ELECTRIC MOTOR TORQUE LIMITING CLUTCH
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 NVH and durability concerns.
Integrated torque limiter/no-back device
An integrated torque limiter/no-back device for use in an actuator with an input shaft, an output, and a gear reduction. The device includes an input ramp, an output ramp coupled to the gear reduction, a combined ramp disposed between the input ramp and the output ramp, a first plurality of balls arranged between the input ramp and the combined ramp, a second plurality of balls arranged between the combined ramp and the output ramp, a pin, and a brake. The pin extends from the input ramp to the combined ramp and coupled to the input shaft. The combined ramp, the output ramp, and the second plurality of balls therebetween are configured to operate as a torque limiter by causing the combined ramp and the output ramp to separate and the output ramp to engage the brake when the torque from the input shaft exceeds a torque threshold.
MECHANICAL CLUTCH DEVICE AND METHOD FOR OPERATING A MECHANICAL CLUTCH DEVICE
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.
Clutch for a winch
A clutch for driving a winch is provided. The clutch comprises an input shaft for connection to a drive means, operatively connected to at least one input friction plate to rotate therewith and an output shaft for driving a winch operatively connected to at least one output friction plate to rotate therewith.
Overload clutch with joint torque and disengagement sensing
An overload clutch comprising an input flange and an output flange, said clutch being configured to transmit torque between the input flange and the output flange and to disengage the clutch when the torque exceeds a predetermined threshold, characterised in, that the clutch comprises one or more sensing means at least partially integrated in at least one of the input and output flanges, and that the one or more sensing means are adapted to jointly determine the torque applied to transmitted between the input flange and the output flange of the clutch and to detect the disengagement of the clutch. A device comprising the clutch, a gear unit connected to the input flange, and a motor connected to the gear unit, configured to provide torque to the input flange through the gear unit.
Damper pulley with leaf spring clutch
A damping pulley assembly is disclosed including a pulley with an outer flange and a fixed pulley plate. A floating pulley clutch plate is located within and engaged with the outer flange. Circumferentially spaced apart leaf springs are connected to a pulley hub. Second ends of the leaf springs are connected to a driven hub that includes a fixed hub plate. Floating clutch plates are located between the fixed pulley plate and the fixed hub plate, which are biased toward the fixed pulley plate by the leaf springs so that the clutch plates contact one another and/or the fixed hub or pulley plates.
INTEGRATED TORQUE LIMITER/NO-BACK DEVICE
An integrated torque limiter/no-back device for use in an actuator with an input shaft, an output, and a gear reduction. The device includes an input ramp, an output ramp coupled to the gear reduction, a combined ramp disposed between the input ramp and the output ramp, a first plurality of balls arranged between the input ramp and the combined ramp, a second plurality of balls arranged between the combined ramp and the output ramp, a pin, and a brake. The pin extends from the input ramp to the combined ramp and coupled to the input shaft. The combined ramp, the output ramp, and the second plurality of balls therebetween are configured to operate as a torque limiter by causing the combined ramp and the output ramp to separate and the output ramp to engage the brake when the torque from the input shaft exceeds a torque threshold.
FLUID DRIVING DEVICE, MOTOR ASSEMBLY AND CENTRIFUGAL FRICTION CLUTCH THEREOF
A centrifugal friction clutch is provided which includes a first friction member to be fixed on a rotary shaft; a support portion to be fixed on the rotary shaft; a centrifugal device disposed on the support portion, the centrifugal device including a cam portion and a centrifugal arm extending the cam portion, the cam portion being rotating relative to the support portion when the centrifugal arm moves; and a friction connecting member disposed between the first friction member and the support portion. When the support portion rotates along with the rotary shaft, a free end of the centrifugal arm moves radially outwardly under a centrifugal force and drives the cam portion to rotate, the cam portion urges the friction connecting member toward the first friction member when the cam portion rotates.
Overload clutch with joint torque and disengagement sensing
An overload clutch comprising an input flange and an output flange, said clutch being configured to transmit torque between the input flange and the output flange and to disengage the clutch when the torque exceeds a predetermined threshold, characterised in, that the clutch comprises one or more sensing means at least partially integrated in at least one of the input and output flanges, and that the one or more sensing means are adapted to jointly determine the torque applied to transmitted between the input flange and the output flange of the clutch and to detect the disengagement of the clutch. A device comprising the clutch, a gear unit connected to the input flange, and a motor connected to the gear unit, configured to provide torque to the input flange through the gear unit.
