Abstract
The disclosure relates to an electromechanical camshaft adjuster comprising an electric motor and an adjusting gear, which has a housing with two housing parts that are sealed off with respect to each other by means of a static seal and with respect to the electric motor and a cylinder head by means of two dynamic seals. A first housing part of the adjusting gear has a pot shape that tapers in a stepped manner towards a housing bottom of the housing part, said pot shape having three different inner diameter regions. In the region closest to the bottom with the smallest inner diameter, a stop plate that acts in the circumferential direction is held. In the region with the middle inner diameter, an output ring gear is mounted with play, and in the region with the largest inner diameter, an input ring gear is secured.
