A thrust bearing configuration for rotary applications includes a shaft
(12) having an external surface (14) and a housing (16) having an
internal surface (18). The housing and the shaft are adapted for relative
rotational movement. Inner bearing support members (22) extend radially
outwardly from the external surface of the shaft in axially spaced
relation. Outer bearing support members (26) extend radially inwardly
from the internal surface of the housing. A bearing pad (24, 28) is
disposed between each one of the inner bearing support members and an
adjacent one of the outer bearing support members. With the described
configuration an axial force exerted upon the shaft is transmitted from
the shaft through each of the inner bearing support members and bearing
pads to the outer bearing support members and the housing. This thrust
bearing acts like a bearing stack. It is possible to stack any number of
these bearing pads to withstand anticipated axial loads.
