Embodiment Construction

[0025] The drawing shows an electric hand-held power tool in the form of an angled-handle hand grinder or cutting machine, which is designated as a whole by the reference number 2 . The machine tool comprises a handle part 4 and a transmission housing part 10, wherein the handle part 4 simultaneously forms a motor housing part 6 and is connected to an intermediate housing flange 8 not yet described in detail, the tool spindle 14 is perpendicular to the longitudinal center axis 12 of the machine tool Ground (see FIG. 4 ) extends outwardly from mechanism housing member 10 . A grinding wheel or a cutting tool is fastened on the spindle 14 in a known manner.

[0026] A transmission shaft 18 extends from the electric motor 16 in the direction 12 of the longitudinal center axis through the intermediate housing flange 8 into the transmission housing part 10 . The drive shaft 18 drives the tool spindle 14 via a bevel gear 20 .

[0027] Between the motor housing part 6 and the transm...

Abstract

The electrical hand tool unit, particularly angle grinder or cut-off grinder, has a drive housing (10), a motor housing part (6) and handle part. A counter-brake disc (26) is moved in release direction from a laminar actuating mechanism (36) extending in a level parallel to the level of the counter-brake disc against the spring pre-tensioning and the laminar actuating mechanism is tilted relativeto the earlier level around a certain level.

Description

technical field [0001] The invention relates to an electric hand tool machine, in particular a hand grinder or cutting machine with a curved handle, having a transmission housing part, a motor housing part and a handle part, wherein at least the transmission housing part and the motor housing part are components combined separately from each other , also has a brake device for braking the drive shaft after disconnecting the machine tool, wherein the brake device is disconnected or reconnected by mechanical coupling with a manually operable adjustment member of the machine tool, wherein the brake device comprises A first brake disc connected in a rotationally fixed manner to the drive shaft and a non-rotatable counter brake disc which is spring-biased in the direction of the brake disc. Background technique [0002] Such an electric hand tool is known, for example, from DE 37 41 536 A1. In such power tools, the brake disc, which is connected in a rotationally fixed manner to...
