A drive device for an actuator for a brake device of a motor vehicle. The drive device has an electric machine having a rotor rotatably mounted in a housing and a stator fixed to the housing. A bearing shield is situated in the housing that has an axially extending sleeve-shaped bearing segment for the rotatable bearing of a drive shaft, which bears the rotor. The bearing shield has an axially extending sleeve-shaped retaining segment held with a frictional fit in a sleeve-shaped end segment of the housing and has a diameter that is greater than the diameter of the bearing segment. A radially extending annular disk-shaped floor segment of the bearing shield is between the retaining segment and the bearing segment. The retaining segment has a first axial partial segment connected to the floor segment, and a second partial segment connected to the first partial segment.

A handheld work apparatus includes a work tool, a belt drive, a drive motor configured to drive the work tool via the belt drive, a brake unit configured to act on the belt drive, and a holding arrangement. The brake unit has a braking position and a released position and the holding arrangement is configured to hold the brake unit in the released position. The holding arrangement includes an electromagnet to which current is supplied during operation of the work apparatus.

A guide assembly for a disc brake, the guide assembly comprising a bore disposed in a disc brake caliper for receiving a guide pin. The bore comprises a first bore portion with a substantially circular cross-sectional profile and a second bore portion with a substantially circular cross-sectional profile arranged sequentially along the length of the bore and tangentially offset such that the bore is defined by the overlap of the first bore portion and second bore portion and has a lens-shaped cross-sectional profile.

A salad spinner has a hub connected in a rotary driving relationship to a colander mounted within the salad spinner for rotation about an axis of rotation. A brake provides braking force to the hub coaxially with the colander axis of rotation. The brake includes a spring-loaded button located coaxially with the colander axis of rotation and an actuation element between the button and the hub for applying coaxial, linear force from the button to the hub for braking. A drive plate is connected in a rotary driving relationship to the hub, and the button is constrained for co-rotation with the drive plate and linear motion relative the drive plate.

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.
