A disconnection assembly has a one-way clutch. The one-way clutch serves to either connect or disconnect the power connection of a vehicle. The disconnection assembly is installed in a reducer including an intermediate shaft, a bushing, an outer gear and a one-way clutch. The bushing is secured to the intermediate shaft by spline. The one-way clutch is disposed between the bushing and the outer gear. The one-way clutch is locked to drive the rotation of the intermediate shaft through the bushing when the outer gear rotates in a first direction, and the one-way clutch is released to allow the outer gear rotates freely when the outer gear rotates in a second direction.

A gear-skipping prevention mechanism including a first gear, a second gear, and a positioning member is provided. The first gear is sleeved on an axle. The second gear meshes with the first gear and has a first guiding groove. The positioning member includes at least one body and at least one engaging portion. Each of the at least one body has a sleeving hole. The sleeving hole is sleeved on the axle, and each of the at least one engaging portion is slidably disposed in the first guiding groove to limit a relative position between the first gear and the second gear.

A surgical device adapter for coupling an end effector to a surgical device includes: a proximal joint housing that is couplable to the surgical device; a middle joint housing pivotally coupled to the distal end of the proximal joint housing; and a distal joint housing pivotally coupled to the distal end of the middle joint housing. The middle joint housing is pivotable about a first pivot axis defined between the proximal joint housing and the middle joint housing. The distal joint housing is couplable to the end effector and pivotable about a second pivot axis defined between the middle joint housing and the distal joint housing, the second pivot axis being transverse to the first pivot axis.

A speed reducer-equipped motor of the present disclosure includes a housing to which a motor is fixed and that has a speed reducer housing recess, and a helical gear and a locking gear that are accommodated in the speed reducer housing recess. A spring is provided between the helical gear and the locking gear, and reduces wobbling of the helical gear, the locking gear, and the like in the speed reducer housing recess.

A backdrive braking element is provided for preventing backdrive of a shaft. It includes a poly-lobed locking mechanism including an unlock shaft that has a polygon shaped inside profile and is coupled to a poly lock drive and brake assembly. The poly lock drive and brake assembly includes a plurality of poly lock drive and brake segments and is contained within the interior cavity of a housing.

A hand-wheel actuator for preventing over rotation of a hand-wheel shaft. The hand-wheel actuator comprises a housing that defines an opening aligned about an axis. The hand-wheel shaft extends along and is rotatable about the axis. A drive gear is rotationally coupled to the hand-wheel shaft, wherein the drive gear is at least partially disposed in the opening and includes a drive gear tooth. A stop gear is coupled to the housing and includes a plurality of stop gear teeth for engagement with the drive gear tooth and prevents rotation of the drive gear over a predetermined threshold.
