The invention provides an inner gear ring power transmission system of a multi-rotor craft to overcome the defect that in an existing multi-rotor craft, an existing engine shaft is located on the side of a craft body, a balance weight needs to be added for balancing a propeller, and consequently the effective load of the whole craft is reduced. The inner gear ring power transmission system specifically comprises a power source, a first output shaft, a second output shaft, a center gear, a first gear, a first belt wheel, a first toothed belt, a second gear, a second belt wheel, a second toothed belt, a third gear, a third belt wheel, a third toothed belt, a triple belt wheel, a rack, a first rotor, a second rotor, a first intermediate shaft and a second intermediate shaft. The inner gear ring power transmission system has the beneficial effects that a main shaft of an engine can be coaxial with a propeller shaft, the function of the same axis, the same number of revolutions and opposite rotation directions is achieved, and therefore the center of gravity of the whole craft can be more stable, the effective load of the craft is enlarged, and the control performance of the craft is improved. In addition, three toothed belt conveying systems are used, and therefore the rigidity of the whole system is improved, and reliable work of the system is ensured.
