1. , a kind of coupler, it comprises:

  • First and second rotation axiss with rotating shaft;

    Two coaxial magnet rotors, its each rotor comprises respectively organizes permanent magnet;

    Two coaxial conductor rotor, its each rotor has non-iron conducting ring, and one of itself and described each magnet group be certain interval at interval;

    The axial distance that described preceding two rotor spaces are fixing, and be installed in integratedly on described first, so that rotate in concert with it;

    Two remaining described rotors then be mounted to described second rotate in concert, and can move axially in an opposite direction with respect to described second, thereby become coupling and uncoupling relation with described preceding two described rotors;

    The magnetic shrink-down material interacts with described permanent-magnet clusters respectively with described conductor rotor, and described rotor magnetic biasing is pressed into described coupled relation;

    One assembly is accompanied by described rotor, axial motion in the moving range between minimum and maximum described gap between described magnet rotor and the described conductor rotor, described minimum clearance is exactly to make to make axial thrust surpass described bias voltage because of overload makes the slip between the described axle, and described coupler is broken away from;

    WithThe adjustable limiting device is in order to regulate described minimum clearance.
