    Abstract: The present invention is a transmission output shaft that combines a splined or keyed shaft and a yoke or cv-joint into a single unitary shaft. This combination makes for a longer axial length than a separate, individual shaft and yoke arrangement. The simplistic design and unitary construction makes for easy modification of the existing two-part shaft and yoke. The conventional shaft and yoke are removed and replaced with the unitary differential output shaft of the present invention. Various seals and bearing may or may not be used to enhance the overall performance and increase the life span of the jointed area. Due to its simple design and decreased number of parts, the present invention is more cost effective, has a greater reliability and reduces assembly cost because of its ease of installation.

  • Patent number: 6813971
    Abstract: An injection-molded plastic gear 1 as a molded gear includes a plurality of teeth 12 formed around an outer periphery of a rim, and a plurality of blades 8 formed at distances circumferentially on an inner peripheral surface of the rim 11 to produce an axial flow of air. A radially inner portion is formed on the side of inner peripheries of the blades 8 to support the rim 11 through the blades 8. When such injection-molded plastic gear 1 is rotated, the blades 8 produce an axial flow of air passed through holes 10 from the surface side to the back side. The flow of air can be blown to a part such as an IC, a motor and the like disposed adjacent the molded gear to cool it, and the heat of the teeth 12 and the rim 11 can be taken away by a heat transfer, whereby the teeth 12 and the rim 11 can be cooled. Thus, the injection-molded plastic gear 1 has a function as a cooling fan, whereby a forcible convection (flow of air) can be produced in a gear-accommodated space.

  • Publication number: 20040168534
    Abstract: The invention concerns a gearwheel for a mechanical gearwheel transmission of an automotive vehicle, which gearwheel rotates loosely on a shaft, cylindrical rolling elements (18, 19) being arranged between an inner raceway associated to the shaft and an outer raceway associated to a hub of the gearwheel. According to the invention, the gearwheel (13) is mounted through two spaced apart roller crown rings comprising cylindrical rolling elements (18, 19) and cages (20, 25), projections (21, 26) of the cages (20, 25) engaging into a groove (22) that is arranged in a radially inward pointing center flange (24) between the outer raceways (17). In this way, an inseparable pre-assembled unit made up of the gearwheel (13) and the roller crown rings is formed that facilitates the assembly of the mechanical gearwheel transmission.
