ABSTRACT:
Thrust bearing assembly comprising an outer shell (1) and an inner shaft (2) rotatable with respect to each other and having respective inner (3) and outer (4) surfaces defining therebetween an annular space in which is disposed a plurality of rollers, preferably under square, whose arcuate, outer end faces (10) have an overall curvature corresponding to the curvature of the inner surface (3) of the shell (1). In a preferred embodiment, each roller (5') has a bevelled, inner end face such that the rollers (5') form a continuous ring around the shaft (2') with bevels of adjacent rollers (5') in abutment. Also, the inner end face (11, 11') of each roller (5, 5') is preferably tangential to the outer surface (4, 4') of the shaft (2, 2'). The outer end faces (10,10') of the rollers (5,5') provide (i) increased resistance-to-wear characteristics, (ii) reduced scoring of the working surfaces of the shell and shaft, (iii) reduced working temperatures, and (iv) improved internal lubrication.
