Abstract
The invention relates to a permanent-magnet torque-limiting shaft coupler, and the shaft coupler comprises an input shaft and an output shaft. One end of the input shaft is connected with a driving rotor, and one end of the output shaft is connected with a driven rotor. The driving rotor and the driven rotor are respectively provided with conductors and permanent magnets in the peripheral direction at intervals. The conductors and the permanent magnets on the driving rotor and the driven rotor are corresponding in a one-to-one manner. The shaft coupler carries out the torque transmission in a mode that the conductors cut magnetic induction lines, and has the buffering and damping effects and an effect of improving the dynamic performance of a shaft system in the power transmission with the instable rotating speed. The shaft coupler irons out the defects of a conventional shaft coupler, prolongs the service life of equipment, improves the bearing capability, enables the input and output to be synchronous quickly through slip frequency after an external barrier causes the desynchrony of the input and output, and does not need to restart.

Permanent magnet clutch lead to because of equipment stall to need after input and output step-out shut down, restart and can run.In addition, it is existing
Positive coupling the axiality of driving shaft and driven shaft is required higher, increase manufacture difficulty.
Content of the invention
For the problems referred to above, the present invention provides a kind of equipment stall step-out, can automatically reply synchronous after Failure elimination
Permanent magnet torque-limiting shaft coupling.
For solving the above problems, the technical scheme that the present invention takes is：A kind of permanent magnet torque-limiting shaft coupling, including input shaft and
Output shaft, described input shaft one end connects power rotor, and output shaft one end connects driven rotor, power rotor and driven rotor
On all circumferentially-spaced conductor and permanent magnet be distributed with, the conductor on power rotor and driven rotor and permanent magnet correspond.
After input shaft and output shaft step-out, conductor on power rotor, the conductor of driven shaft are respectively at other side forever
Magnet produces relative motion, and permanent magnetic field produces vortex in conductor on permanent magnet, and vortex produces induced field and permanent magnetism again simultaneously
Field interactions, finally promotes, power rotor, driven rotor run-in synchronism.The present invention can prevent during 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, need not
Shutting down, restarting, thus reducing the injury to prime mover for the stall.
Described driven rotor and power rotor are in hollow cylinder, and power rotor end face connects input shaft, other end
Opening；Driven rotor end face connects output shaft, other end opening；Described power rotor, driven rotor nest together, and

Or arranged radially, and adjacent pole polarity is different.
Described driven rotor is in the form of annular discs with power rotor, and power rotor side connects input shaft, between opposite side circumference
Every conductor and permanent magnet are distributed with；Driven rotor side connects output shaft, and opposite side is circumferentially-spaced to be distributed with conductor and permanent magnet,
On power rotor and driven rotor, circumferentially or arranged radially, and adjacent pole polarity is different for the magnetic pole of permanent magnet；Power rotor,
Driven rotor is distributed with the side of permanent magnet relatively.
Outside the nested rotor being formed for ease of abundant cutting magnetic induction line, corresponding described power rotor, driven rotor
Side face and inner peripheral surface connect conductor rotor respectively so that on power rotor and driven rotor 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, with
When reduce outer magnetic to internal interference, also reduce internal impact to external world, isolation shakes, and extends service life.
Preferably, the nested rotor of composition in described driven rotor insertion power rotor, in driven rotor periphery, actively turns
Sub- inner circumferential corresponding nesting rotor outer periphery face and inner peripheral surface connect conductor rotor respectively.
The side that described power rotor, driven rotor are distributed with permanent magnet forms relative rotor relatively, corresponding described
The outer peripheral face of the relative rotor that power rotor, driven rotor are formed and inner peripheral surface connect respectively on power rotor and driven rotor
Connect conductor rotor.Conductor rotor inside and outside relative rotor collectively constitutes closing space, reduces leakage field, reduces outer magnetic to inside simultaneously
Interference, also reduce internal impact to external world, isolation vibrations, extend service life.
The present invention carries out moment of torsion transmission by the way of conductor cutting magnetic induction line, in the jiggly power transmission of rotating speed,
There is buffering, vibration damping and the effect improving shafting dynamic property.The drawbacks of changing conventional shaft coupling and bring, extend equipment
Service life, improves bearing capacity and after extraneous obstacle leads to input, exports step-out, makes its Fast synchronization using slippage,
Without restarting.
