A torque-dependent, releasable clutch for a hand-held power tool is specified, which includes a first clutch element, which interacts with a second clutch element to transmit a torque, at least one of the two clutch elements being movable with respect to the other clutch element and being pretensioned by a spring element, the spring element having a nonlinear load-displacement characteristic.

A mechanical clutch device for coupling two connecting parts in a gas turbo engine, in particular a geared aircraft turbofan engine, with means to automatically trigger a position change of one of the connecting parts relative to the respective other connecting parts and/or relative to an engine part from the first position into a second position in dependence of a torque effective on the connecting parts and/or the engine part, in particular through the transmission via a shaft, in particular a non-nominal torque, more in particular a reversal in the direction of the torque. It also relates to a method for operating a mechanical clutch device.

An electric motor includes a housing and a stator mounted to the housing. A rotor is rotatably supported relative to the stator and a drive shaft is connected to the rotor by a torque limiting clutch disposed within the housing. The electric motor with a torque limiting clutch eliminates high torque episodes due to slippery driving conditions. Also, a torque limiting clutch that features a ball-ramp device with two ramp angles performs the function of a two stage torsional vibration damper. An electric motor can have a specific torque signature that can excite certain vibration modes inside the transmission that can create noise, vibration and harshness (NVH) and durability concerns.

A slip clutch device for an electric driving machine includes a rotation axis, an input side rotatable about the rotation axis, an output side rotatable about the rotation axis, and a slip clutch connecting the input side to the output side in a torque-limiting manner. The slip clutch includes an electrical insulation element for preventing an electrical disruptive discharge line between the input side and the output side, a friction disc, and a friction plate, pressed against the friction disc in a contact region in a frictionally engaged torque-transmitting manner. The friction disc or the friction plate is formed from an electrically insulating material in an insulation region extending radially over the contact region, and the insulation region is a bearing structure for radially transmitting torque.

A novel head device generally consisting of at least one aperture that is capable of excepting different sizes of safety wire, at least one cam-locking lever, which may incorporate a spring return mechanism, is disclosed. The body may be rotated by a mechanical means which twists the safety wire. In preferred embodiment, the various elements of the safety wire twister device are each configured with means of limiting torque or twists of safety wire to eliminate possibility of over torqueing or twisting of safety wire.

A clutch disk for a vehicle may include a hub plate mounted on a shaft to restrict a rotation of the shaft, a sub plate rotatably mounted on the shaft, a presser mounted on the hub plate to restrict a position of the presser and protruding from the hub plate toward the sub plate, and a wave spring positioned between the hub plate and the sub plate, mounted to allow at least a part of the wave spring to adhere to the sub plate, and formed with a flexion to change a spaced distance from the hub plate depending on a rotation direction of the hub plate to thereby change a point and a level pressed by the presser depending on a relative rotation between the hub plate and the sub plate.

A torque limiting tool comprises a two stage torque limiting mechanism that resides within a housing. The torque limiting mechanism comprises a shank positioned through a gear, a plate, and a bias member. The plate is constructed having at least one post and at least one tooth providing a ramp surface that extends outwardly from a plate surface. The gear is constructed having at least one recess providing at least one inclined surface that resides part-way within the thickness of the gear. The gear and plate are positioned in opposition so that the at least one tooth and extending post are received within or detachably mated to the opposing recess and through-bore. Torque is transferred therebetween the plate and gear when the ramped teeth and extending posts mate with the respective recess and through-bore. A first torque limit is exceeded when the post breaks free from the through-bore. A second, lesser torque limit is exceeded when the ramped teeth release from their mated recess.

A dual wheel swivel caster includes a swivel assembly, a horn, a rig hub, a solid axle, at least one ring of roller bearings, first and second wheel assemblies, and at least one ring of bearings. The first wheel assembly has a first wheel axis, and includes an annular plate element. The torque limiter is configured to rotatably couple the first and second wheel assemblies with the solid axle when the torque between the annular plate element and the torque limiter is below a preset value. The torque limiter is configured to rotatably decouple the first wheel assembly from the solid axle and the second wheel assembly when the torque exceeds the preset value. The ring of bearings is configured to allow the first wheel assembly to rotate independently of the solid axle and the second wheel assembly about the rotational axis when the torque exceeds the preset value.
