Performance characteristics of hydrostatic journal bearings with journal rotation by a finite element method

Theoretical studies have been made of a capillary-compensated hydrostatic oil journal bearing supporting a rotating spindle, using a finite element method. Performance data are developed for a four-pocket bearing of $\text{L}\text{D}\text{= 1.0}$. Stiffness and load capacity curves for two significant directions of the line of centres are given for various design parameters and eccentricity ratios. The effects of rotation and the feeding system on the stiffness, load capacity, flow and attitude angle are discussed.
