Abstract

An oscillation drive with a drive and with an eccentric coupling drive for converting a rotary motion of the drive into an oscillating rotary motion of a tool spindle about its longitudinal axis is disclosed, wherein the eccentric coupling drive has an eccentric with a first eccentricity that is driven by the drive and that works together with a coupling element that is coupled to the tool spindle in order to convert the motion of the eccentric into an oscillating rotary motion of the tool spindle, wherein the eccentric is coupled to an additional eccentric with a second eccentricity so that the eccentricities are superimposed, wherein the relative position between the eccentric and the additional eccentric is adjustable to at least two different positions in order to change the amplitude of the oscillating motions of the tool spindle.
