PLANETARY GEAR CARRIER ASSEMBLY AND RELATED METHOD OF MAKING

摘要

An improved planetary gear carrier assembly is disclosed including a carrier and a ring. The carrier has a hub extending in an axial direction. The hub has splines on a radially-outward facing surface that extend in an axial direction and further has a first set of groove sections on the radially-outward facing surface in which the first set of groove sections extends circumferentially around the hub and through the splines. The ring is received around the hub of the carrier and has splines on a radially-inward facing surface. The splines in the ring are received in the first set of groove sections by axially nesting the splines of the carrier and ring into one another and then angularly rotating the ring relative to the carrier. With the splines of the ring twisted in the groove sections of the carrier, the ring can be axially restricted relative to the carrier.

1. A planetary gear carrier assembly comprising:
a carrier having a hub extending in an axial direction, the hub having a plurality of splines on a radially-outward facing surface of the hub that extend in an axial direction and the hub further having a first set of groove sections on the radially-outward facing surface in which the first set of groove sections extends circumferentially around the hub and through the plurality of splines; a disc lock ring received around the hub of the carrier, the disc lock ring having a plurality of splines on a radially-inward facing surface of the disc lock ring, wherein the plurality of splines in the disc lock ring are received in the first set of groove sections by axially nesting the plurality of splines of the carrier and the disc lock ring into one another and then angularly rotating the disc lock ring relative to the carrier to axially restrict the disc lock ring relative to the carrier; wherein at least one of the carrier and the disc lock ring are a powder metal component.
