Abstract

Purpose

This paper aims to provide a new method for fast calculation of the recess pressure for hydrostatic bearing compensated by orifice restrictor.

Design/methodology/approach

Three methods (new method, old method and finite difference method) are used to calculate recess pressure for hydrostatic bearing at different eccentricity ratios and radial clearances, and the results with the three methods are compared.

Findings

From the results, the conclusion is that the new method has a simple calculation process and a quick calculation speed.

Originality/value

The new method can be used to calculate the recess pressure of hydrostatic bearing with high precision and simple computing process.
