Influence of Texture Parameters on Lubrication Performance of Surface Textured Bearings

As an important supporting part of rotating machinery, bearing is widely used in rotating machinery and equipment. In order to explore the influence of working conditions on the texture bearing, the simulation analysis and experiment are used. By three-dimensional micro-texture journal bearing model considering cavitation effect, the influence of rotational speed and viscosity on the oil film pressure, bearing capacity, friction coefficients of texture bearing is studied. Simulation results are verified by different working conditions in experiment. The results show that the higher the viscosity of lubricating oil is, the better the lubrication performance will be. As the rotational speed increases, the friction coefficient of the bearing first decreases and then increases. © 2021, Chinese Mechanical Engineering Society. All right reserved.
