Research and prospect of textured sliding bearing

The sliding bearing belongs to the supporting parts with high application rate in engineering, but in the operation process, it is inevitable to encounter large friction and wear due to the thin lubricating oil film and excessive applied load, which will seriously or even lead to failure. Surface texture is an effective method to solve this problem. At present, a large number of scholars have studied this. This paper summarizes the conventional texture shape and new shape design of surface texture of radial and thrust sliding bearings, and puts forward ideas for the extensive application of composite texture and bionic texture in sliding bearings. The arrangement position of texture in sliding bearing was summarized regularly, and the optimization problem of texture parameters on bearing surface was discussed, and the optimal parameters of partial texture were obtained. At the same time, the effects of different working conditions on texture performance and the synergistic effect of different types of lubricants on texture are summarized. The research on the synergistic technology of texture and surface technology for materials used in sliding bearings is briefly summarized. The application of this technology in sliding bearings needs further research. Finally, the above contents are summarized, and the existing problems of texture treatment on the surface of sliding bearings are put forward. Combined with the development of texture in many fields, the future development prospects of textured sliding bearings are put forward.
