    摘要： A torque transmission device connects two rotary shafts having shaft ends opposing each other, such that torque is transmitted through a torque transmission mechanism provided to a shaft end surface of each of the two rotary shafts. A first rotary shaft of the two rotary shafts has a double-supported structure where both end portions of the first rotary shaft are supported by bearings, respectively. A second rotary shaft of the two rotary shafts has a cantilever structure where only one end portion of the second rotary shaft opposite to the torque transmission mechanism is supported by a bearing, and the second rotary shaft is spaced from one bearing of the bearings supporting the first rotary shaft, the one bearing being provided at a side of the torque transmission mechanism.

    摘要： A constant-velocity drive system for an aircraft rotor has a gimbal mechanism and a differential torque-combining mechanism. The gimbal mechanism has gimbals driven in rotation by a rotor mast about a mast axis, the gimbals providing for gimballing relative to the mast about gimbal axes generally perpendicular to the mast axis. The differential torque-combining mechanism is connected to the gimbal mechanism and configured to be driven in rotation about the mast axis by the gimbal mechanism. The differential mechanism is capable of gimballing relative to the mast about the gimbal axes, the differential torque-combining mechanism having an output component attached to a yoke of the rotor for driving the yoke in rotation with the differential torque-combining mechanism.

    摘要： A uniform speed joint has three or more drive pins one side ends of which are concentrically arranged in one side face of either one of a driving member and driven member, and the other ends of the drive pins are rotatably and slidably arranged in one side face of the other member and supported through ball bearings the periphery of which is restricted and supported. An axial piston pump is constructed by application of the uniform speed joint.

    摘要： A torque converter assembly including means for reducing the axial thrust loading transmitted to the crankshaft by which the torque converter is driven and to thereby reduce thrust wear of the crankshaft bearing. This means includes a thrust washer loosely retained in the turbine hub of the torque converter and a shaft bolt securing the thrust washer and turbine hub to the end of a transmission input shaft driven by the torque converter. Also, the torque converter is coupled to the engine flywheel by a plug-in mounting comprising a plurality of drive lugs secured to the torque converter housing and received in aligned bores formed in the face of the flywheel.
