A starting protector for an all-terrain vehicle is provided and includes a shaft, a driven wheel fitted over the shaft and comprising a tooth portion, a sleeving portion and a locking portion, and the tooth portion being configured to be connected with an engine; a driving wheel fitted over the sleeving portion, one side of the driving wheel being attached to the tooth portion, and the driving wheel being configured to be connected with a starting motor; a friction piece fitted over the sleeving portion and being in synchronous rotation with the sleeving portion, the friction piece being attached to the other side of the driving wheel, and when starting torque of the engine exceeds a preset value, the driving wheel and the friction piece slipping relatively; and a compressing assembly fitted over the sleeving portion and the locking portion to compress the friction piece and the driving wheel.

Disclosed herein is a joint unit including two facing gears that include respective two bevel gear members that face each other, and an intermediate gear that has a bevel gear member meshing with both the two bevel gear members. One of the two facing gears and the intermediate gear includes a first member including an inner circumferential portion of the bevel gear member of the one of the two facing gears and the intermediate gear; a second member including an outer circumferential portion of the bevel gear member of the one of the two facing gears and the intermediate gear; and a resilient member attached to one of the first member and the second member for normally urging the other of the first member and the second member to move in a direction along the directions of rotation of the one of the two facing gears and the intermediate gear.

A method of adjusting a drive mechanism includes measuring backlashes between the ring gear and the plurality of drive devices, and determining about positions of the plurality of drive devices with reference to the ring gear based on the backlashes measured in the measurement step. The measurement step includes: aligning the pinion of one of the plurality of drive devices to face a reference position in a circumferential direction of the ring gear and measuring a backlash between the ring gear and the said one drive device; and aligning the pinion of another one of the plurality of drive devices to face the reference position of the ring gear by revolving the plurality of the drive devices relative to the ring gear, and measuring a backlash between the ring gear and the said another drive device different from the said one drive device whose backlash has been measured.

The disclosure specifies a gear assembly for an electric-motor assisted steering system, comprising an electric motor, a worm shaft which can be driven by the electric motor and which meshes with a worm wheel. The worm shaft has a recess on an end face which faces the electric motor, in which recess there is arranged an elastic element which applies an axial force to the worm shaft in the direction away from the electric motor. In the axial direction, the elastic element is supported by one end on an adjustment element, which is formed in such a way that it permits expansion of the elastic element in the axial direction when the axial force on the worm shaft exceeds a defined threshold value, and limits expansion of the elastic element when the axial force on the worm shaft lies below the defined threshold value.

A transmission includes an input shaft and an output shaft, the input shaft selectively accepting a torque input from a prime mover, and the output shaft selectively providing torque output to a driveline. A controller determines a shaft displacement angle representing an angle value of rotational displacement difference between at least two shafts of the transmission, and performs a transmission operation responsive to the shaft displacement angle.

A transmission device for lifting a sickbed is fixed on a head mounting or a bed end of the sickbed and contains: a gear seat, a cover, a power input assembly, and a power output assembly. The gear seat includes a first conduit, a second conduit, a first opening, and a receiving orifice. The cover is covered on the first opening of the gear seat. The power input assembly includes an input shaft and a first bevel gear. The power output assembly includes an output shaft, a second bevel gear, and a support element. The support element is rotatably connected with the output shaft. The support element has multiple reinforcement ribs surrounding around an outer wall of the support element and configured to abut against an abutting fence of the second conduit, and the second bevel gear meshes with the first bevel gear.
