采用数值计算方法分析了不同尺寸大小和位置的滚动轴承滚道表面凹坑对脂润滑油膜压力和油膜厚度分布规律的影响，并与光滑表面情况下的脂润滑油膜压力和厚度的分布进行了对比，最后采用扫描电子显微镜和能谱仪(EDS)对理论计算结果进行了验证． 结果表明:表面凹坑的存在使表面凹坑边缘位置存在油膜压力峰，而在表面凹坑中心
周围区域油膜压力急剧减小;表面凹坑润滑区域在靠近入口处一侧至靠近出口处一侧方向的润滑油膜厚度出现跃升现象，但相比于光滑表面，润滑脂油膜整体变薄;表面凹坑的尺寸大小和所处位置对油膜压力和油膜厚度的分布均有显著影响．

In this paper，the numerical calculation method is employed to analyze the effects of the surface dents in
rolling bearing raceways of different sizes and locations on the distribution of the oil film pressure and thickness in the state of grease lubrication． Then，the distribution is compared with that on a smooth surface． Finally，the results of theoretical analyses are verified by using a SEM and an EDS． The results show that (1) due to the existence of surface dents，the film pressure reaches the peak in the edges of the surface dents，while it decreases sharply in the central areas of surface dents; (2) the film thickness zooms in the lubrication areas of surface dents in the direction from near the entrance side to the exit side，but the film on the whole is thinner than that on a smooth surface; and (3) both the size and the location of surface dents have significant influences on the distribution of the oil film pressure and thickness．
