The invention provides an underwater vehicle magnetic gear coupling propulsion system, a working method and an underwater vehicle. The underwater vehicle magnetic gear coupling propulsion system comprises an underwater vehicle shell, an electric control system, a driving motor, a magnetic gear coupler and a propeller. An electric control system and a driving motor are mounted in the underwater vehicle shell; a magnetic gear coupler is mounted at one end of the underwater vehicle shell; and the electric control system is connected with the driving motor, the driving motor is connected with the magnetic gear coupler, the magnetic gear coupler is connected with the propeller, and the propeller is arranged on the outer side of the underwater vehicle shell. The device adopts the magnetic gear coupler to realize mechanical connection of a high-speed power source in the underwater vehicle shell and a low-speed propeller outside the underwater vehicle, on one hand, a transmission mechanical reduction gear can be replaced to complete a function of matching high and low rotating speeds, and on the other hand, separation of inner and outer spaces of the underwater vehicle shell can be realized, so that dynamic and static sealing requirements are avoided, the pressure-resistant design difficulty of the system is reduced, and the sealing performance and reliability of the system are improved.
