The invention discloses a jet flow direct-drive type rotation drive. The drive comprises an inlet connector connected with a high-pressure fluid input end. An inner ring is connected with the inlet connector through a bearing. A fluid channel is arranged on the inner ring. A nozzle is arranged at the output end the fluid channel. The nozzle is communicated with the fluid channel and an inner cavity of the inlet connector. The periphery of the inner ring is provided with an outer ring. A left end cover and a right end cover are arranged on the two sides of the inner ring respectively. The inner ring is connected with the inner side of the left end cover and the inner side of the right end cover through bearings. The outer ring is connected with the outer side of the left end cover and the outer side of the right end cover through bearings. The inner surface of the outer ring is in a sawtooth shape. After the jet flow direct-drive rotation drive is connected with the external high-pressure fluid input end, the inner ring of the drive can rotate under the action of jet flow reaction thrust, meanwhile, and the sawtooth face of the outer ring rotates in the direction opposite to the inner ring under the action of jet flow impact force of liquid sprayed by the nozzle. By means of the structural design, the development of the technology for comprehensively utilizing jet flow reaction thrust and jet flow impact force is accelerated.
