Abstract
A gear assembly having a rotatable housing with an axial end face and a lubrication in-flow opening and a gear set located therein. A lubricant collection ring having an axially extending outer wall is connected to the axial end face. A radially inwardly extending sidewall extends from the axially extending outer wall in a position spaced apart from the axial end face. A lubricant deflector ring is connected to the rotatable housing radially inwardly from the lubricant collection ring. The lubricant deflector ring has a plurality of radially outwardly directed vanes that overlap with the lubricant collection ring. The vanes are configured to fling lubricant against the radially outwardly located lubricant collection ring which directs the lubricant to the at least one lubrication in-flow opening to provide lubricant to the at least one lubricant in-flow opening in the rotatable housing in order to lubricate the gear set located therein.
