摘要： A hand-operated jigsaw is disclosed. The reciprocating drive mechanism has a reciprocating body which can be put into a reciprocating motion along an axis via an eccentric of an eccentric wheel that can be set in motion by the motor. The eccentric wheel is arranged on a pivot bearing axis. The reciprocating drive mechanism has an additional mass with a mass center of gravity to minimize vibrations. The additional mass is arranged in a rotationally fixed manner with the eccentric wheel on the pivot bearing axis. An eccentric axis of the eccentric lies on a first radial of the pivot bearing axis, which is offset from a second radial in the operating direction of rotation of the eccentric wheel at an angle of between 190° and 270°, which second radial lies between the mass center of gravity of the additional mass and the pivot bearing axis.

摘要： A hand machine tool includes a tool retainer that retains a tool, a motor that drives the tool retainer in a rotary motion, and a torque-controlled sliding clutch that is connected in a drivetrain between the motor and the tool retainer. The sliding clutch includes a first clutch disk, a second clutch disk, a spring and a controlling unit which can be activated manually. The second clutch disk is arranged displaceably alongside an axis limited by a stop in the direction toward the first clutch disk. Force is applied to the second clutch disk by the spring alongside the axis in the direction toward the first clutch disk. The manually activated controlling unit variably sets an axial distance between the first clutch disk and the stop, with which an engagement depth of the first clutch disk with the second clutch disk can be defined.

摘要： A method for controlling a motor (2) which drives a disk-shaped tool (4) of a power tool (1) and to which a motor voltage in the amount of a nominal value is applied in an “on” position of a motor switch (6), includes determination of an actual motor current (IM) applied to the motor (2) and comparing it to a first predetermined threshold (GW1), and automatically triggering of a control process for protecting the motor (2) when an overload condition which is defined in that the first predetermined threshold (GW1) is exceeded beyond a first predetermined limiting time period (grDt1), is met, the control process including reduction of the motor voltage applied to the motor (2) by a magnitude that can be perceived by the user as a choke value.

摘要： The invention relates to a device for releasably connecting two coaxially aligned tool parts (1, 2) which can be axially pressed against each other on separating surfaces (36, 38) that face each other with a clamping device. According to the invention, at least one of the separating surfaces (38) is divided into several axially rigid and torsionally soft bearing segments (50) which are spaced in a peripheral direction, in order to dampen the torsional oscillations that occur during the work process and reduce noise.
