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.
A bearing for passage of a lubricating fluid, the bearing comprising at least one opening communicating between an interior of the bearing and an exterior of the bearing, the opening being shaped to increase a pressure of the lubricating fluid as it flows past the opening, such that the bearing acts to urge the lubricating fluid toward the interior of the bearing.
A method for encouraging passage of a lubricating fluid through a bearing, the method comprising:
