Rate.
In this case, permanent magnetic coupling is a new ideal chose in electrical machine energy-saving field.
The content of the invention
The present invention is intended to provide a kind of torque is big, the double-deck tubular turntable permanent magnetic coupling without vertical repulsive force.
To achieve the above object, present invention employs following technical solutions：
Double-layer barrel type permanent magnet clutch of the present invention, it is characterized in that：It is made of the first rotor and the second rotor, and the first rotor is cylinder
Formula p-m rotor is made of, outer magnetic ring and middle magnetic outer magnetic ring, middle magnetic ring and the internal magnetic ring of the mounting disc installation in nonferromagnetic
There is annular space between ring, have annular space between middle magnetic ring and internal magnetic ring, outer magnetic ring is by ferromagnetic outer barrel and is fixed on outer
The set of permanent magnets of cylinder inside into, internal magnetic ring by ferromagnetic inner cylinder and the set of permanent magnets that is fixed on the outside of inner cylinder into, middle magnetic ring by
The permanent magnetic disk that permanent magnet is mounted on nonferromugnetic material forms, and the second rotor is conductor rotor, thereon comprising outer conductor ring and interior
Conductor loop, the outer conductor ring on the second rotor are located in the gap of outer permanent-magnetic clamp and middle permanent-magnetic clamp, outer conductor ring by air gap with
Outer permanent-magnetic clamp and the permanent magnet on middle permanent-magnetic clamp pass through into coupled relation, inner wire ring on air gap and middle permanent-magnetic clamp and interior permanent-magnetic clamp
Permanent magnet into coupled relation.Uniformly distributed permanent magnetism is enclosed in outer magnet ring, middle magnet ring and interior magnet ring, thereon each installation one
Body, permanent magnet magnetic extreme direction is vertical with turntable axis, the heteropolar installation of adjacent magnets magnetic pole.The first rotor is connected with first axle, the
Two rotors are connected with the second axis, can input shaft or output shaft each other.
Compared with prior art, the beneficial effects of the invention are as follows：
Magnet on permanent magnetic rotation disc divides N, S pole arranged adjacent, and the magnetic line of force passes through corresponding conductor cylinder, opposite when between the two
Both during movement, conductor cylinder cutting magnetic line generates vortex flow, vortex flow and then generation dislike magnetic field in conductor cylinder, prevent
Between relative motion, so as to fulfill between the two torque transfer, achieve the purpose that isolation vibration, reduction of speed it is energy saving.
While the contactless transmission of power is realized, axial thrust is avoided, adds coupling area, at the start
The complete starting under no load of motor can be achieved, can realize that different torques transfers by the adjusting of coupling area between rotor, reach isolation
The energy saving purpose of vibration, reduction of speed, while installation and debugging are fairly simple, allow certain axial float.
