Gas Lubrication Research for 1900 F Non-Isothermal Operation.
Abstract
Experiments were conducted on herringbone-grooved hydrodynamic journal bearings and spiral-grooved hydrodynamic thrust bearings under non-isothermal operating conditions. Journal bearing performance was determined under thermal gradients to 120 F/inch axially, 160 F/inch radially, and 133 F/pi radians circumferentially. Under these conditions, bearing characteristics could be predicted within ten percent using the effective average bearing clearance. A double-acting hydrodynamic thrust bearing was evaluated with thermally induced gradients to 67 F/inch radially, 240 F/inch axially and 60 F pi radians circumferentially. The effective bearing axial clearance after accounting for bearing distortions as determined from statically measured axial end play readings agreed within five percent of the clearance required to predict the measured dynamic characteristics.
