Abstract
The oscillating grinder includes a housing; a drive motor having a rotatably driven armature shaft and mounted in the housing; a grinder plate connected with the housing by one or more supporting members each having a long side; an eccentric element mounted eccentrically on the armature shaft for converting a rotary motion of the motor into a linear motion of the grinder plate; and a transmission element having a long side and connecting the eccentric element to the grinder plate. The transmission element and the supporting members have different angular moments of inertia in different directions so that a displacement of the eccentric element in one direction, advantageously in the handle direction, is completely transmitted to the grinder plate, but a displacement in another direction transverse to the first direction is no more than incompletely, and preferably not at all, transmitted to the grinder plate, thus providing a linear grinding motion.
