Research on Dynamic Pressure of Hydrostatic Thrust Bearing Under the Different Recess Depth and Rotating Velocity

Abstract

In order to solve the loading capacity of the hydrostatic thrust bearing, a numerical simulation concerning dynamic pressure of multi-pad hydrostatic thrust bearing under the different recess depth and rotating velocity is been described. Three-dimensional dynamic pressure field of gap fluid between the rotational worktable and the base has been simulated by using the Computational Fluid Dynamics. This study theoretically researches the influence of recess depth and rotating velocity on dynamic pressure of the bearing according to the lubricating theory and Finite Volume Method, and the simulation results indicate that an improved characteristic will be affected by recess depth and rotating velocity easily. Through this method, the optimal loading capacity of such products can be achieved. © 2014 SERSC.
