摘要： A hand power tool has at least one safety coupling arranged in a drive train, the safety coupling having at least two coupling elements for transmitting a torque around a rotary axis, at least one arresting element which is spring loaded and held in a guiding passage for connecting the coupling elements with one another, a guiding element, a spring providing spring-loading of the arresting element and supported in direction of the arresting element by the guiding element, the guiding element being non rotatably guided relative to an axis extending parallel to the rotary axis by guiding surfaces in the guiding passage, and the arresting element unlatching and keeping in contact with a surface toward which the arresting element is urged by the spring in response to exceeding of predetermined torque.

摘要： A device for axially clamping a disc-shaped tool on a flange of a driven spindle with a threaded end, includes a clamping nut, a clamping disc supported on the clamping nut for biasing the disc against the flange and connected with the clamping nut for joint rotation therewith and axial displacement relative thereto, and supporting bodies arranged between the clamping nut and the clamping disc. An actuating member is located between the clamping nut and the clamping disc, and rolling bodies are displaceable along guide paths defined by guide tracks of the supporting bodies and guide track means of the actuating member for radially loading the supporting bodies. An insert member is supported between the clamping nut and the clamping disc and includes a plurality of stops projecting into the guide paths. The actuating member presses the rolling bodies against the stops upon rotation in a first direction corresponding to a clamping direction, and displace the rolling bodies into associated radial recesses thereon upon rotation in a second direction opposite to the first direction to relieve the supporting bodies from radial loads and to relieve the clamping disc from an axial clamping pressure.
