Clutch pushing device 10 is connected to described outer magnet rotor 6, drives outer magnet rotor 6 along power shaft 8 axially-movable, makes outer magnet rotor 6 and interior magnet rotor 2 relative motion. When interior magnet rotor 2 is in released state with outer magnet rotor 6, the first high-magnetic-density magnetic sheet 21 of described interior magnet rotor 2 and the second high-magnetic-density magnetic sheet 61 of outer magnet rotor 6 from, be absent from magneticaction between the two; When the circular containing groove that clutch pushing device 10 makes interior magnet rotor 2 enter outer magnet rotor 6, the distance of described first high-magnetic-density magnetic sheet 21 and the second high-magnetic-density magnetic sheet 61 is more and more nearer, until overlapping (i.e. state shown in Fig. 1), being combined by magnetic force to magnet rotor in process 2 with outer magnet rotor 6, namely realize transmission by magnetic force.
This utility model embodiment utilizes high magnetic magnetic sheet to realize the transmission of power, between interior magnet rotor and outer magnet rotor and contactless. Therefore, it is absent from interior magnet rotor and the wear phenomenon at outer magnet rotor transmission power place, has possessed the effect without abrasion.
In the present embodiment, described clutch pushing device includes hydraulic cylinder 3, briquetting 4, axial thrust bearing 5 and spring 7;
