Dynamic Stiffness and Damping Characteristics of a Sine Film Thrust Bearing

Abstract

The study of dynamic characteristics of a sine film thrust bearing is presented. A dynamic Reynolds equation including the squeezing action is derived. Analytical solutions for the dynamic coefficients are obtained. It is found that the thrust bearing designed with a sine film profile provides better dynamic characteristics than those of the inclined plane bearing, especially for the bearing operating at larger inlet-to-outlet film ratios and smaller outlet film thicknesses.
