Abstract:
To improve the loading capacity, antifriction performance, and the dynamic characteristics of journal bearing, the composite micro-texture journal bearing is studied, the influence of surface roughness and texture arrangements on the micro-textured bearing is further considered. The surface roughness model, the oil film thickness equation of composite micro-texture, the generalized Reynolds equation of journal bearings, the dynamic characteristics calculation model of micro-textured bearing rotor system is established. The static and dynamic characteristics of bearing with different distribution position, arranges of composite micro texture considering surface roughness are studied. The results show that the proper roughness can improve the lubrication performance of bearing, and the lubrication performance is better when the roughness value is 0.209μm. The composite micro-texture is distributed around 160 °, and the triangular composite diamond micro-texture bearing has good stability and lubrication performance. When the micro-textures arrange in parallel along the circumference considering surface roughness, better static and dynamic characteristics are gained.
