Abstract

The invention belongs to the technical field of permanent magnet driving and particularly relates to a plug-in type permanent magnet driving speed regulator. The plug-in type permanent magnet driving speed regulator comprises a conductor rotor, a permanent magnet rotor and a regulator body, wherein the conductor rotor comprises a round steel frame, an outer conductor ring and an inner conductor ring, wherein the outer conductor ring and the inner conductor ring are fixed on the round steel frame. The outer conductor ring and the inner conductor ring are concentric, and an annular cavity is formed between the outer conductor ring and the inner conductor ring. The permanent magnet rotor comprises a supporting plate and an annular mounting plate fixed on the supporting plate, wherein permanent magnet steel is evenly inlayed on the annular mounting plate. The annular mounting plate is plugged into the annular cavity in a floating mode. The conductor rotor and the permanent magnet rotor are of plug-in type structures which are coupled through magnetic force and transfer power. An axial distance between the rotors is changed through the regulator, accordingly the torque and the rotation speed are changed, the permanent magnet steel is firm in fixing and does not easily drop, rigid connection shake is avoided, the stable speed regulation of a system is achieved, meanwhile device dust accumulation is avoided, and the service life of a permanent magnet driver is greatly prolonged.

Description

A kind of plug-in permanent magnet drive speed-adjusting device
Technical field
The invention belongs to permanent magnet transmission technical field, relate 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 putting into practice industrial and mineral, tend to occur in addition dust accretions, this structure also can cause service life of equipment to reduce, or plant capacity reduces.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of plug-in permanent magnet drive speed-adjusting device is provided.
The technical scheme that the present invention 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 invention has the beneficial effects as follows: conductor rotor of the present invention and p-m rotor are taked plug in construction, both are by the magneticaction transferring power that is coupled.By adjuster, can change two axial distances between rotor, 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 be avoided rigidly connected vibrations, can realize again the stable speed governing of system, avoids 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 present invention 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 controlled the gap between p-m rotor and conductor rotor by adjuster, and controlling torque and rotating speed by inserting the depth play the function of adjusting.
