ABSTRACT:
An oscillatory drive comprising a rotating drive shaft is disclosed. The oscillatory drive is driven by an eccentric element that is coupled via a pivot element to a tool drive shaft arranged at an angle to the drive shaft for oscillatingly driving the tool drive shaft pivoting back and forth about its longitudinal axis. The eccentric element comprises a spherical outer ring which is guided within an at least partially cylindrical inner surface of the pivot element. By spring biasing the free end of the pivot element at both outer sides against the housing, efficiency is improved and vibrations are reduced.
