GAS LUBRICATION RESEARCH FOR 1900 F NON-ISOTHERMAL OPERATION. PART I. BEARING DISTORTION EFFECTS ON PERFORMANCE, AND HIGH TEMPERATURE MATERIAL INVESTIGATIONS.
Abstract
The objective of this program is to develop hydrodynamic and hydrostatic gas lubricated journal and thrust bearings that offer the most promise for non-isothermal operation in air over the ranges: 0 to 90,000 RPM at 80 F to 1400 F Bearing Temperature and 0 to 60,000 RPM at 80 F to 1900 F Bearing Temperature. This report summarizes the anticipated thermal gradients within which gas bearings must operate, the results of experimental evaluations of hydrostatic journal bearing misalignments, out-of-roundness and shaft taper as well as hydrostatic thrust bearing performance under crowning and dishing type distortions. Also included are the results of static and dynamic material and coating tests at temperatures to 1400 F. (Author)
