    摘要： A switchable gear drive for a handheld power tool has two gears which are to be engaged via an adjustable switching member, the switching member being in a locked position with a retaining ring which is fixedly held on a housing in a first gear and being in an unlocked position with the retaining ring in a second gear. Furthermore, a spindle for accommodating a tool is drivable by an axially spring-loaded gear wheel supported in the housing, the gear wheel being axially supported on the retaining ring on the side diametrically opposed to the switching member. The retaining ring is designed as a circumferential, closed ring.

    摘要： A power drill having percussion drilling function, drilling function and screwing function has a gearing for transmitting the drive motion of a drive unit to a tool spindle. Furthermore, two latching elements are provided which, in the percussion drilling function, are in latching engagement and in the drilling or screwing position are in the disengaged state. A mode setting device has a rotatable supporting ring and a thrust ring, coupled to the supporting ring in a torsionally fixed manner which, in the screwing position is held on the gear housing in an axially displaceable manner.

    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.
