| 摘要 |
The present invention relates to an apparatus for adjusting a camshaft of an internal combustion engine with at least one electromotor which produces, by way of a planetary gear, the adjustment of the camshaft with respect to a pinion, with the planetary gear comprising a first ring gear and a second ring gear as well as at least a first planet wheel which is in engagement with the first ring gear and at least a second planet wheel which is in engagement with the second ring gear and which is rigidly connected with the first planet wheel. An efficient position with low adjusting moments is achieved in such a way that several planet sets are provided which each consist of a first planet wheel and a second planet wheel, that the pinion is fixedly connected with the first ring gear, that the camshaft is fixedly connected with the second ring gear, that the first planet wheel and the second planet wheel have a slightly different diameter and that the first planet wheel and the second planet wheel are held on a planet cage which is held concentrically to the axle of the camshaft and the pinion.
