Comparison of Predicted and Measured Friction for a Tilt-Pad Thrust Bearing with Crown and Roughness under Hydrodynamic and Mixed Lubrication.

Abstract

In a controlled experiment on a tilt-pad thrust bearing having measured surface crown and longitudinal roughness, the frictional results were compared with results predicted by a physico-mathematical model of the bearing. The bearing operated hydrodynamically using 2190 TEP oil at ambient and 150 F bulk temperature under loads approaching 500 psi.
