Modal Analysis of Liquid Hybrid Bearing in the Spindle System of High-Speed Roll Grinder

Abstract:

Mode analysis of liquid hybrid bearing in the spindle system of high-speed roll grinder whose grinding wheel linear velocity is 80 m/s is carried out by means of finite element analysis method, and the vibration vulnerable areas of the liquid hybrid bearing are found out near the static pressure oil cavities and the diversion groove, and the former 6 orders natural frequencies are gained, furthermore, each order vibration mode is mainly presented as torsion deformation. Therefore, in order to avoid resonance vibration, the bearing should keep away from the resonance vibration frequency region in the course of practical working, and its dynamic performance can be enhanced by optimizing the structure or improving the material property of the bearing, thus, theoretical supports for developing the liquid hybrid bearing in the spindle system of high-speed roll grinder are provided.
