Abstract

A drive device for rotating tools operating with oscillation superimposition, including a drive housing, a carrier sleeve mounted rotatably within the drive housing, a drive shaft mounted rotatably therein, a tool carrier to receive working tools and an oscillation-generating mechanism for generating the oscillation superimposition for the one or more tool carriers. The oscillation-generating mechanism for each tool carrier includes at least two intermediate shafts. The intermediate shafts are connected to the one or more tool carriers via an eccentric component part may be driven synchronously.
