There is transmission moment less and rotate than the difficult problem such as unstable, thus limit its application.
Summary of the invention
It is an object of the invention to provide a kind of novel magnetic bonder, by little permanent-magnetic clamp is this through big permanent-magnetic clamp
Installation by adhering mode, and the principle repelled each other according to the permanent magnet same sex, utilize the repulsion between permanent magnet that power rotor is pushed away
Dynamic drive rotor rotates, thus realizes the transmission of non-contact type magnetic torque.
Technical scheme is as follows:
The novel magnetic bonder of the present invention, including actively disk, power rotor, driven rotor, little permanent magnet, big permanent magnet,
Described active disk is fixing with power rotor to be connected；Described driven rotor includes the driven disk of hollow, and described is driven
Disk is enclosed within outside active disk, leaves space between inwall and the active disk of driven disk, and actively disk can be at driven circle
In dish freely rotatable；
Described active disk is uniformly arranged plural through hole I, described through hole I along being radially arranged, described big the most forever
Magnet is torus shape, and the external diameter of big permanent magnet is consistent with through hole I internal diameter, is installed in through hole I；
Setting through hole II on the left end wall of described driven disk, on the right-hand member wall of driven disk, the position of corresponding through hole II arranges recessed
Groove, through hole II is consistent with the internal diameter of groove, and the diameter of described through hole II and groove is less than the internal diameter of big permanent magnet；Described is little
Permanent magnet is torus, and always, little permanent magnet extends into recessed from through hole II the internal diameter of the external diameter of little permanent magnet and through hole II always
In groove；Described little permanent magnet, big permanent magnet, through hole I, through hole II, the center of circle of groove are positioned on same axis, and its projection is each other
Concentric circular；
Magnetic pole on the inner surface of described big permanent magnet is identical with the magnetic pole on little permanent magnet outer surface.
Described driven rotor is that permeability magnetic material is made.Driven rotor can be combined by upper and lower two parts, in assembling
Time upper and lower two parts be successively sleeved on actively outside rotating disk, then assembled up by securing member.
Leaving gap between described big permanent magnet inner surface and little permanent magnet outer surface, gap length is 10mm ~ 80mm.
Described big permanent magnet and little permanent magnet are radial magnetizing type permanent magnet.
The work process of the present invention is as follows:
When rotating, power rotor rotates and drives actively disk to rotate together with big permanent magnet, big owing to being embedded by little permanent magnet
In permanent magnet, and big opposite polarity between permanent magnet and little permanent magnet produces repulsion, thus promotes driven rotor to rotate；Rely on
The effect that between same sex permanent magnet, magnetic force repels each other, it is possible to transmit bigger torque, it is achieved the transmission of non-contact type magnetic torque, from
And reach the purpose of stable drive ratio.
The invention have the benefit that
The present invention by by little permanent-magnetic clamp through big permanent-magnetic clamp this installation by adhering mode, and repel each other according to the permanent magnet same sex
Principle, utilizes the repulsion between permanent magnet to make power rotor promote driven rotor to rotate, thus realizes non-contact type magnetic and turn
The transmission of square.The present invention overcomes the difficult problem that existing Non-contact Magnetic force actuators transmission moment is less, substantially increases magnetic
Moment, has widened the application of magnetic coupling.The present invention also have simple in construction, be easily installed, the advantage such as easy to operate.
