The invention relates to the technical field of stratospheric airships, and discloses a propeller linkage driving device shafting and stratospheric airship. The airship comprises an outer rotor, an inner stator, a first bearing, a second bearing, a third bearing, an outer rotor shaft, an outer rotor shaft support frame, an inner stator shaft and an inner stator shaft support frame; one end of the outer rotor shaft is fixedly connected with the propeller, and the other end is fixedly connected with the outer rotor; the outer rotor encloses the inner stator, one end of the inner stator shaft is fixedly connected with the inner stator, and the other end of the inner stator shaft is fixedly connected with the inner stator shaft support frame; the first bearing and the second bearing are both arranged on the outer rotor shaft, and a preset distance is reserved between the first bearing and the second bearing; inner rings of the first bearing and the second bearing are connected with the outer rotor shaft, and outer rings of the first bearing and the second bearing are connected with the outer rotor shaft support frame; and the outer ring of the third bearing is connected with the hole wall of the through hole of the outer rotor, and the inner ring is connected with the inner stator shaft. The three stress bearings are adopted, torsion borne by the first bearing is reduced, and therefore the service life of the bearings is prolonged.
