RESEARCH IN THE FIELD OF LIQUID-METAL-LUBRICATED BEARINGS.
Abstract
The liquid-metal-lubricated program included experiments with a tilting-pad bearing of four-pad design to determine stability and whirl-suppression characteristics in both static and dynamic test rigs. Performance and stability data were obtained for operation in both the laminar and turbulent regimes. Hot and cold water and liquid-potassium lubricant at operating speeds up to 32,000 rpm at temperatures up to 1200 F were used. Results were compared to analytical procedures and were found to be in good agreement. Hybrid bearing tests were conducted using both potassium and water lubricant in the dynamic test rig. Performance of this bearing was determined by stiffness and stability data as well as pressure and flow characteristics. Predicted rotor dynamic performance correlated well with test data. Potassium lubricated tests of thrust bearing were compared with previously obtained water data and with existing analytical results. The correlation of experimental parameters with high-temperature potassium was good, and with room temperature water lubricant fair correlation was obtained. This volume (along with Volumes I and II) include results of all program objectives achieved during this investigation. (Author)
