    摘要： A planetary transmission system is disclosed. In an example, the system may include a planet gear, an outer bearing, and a planetary gear pin including an inner bore fluidly coupled to an outer bore, wherein the outer bore is narrower in diameter than the inner bore and a difference in diameter therebetween allows oil flow by gravity from the inner bore to the outer bore and reduces oil from flow from the inner bore to the outer bore, wherein oil exits the inner bore via a plurality of holes fluidly coupling the inner bore to the outer bearing without valves.

    摘要： A winch includes a power mechanism motor or a hydraulic motor, a transmission, a winding drum, a brake, a machine frame and a sensor. The transmission, the winding drum, the brake, the machine frame and the sensor are arranged in the winding drum. A driving shaft penetrates through a central hole of a central sun gear of each planetary gear. A clutch gear shifter is arranged between each planetary gear stage, the last planetary gear stage and the winding drum. The clutch gear shifter is connected with a power input side planetary gear rack and a power output side central sun gear during neutral gear. The driving unit drives the execution unit tubular member to move to the right side, and the clutch is disconnected from the connection with the left planetary gear. The right driving shaft power output gear is combined with the central sun gear to complete gear shifting. The empty hook or light-load power mechanism directly drives the winding drum to rotate through the driving shaft.

    摘要： A gearwheel arrangement for a transmission of a vehicle, including:



    a gearwheel configured to be rotatable about an axis of rotation (A), the gearwheel including a gearwheel body and an annular gear tooth section extending around the gearwheel body, the gear tooth section including a plurality of external gear teeth, wherein at least a part of the gear tooth section extends past a radially outer portion of the gearwheel body in an axial direction (A) of the gearwheel, so that at least one radially inwardly facing surface is provided opposite of the external gear teeth,
    means for guiding cooling fluid toward the at least one radially inwardly facing surface so as to cool the gear tooth section during rotation of the gearwheel about the axis of rotation.

    摘要： A frictional roller reducer having a sun roller; a ring roller; a plurality of intermediate rollers having rolling surfaces coming in rolling contact with the sun roller and the ring roller; the sun roller or the ring roller having a pair of roller elements including inclined surface portions on a circumferential surface coming in rolling with rolling surfaces, the inclined surface portions inclined in directions going toward the intermediate rollers in a radial direction as going away from each other in the axial direction; a pressing device pressing the pair of roller elements in directions going closer to each other, and an elastic member arranged between the pair of roller elements, the elastic member urging the pair of roller elements in directions going away from the rolling surface of the intermediate rollers.
