Development of Compliant-Mounted Gas-Bearings for a Small High-Speed, 10KW Turboalternator.

Abstract

Several types of compliant-mounted bearings were developed for application to a Solar 10KW Turboalternator Simulator. The most successful journal bearing incorporated one spring-mounted, pad and two fixed pads, all of which pivoted on a compliant-mount. Component testing of these journal bearings were successfully completed to 76,000 RPM which was the limiting speed of the component rig. Simulator testing was accomplished to 65,000 RPM at which time a journal bearing failure occurred. There is evidence to support the conclusion that the failure was not bearing originated but was due to other factors concerned with the rig. After initial installation difficulties were resolved, the compliant mounted thrust bearings performed very well. The results of the program indicated that the final bearing configurations demonstrated encouraging potential for thier implementation to high-speed turbomachinery. (Author)
