<p>The invention relates to an electric camshaft adjuster for adjusting and fixing the phase position of a camshaft of an internal combustion engine in relation to the crankshaft. Said adjuster comprises a three-shaft gear, which is configured as a harmonic drive (19, 19') with a sleeve configuration and a drive gear (1) that is rotationally fixed to the crankshaft, said gear comprising a first rotor wheel (2) and an output part (4) that is fixed to the camshaft and comprises a second rotor wheel (5) that is located next to the first rotor wheel (2). The adjuster also comprises an adjusting shaft (10, 10', 10'', 10''') that can be driven by an electric adjusting motor and a wave generator (17, 17', 17'') with elements for elliptically deforming a flexible elastic sleeve (18) that is provided with external gearing. To improve a harmonic drive with a sleeve configuration, the construction complexity of the harmonic drive (19, 19') is reduced by modifications to the wave generator (17, 17', 17'') and the axis installation space of said drive is reduced by the integration of the rotor wheels (2, 5) into the drive gear (1) and output part (4) which are axially inserted into one another.</p> |
