Abstract
A safety brake device for braking a machining tool includes at least one brake device configured as an at least two-part claw clutch. The claw clutch includes a first claw-clutch part, and a second claw-clutch part. The first claw-clutch part is arranged on the output shaft so as to allow no relative rotation, the second claw-clutch part is configured to allow no relative rotation with respect to the power tool, each claw-clutch part has a respective plurality of toothing elements, the respective plurality of toothing elements are configured to engage with one another during a braking operation to stop rotation of the output shaft, and a maximum angular spacing Δmax of mutually adjacent toothing elements of at least one of the first plurality of toothing elements an the second plurality of toothing elements is determined depending on a maximum rotational speed of the output shaft.
