Abstract
An oil deflector includes a segment array extending radially from a sleeve portion defining a longitudinal axis and configured for mounting on a shaft. The segment array includes a plurality of segments arranged circumferentially relative to the longitudinal axis and defines at least one oil diverting feature configured to create a pressure differential proximate the segment array or across a surface of the segment array during rotation of the oil deflector about the longitudinal axis. The segment array may define an oil diverting feature configured as a radially tapered peripheral surface, an axially inclined annular surface, at least one slot inclined relative to an annular surface of the array, and/or a combination of these configured to divert oil axially and/or radially from the oil deflector during rotation by the shaft in use.
