A mechanism for transmitting rotational motion from a drive shaft such as a crankshaft of an engine to one or more parallel shafts such as camshafts comprising a triangular link connected to the crankshaft by an eccentric crank and connected to the camshafts by internal gears which engage with sprockets connected to the camshafts. The gear ratio between the crankshaft and camshafts is determined by the radii of the internal gears and the sprockets. The link can also be used to drive auxiliary components such as an alternator or a water pump, or to transmit drive from a starter motor to the crankshaft when the engine is started. |
