and bearing surface machining texture and bearing cage slip under the influence of surface roughness, so as to reveal the effect of surface roughness on high speed roller bearing motion The impact of performance
