摘要：A device for adjusting the phase angle of a camshaft of an internal combustionengine with a drive gear for driving a camshaft accommodated in a coaxial arrangementrelative to the camshaft and with an electric motor communicating with the camshaft via a

Harmonic Drive having a roller bearing with an elliptical inner ring, an externally toothed,flexible gear arranged on said roller bearing and a rigid, internally toothed gearengaging the externally toothed gear. A simple and compact structure is achieved byproviding the electric motor with a housing which is rigidly connected to the drive gearand which is at least partially arranged therein and by also providing the electric motorwith a rotor configured as a disk rotor accommodated in a slot between two housinghalves of the electric motor.
