Abstract
A harmonic drive of an electromechanical camshaft adjusters includes a drive wheel designed as a ring gear; an internally toothed output element mounted with radial play in the drive wheel; a further internally toothed element fastened to the drive wheel, the internal toothing of which has a diameter corresponding to the internal toothing of the output element; an adjuster assembly which is formed from a wave generator; an externally toothed flexible gear element which can be deformed by said wave generator, the external toothing of this flexible gear element meshing both with the internal toothing of the output element and with the internal toothing of the further element; an annular gap being formed between the further internally toothed element and an inner peripheral surface of a recess of the drive wheel. The width of the annular gap is at least partially greater than a radial play of the output element.
