    Abstract: A composite transmission housing is provided with a die-cast metal base and an over-molded plastic body. The metal base provides mechanical strength for the transmission gears, while the plastic body forms a leak-free oil pan for the transmission oil. The method of making the composite transmission housing includes the steps of die-casting the metal base, inserting the base into a mold, and over-molding the plastic body onto the base.

    Abstract: A driving device includes a motor, and a gear housing secured to the motor. The gear housing accommodates reduction gears. Rotation of the motor is reduced by the reduction gears before being transmitted to an output shaft supported by the gear housing. A support cylinder extends from an outer surface of the gear housing to support the output shaft. A surrounding cylinder extends from the outer surface of the gear housing to surround the support cylinder. Reinforcing ribs are located between the support cylinder and the surrounding cylinder. Each reinforcing rib extends from a circumferential wall of the support cylinder such that the angle between the reinforcing rib and a normal line that intersects the circumferential wall form a predetermined angle. Each reinforcing rib has a radially inward end connected to the support cylinder and a radially outward end connected to the surrounding cylinder.

    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.
