An anti-reverse clutch apparatus includes an input shaft, which is rotated by rotation force supplied to the input shaft and which is provided with a push handle, which projects radially therefrom, an output shaft, which is mounted coaxially with the input shaft and is rotatable relative to the input shaft, a clutch housing including an internal gear formed along an internal circumferential surface of the clutch housing, and a locking block, which is mounted between the output shaft and the internal circumferential surface of the clutch housing, and rotatable together with the output shaft and which includes an external gear, which is formed along an external circumferential surface of the locking block to be engaged with the internal gear, the locking block being linearly moved in a radial direction of the output shaft by a sloped surface structure formed between the push handle and the locking block so that the external gear is engaged with or disengaged from the internal gear when the push handle is rotated.

The manual/automatic dual-purpose clutching structure is characterized by including a driving gear assembly, a clutching assembly and a driven mechanical assembly, where the driving gear assembly includes a first gear, a second gear and driving gear driving components, the first gear being coaxially and fixedly connected to the second gear, a gear of the clutching assembly is located on one side of the second gear of the driving gear assembly and meshes with the first gear, the driven mechanical assembly is located on the other side of the driving gear assembly, but does not make contact with the driving gear assembly, and the gear of the clutching assembly rotates around an axis of the first gear of the driving gear assembly under the driving of the driving gear assembly to mesh with the gear of the driven mechanical assembly.

A slip clutch (19) for a hand-held power tool (1) that serves to uncouple a tool socket (2) from a driving motor (5) in the event of an overload is provided. An annular running surface (23) has cams (24) projecting radially inward. The slip clutch (19) has a set of pairs consisting of a preloaded coil spring (28) and a pawl (29). The coil spring (28) presses a head (38) of the pawl (29) in the radial direction outward onto the running surface (23). The pawl (29) has a sheet-metal strip (34) whose one section is bent into a hollow prism that is annularly closed, except for a gap, in order to form the head (38). An insert (35) is placed into the gap (41) so as to fill the gap (41).

Transmission device (100), for example for a watch mechanism (110), in particular for a winding train (100, 201) of a watch movement (120), including an input element (6) intended to be driven only in a first direction, an output element, a first mechanical connection arranged such that the displacement of the input element in a first direction causes the displacement of the output element in a second direction, and a second mechanical connection (9′, 9) arranged such that the displacement of the input element in the first direction causes the displacement of the output element in a third direction, the third direction being opposite the second direction.

A level winding mechanism for a dual-hearing reel is equipped with a worm shaft including intersecting spiral grooves and an engagement pin, and a torque limiting mechanism. The engagement pin engages the spiral grooves. The torque limiting mechanism limits the rotational drive force which rotates the worm shaft. At least a portion of the worm shaft is made of synthetic resin.

A portal gear and a method to implement a portal gear for a model vehicle are provided. The portal gear may include a drive shaft attached to an input gear and an axle attached to an output gear. The portal gear may further include a housing to vertically contain the input gear and the output gear. Wherein the drive shaft transfers a rotational torque from an upper location to a lower location via a gear reduction resulting from the input gear rotating the output gear.

A rotary shifter assembly for changing gears in a vehicle transmission includes a shaft (16) that is rotatably supported in a housing (12) and movable between radial positions for indicating a gear change. A shift knob (10) is coupled to a first end of the shaft for actuation by a user. A plurality of flexible locking fingers (40) extend from the second end, and an overload wheel (18) is disposed about the fingers. The fingers engage the wheel to couple it with the shaft for concurrent rotation. A locking mechanism (64) engages the wheel to selectively prevent and allow concurrent rotation of the wheel and shaft during normal operation. The fingers move relative to the wheel to permit temporary rotation of the shaft relative to the wheel when a force applied to the shaft is beyond a maximum torque threshold, and automatically return to concurrent rotation with the wheel once the force is below the threshold.

A handle includes a torque limiting device. The torque limiting device includes a plurality of driven members and a plurality of driving members. The plurality of driving members is configured to drive the plurality of driven members in a first direction to turn a valve. In response to turning the valve, the plurality of driving members disengages from the plurality of driven members upon reaching a torque threshold. Feedback is provided when the torque limiting device reaches the torque threshold.

An anti-reverse clutch apparatus includes an input shaft provided with a push handle, an output shaft mounted coaxially with the input shaft and rotatable relative to the input shaft, a clutch housing including an internal gear formed along an internal circumferential surface of the clutch housing, and a locking block, which is mounted between the output shaft and the internal circumferential surface of the clutch housing, and rotatable together with the output shaft and which includes an external gear, which is formed along an external circumferential surface of the locking block to be engaged with the internal gear, the locking block being linearly moved in a radial direction of the output shaft by a sloped surface structure formed between the push handle and the locking block so that the external gear is engaged with or disengaged from the internal gear when the push handle is rotated.

A clutch for preventing backdrive, includes a housing: a cover portion positioned on one end portion of the housing; an external shaft, at least one portion of which is positioned inside the housing, the other end portion thereof passing through the housing; a rocker positioned between the housing and the cover portion and fastened to the external shaft; an input shaft, one end portion thereof being inserted into an opening portion in the locker, and the other end portion thereof passing through the cover portion; and a gear portion positioned on the housing or the cover portion so that a serrated portion positioned on the locker is selectively brought into contact with the gear portion, wherein rotation of the rocker is restricted so that the external shaft is rotated along a rotation direction of the input shaft.
