RESEARCH IN THE FIELD OF LIQUID-METAL-LUBRICATED BEARINGS, PART I,

Abstract

A new general purpose test rig (GPTR) was constructed and checked out. Performance data obtained during a test run of over 700 hours duration were evaluated and the results are presented. Antiwhirl journal bearings of the hybrid type were designed and fabricated. Checkout series in the GPTR using water lubricant were performed preparatory to testing with potassium. The design of a special test rig (system simulation test rig) to be utilized in studying rotordynamic characteristics of typical space power systems with antiwhirl bearings was completed. This rig incorporates three potassium-lubricated test bearings, i.e., two journal bearings, and one thrust bearing. The current endurance test ring was redesigned for thrust bearing performance tests and fabrication is now under way. (Author)
