Disclosed herein is a bearing assembly comprising: an outer race having an
inner surface; an inner race having an outer surface, the inner surface
of the outer race and the outer surface of the inner race defining a
bearing assembly raceway; a plurality of main rollers positioned within
the bearing assembly raceway, the main rollers in contact with the inner
surface of the outer race and the outer surface of the inner race; a
plurality of mediate rollers positioned within the bearing assembly
raceway counter-rotating with the main rollers such that each of the
mediate rollers is in rolling contact with a pair of the plurality of
main rollers; and a cage positioned in the bearing assembly raceway for
at least partially bounding each of the mediate and main rollers. In one
embodiment, the cage can be positioned within the bearing assembly
raceway and comprises a cage body, the body having a plurality of
parallel annular rims joined by a plurality of rungs, the rungs separated
so as to define a plurality of main roller openings in the cage body for
receiving the plurality of main rollers, the rungs having a plurality of
mediate roller retainers extending from the rungs, the retainers
permitting counter-rotating of the mediate rollers with the main rollers
in the main roller openings. The inventive bearing assembly results in
substantial reduction of noise and vibration when compared to
conventional bearing assemblies.
