摘　　要：针对在右转弯工况下轮毂内侧轴承可能出现应力集中的问题,提出内外滚道全圆弧修形、滚子对数修形的改进措施,优化后轴承应力集中现象得到改善。同时,对轴承最佳预紧量进行优化设计,进一步提高了轮毂轴承使用寿命。In view of possible stress concentration of bearings inside hub under right turning condition,the improvement measures of full arc profiling of inner and outer raceways and logarithmic profiling of rollers are put forward,and the stress concentration of the bearings is improved after optimization.At the same time,the preload of the bearings is optimally designed to further improve the service life of hub bearings.
