Abstract
An unbalance oscillation generator with constant direction of rotation, in which the resultant centrifugal force is variable due to unbalance on the unbalance shaft including two parts adjustable relative to each other and fixable relative to each other in at least two relative angularly spaced positions. The resultant of the two unbalance forces generated by the two parts varies in value in the individual fixable relative angle positions. A control pin displaceable by means of an adjusting rod extending through the unbalance shaft and projecting from the end face of the unbalance shaft either engages a circumferential groove facing the unbalance shaft but located in the axially non-displaceable part of the unbalance weight or engages a recess or cutout branching off from the circumferential groove. The control pin fits with slight play into the recess and is adapted to be arrested in either one of the respective pertaining axial positions.
