Apparent Reduction

The load capacity of tapered-land and pivoted-shoe thrust bearings has been increased significantly by the use of materials with high thermal conductivity and by modified shoe designs. Results of full-scale maximum-capacity tests at 3600 rpm and at 1800 rpm are presented. Improvements in bearing performance have been made possible by an apparent reduction in thermal distortion and bearing temperature.

Results of full-scale maximum load capacity tests on large, 3600-rpm, pivoted-shoe and tapered-land thrust bearings are reported. The results show 700 psi capacity for the pivoted-shoe bearing and 1085 psi for the tapered-land type. Additional evidence of thermal distortion and its effect on thrust-bearing capacity are discussed. A brief description of a new thrust-bearing test installation also is included.

Performance Curves

Self-heating during operation causes a bearing to undergo thermal distortion. A method is presented to determine the consequent effects on the load capacity of a spiral-grooved air-lubricated thrust bearing designed for maximum load capacity. The effect of mode of heat removal is discussed. Appropriate performance curves and a worked example are given.
