摘要： To provide sufficient magnetization to the field of a series motor when the series motor is to be operated in dynamic braking mode, with a dissipating resistor or short circuit element (4) connected across the armature (5), a circuit connection is established between one of the main terminals of the motor through the series field to supply a minimum magnetization current, at least when the motor operates under dynamic braking conditions, typically a few to up to 15% of no-load current of the motor. This is sufficient magnetization so that, even in larger motors where remanent magnetism of the field structure is insufficient, reliable dynamic braking can be ensured. A switch (S; S.sub.1, S.sub.2) selectively connects the motor armature for motor drive or running operation and dynamic braking operation. The magnetization current supply can be through a capacitor, resistor, or resistor-capacitor combination, which can be permanently connected across the power supply (10, 11) of the motor, or connected in circuit only when the switch (S, S.sub.2) changes the motor into dynamic braking operation.

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.

摘要： A safety claw clutch wherein the adjacent end faces of driving and driven rotary clutch elements have alternating claws and recesses and the driven clutch element is biased axially against the driving clutch element by a spring. The bottom surfaces in the recesses of the clutch elements make a first acute angle with a plane which is normal to the common axis of the clutch elements and the front surfaces of claws of the driving clutch element (and hence the rear surfaces of claws of the driven clutch element) make with such plane a second acute angle which is larger than the first acute angle. The top surfaces of the claws are parallel to the respective bottom surfaces. Such configuration of the claws and recesses insures that the force which tends to reengage the clutch elements when the driving clutch element rotates relative to the driven clutch element upon disengagement of the clutch is a small fraction of the force which normally maintains the claws of the driving clutch element in the recesses of the driven clutch element and vice versa because the claws of the driving clutch element cannot enter the recesses of the driven clutch element.

摘要： A handheld machine tool, for example a circular saw, has a disk-shaped tool which is driven in rotation in a housing which holds a drive motor and a tool shaft carrying the tool. The tool can be clamped between a clamping nut, a clamping screw, and two supporting flanges. One supporting flange can be rotated easily relative to the tool shaft without use of auxiliary tools and is supported with an extensive friction at the tool. This supporting flange can be dependably clamped or loosened without tools. The machine tool further has an adjusting device which is coupled with that supporting flange to displace the latter axially toward the tool when that supporting shaft is rotated relative to the tool shaft due to rotational driving. The adjusting device therefore clamps the tool with an increasing force and tries to displace that supporting flange axially away from the tool automatically when the tool is stopped and accordingly reduces the clamping force.
