The present invention discloses a transmission device used for expanding monitors, comprising the body, and a combination of at least a first monitor, a second monitor and an actuation module that can be installed thereon. The actuation module can drive the second monitor to move reciprocally on a reference axis X; and the second monitor is provided with a drive module to drive the second monitor to move reciprocally on a reference axis Y perpendicular to the reference axis X, which jointly provide a mechanism, under which an expansion and combination of the screen of the first monitor and the screen of the second monitor (in the same planimetric position) and/or retraction thereof are enabled.

An electric actuator includes a motor, a speed reduction mechanism, a first bearing, and a bearing holder. The speed reduction mechanism has external and internal gears, an output flange that is positioned at one side in an axial direction from the external gear, and a plurality of projecting portions that project in the axial direction from one of the output flange and the external gear toward the other. The plurality of projecting portions are inserted into a plurality of first bore portions disposed along a circumferential direction, respectively. The bearing holder has a cylindrical circumferential wall positioned at an outer side in a radial direction of the first bearing and a support wall supporting the first bearing from the other side in the axial direction. A position adjustment mechanism configured to be capable of moving the support wall in the axial direction is arranged in the bearing holder.

The present invention discloses a transmission device used for expanding monitors, comprising the body, and a combination of at least a first monitor, a second monitor and an actuation module that can be installed thereon. The actuation module can drive the second monitor to move reciprocally on a reference axis X; and the second monitor is provided with a drive module to drive the second monitor to move reciprocally on a reference axis Y perpendicular to the reference axis X, which jointly provide a mechanism, under which an expansion and combination of the screen of the first monitor and the screen of the second monitor (in the same planimetric position) and/or retraction thereof are enabled.

The subject matter of this specification can be embodied in, among other things, an actuator that includes a worm drive assembly having a worm shaft, and a worm wheel configured as a ring having a radially outer perimeter comprising a first collection of gear teeth extending radially outward from the radially outer perimeter and at least partly engaged with the worm shaft, and a coaxial radially inner perimeter comprising a second collection of gear teeth extending radially inward from the inner perimeter, and an epicyclic gear assembly having a sun gear and a planet gear engaged with the sun gear and the second collection of gear teeth.

Disclosed herein is a steer-by-wire type steering actuator. In accordance with one aspect of the present disclosure, a steering actuator may include: a first reducer including a worm configured to rotate by receiving a rotational force of a motor and a worm wheel configured to rotate in engagement with the worm; a pinion shaft coupled to a center of the worm wheel and configured to rotate together with the worm wheel; a second reducer including a first gear formed on the pinion shaft, and an output shaft configured to operate a pitman arm while rotating by receiving a rotational force through a second gear engaged with the first gear; a first gear housing configured to receive the worm and coupled to the motor; a second gear housing provided with a first mounter for receiving and mounting the pinion shaft and a second mounter formed apart to communicate with the first mounter and configured to receive and mount the output shaft, and coupled to the first gear housing; and a holder configured to rotatably support the pinion shaft and having a rotational center axis eccentric with respect to a central axis of the pinion shaft to adjust an axial distance between the pinion shaft and the output shaft.

A folding rotor blade assembly includes a blade fold support and a blade-fold actuator system coupled to the blade fold support. The blade-fold actuator system includes a motor, a tab configured to selectively prevent rotation of a blade tang of a rotor blade, and a cam connected to the blade fold support and coupled to the motor, the cam configured to move the tab between a locked position that prevents rotation of the blade tang and an unlocked position that permits rotation of the blade tang.
