Research on Temperature Field of Hydrostatic Thrust Bearing with Annular Cavity Multi-Pad

Abstract:

A simulation research concerning temperature field of hydrostatic thrust bearing having annular cavities multi-pad was described in order to solve the thermal deformation of the hydrostatic thrust bearing with annular cavity multi-pad in the heavy CNC equipment. The Finite Volume Method of CFX has been used to compute three-dimensional temperature field of gap fluid between the rotation worktable and base. This study theoretically analyzes the influence of rotating velocity on the bearing temperature performance according to computational fluid dynamics and lubricating theory. It has revealed its temperature distribution law. The simulation results indicate that an improved characteristic will be affected by rotating velocity easily, and oil cavity temperature increases by gradually with rotating velocity enhancing. Through this method, the safety of a hydrostatic thrust bearing having annular cavities multi-pad can be forecasted, and the optimal design of such products can be achieved, so it can provide reasonable data for design, lubrication, experience and thermal deformation computation for hydrostatic thrust bearing in the heavy CNC equipment.
