Abstract
An electromotive camshaft adjuster for adjusting the angle of rotation of the camshaft () of an internal combustion engine relative to the crankshaft thereof is provided. The camshaft adjuster includes a triple-shaft gear mechanism, which has a driving wheel (') that is fixed to the crankshaft and is embodied as a sprocket or a synchronous belt wheel, an output part which is fixed to the camshaft, and an adjustment shaft () which is connected in a rotationally fixed manner to a rotor of an electric adjustment motor, having a stator that is fixed on the internal combustion engine. In order to keep the effort for producing the adjusting gears relatively low, the triple-shaft gear mechanism is preferably constructed as a swashplate or single eccentric internal gear drive (), the effort for production thereof being minimized by forming the same in a non-cutting manner, reducing the number of components, and inexpensively adjusting or compensating the backlash.
