The disclosure relates to a hand-held machine tool comprising a tool receptacle and a housing, in which a drive motor having a motor shaft and a transmission are arranged. The transmission is arranged in a transmission housing, and wherein a spacer element is arranged between the transmission and the drive motor, which spacer element comprises a disc-shaped base body on which a tubular mounting portion is formed for mounting on the motor shaft, said spacer element forming a seal, in particular a labyrinth seal.

Hand-held machine tool comprising a spacer element

A hand-held power tool includes a drive unit actuatable via at least one manual switch, a control unit at least for controlling the drive unit, the control unit having a control-unit housing. The power tool further includes at least one user interface having at least one operating element, and a housing that at least partially accommodates the control unit and the user interface. The hand-held power tool also includes a positioning device, the user interface being supported on the control-unit housing by use of the positioning device.

Hand-held power tool

The disclosure relates to a method for operating a handheld power tool having an electric motor, the method comprising: Sproviding at least one model signal waveform that is associated with a work progress of the handheld power tool; Sdetermining a signal of an operating variable of the electric motor; Scomparing the signal of the operating variable with the model signal waveform and determining a conformity evaluation on the basis thereof; Sidentifying the work progress at least partially using the conformity evaluation; Sexecuting a first routine of the handheld power tool at least partially on the basis of the work progress identified in method step S. The disclosure also relates to a handheld power tool, in particular an impact driver, comprising an electric motor and a control unit, wherein the control unit is designed to carry out a method according to the disclosure.

Method for operating a handheld power tool

A hand-held power-tool device is described as including at least one intermediate shaft, which is formed as a planet wheel carrier and includes a plurality of planet wheel receptacles and planet wheel bearing points situated in the circumferential direction. It is provided that the intermediate shaft includes at least one material recess at least in the area of at least one planet wheel bearing point on its outer circumference.

Hand-held power-tool device

A handheld power-tool device is described as including a drive unit, which includes at least one driveshaft, and at least one rotary striking mechanism, which includes at least one intermediate shaft aligned at least essentially flush with respect to the driveshaft, and at least one bearing for mounting the driveshaft. It is provided that the bearing is situated at least partially in a plane, which intersects the intermediate shaft and extends at least essentially perpendicularly with respect to the intermediate shaft.

A hand-held power-tool device including at least one drive housing, at least one striking mechanism housing, and at least one rotary striking mechanism, which includes at least one planetary gear including at least one annulus gear. It is provided that the annulus gear is clamped between the drive housing and the striking mechanism housing.

A machine tool system includes at least one portable machine tool and at least one energy storage apparatus. The at least one portable machine tool includes at least one tool receptacle configured to be arrange a machining tool, and at least one receiving interface. The at least one energy storage apparatus is configured to be arranged on the at least one receiving interface of the at least one portable machine tool. At least in a state when the at least one energy storage apparatus is arranged on the at least one receiving interface, the at least one energy storage apparatus is arranged at least for the most part within a boundary region of the at least one tool receptacle.

Machine tool system

In a tool attachment for a handheld power tool, which includes a tool housing having a fastening interface, having an attachment housing, on which a locking unit, for locking the tool attachment on the fastening interface of the handheld power tool, and a tool receptacle for accommodating an insert tool are situated, a percussion mechanism is situated in the attachment housing, which is configured to apply percussions carried out in the axial direction in relation to the tool receptacle to an insert tool, which is situated in the tool receptacle, during percussion operation of the tool attachment, the tool receptacle being fixed in position in the attachment housing in a non-rotating way at least during percussion operation.

Tool attachment for a handheld power tool

A handheld machine tool, in particular a battery-driven handheld machine tool, having a gear unit and a cooling air unit. The cooling air unit is provided to route a flow of cooling air for cooling the gear unit past at least one gear element of the gear unit.

Handheld machine tool

In a handheld machine tool having a tool housing, in which a drive motor is situated for driving a drive element equipped with at least one clamping surface, to which a spindle-locking device equipped with a blocking element and at least one spindle cylinder is assigned, the at least one spindle cylinder being able to be clamped in a spindle-lock operation of the spindle-locking device between the at least one clamping surface and the blocking element in order to prevent the drive element from rotating relative to the tool housing, the spindle-locking device has an impingement element, which is developed to impinge on the at least one spindle cylinder with a specified force in the direction of the at least one clamping surface.

Handheld machine tool having a spindle-locking device

A tool attachment for a handheld power tool that has a housing having a fastening interface includes: an attachment housing on which there is situated a locking unit for locking the tool attachment on the fastening interface of the handheld power tool; a tool receptacle for accommodating an insertion tool; and a hammer mechanism situated in the attachment housing, which hammer mechanism is configured to apply an impact in the axial direction of the tool receptacle on the insertion tool, during hammer operation of the tool attachment.

Tool attachment for a hand-held power tool

A tool system having a hand-held machine tool including a tool holder for receiving an insert tool; and a mounting interface configured for mounting thereon: an angle attachment that includes an angle locking section for locking on the mounting interface and an angle drive unit; and an eccentric attachment that includes an eccentric locking section for locking on the mounting interface and an eccentric drive unit.

Tool attachment for a hand-held machine tool

A hand tool device includes: a striking mechanism which has a striker, a striker driving device, and a striker arresting device. In the case of a first drill rotation direction, the striker driving device is configured to propel the striker in at least a striking direction. The striker arresting device is configured to prevent the striker driving device from being operated in the case of a second drill rotation direction.

Hand tool device

The invention is based on a hand-held power tool device equipped with a locking device. The locking device is provided for locking an output device and has at least one locking element for supporting at least one radial clamping force. According to a proposed embodiment, the locking element is provided to fasten and/or axially secure at least one component.
