Abstract: A hand-held power tool including a housing (1) having a handle (7), and a holding device (3) having a catch element (9) and a locking device (11) for releasably securing the catch element (9) to the tool housing (1), with the catch element (g) being secured to the housing (1) in a plane passing through a pivot point (S) and extending parallel to the machine plane defined by the plane of the handle (7) and the operational direction (H) of the tool.

Abstract: A screw driving tool comprises a housing (1), a drive (2), a drive spindle (3), a torque coupling (4) between the drive (2) and the drive spindle (3), as well as an adjustment mechanism disposed between the free end of the drive spindle (3) and the torque coupling (4), the adjustment mechanism is used for adjusting the torque transmitted using the torque coupling (4). The adjustment mechanism has at least one prestressable spring element (5) cooperating with the torque coupling; a compression sleeve (6) that is displaceable parallel to the axis of the drive spindle (3) and cooperating with the spring element (5); a control sleeve (7) arranged coaxially with the compression sleeve (6) and cooperating with the compression sleeve (6); a rotatable adjustment sleeve (8), and a plurality of rotationally mounted planet wheels (10) cooperating in a form locked manner with the control sleeve (7) and inner teeth (9) of the adjustment sleeve (8).

Abstract: Torque fluctuations, which, on one hand, come from the engine, and on the other hand, come from the power take-off side due to the effect of the rudder and beating of the blade, and which are primarily caused by the typically low rotational speed in drives of watercraft, lead to intense vibrations in the hull and generate. noise. A device for transmitting torque in the power train of a watercraft damps torsional vibrations occurring in the power train of a watercraft and, therefore, ensures low-noise and low-vibration operation. The device includes an engine-side, primary flywheel mass, a secondary flywheel mass coupled at the power take-off to a gearbox driving the ship propeller, as well as a torsionally elastic connection disposed therebetween.

Abstract: A screw driving tool including a housing (1), a hollow spindle (3) rotatably supported in the housing (1) with a possibility of a limited axial displacement relative thereto, a screw-in spindle 5 at least partially extending in the hollow cylinder (3), connected thereto for joint rotation therewith, and supported for a limited axial displacement relative thereto, an impact mass (15) for displacing the screw-in-spindle (5) in a screw-in direction, a drive motor (2) for rotating the screw-in spindle (5), and a clutch (6) located between the hollow spindle (3) and the drive motor output shaft (19) for transmitting rotational movement to the hollow spindle (3).

Abstract: The apparatus for tightening or installing a screw connection includes a screwdriver device (20) having a drive motor (20a) and a screwdriver spindle (20b); a control device (30) for controlling a torque, rotation speed, rotation angle, rotation direction, advance and/or tightening time of the screwdriver spindle (20b) and an operating device (40) including an input and/or output device (40a) for selecting a predetermined tightening or screwing process program which is assembled in a modular manner from individual tightening or screwing process program steps and which is used by the control device (30) to control the screwdriver device. The input and/or output device (40a) includes a device for providing an input display (40b) having a multi-dimensional, advantageously two-dimensional, field (40c) with a plurality of predetermined distinct field locations (40d) and a device for associating the respective field locations with predetermined tightening or screwing process program steps.
