The transmission of sub and outer magnet rotor torque.
The second axle body is input shaft, and the first axle body is output shaft, adjusts modulation ring and interior magnet rotor and outer magnet rotor
Engagement is, it can be achieved that the speedup of transmission system subtracts torsion；It adjusts modulation ring to disengage with interior magnet rotor and outer magnet rotor, then magnetic turns in disconnection
The transmission of sub and outer magnet rotor torque.
Advantageous effect：A kind of rare-earth permanent-magnet variable-speed clutch of the present invention makes modulation ring edge by adjusting adjuster
The first axle body moves axially to change the active area between interior magnet rotor and outer magnet rotor, and then changes interior magnet rotor and outer magnetic
Transmission torque between rotor, both may be implemented the transmission and disconnection of torque, can also play and subtract during torque transmits
The effect of speed or speedup has simple in structure, non contact transmission torque, is protected without abrasion, without lubrication, light-load starting and overload
Shield, high reliability.
