Abstract

Analytical solutions of the pressure distribution of externally pressurized concentric journal or parallel surface thust bearings are obtained for compressible and incompressible fluids, for several bearing configurations, by means of complex potential functions. Flow rates, and approximate evaluations of the effects of eccentricity and sliding speed, are also obtained. A bearing design factor for restrictor compensated bearings is presented, and optimum values for maximum bearing stiffness are determined. Comparisons are made between theoretical calculations and available experimental data.
