Abstract

A harmonic drive, more particularly in an electromechanical camshaft phaser, comprises a drive element (2), a flexible transmission element (26) connected to the drive element (2) and having external teeth (29), and an output element (4) that is designed as a ring gear and has internal teeth (30) that partially mesh with the external teeth (29). The flexible transmission element (26) is pot-shaped, and is coupled in a torque-transmitting manner to the drive element (2) radially inside the outer teeth (29).
