A torque structure includes a first body, a second body, a first elastic member, a third body, and a limit unit. The second body is provided with a second receiving chamber, a first pivot portion, at least one first positioning portion and at least one second positioning portion. The first elastic member is received in the second receiving chamber. The third body is provided with a drive portion, a pivot seat, a second pivot portion, and a first limit portion. The limit unit is assembled with the second body and the third body and rotated between a disengaging position where the third body is unlocked from the second body and has a torque slip function relative to the second body, and a engaging position where the third body is locked by the second body and does not have a torque slip function.

A tooth driven over-torque protection mechanism for use in a slack adjuster or as an air disc brake clutch, includes a shaft, toothed gear, a clutch device, a first spring, and a second spring. The toothed gear is disposed on the shaft. The toothed gear has a first pinion teeth set that extends along a first direction and a second teeth set that extends along a second direction. The clutch device that is also disposed on the shaft and includes an upper cam and a lower cam. The first spring biases the toothed gear against the clutch device. The second spring biases the clutch device against the toothed gear. The upper cam has cam teeth that cooperate with the second teeth set of the toothed gear in a torque transmitting manner, such that a torque applied in a clockwise direction to the first pinion teeth is transmitted to the upper cam through the second teeth set, but torque applied in a counterclockwise direction is opposed by the first spring.

A sealed actuator with internal clutching assembly including an output shaft, output detent ring, moving detent ring, and a wave spring, which is fit inside a sealed housing. The moving detent ring is able to move axially to the output shaft and the output detent ring is able to rotate on the output shaft. Intermeshing ramped teeth of these rings are held together by a wave spring and allow the output shaft to rotate and transmit torque of a motor through a main gear operably coupled to an output gear mounted on the output shaft to the outside of the housing. During predetermined high loads, the output and moving detent rings ramped teeth create an axial force that overcomes the load from the wave spring, which allows moving detent ring to disengage and output shaft to rotate freely to help prevent damage to the actuator.

A slip coupling for a work machine includes a main clutch in the form of a friction-based and spring-operated slip clutch. The slip coupling further includes an auxiliary clutch configured to maintain a pre-set spring-induced clamping force on friction plates of the slip clutch, when the slip coupling rotates in a forward direction, and further configured to be able to increase the spring-induced clamping force, when the slip coupling rotates in a reverse rotational direction. The increase of the clamping force is enabled by the fact that one of two auxiliary clutch parts is axially movable when the slip coupling rotates in the reverse rotational direction, the axial movement actuating an increase in pre-tension of mechanical spring or springs of the slip clutch. A work machine such as a combine harvester equipped with the slip coupling is also described.

A household dishwasher includes a washing container receiving a dishwasher load, a spray arm for applying washing liquor and/or fresh water to the dishwasher load, a drive system for actively driving the spray arm, and an overload protection mechanism configured to move autonomously from a coupling position, in which power is transmitted between the drive system and the spray arm, into a decoupling position, in which the power transmission between the drive system and the spray arm is interrupted, when the spray arm becomes blocked.

A rotational force transmission device includes a transmission mechanism disposed on an input gear, and a ratchet member disposed on an output gear. The transmission mechanism includes a first sleeve having a first interlocker, a second sleeve having a second interlocker that engages with the first interlocker with a rotation clearance in the circumferential direction, and a coil spring disposed between the first and second sleeves. When a drive source is stopped, the second sleeve can idly rotate within the rotation clearance between the first and second interlockers. The first sleeve has a first retainer, and the second sleeve has a second retainer engaging with the first retainer in the axial direction. The first sleeve, the second sleeve, and an urging member are unitized by the engagement of the first and second retainers.

Disposable torque-limiting gearless device with speed reduction. Torque-limiting interfaces having a plurality of undulations arranged around an axial bore or drive socket and separated by a plurality of transition regions configured to engage and disengage to provide torque transmission with predetermined torque limits at various rotational speeds and for amounts of actuations while remaining within a specified operational range. The reduction assembly integral to the gearless torque limiting assembly provides a drive shaft having an input segment, an eccentric segment, and an output segment, wherein the input segment and the output segment each have a centerline running along a same first axis, and wherein the eccentric segment has a center line running along a second axis, the second axis being parallel to the first axis and positioned a first distance away from the first axis.

A torque limiting device includes a shaft member that is rotatable by torque, a first cam portion, a second cam portion and an urging member. The first cam portion is rotatably mounted to the shaft member. The second cam portion is mounted to the shaft member so as to be unitarily rotatable therewith and be movable along an axial direction of the shaft member. The second cam portion is configured to enable torque transmission between the first cam portion and the second cam portion when engaged with the first cam portion so as to be unitarily rotatable therewith. Additionally, the second cam portion is configured to disable torque transmission between the first cam portion and the second cam portion when disengaged and separated away from the first cam portion along the axial direction. The urging member urges the second cam portion toward the first cam portion.

A power tool, in particular a hand-held power tool, preferably embodied as a cordless screwdriver, is equipped with a torque limiting unit in which the release torque is settable by way of a locking brace that is equipped with a spring brace for locking elements that abut axially against parts of a planetary drive, in particular the ring gear thereof or the planet carrier thereof as a last gear stage, the spring elements of the spring brace and the locking elements being located with a radial offset from one another.
