Abstract:
1. A device for the relative angular adjustment of a camshaft of an internal combustion engine with respect to a drive wheel ( 6 ) driving the camshaft ( 4 ), comprising an epicyclic gear structure ( 16 ) having a drive-side ring wheel ( 7 ) connected to the drive wheel ( 6 ), a planet wheel ( 8 ) and a central sun wheel ( 9 ), an actuating means ( 12 ) connected to, and driving the central sun wheel ( 9 ), as a function of requirements, and a drive connection from the epicyclic gear structure ( 16 ) to the camshaft, said drive connection being formed by an output-side ring wheel ( 10 ) which is in meshing engagement with the planet wheel ( 8 ) and which has a number of teeth differing from that of the drive-side ring wheel ( 7 ), said output-side ring wheel ( 10 ) being rotatably supported at its circumference in said drive-side ring wheel ( 7 ) centrally around the gear structures and said planet wheels ( 8 ) being disposed, without shaft bearings, axially between a thrust washer ( 23 ) mounted on the ring wheel ( 7 ) and a flange ( 24 ) on the camshaft ( 1 ) for securing the planet wheels ( 8 ) in the axial direction.
