  • Publication number: 20240293923
    Abstract: A power tool, wherein a lubricant for gearbox lubrication can be accommodated in a gearbox housing interior of the gearbox housing, wherein the output shaft has a first end on which an insert tool unit can be mounted, and has a second end, wherein the output shaft is designed as a hollow spindle with a cavity. A hollow cylinder section is formed at its second end. An actuator is arranged in a rotationally resistant manner to the gearbox housing, which engages with the hollow cylinder section. Between the hollow cylinder section and the actuator, a gap extends along the axis of rotation which at its first end is connected to the cavity and at its second end to the gearbox housing interior. A shaft seal is disposed in the gap, which counteracts the leakage of lubricant from the gap towards the first end of the output shaft.

  • Publication number: 20230286059
    Abstract: The invention relates to a tool device which is suitable for use with a machine tool, in particular a hand guided machine tool, having a driving device moving, in particular in an oscillating manner, around a driving axis. The tool device has an attachment device which allows it to be fastened on a machine tool such that its driving axis and an axis of rotation of the tool substantially coincide. The attachment device, for absorbing the driving force, has at least two driving area regions, which are spaced apart from said tool axis of rotation and each has a plurality of surface points. The tangent planes to said surface-area points are inclined in regard to an axial plane, which encloses the tool axis of rotation. Furthermore, said tangent planes are inclined regard to a radial plane which extends perpendicularly to the tool axis of rotation. This means that the torque introduced into the tool device by the machine tool, via the driving device, is reliably absorbed.

  • Publication number: 20210220923
    Abstract: The invention relates to a machine tool, in particular a hand held machine tool, which has a tool receiving device that is movable, in particular in an oscillating manner, around an output shaft. The tool receiving device is designed to hold a tool device on the machine tool in such a manner that the output shaft and a tool rotation axis substantially coincide. The tool receiving device has at least one torque transmission region and a holding device. In order to transmit a driving force to the tool device, the torque transmission region has at least two output area regions that are arranged at a distance from said output shaft and each have a multiplicity of surface points. Here, the tangent planes to said surface points are inclined in regard to an axial plane which includes said output shaft. Furthermore, the tangent planes are inclined in regard to a radial plane which extends perpendicularly to the output shaft.

  • Patent number: 10471518
    Abstract: The invention relates to a machine tool, in particular a hand held machine tool, which has a tool-accommodating device which can be moved, in particular in oscillating fashion, about a drive axis, in order to retain a tool device on the machine tool. The tool-accommodating device has at least one clamping device, at least one retaining device and at least one locking device. The retaining device can be moved from at least one first, open position into at least one second, closed position. It is also the case that the retaining device can be forced by a clamping force, by way of the clamping device, preferably in the closing direction from said first, open position in the direction of said second, closed position. The locking device can be moved between at least one first, locking position and at least one second, unlocking position. It is possible here for said locking device to block movement of the retaining device in at least one locking position.
