In one embodiment according to the invention, there is disclosed a bearing
for surrounding a rotating shaft. The bearing comprises at least one
external opening communicating with an exterior of the bearing; and at
least one ramped internal cavity, each cavity communicating with one of
the at least one external openings and an interior of the bearing. In
another embodiment, there is disclosed a method for urging a lubricating
fluid into an internal pressure gallery of a rotating shaft. The method
comprises forming a first bearing to surround the rotating shaft, the
first bearing comprising at least one external opening communicating with
an exterior of the first bearing, and at least one ramped internal
cavity, each cavity communicating with one of the at least one external
openings and an interior of the first bearing, such that, in use,
lubricating fluid in the at least one ramped internal cavity is
pressurized as the rotating shaft rotates such that the lubricating fluid
is urged into the internal pressure gallery. Further related embodiments
are also disclosed.
