| Abstract: | Externally pressurized gas-lubricated bearings with multiple orifice feed are investigated. An analytical treatment is developed for a semicylindrical bearing with 9 orifices and for a cylindrical journal bearing with 192 radial and 24 axial orifices. Experiments are described on models of the two bearing configurations with specially designed fixtures which incorporate pneumatic loading and means for determining pressure profiles, gas flow, and gap height. The correlation between theory and experiment is satisfactory. |
