摘要： In a handheld power tool having a reduction gear unit, drivable by a motor, for driving a drive shaft, the reduction gear unit being situated in a gear housing and being shiftable via a gearshift at least between a first gear having a comparatively high torque and a second gear having a comparatively low torque, the reduction gear unit is assigned a mechanical overload protection device which is designed to limit the reduction gear unit during operation of the handheld power tool, if a torque, transferred from the drive shaft to the reduction gear unit, exceeds a machine-specific limiting value.

摘要： Disclosed is a machine tool having a spindle driven by a drive device, the spindle having a receiving device on its free end for a tool or a tool holder, an input part being provided in the drive train of the drive device, the input part transferring a torque having a defined play in the direction of rotation via drivers to an output part which is joined in a rotationally fixed manner to the spindle, while a torque acting from the spindle in the direction of the drive device and exceeding a torque on the input side is supported on the housing of the machine tool via clamping surfaces on the periphery of the output part, via clamping elements and via a locking ring having a hollow cylindrical surface. The output part is a driving profile having two or more axially parallel planes, of which a first part acts as clamping surfaces and a second part acts as driving surfaces which cooperate with the drivers of the input part.

摘要： A power tool includes a drive motor and at least one auxiliary device, which is coupled to the drive motor, for activating at least two different operating states. The drive motor and the at least one auxiliary device are controllable using at least one operating device. The output of the drive motor is changed when the at least one auxiliary device is activated. As a result, the operating forces are reduced when switching between operating states, and the load on components is reduced.
