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 on clapping type, helix tube type, E type electromagnet and the coiled electrical magnet etc. in addition of magnetic force work in addition, the electromagnet structure of these forms generally all is an iron yoke, a coil and a composition such as armature, coil is arranged in the iron yoke, by can making armature carry out the adhesive action for coil electricity, its operating principle is 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 Chang Yong magnetic clutch connected member 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 made up 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 drive armature and rotate in rotation process, armature further drives axle sleeve and rotates, outage back armature separates with axle sleeve, 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 torque transmitted 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 and the outer wall of interior armature are provided with corresponding notch, and coil is embedded in the iron yoke.
Described coil is embedded in and is meant in the iron yoke in the iron yoke and has circular groove, and coil is wrapped in the circular groove.Outer armature is made up of two kinds of materials, and the part over against coil on axial direction is a non-magnet material, and remaining part is a 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, make under the driving of drive motor that when coil electricity driving shaft and driven shaft are rotated together, when stopping to coil electricity, driving shaft and driven shaft can be distinguished rotation alone.
(2) coil is sealed in the circular groove of iron yoke, has avoided the influence of etchant gas to coil, has well guaranteed the service behaviour of magnetic clutch.
(3) inside and outside armature is provided with corresponding notch, and 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 makes and produce 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 torque transmitted is bigger, 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 made up 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 influence of etchant gas to 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 made up of two kinds of materials, and the part over against coil 2 on axial direction is a non-magnet material, and remaining part is a permeability magnetic material.As shown in Figure 2, the inwall of outer armature 3 is provided with the notch of some, and the notch of corresponding some with it 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 the magnetic pole (part between notch and the notch) of inside and outside armature 4,3, thereby makes and produce 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 produce suction between armature 4, the outer armature 3 in making.
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 galvanizations, to between iron yoke 1, outer armature 3, interior armature 4, form magnetic circuit, because of magnetic circuit always forms the loop along the direction of magnetic resistance minimum, promptly can make inside and outside armature 4,3 move towards the direction that magnetic pole overlaps with magnetic pole, armature 4, outer armature 3 are pulled together in making, 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 galvanizations, magnetic field between interior armature 4, the outer armature 3 will disappear, the suction-combining force disappearance between armature 4, the outer armature 3 in making, the Transmitted chains at armature 4 and outer armature 3 places disconnects in causing, thereby make the Transmitted chains of driver part and power unit disconnect, 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 the excellent function that falls fast.
