Bearing system

摘要

A bearing system includes an inner ring that surrounds an axis of rotation, an outer ring spaced radially outwards from the inner ring, and a cage that is positioned between the inner and outer rings to support a plurality of bearing elements. The inner ring includes an axial slot that extends in a direction along the axis of rotation. The inner ring also includes at least one radial side slot formed in at least one of a fore and aft end surface of the inner ring. The radial side slot directs lubricating fluid from the axial slot toward the cage to lubricate the plurality of bearing elements.

1. A bearing system comprising:
an inner ring having an inner circumferential surface surrounding an axis of rotation, an outer circumferential surface spaced radially outwardly from said inner circumferential surface, a fore end surface extending from said inner circumferential surface to said outer circumferential surface, and an aft end surface axially spaced from said fore end surface and extending from said inner circumferential surface to said outer circumferential surface; an outer ring spaced radially outwardly of said inner ring; a plurality of bearing elements supported by a cage positioned between said inner ring and said outer ring; wherein said inner ring includes at least one inner slot extending generally in an axial direction along said axis of rotation and wherein at least one of said aft end surface and said fore end surface includes at least one side slot extending from said at least one inner slot toward said cage such that lubricating fluid is directed to said plurality of bearing elements by said at least one inner slot and said at least one side slot; and an annulus formed at an intersection between said at least one inner slot and said at least one side slot to collect and supply lubricating fluid for distribution to said at least one side slot, and wherein said annulus is defined by a tapered surface that transitions from said inner circumferential surface of said inner ring to one of said fore and said aft end surfaces.
