Title: Gear reducer with improved housing configuration

Abstract: A gear reducer housing includes rotating assembly supports in a housing shell, and fixturing pads disposed about the periphery of the housing shell. The fixturing supports are formed in the casting blank from which the housing shell is machined. The pads permit the shell blank to be fixtured once for machining of various features of the final shell. The pads may be formed in a peripheral flange and the flange may be machined around the pads to form a sealing surface. Apertures may be provided in the flange to facilitate assembly of the gear reducer. The apertures and fixturing pads may be provided in mirror image locations about a centerline of the housing. The apertures may be slotted, with major axes of mirror image-located apertures having transverse major axes, such that inherent tolerance is provided for positioning fasteners used to assemble the product.
