    摘要: A reduction component is linked to the output shaft of a hydraulic motor, and reduces the rotational speed of the hydraulic motor. A housing component has a rotation-side housing that is rotated around a horizontal rotational axis by the rotation of the hydraulic motor whose speed has been reduced by the reduction component, and a stationary-side housing that rotatably supports the rotation-side housing. The housing component houses the reduction component. A sealing component is disposed inside a gap between the rotation-side housing and the stationary-side housing, and seals the gap. An oil splasher splashes up lubricating oil to provide the lubricating oil to the upper part of the sealing component. The oil splasher has a plurality of concave components formed in the portion of the rotation-side housing facing a seal disposition space in which the sealing component is disposed.

    摘要: Disclosed is a precision rotational transmission mechanism, comprising a fixing support (1), wherein the fixing support (1) is provided with a rotational case (112), which is connected to an electric motor and is provided with a first transmission mechanism (1122), a second transmission mechanism (33) and an output member (10) therein, an end of the first transmission mechanism is connected to motor, the other end is connected to the second transmission mechanism, and the second transmission mechanism drives the rotational case to rotate simultaneously via the output member. The transmission mechanism has a simple and compact structure, has a larger output shaft which has bigger rigidity and can output from two ends has a lighter overall weight which is suitable for industrialization and mass production, has a large transmission ratio, high transmission efficiency, small return difference, strong carrying capacity, strong impact resistance capacity, and long service life.

    摘要: The described reduction gearbox of a gas turbine engine includes a first gear reduction stage having an input gear adapted to be driven by a turbine output shaft. The input gear transfers power received from the turbine output shaft laterally away from the input gear to an input speed gear. Each input speed gear engages an output speed gear to define a main speed reduction gear set, and the main speed reduction gear sets are laterally spaced apart from one another to define a gap. The gearbox has a second gear reduction stage driven by the output speed gears, the second stage adapted to drive an engine output shaft.
