Abstract
The present invention relates to an adjustable camshaft (), which is connected to a crankshaft via a sprocket/belt pulley () and has a phase adjusting device () for adjusting the phase between the camshaft () and the crankshaft. The essential idea of the invention is that the phase adjusting device () comprises a planetary gear () having at least two sun wheels (and) disposed coaxially to each other and planet wheels () surrounding said sun wheels, wherein said planet wheels are rotatably supported on a planet wheel carrier () via a planet wheel axis (). Said planet wheel carrier () can be rotated in relation to the camshaft axis (), wherein a rotation of the planet wheel carrier () brings about a phase adjustment between the camshaft () and the drive.
