摘要

This paper proposes a design for a self-compensating restrictor for hydrostatic bearings. The proposed restrictor consists of a compensation block and two disc springs and offers the advantages of self-sensing compensation and easy installation. First, interrelated theories are presented on the self-compensating restrictor installed within the hydrostatic bearing. Second, equations are derived that govern the dimensionless relationship between the stiffness, gap, and resistance of the bearing land and the eternally applied load on the bearing. Influences of the design parameters on bearing performance and the feasibility of the design are then assessed both analytically and experimentally. The results of the theoretical analysis are then compared with the experimental results. These demonstrate that the proposed restrictor exhibits superior performance in terms of stiffness and load-carrying capacity. Furthermore, it has the advantage of simplicity in its manufacture and assembly.
