The invention relates to a cable sleeve for guiding a cable in the inlet and outlet region of a hand-held tool. An end of the cable sleeve on the housing side is connected to the housing in a fixable manner, particularly in a form-fitting manner, so that advantageously no dust, dirt, or water may enter between the cable sleeve and the cable. According to the invention the cable sleeve has preferably a radial sealing element which corresponds to the cable and/or the housing in a sealing manner.

Cable sleeve for a hand-held power tool

The invention relates to a machine tool having a two-part housing. The housing parts of the machine tool are connected by a connection device that has at least two connection projections. According to the invention, the connection projections in one housing part are arranged adjacent to each other and engage in corresponding connection recesses, in a positive fit, arranged in the other housing part.

Machine tool, in particular a handheld power tool

An adapter part for a machine tool is designed to be inserted between two housing parts and includes an adapter connection element that corresponds to a housing connection element on a housing part.

Adapter part for a machine tool

The invention relates to a hand-held electric power tool comprising at least one driven rotating part () that is mounted in at least one bearing (). According to the invention, the rotating part () is vibrationally decoupled from the bearing ().

The present invention relates to a brush holder for an electrical machine, including a housing for receiving a brush, a prestressing element, and a securing element disposed on the housing, for securing the brush holder to the electrical machine. The securing element is embodied as essentially T-shaped.

The invention is based on a bearing arrangement for vibratingly supporting a grinding disk () on a grinding apparatus (), in particular in a vibrating grinder, having a plurality of elastic vibration bodies (), which can be connected on the one hand to the grinding disk () and on the other to the grinding apparatus (). It is proposed that the vibration bodies () are disposed, individually or in groups of a plurality of vibration bodies () each, in a plurality of modules () that are separate from one another.

Bearing arrangement for vibrationally mounting a grinding disk in a grinder

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.).

Hand-operated machine-tool comprising a vibration-damping rotary handle

A hand power tool that is driven via an electric motor (), the electric motor () having a commutator () which is formed of disklike annular segments or laminations (), is made more secure against contact spark development by providing that at least one of the laminations () has at least one central recess ().

Protective hood for an angle grinder

The dust removal device comprises a fan (), a dust collection receptacle (), and a suction passage (). The dust collection receptacle () equipped with a dust filter () is located in the path of air flow () between the suction passage () and the fan (). The dust is therefore filtered out of the air stream before it reaches the fan, which prevents dust-induced wear. It is also possible to use the same fan for engine cooling as well as dust removal.

Manually driven machine

A hand grinder, comprising a housing, a motor arranged in the housing, a tool holder with a grinding tool received in the tool holder, a work shaft driven by the motor, two rotary bearings which support the work shaft, a compensating unit arranged on the work shaft for joint rotation therewith between the rotary bearings and provided for compensation of an imbalance produced by the tool holder with the grinding tool during rotation of the work shaft, the compensating unit including different imbalance masses which are offset from one another in an axial direction of the work shaft and are arranged on the work shaft diametrically opposite to one another.

Hand grinder

An impact hammer has a housing, a motor accommodated in the housing, an impacting mechanism accommodated in the housing and having a driver and a striker which is displaced by the driver in an axial direction and periodically strikes a shaft of a tool with the driver being tiltable about a tilting axis, a driving element which drives the driver into a reciprocating motion and a shaft which rotates the driving element. The driving element is provided with two interengaging eccentric parts including a first eccentric part which is non-rotatably connected with the shaft and a second eccentric part which is axially displaceable relative to the shaft. The eccentric parts have ring surfaces each surrounding the shaft, arranged asymmetrically relative to one another and being in contact with one another. The ring surfaces are offset relative to the one another so that a resulting eccentricity of the driving element relative to the shaft, which eccentricity acts on the driver, is adjustable between zero and a maximal value.
