Research Progress on the Friction Reduction Characteristics of Surface Texturing Modifications in Sliding Bearings
Sliding bearings are one of the core components of modern mechanical equipment. They have been widely used in engineering because of their stable and reliable performance,low working noise,convenient manufacture and variety of types. However,during operation,due to the influence of unstable working conditions,the bearing surface is prone to serious friction and wear,which can even lead to failure. Surface texture modification is one of the effective ways to solve this problem,as it has excellent performance in reducing friction and wear. In this paper,the research progress on the antifriction performance of sliding bearings with surface texture was summarized. The influence of the shape,arrangement,depth and area occupancy of surface texture on the tribological performance of sliding bearings was analyzed,and the antifriction performance when surface texture and other surface modification technologies were combined was summarized. The tribological properties after the application of surface texturing,reflected by the friction coefficient between mechanical parts,provided a reference for subsequent researchers in this field. Finally,existing research and future needs were considered to discuss the prospects for applying surface texturing in antifriction studies of sliding bearings.
