Abstract:
A bearing assembly comprises a first bearing axially spaced from a second bearing, each bearing having an inner race disposed on a shaft and having an outer race. The bearings are mounted to a mounting sleeve having an outer sleeve surface and an inner sleeve surface engaging the outer race of each bearing. The mounting sleeve has an outer surface engaged with an inner bearing support of a bearing housing having an enclosed chamber. A housing oil inlet is in fluid communication with the enclosed chamber. The mounting sleeve includes an axially extending sleeve oil passage in fluid communication with the housing oil inlet. The mounting sleeve has a first outlet in the vicinity of the first bearing and the sleeve oil passage has a second outlet in the vicinity of the second bearing.
