Analysis of the Static Characteristics of a Self Compensation Hydrostatic Spherical Hinge

Abstract

This technical brief presents a new selfcompensation hydrostatic spherical hinge to provide a large load capacity. The hinge consists of an upper part with selfcompensation and a lower part with orifice restrictors. A comparative study of the static behavior is conducted between the selfcompensation hydrostatic spherical hinge and the hydrostatic spherical hinge with orifice restrictors, the result shows that the selfcompensation hydrostatic spherical hinge has an advantage in the static behavior over the hydrostatic spherical hinge with orifice restrictors, including a much larger load capacity, a smaller flow rate, and a smaller power loss.
