Study on the Influence of Surface Texture on the Dynamic Performance of Sliding Bearing

Abstract

Rotor bearing system is an important part of mechanical equipment. The vibration of equipment caused by rotor system has become a more important problem in engineering. In this paper, the texture technology of the inner surface of the bearing is studied to explore the influence of the surface texture on the vibration reduction characteristics of the bearing. The results show that reasonable texture parameters and texture distribution can reduce the friction of the bearing and increase the end discharge. There is an optimal texture density and texture region. In this paper, a bearing test platform is set up to test and study the tiles with different surface texture. The test results show that the amplitude of the axis orbit of the sliding bearing with texture is significantly reduced, the principal stiffness and cross stiffness of the textured bearing are larger than those without texture, the damping is slightly larger under high speed and light load than that without texture, and the texture has obvious damping effect on the bearing shell.
