[0003] At present, the speed regulating mechanism of the speed regulating magnetic coupling adjusts the size of the air gap mainly through the actuator to push a single connecting rod to drive the two permanent magnet rotors to move axially, and through the connecting body and gear teeth between the two permanent magnet rotors The bar-type mechanism realizes synchronous phase-to-phase movement. Its parts are complex, large in number, high in machining accuracy, difficult to assemble, easy to wear out parts, large in transmission synchronization error, large in axial movement resistance, and large in required transmission torque. Stuck, which has a large impact on the bearing, reduces the accuracy of the speed regulating system, and affects the application performance and operation stability of the speed regulating magnetic coupling
