摘要： An electrically driven linear vibrator has swing drive for vibrating troughs, jarring tables or the like comprises a stator with an exciter winding, an armature guided for linear movement in a direction transverse to the field produced by the stator and a pair of oppositely acting return springs forming together a swing drive, the vibration of which may be used to drive a device connected to the vibrator. The return springs may be constituted by metal springs, gas springs or a combination of both. The swing drive may be constructed as single-acting or double-acting drives. A diode may be connected with the electrical conductors leading to exciter winding so that at a line frequency of 50 Hz, an oscillation frequency of 100 Hz, 50 Hz or 25 Hz may be obtained. The vibrator may also be provided with a piston blower for cooling the windings of the stator.

摘要： An angular attachment to a rotary and percussive power machine, such as a hammer drill, includes a rotary power input tubular member driven by a rotary part of the power machine, a tubular power output supported for rotation at an angle relative to the axis of rotation of the power input member and including a holder for a rotary and percussive work tool. The tubular power input and output members are interconnected by an intermediate power transmission. A device for transmitting impacts from the percussive part of the power machine includes two guiding channels arranged in alignment with central bores of the tubular power input and output members and each enclosing at least one impact deviating element. The impact deviating elements are in sliding engagement with each other and with a corresponding coupling member arranged in respective contact bores of the power input and output members.
