Abstract
A device for phase-shifting a rotational angle of a drive wheel relative to an output shaft. The device includes a planetary gear including a sun wheel, a hollow wheel and at least one planet wheel, wherein the sun wheel and the hollow wheel mesh with the at least one planet wheel. A planet wheel carrier having the at least one planet wheel is arranged thereon and is fixedly connected to the output shaft so as to commonly rotate with the output shaft. A drive wheel is connected to the planetary gear and is at least indirectly connected to the sun wheel. An actuator engages the planetary gear so that the hollow wheel is rotatable relative to the sun wheel. The actuator is disposed tangentially to the planetary gear and includes a worm engaging an outer toothing of the hollow wheel, with the sun wheel being at least indirectly connected to the drive wheel.
