PRESS FIT KEYED OUTER RACE IN STATOR

摘要

The invention presented is an outer race for a stator assembly which includes keys that extend radially outward from the outer circumferential edge. The keys include transverse projecting splines. The splines are configured to cut grooves into the body of a stator to form a press fit connection between the outer race and the stator. The connection reduces or eliminates a loosening of the stator-outer race connection when fluid temperatures increase as well as reducing the effects of lash by reducing or eliminating gaps in the stator-outer race connection.

1. An outer race for a stator assembly comprising:
a body; an outer circumferential edge; a plurality of keys extending radially outward from said outer circumferential edge, each of said plurality of keys having a thickness, a pair of opposing sides, and an outer key edge extending between each one of said pair of opposing sides; at least one spline projecting from at least one of said two opposing sides; and, an inner circumferential edge.
