Abstract:

Equations for flow rate, pressure, load, and stiffness of externally pressurized thrust and journal bearings are given for purely viscous isothermal gas films with longitudinal and radial flow and no relative surface motion. Charts are presented by means of which the bearing characteristics can be evaluated in terms of the bearing configuration, the ratio of supply to ambient pressure, and a bearing parameter. Sample characteristics of thrust and journal bearings are established using the curves, and experimental confirmation shown. A method of treating bearing films with two inlet-restricting orifices in series is described. Author
