Self-Compensated Precision Hydrostatic Rotary Bearing

Abstract:

A self-compensated hydrostatic rotary bearing is designed and manufactured. The bearing is modeled by fluid flow network method, and simulations are performed to predict the load carrying capacity. A hydrostatic bearing prototype has been tested and results show that it can achieve a stiffness of 120N/μm in radial direction and 220N/μm in axial direction under a supply pressure of 1 MPa, and its motion accuracy is 0.3μm. The designed bearing is suitable to be used in precision machines.
