Driving-wheel drives two transmission subsystem. Driving-wheel first drives hub through lower gear, then the middle gear and the upper gear will turn at the same time. Upper gear will drive the back and front wheel hub, so the power will be transferred frome days chasing ring to armillary sphere. The second drive subsystem was powered by the middle gear, because tooth gear was drived by middle gear. The power was passed to the celestial globe and Time-telling System through one pair of Spur gears and one pair of helical gears.
