  • Patent number: 10471530
    Abstract: A brazed part includes two or more components that are brazed together and has related method of making. Using a method of locating parts relative to one another, an inter-component gap between the components may be formed. Subsequently, during brazing, flow control features formed along the inter-component gap may then be used to assist in the retention of the braze material between the components during brazing.

  • Patent number: 10161503
    Abstract: A planetary gear carrier has a drum cover and drum hub that make up a drum of the carrier and a carrier plate spaced from the drum cover defining a space in which the planetary gears reside, The drum cover, drum hub and carrier plate are joined by keys that are formed integrally with at least one of them that mate with surfaces of the other parts for precise assembly and re-assembly, and windows are defined through sets of spline teeth of the dram cover and drum hub through which planetary gears may be inserted for assembly to the carrier while the drum cover, drum hub and carrier plate are assembled to one another.

  • Patent number: 10151382
    Abstract: 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.

  • Publication number: 20160258527
    Abstract: A sintered powder metal part and a related method of making the part are disclosed. The sintered powder metal part, which is formed from a compacted and sintered powder metal, includes a hub having a radially-outwardly facing surface and a radially-inward facing surface. A toothed profile is formed in one of the radially-outwardly and radially-inward facing surfaces of the hub. One or more grooves are machined into the other of the surfaces of the hub such that the toothed profile and the one or more grooves are on oppositely-facing radial sides of the hub. The groove or grooves intersect with at least some of the tooth roots of the toothed profile to form a plurality of radially-extending spaced openings through the hub.
