Abstract
A gear mechanism with a sun gear and a ring gear is provided, where the sun gear and the ring gear are arranged coaxial relative to a gear axis of rotation, and with a transmitter element and an actuating device. The transmitter element comprises a revolving transmitter ring which is arranged eccentric relative to the gear axis of rotation and in sections engages with the sun gear and the ring gear. The actuating device comprises a wobble body, where the revolving transmitter ring is movable by the wobble body eccentrically about the gear axis of rotation in order to move the sun gear and the ring gear relative to each other. A cam phaser for an internal combustion engine having such a gear mechanism is also provided.
