The planetary gear set () includes two or more ring gears (), multiple planet gears (), a sun gear (), a first set of teeth (), and a second set of teeth (). One of the ring gears () can be connected to the sprocket () and one of the ring gears () transmits rotational drive output to an engine camshaft.
