Abstract

The utility model belongs to the technical field of permanent magnetic driving, and especially relates to a plug-in type permanent magnetic driving speed governor. The speed governor includes a conductor rotor, a permanent magnetic rotor and a regulator. The conductor rotor comprises a circular steel frame, and an outer connector ring and an internal conductor ring which are fixed on the circular steel frame. The outer conductor ring and the internal conductor ring are arranged with the same center of a circle and form an annular cavity between them. The permanent magnetic rotor comprises a support disk and an annular installation disk fixed on the support disk. Permanent magnetic steels are embedded uniformly in the annular installation disk which is floatedly inserted into the annular cavity. The conductor rotor and the permanent magnetic rotor utilize plug-in type structures and coupledly transmit power by magnetic force effect. The torque and the rotate speed are changed by changing axial distance between two rotors by the regulator. The permanent magnetic steel is fixed firmly and is not easy to fall off. The shock of rigid connections is avoided, the stabilization speed regulation is achieved, the dust accumulation is prevented, and the service life of a permanent magnetic driver is prolonged substantially.

Description

A kind of plug-in permanent magnet drive speed-adjusting device
Technical field
The utility model belongs to permanent magnet transmission technical field, relates in particular to a kind of plug-in permanent magnet drive speed-adjusting device.
Background technology
Permanent magnet transmission technology is in the quite aobvious effect of application of some technical fields at present, and the advantage of this technology is: reduce systematic running cost and use; Machinery-free connects, and reduces loss, without friction and abrasion components and parts; Installation and Debugging process simplification, has thoroughly eliminated the impact of thermal expansion on parts; Do not produce harmonic wave, not affected by voltage ripple of power network; Motor can be realized more steady and progressive flexible start/stop; No Load Start, reduces motor peak current, and starting current is less than 1.5 times of normal value, has improved the reliability of whole motor driven systems.Use permanent-magnet coupler can reduce the startup power consumption of motor and avoid causing larger voltge surge; Dwindle the capacity of motor; The soft start of real band buffering, at utmost reduces the impact to motor and load of motor start-up and brake process; Reduce system maintenance cost, significantly extend motor and load bearing life, significantly extend motor and load seal life-span; Long service life, can reach 30 years designed life etc., and these self technical advantage is significant.
The permanent magnet transmission structure of prior art is two relative types of conductor rotor and p-m rotor, is embedded in like this opposite of described conductor rotor due to the magnet piece on p-m rotor, affected by magnetic attraction and comes off, and then form potential safety hazard or cause device damage.In industrial and mineral, tend to occur that dust accretions, this structure also can cause service life of equipment to reduce putting into practice in addition, or plant capacity reduces.
Utility model content
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of plug-in permanent magnet drive speed-adjusting device.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of plug-in permanent magnet drive speed-adjusting device, comprise conductor rotor, p-m rotor and adjuster, its special character is that described conductor rotor comprises circular steelframe and is fixed on outer conductor ring and the inner wire ring on described circular steelframe; Described outer conductor ring and inner wire ring concentric are arranged, are formed toroidal cavity between the two; Described p-m rotor comprises supporting disk and is fixed on the annular mounting disc on supporting disk, in described annular mounting disc, is evenly inlaid with permanent magnetic steel; Described annular mounting disc is floated and is inserted in described toroidal cavity.
The beneficial effects of the utility model are: conductor rotor of the present utility model and p-m rotor are taked plug in construction, and both are by the magneticaction transferring power that is coupled.Can change two axial distances between rotor by adjuster, thereby change torque and rotational speed, reach the object of speed governing.Compared to existing technology, its permanent magnetic steel is fixed, and difficult drop-off both can have been avoided rigidly connected vibrations, can realize again the stable speed governing of system, avoided the generation of harmonic wave; Avoid the accumulation of equipment dust simultaneously, greatly improve the useful life of magnetic actuator.
On the basis of technique scheme, the utility model can also do following improvement.
Further, be evenly inlaid with 15 groups of permanent magnetic steels in described annular mounting disc, between adjacent permanent magnetic steel, N, the S utmost point are alternately arranged.
Further, described conductor rotor is connected with motor shaft by flange; Described supporting disk is connected with load by described adjuster.
Adopt the beneficial effect of above-mentioned further scheme to be, p-m rotor is by the gap between adjuster control p-m rotor and conductor rotor, and controlling torque and rotating speed by inserting the depth play the function of adjusting.
