Abstract: The invention is based on a handheld power tool having a motor (10), a planetary gear (12) and a tool receptacle (4). It is proposed that the handheld power tool includes an air-moving means (46, 78), located upstream the motor (10), out of sight of the tool receptacle (4), for generating a cooling air stream that cools the planetary gear (12).

Abstract: A slaving and blocking device for transmitting a torque from a driving part to a driven part and for stopping the driven part at a torque engaging the driven part a slaving element fixable on the driving part and having slaving claws offset from one another in a circumferential direction, a roller star wheel connectable to the driven part and having points of a star offset from one another in the circumferential direction, a stationary clamping ring located concentrically with the slaving element and the roller star wheel, wherein a contact face on the points of the star is configured so that the clamping rollers, which when the slaving element is driven are pressed by the slaving claws against contact faces of the points of the star, are thrust inwards, and the slaving faces on the slaving claws are configured such that when the slaving element is driven, they load the clamping rollers with a pressure force such that a tangential force component of the pressure force is substantially greater than a radial fo

Abstract: A hand-held power tool has a motor output shaft, a tool driver, and a torque-limiting unit with which a maximum torque transferred from the motor output shaft to the tool driver is adjustable by an operator, the torque-limiting unit including a spring system, the spring system including differently-acting spring elements.

Abstract: A hand-held power tool has a handle, a least one two-speed transmission, at least one switch element for shifting the transmission between various gear ratios, wherein a distance between the switch element and a gripping region of the handle provided for placement of an operator's hand is less than or equal to a maximum finger extension range.

Abstract: A hand-held power tool has a motor output shaft, a tool driver, a torque-limiting unit with which a maximum torque transferred from the motor output shaft to the tool driver is adjustable by an operator; an actuating element that adjusts the torque-limiting unit, and a retaining element with a spring element, wherein the retaining element holds the adjusting element in a position set by the operator, and a spring element exerts a retaining force directed in an axial direction of the tool driver.

Abstract: A hand power tool has a power tool housing, a tool spindle supported rotatabley in the housing, a drive train via which the tool spindle is drivable to rotate, a cam device located in the drive train and having two cam discs in engagement with one another for transmitting axial percussion motions to the tool spindle, an overlocking coupling located in the drive train and having two coupling parts which are in engagement with one another and are overlockable counter to an axially exerted force, a coupling spring exerting the axial force, a blocking device which upon its activation blocks a relative rotation of the coupling parts of the overlocking coupling to one another, and an operating mode setting device for setting “percussion drilling”, “drilling” and “screw driving” operating modes, and also a magnitude of an overlocking moment upon screwdriving, the operating mode setting device having two adjusting rings located on the power tool housing and rotatable manually to define setting positions and acting on

Abstract: An electric power tool has a plurality of operational component groups; a plurality of separate housings which accommodate the operational component groups, the housings being couplable with one another in series, at least one of the housings being composed of a synthetic plastic casing which is reinforced with a metal sleeve.

Abstract: An electric machining tool includes a plurality of functional components in separate housings (1, 2, 3), whereby the individual housings (1, 2, 3) are coupled to one another and axially aligned. A mounting (5) is provided having a spring-elastic belt (6) that surrounds at least partially coaxially an exterior of one of the housings (1, 2, 3). The belt (6) has a plurality of branching gripping arms (7-12) extending in an axial direction, and the ends (13-18) of the gripping arms are engageable in one or more of the housings (1, 3) adjacent to the housing about which the belt (6) extends. The mounting (5) secures the housings (1, 2, 3) against an opposite movement in the axial direction and rotational movement.
