A hand-held power tool is provided which includes a drive unit in a housing, a switch device, and elastomer elements. The drive unit is configured to be switched on and off with the switch device which comprises a switch accommodated inside the housing. The elastomer elements are molded onto the outside of the housing and onto the inside of the housing and are connected to each other via an opening in a wall of the housing. An elastomer element on the inside of the housing forms an elastomer bearing configured to support the switch.

A runoff safety device is configured to prevent runoff of at least one of a chucking element and a tool from a spindle in a braking mode. The runoff safety device has at least one transfer unit and an imbalance compensating unit configured to at least reduce an imbalance of the transfer unit in a mode.
摘要:
A shaft bearing device for a hand-held power tool, in particular for an angle grinder and/or a circular saw, includes at least one first support unit and at least one second support unit which are intended to axially and/or radially support a bearing element of a shaft. At least one of the at least two support units is formed at least partially by a plate element that has at least one axial and/or radial bend.
摘要:
A machine tool with a generator for generating electrical power is disclosed. The generator has a rotor and a stator. A coil and a magnet are arranged on the stator. The rotor is capable of moving relative to the stator and has a first region and a second region. The rotor is configured in such a way that, during a movement of the rotor relative to the stator, a magnetic flux in the coil is changed due to differences between the first and second regions in terms of their magnetic permeability and/or in terms of their geometric configuration, and an electrical voltage is induced.
摘要:
A portable machine tool, in particular a hand machine tool, has at least one spindle for receiving and for driving a processing tool, at least one brake unit for braking the spindle and/or the processing tool at least in a braking mode, and at least one runoff safety unit for preventing the processing tool from running off of the spindle at least in the braking mode.
摘要:
The invention is based on a handheld power tool, in particular a right-angle sander (10), having a gearbox (12), a flange neck (14) with a guard device (20), which device is receivable on the flange neck (14) and forms a receptacle region for a tool (18) and is rotatable in the circumferential direction (22), and having at least one detent device (24) for locking a rotary position of the guard device (20).It is proposed that the detent device (24) is at least partially integrated with the flange neck (14) of the gearbox (12).
摘要:
A power tool, particularly a hand power tool, has a motor housing and a housing cover, in which a brush cover can be removably inserted. Corresponding form-fitting elements are arranged on the motor housing and on the housing cover, said elements being connected to each other in a form-fitting manner in the assembled position. The brush cover is held on the housing cover and/or on the motor housing in a form-fitting manner.
摘要:
A stater of an electrical machine has a cross section, a longitudinal extension, a jacket surface, a plurality of winding holders configured so that at least one of the winding holders for receiving a field winding has a larger winding width than another of the winding holders.
摘要:
The invention relates to a protective hood for a hand tool, in particular for an electrical hand tool which has a support area for the attachment of a flange of the hand tool, and with a clamping device for fastening the protective hood to the flange as well as an anti-twist device to secure the angle position of the protective hood relative to the hand tool. It is provided that the support area (9) has at least one anti-twist device element (18) working in conjunction with at least one anti-twist device mating element (47) of the flange (34).
