The invention is based on a power tool with at least one handle () that comprises at least one grip part () that is firmly connected to a mounting part () via at least one elastic, vibration-damping element (), via which the grip part () is affixable to a housing (). It is proposed that the connection between the grip part () and the mounting part () is secured by means of the elastic element () via at least one movable retaining element ().

Hand machine tool comprising at least one handle

A hand power tool has a housing; at least one handle having at least one gripping part; at least one elastic, vibration-damping element; a mounting part mounted on the elastic element; the gripping part being mounted on the housing through the elastic element and through the mounting element; and at least one movable safety element through which the gripping part is connected with the mounting part.

Hand power tool with at least one handle

The invention describes a handle for a hand-held machine tool comprising a grip element () and a fastening element () for fastening the handle to a housing of a hand-held machine tool, wherein the fastening element () partially protrudes into the grip element () and a damping element () is provided between the grip element () and the fastening element (), and wherein the fastening element () forms an undercut () in the grip element ().

Handle for a hand-held power tool

In an armature packet () for an electric motor, having a plurality of armature laminations (), in each of which a plurality of winding slots () for receiving an armature winding () are embodied, and the winding slots () of adjacent armature laminations () are located in alignment with one another and form a conduit (), a better positional fixation of the armature winding () is attained by providing that the winding slots (), associated with one conduit (), of different armature laminations () have different geometries. The same is attained by providing that at least some of the winding slots () each have an influx conduit (), each of which discharges into its region oriented toward the center of the armature packet ().

Laminated armature core for an electric motor

A handheld power tool, in particular a handheld right-angle grinder (), has an electric motor drive for a motor housing () that accommodates a tool and also has a handle (), which is retained on the motor housing () by means of a handle mounting device () located between them, which handle mounting device has a mount (), fastened to the motor housing (), and at least one vibration-damping element () that is in communication with the mount () and the handle (). The handle mounting device () has a mounting plate (), on which the handle () is fastened by means of a fixation device. The at least one vibration-damping element () is located between the mount () and the mounting plate () and is solidly joined to them to form a unitary component. Fastening members () engaging the mount () are provided, which fix the mount () to the motor housing () and are provided with securing elements () that are free-standing relative to the mounting plate () and that, if the vibration-damping element () is torn, firmly retain the mounting plate () along with the handle () mounted on it (FIG.).

An eccentric disk grinder has a grinding disk, an eccentric shaft fixedly connected with the grinding disk, a motor, a shaft having an axis arranged so that the motor eccentrically, circulatingly and rotatably moves around the axis of the shaft, with the eccentric shaft being rotatable relative to the shaft, a braking device provided for delaying movement of the grinding disk and having a braking element which follows the movement of the grinding disk and is delayable relative to the grinding disk.

Eccentric disk grinder with a grinding disk brake

An eccentric disk grinder has a housing, a motor accommodated in the housing and having a shaft provided with an eccentric member, a first bearing supporting the shaft, a grinding disk eccentrically, circulatingly and rotatingly driven by the motor through the shaft, and a second bearing in which the grinding disk is rotatable relative to the shaft about an axis of the eccentric member. The second bearing includes at least one first bearing which takes up substantially radial forces and supports at least one of the shaft and the eccentric member at its end facing the grinding disk. The bearings also have at least another second bearing which takes up substantially axial forces and supports at least one of the shaft and the eccentric member at its side facing away from the grinding disk.
