摘要： The invention relates to an eccentric gear arrangement of a motor-driven, hand-guided hedge trimmer (1). The eccentric gear arrangement includes two shearing blades (2, 3) driven in mutually opposite directions over a displacement path (a). Each shearing blade has a connecting link (4, 5) as well as an eccentric wheel (6) having a drive wheel (7) and two eccentrics (8, 9). The eccentric wheel (6) rotates about a rotational axis (10). The two connecting links (4, 5) lie directly above one another. The two eccentrics (8, 9) are arranged on the same side of the drive wheel (7) and engage each in one of the two connecting links (4, 5). The two shearing blades (2, 3) have contact pressure surfaces (11, 12) in the region of their two connecting links (4, 5) and are offset with respect to each other in such a manner that they are exposed at least over a portion of the displacement path (a). Two downholders (13, 14) are provided which act each on one of the assigned contact pressure surfaces (11, 12).

摘要： A hand-guided power tool has a drive motor and a drive element connected to and driven by the drive motor. A working tool is connected to the drive element and driven by the drive element. A braking device is correlated with the drive element, wherein the braking device in a first state, in which the braking device is applied, blocks the drive element and in a second state, in which the braking device is released, releases the drive element so that the drive elements can rotate freely. The braking device has a brake lever and a sensor that detects the first and second states of the braking device. A control unit is provided, wherein an output signal of the sensor as a state signal of the first state or the second state is supplied to the control unit. The control unit, based on the state signal, controls devices of the power tool.

摘要： An electric drive motor for a work apparatus includes a stator having two stator poles which are at a distance from one another in the circumferential direction and have respective field windings. The motor has a rotor which rotates between the stator poles and the rotor shaft of the rotor drives a fan wheel. The cooling-air flow generated by the fan wheel enters the stator, flows therethrough and is discharged therefrom. For effective cooling, a pole intermediate space is provided between the stator poles; and, for the cooling-air flow, this space is filled by a non-magnetic guide body to provide a cooling duct delimited by the guide body and the field windings. The guide body is fastened to a support at one stator end and is inserted axially into the stator at the other end thereof.

摘要： A cuffing chain for cutting mineral and metal materials has central chain links and lateral connecting links. The cutting chain has connecting pins with a central section which has a diameter that is greater than the diameter of openings in adjacent connecting links. The cutting chain has two connecting links which have a supporting section instead of a cutting element. At least two second connecting links positioned adjacent to one another at right angles to the direction of travel of the cutting chain are formed separately from one another. As a result, the cutting chain can be opened for maintenance and repairs despite the use of collar studs as connecting pins.
