There is transmit torque it is smaller and rotation than the problems such as unstable, to limit its application.
Invention content
The purpose of the present invention is to provide a kind of novel magnetic couplers, by passing through big permanent-magnetic clamp this small permanent-magnetic clamp
Installation by adhering mode, and according to the permanent magnet principle that identical charges repel each other, using the repulsion between permanent magnet power rotor is pushed away
Dynamic drive rotor rotation, to realize the transmission of non-contact type magnetic torque.
Technical scheme is as follows：
The novel magnetic coupler of the present invention, including active disk, power rotor, driven rotor, small permanent magnet, big permanent magnetism
Body, the active disk are fixedly connected with power rotor；The driven rotor includes hollow driven disk, it is described from
Dynamic disk is sleeved on except active disk, and there are gaps, active disk between the inner wall and active disk of driven disk can be driven
It is freely rotated in disk；
The active disk is uniformly arranged more than two through-hole I, and the through-hole I is described along radial setting
Big permanent magnet is torus shape, and the outer diameter of big permanent magnet is consistent with through-hole I internal diameters, is installed in through-hole I；
Through-hole II is set on the left end wall of the driven disk, the position that through-hole II is corresponded on the right end wall of driven disk is set
Groove is set, through-hole II is consistent with the internal diameter of groove, and the diameter of the through-hole II and groove is less than the internal diameter of big permanent magnet；It is described
Small permanent magnet be torus, always, small permanent magnet extends always from through-hole II for the outer diameter of small permanent magnet and the internal diameter of through-hole II
Enter in groove；The small permanent magnet, big permanent magnet, through-hole I, through-hole II, groove the center of circle be located on same axis, project
Concentric circles each other；
Magnetic pole on the inner surface of the big permanent magnet is identical as the magnetic pole on small permanent magnetism external surface.
The driven rotor is made of permeability magnetic material.Driven rotor can be composed of upper and lower two parts, assembled
When up and down two parts successively be sleeved on except active turntable, then assembled up by fastener.
There are gap between the big permanent magnet inner surface and small permanent magnetism external surface, gap size is 10mm ~ 80mm.
The big permanent magnet and small permanent magnet are radial magnetizing type permanent magnet.
The course of work of the present invention is as follows：
In rotation, power rotor rotation drives active disk and big permanent magnet to rotate together, since small permanent magnet is embedding
Enter in big permanent magnet, and big polarity between permanent magnet and small permanent magnet is opposite generates repulsion, to push driven rotor to rotate；
By the effect that magnetic force repels each other between same sex permanent magnet, larger torque can be transmitted, realizes the biography of non-contact type magnetic torque
It passs, to achieve the purpose that stable drive ratio.
Beneficial effects of the present invention are：
The present invention by small permanent-magnetic clamp by passing through this installation by adhering mode of big permanent-magnetic clamp, and according to permanent magnet same sex phase
The principle of reprimand makes power rotor that driven rotor be pushed to rotate, to realize Non-contact Magnetic using the repulsion between permanent magnet
The transmission of power torque.The present invention overcomes the problems, such as that existing Non-contact Magnetic force actuators transmission torque is smaller, greatly improves
Magnetic torque, has widened the application field of magnetic coupling.The present invention also have it is simple in structure, be easily installed, be easy to operate etc.
Advantage.
