This application provides a gear shifting mechanism, a gearbox, and a powertrain. The gear shifting mechanism includes a gear, a gear hub, a one-way clutch, and a sliding apparatus. The gear has a first convex wall and a second convex wall that are disposed around a shaft hole. A first toothed structure is disposed at an end of the first convex wall, and a diameter of the second convex wall is less than that of the first convex wall. The gear hub is sleeved on the second convex wall. The one-way clutch is disposed between the gear hub and the second convex wall. The sliding apparatus is sleeved on the gear hub, and the sliding apparatus is capable of sliding in a direction toward or away from the gear. The gear shifting mechanism can improve stability for transmitting a gear shifting power, thereby improving driving performance of an electric vehicle.

Provided is a wind power generation transmission system. A first sun gear is a hollow gear. The first sun gear includes a first end surface and a second end surface opposite to the first end surface. A second planetary carrier includes a third connection end. An outer circumferential surface of the third connection end is provided with external splines. An inner circumferential surface of the first sun gear is provided with internal splines. The third connection end of the second planetary carrier extends from the second end surface to the first end surface and is disposed in the first sun gear so that the external splines of the third connection end are connected to the internal splines of the first sun gear.

A steering reaction force apparatus for a vehicle includes: a housing that is openable and closable by a cover unit, a stator unit fixed to an inside of the housing, a rotor unit disposed to face the stator unit and to be rotated by electromagnetic interaction with the stator unit, a transmission shaft unit connected to the rotor unit to rotate in conjunction with the rotor unit, a power transmission unit disposed inside the rotor unit to transmit a rotational force of the transmission shaft unit to a steering shaft, and a retainer unit to support the power transmission unit with respect to the cover unit.

The present invention relates to a dampened gear system for reducing gear rattle. More specifically, a dampened gear system includes a first gear vibrationally isolated from a second gear. At least one damper prevents rotational engagement between the first gear and second gear until a rotational load is applied. When a rotational load is applied, the at least one damper is compressed, resulting in at least one lug on the second gear contacting an engagement surface on the first gear, allowing the rotational load to be mechanically transferred from one gear to the other gear.

A rotary actuator includes a motor, a speed reducer configured to output after reducing a rotation of a rotary shaft of the motor, and a housing accommodating the motor and the speed reducer. The rotary actuator includes a bearing having an inner ring fixed to the rotary shaft and rotatably supporting the rotary shaft, and a cylindrical outer ring fixing portion integrally provided on the housing so as to fix an outer ring of the bearing. A front housing has a jig insertion hole into which an inner ring receiving jig can be inserted, and the jig insertion hole has an opening that overlaps with at least a part of one end surface of the inner ring in view from an axial direction.

An arrangement including a transmission and a generator is disclosed. The generator includes a generator rotor being non-rotatably connected to an output shaft of the transmission or configured to be connectable to the output shaft of the transmission. An assembly bearing that supports the generator rotor in the output shaft is also disclosed.

There is a demand for further improving efficiency of a task of replacing the reduction gear of the robot. A jig configured to support a reduction gear connecting a first element and a second element of a robot to be enabled to perform a speed reduction operation on each other, when the second element is separated from the first element includes a fixed portion removably mounted to the first element or the second element, a movable portion rotationally or translationally movably mounted to the fixed portion, and a support mounted to the movable portion and configured to suspend and support the reduction gear in a gravity direction.
