Should.After input shaft and output shaft step-out, the conductor of conductor, driven shaft on power rotor is produced respectively at the permanent magnet of other side
Raw relative motion, permanent magnetic field produces vortex in conductor on permanent magnet, while vortex produces induced field again and permanent magnetic field is mutual
Effect, finally promotes, power rotor, driven rotor run-in synchronism.The utility model is when can prevent equipment stall to prime mover
Mortal injury, in equipment stall can moment step-out reduce moment of torsion transmission, synchronization can be automatically replied after Failure elimination, without stopping
Machine, restarting, so as to reduce injury of the stall to prime mover.
Described driven rotor is in hollow cylinder, power rotor end face connection input shaft, other end with power rotor
Opening；Driven rotor end face connects output shaft, other end opening；The power rotor, driven rotor are nested together, and
In the circumferentially-spaced magnetic pole that permanent magnet on conductor and permanent magnet, power rotor and driven rotor is distributed with of two rotor sidewalls circumferentially
Or arranged radially, and adjacent pole polarity is different.
Described driven rotor and power rotor are in the form of annular discs, power rotor side connection input shaft, between opposite side circumference
Every conductor and permanent magnet is distributed with；Driven rotor side connects output shaft, and opposite side is circumferentially-spaced to be distributed with conductor and permanent magnet,
Circumferentially or arranged radially, and adjacent pole polarity is different for the magnetic pole of permanent magnet on power rotor and driven rotor；Power rotor,
The side that permanent magnet is distributed with driven rotor is relative.
For ease of abundant cutting magnetic induction line, outside the nested rotor that the described power rotor of correspondence, driven rotor are constituted
Side face and inner peripheral surface connect conductor rotor on power rotor and driven rotor respectively so that on power rotor and driven rotor
Conductor rotor is adjacent with the permanent magnet of other side.Conductor rotor inside and outside nested rotor collectively constitutes closing space, reduces leakage field, together
When reduce outer magnetic to internal interference, also reduce internal influence to external world, isolation shakes, and extends service life.
It is preferred that, the nested rotor of composition in described driven rotor insertion power rotor turns in driven rotor periphery, active
The sub- nested rotor outer periphery face of inner circumferential correspondence and inner peripheral surface connect conductor rotor respectively.
Described power rotor, driven rotor be distributed with permanent magnet side it is relative constitute relative rotor, correspondence is described
The outer peripheral face and inner peripheral surface for the relative rotor that power rotor, driven rotor are constituted connect on power rotor and driven rotor respectively
Connect conductor rotor.Conductor rotor inside and outside relative rotor collectively constitutes closing space, reduces leakage field, while reducing outer magnetic to inside
Interference, also reduce internal influence to external world, isolation vibrations extend service life.
The utility model carries out moment of torsion transmission by the way of conductor cutting magnetic induction line, in the jiggly power transmission of rotating speed
In, with buffering, vibration damping and the effect for improving shafting dynamic property.The drawbacks of conventional shaft coupling is brought is changed, extends and sets
Standby service life, improves bearing capacity and after extraneous obstacle causes to input, exports step-out, makes it quick same using slippage
Step, without restarting.
