Numerical Simulation of Temperature Field of Hydrostatic Thrust Bearing with Sector Cavity
In order to solve the thermal deformation of the hydrostatic thrust bearing, a simulation research concerning temperature field of hydrostatic thrust bearing having sector cavities was described. The Finite Volume Method 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 cavity radius and cavity depth on temperature of the gap flow according to computational fluid dynamics and lubricating theory. It has revealed its temperature distribution law. The simulation results indicate that an improved characteristic can be gotten from a hydrostatic thrust bearing having sector cavity, oil cavity temperature decreases by gradually with cavity radius enhancing, oil cavity temperature decreases by gradually with cavity depth. Through this method, the safety of a hydrostatic thrust bearing having sector cavities can be forecasted, and the optimal design of such products can be achieved, so it can provide reasonable data for design and lubrication and experience and thermal deformation computation for hydrostatic thrust bearing in the heavy equipment.
