Surface micro texture technology is a technology to improve the surface lubrication performance of friction pairs. The research on the micro texture thrust bearing mainly focuses on the effect of roughness on the lubrication performance of bearings or the effect of single micro texture on the lubrication performance of bearings. To improve the lubrication performance of friction pairs, the effect of different composite micro-texture parameters on the performance of thrust bearings considering roughness was studied. At the same time, experiments were used to further illustrate the anti-friction mechanism of the micro-texture. Based on the surface roughness model, water film thickness equation of composite micro-texture and the generalized Reynolds equation of thrust bearings, the performance of thrust bearings with different composite micro-texture shapes and arrangements was studied. The effect of composite micro-texture shapes on bearing lubrication performance was verified by friction experiments.
