Abstract: A rotary drive device includes a housing element, a drive shaft and a driven shaft, both rotatably mounted in the housing element, a transmission device that transmits torque from the drive shaft to the driven shaft, and a braking device configured to counteract rotation of the drive shaft. The braking device includes a drive shaft input element, a braking element connected to the housing element for conjoint rotation, and a coupling element adjustable with respect to the input element. A braking force exerted by the braking device is greater when the coupling element is located in a first position than when located in a second position, and the coupling element assigned to the driven shaft so that adjustment from the first position to the second position is triggered by exceeding a threshold value of the difference in torque between the drive shaft and the driven shaft.

Abstract: An enhanced material-processing device and method are disclosed, having a processing tool of substantially circular circumference, which is operative with a power tool having a rotating spindle and jaws, which clamp the processing tool. The enhanced material-processing device has a central opening that is entered concentrically in the processing tool for receiving a clutch mechanism, and a hub structure. The hub structure is associated with the clutch mechanism to form a slip clutch that is integrally mounted in the enhanced material-processing device and is operative by application of an axial compression friction fit on the processing tool, which slips relative to the rotating spindle when a threshold torque limit is reached. The clutch mechanism is preloaded in axial compression through a predetermined elastic strain distance to provide a friction fit having a torque limit threshold, which torque limit of the slip clutch is controllably pre-adjustable.

Abstract: A coupling device has a pulley that receives rotational torque from an engine. The torque is transmitted to a shaft through a hub and a one-way clutch. A torque limiter is screwed on the shaft to fasten the inner ring of the one-way clutch onto the shaft. The torque limiter has a breakable portion. The torque is directly transmitted from the inner ring to the shaft when the torque is normal. If the torque exceeds the tightening torque of the torque limiter, the inner ring begins to slide and rotate, and drives the torque limiter in a tightening direction. As the torque limiter is tightened additionally, the tensile stress on the breakable portion is increased. Then, the breakable portion breaks and is separated in axial direction so that the coupling device disconnects torque transmission.
