Abstract:
A power tool brake mechanism, in particular a portable power tool brake mechanism, includes at least one mechanical brake unit that has at least one brake element mounted rotatably about a rotation axis and at least one actuating unit that has at least one movably mounted actuating element. The actuating unit is configured to activate and/or deactivate the brake unit. The power tool brake mechanism further includes at least one movement converting unit that has at least one movement converting element configured to convert a movement of the actuating element into a movement of a counter-brake element of the brake unit. The movement of the counter-brake element is at least in a direction that is different from a direction extending along the rotation axis of the brake element.
Abstract:
The invention relates to a rechargeable power supply device for supplying power to an electrical appliance. The rechargeable power supply device is provided with at least one chip on which data for identification of the power supply device can be stored, and can be read by the electrical appliance and/or by a charger.
Abstract:
An auxiliary handle device, in particular for a hand-held power tool, has an auxiliary handle and a damping unit with at least one absorber mass element. The absorber mass element is designed in the shape of a sleeve along a main extension direction of the auxiliary handle device.
Abstract:
An auxiliary handle device, in particular for a hand-held power tool, has an auxiliary handle and a damping unit that includes at least one damping element. The damping element is designed to pivot about a pivot axis while vibrations are being damped.
Abstract:
A hand-held power tool is provided with a housing comprising two separate and interconnected housing parts, one of which is designed as a handle part for holding and guiding the hand-held power tool. At least one housing part is associated with a vibration reduction element designed as a spring element. The vibration reduction element is arranged in an intermediate space between the handle part and the other housing part.
Abstract:
In an electric machine tool with a commutator motor which has a motor shaft which is arranged rotatably in a motor housing and has a commutator, at least two commutator brushes are assigned which are accessible via at least one brush cover provided on the motor housing. A covering element fixes the brush cover on the motor housing in an operating position in which the commutator brushes are covered. The covering element in turn is fastened on the motor housing via a detachable connection.
Abstract:
An auxiliary handle device, in particular for a hand-held power tool, has an auxiliary handle, a fastening unit provided for attachment with the hand-held power tool, and a damping unit with at least one absorber mass element. The absorber mass element is located at least partially on an end region of the auxiliary handle facing the fastening unit along an axial direction between the auxiliary handle and the fastening unit.
Abstract:
An auxiliary handle device, in particular for a hand-held power tool, has an auxiliary handle and a damping unit that includes a counter-oscillation unit with at least one oscillation element. The damping unit includes at least one joint unit, via which the oscillation element is supported in an oscillating manner.
Abstract:
In a hand power tool, including a first housing part and a second housing part as well as a damping element between the first housing part and the second housing part, the damping element is connectable to the first housing part and the second housing part, wherein the first housing part and the second housing part are spaced apart from one another longitudinally of the hand power tool.
Abstract:
A cable kink protection unit, in particular a cable kink protection unit of a portable tool, includes at least one basic body unit. The cable kink protection unit has at least one electric device housing unit integrally connected to the basic body unit.
