Abstract:

A narrow-groove theory for gas on liquid-lubricated herringbone thrust bearings is developed by means of two matched asymptotic expansions. The first expansion, for the film interior, yields a generalized Whipple equation for the average pressure level. The second expansion, for the film edges, yields a generalized Muijdermann-Body pressure correction. Arbitrary transverse groove shape is accommodated by the analysis. The prognosis for development along present lines of a single partial differential equation to include first-order groove-width effects, both in the film interior and at its edges, is very good.
