Description
Technical field
The present invention relates to the reactor engineering technical field, particularly a kind of magnetic clutch of suitable reactor operating mode.
Background technique
Magnetic clutch is used very extensive in industry, and castellated, dry type single-deck, torsional spring type, magnetic particle coupling are arranged.Lean in addition in addition clapping type, helix tube type, E type electromagnet and the coiled electrical magnet etc. of magnetic working, the electromagnet structure of these forms generally all is an iron yoke, a coil and the composition such as armature, coil is arranged in the iron yoke, by giving the coil electricity can be so that armature is carried out the adhesive action, its operating principle be fairly simple.Magnetic clutch coil commonly used is not sealed in the iron yoke, does not also have notch on the armature, and coil adopts conventional arrangement.The juncture of magnetic clutch connected member commonly used is by rigidity, magnetic force and mechanical force associating or friction mode in addition, and the throw-out-of clutch time is longer.For example, existing torsional spring type magnetic clutch mainly is comprised of driving disc, screwing spring, axle sleeve, armature, coil, iron yoke etc., its working principle is to link to each other with armature to the coil electricity rear axle housing, driving disc screwing spring and be with moving armature to rotate in rotation process, armature further drives axle sleeve and rotates, armature separates with axle sleeve after the outage, and axle sleeve stops operating.The clutch of this structure can only transmit unidirectional torque, be applicable in the small-sized machine of low speed, low inertia, and the torque of transmitting is less.
At present, existing magnetic clutch can't satisfy the needs of reactor, therefore is badly in need of the magnetic clutch of a kind of suitable reactor internal environment needs of development.
Summary of the invention
The present invention has overcome deficiency of the prior art, and a kind of simple in structure, magnetic clutch that can transmit the short suitable reactor needs of two-way torque, disengagement time is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of magnetic clutch comprises iron yoke, coil, armature, and key is that this device is telescoping structure, and armature is divided into telescopic outer armature and interior armature, and the inwall of outer armature is provided with corresponding notch with the outer wall of interior armature, and coil is embedded in the iron yoke.
Described coil is embedded in and refers in the iron yoke have circular groove in the iron yoke, and coil winding is in circular groove.Outer armature is comprised of bi-material, and the part over against coil on axial direction is non-magnet material, and remaining part is permeability magnetic material.
Compared with prior art, the invention has the beneficial effects as follows:
(1) this device adopts telescopic inside and outside armature, apparatus structure is simple, and can be with inside and outside armature respectively as driving shaft and driven shaft, when coil electricity under the driving of drive motor so that driving shaft and driven shaft be rotated together, when stopping to coil electricity, driving shaft and driven shaft can be distinguished alone rotation.
(2) coil is sealed in the circular groove of iron yoke, has avoided the impact of etchant gas on coil, has well guaranteed the service behaviour of magnetic clutch.
(3) be provided with corresponding notch at inside and outside armature, magnetic line of force major part is to form magnetic circuit along the magnetic pole of inner and outer sleeves armature (part between notch and the notch), thereby so that produces peripheral force between the inner and outer sleeves armature.Inside and outside armature by the magnetic force combination, can transmit two-way torque fully, and the torque of transmission is larger, and the disengagement time of clutch is short.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
A kind of magnetic clutch, as shown in Figure 1, magnetic clutch is telescoping structure, and it mainly is comprised of iron yoke 1, coil 2, outer armature 3, interior armature 4, wherein has circular groove 5 on the iron yoke 1, and circular groove 5 is embedded in coil 2.Coil 2 is sealed in the iron yoke 1, has avoided the impact of etchant gas on coil 2, can guarantee the service behaviour of magnetic clutch.Iron yoke 1, outer armature 3 and interior armature 4 are respectively telescoping structure, and outer armature 3 and interior armature 4 are installed in the iron yoke 1, leave the gap between iron yoke 1, outer armature 3, the interior armature 4.Outer armature 3 is comprised of bi-material, and the part over against coil 2 on axial direction is non-magnet material, and remaining part is permeability magnetic material.As shown in Figure 2, be provided with the notch of some on the inwall of outer armature 3, the with it notch of corresponding some also is set on the outer wall of interior armature 4.And magnetic circuit always forms the loop along the path of magnetic resistance minimum, so magnetic line of force major part is to form magnetic circuit along inside and outside armature 4,3 magnetic pole (part between notch and the notch), thereby so that produces peripheral force between the inside and outside armature 4,3.Interior armature 4 and outer armature 3 are connected member, and its juncture makes the disengagement time of clutch short fully by the magnetic force combination like this.
The winding direction of coil 2 in circular groove 5 is the circumferencial direction of interior armature 4, outer armature 3, by the magnetic line of force through iron yoke 1, outer armature 3, interior armature 4 along forming magnetic loop on the axial direction of coil 2, thereby so that produce suction between the interior armature 4, outer armature 3.
This device links to each other with reactor control rod driving mechanism, and outer armature 3 is connected with the motor driving parts, and as the output terminal of driver part, interior armature 4 is connected with power unit, as the input end of power unit.
When giving coil 2 galvanization, to between iron yoke 1, outer armature 3, interior armature 4, form magnetic circuit, because magnetic circuit always forms the loop along the direction of magnetic resistance minimum, namely can be so that the direction motion that inside and outside armature 4,3 overlaps with magnetic pole towards magnetic pole, so that interior armature 4, outer armature 3 are pulled together, the driver part of control rod and the Transmitted chains of power unit can be coupled together, under the effect of motor driving power, control rod be moved up and down.
When stopping to coil 2 galvanization, magnetic field between interior armature 4, the outer armature 3 will disappear, make the suction-combining force disappearance between interior armature 4, the outer armature 3, cause the Transmitted chains at interior armature 4 and outer armature 3 places to disconnect, thereby so that the disconnection of the Transmitted chains of driver part and power unit, thereby the Transmitted chains of having realized interior armature 4, outer armature 3 places can move separately.After the Transmitted chains at interior armature 4 places rotated separately, control rod drive mechanisms (CRD) was finished quick scram function.
