Abstract
The utility model discloses a shell and directly operated brake electromagnet, which is mainly used for a short travel brake. A short magnetic path, high magnetic flux density design and dual power supply are adopted by the utility model. A brake rod is directly pushed by a moving armature, the electromagnet works at the end surface force segment of the electromagnetic force, and thus compared with a normal rotary electromagnet, copper can be saved more than 50%. The utility model has the advantages of small size, big action force and safety. The utility model is characterized in that the moving armature adopts a reciprocal motion, the brake rod is directly driven by the moving armature, the rated travel of the moving armature can be limited by a limited plate, the rated travel is equivalent to the rated displacement of the brake, demagnetizing clearance and the magnetic leader on a static iron can be realized, and the electromagnet works on one end surface force segment which has a greater force value.
Description
The utility model relates to a kind of direct drive type electro magnet that is applied to the short stroke brake.
Existing MZDI series electromagnet is an Alternating Current Power Supply, and the rotary type electromagnet is the power that produces the promotion brake bar by the boosting function of lever.Its deficiency is that bulky, consumable quantity is big, mechanism's complexity, and there are relative displacement in electromagnet and brake brake bar joint and produce frictional force, and frictional force produces a moment again to brake bar.When needing the nargin of increased force will, have only by strengthening the weight and volume of electromagnet for keeping electromagnet effectively to work.Produce same power and need select bigger coil and iron core for use.
The purpose of this utility model is to provide the little brake electromagnet that again can safety and reliability work of a kind of low power consuming, high-effect, volume newly to design.
The supply power mode that a kind of electromagnet is new is widely adopted, is about to alternating current is transformed to big current start, the maintenance of little electric current through one group of conversion, control circuit two direct current supplys.The utility model is under this supply power mode, and the electromagnet that is primarily aimed at the brake of short stroke is done to improve.Change former rotary type into Direct Action Type, brake bar in order to direct promotion brake, adopt short magnetic circuit, high-magnetodensity design to make work of electromagnet, magnetic boot segment and degaussing air gap are set, under the effect of brake spring power, can throw off voluntarily to guarantee electromagnet outage back in the end force section of skyrocketing.
Its composition of the utility model comprises a coil with through hole, its active section inserts the moving armature of described coil through hole, under the effect of hot-wire coil electromagnetic force, clap the quiet iron that closes with the formation magnetic loop for one with moving armature, the fitting surface corresponding with the moving armature active section has one section magnetic boot segment that stretches in the coil solenoid on the quiet iron, moving armature both sides and quiet iron joint all leave the degaussing air gap, also has an AC-DC conversion, control circuit, it is characterized in that: have the confession brake bar over against armature fitting surface place on the quiet iron and stretch in order to contact the hole of armature, described moving armature is reciprocating motion, the brake bar of brake stretches into quiet iron perforate, push up to the moving armature fitting surface, moving armature directly promotes the brake bar of brake; The moving armature upper fixed has limiting plate, leaves the moving armature action gap suitable with the brake bar rated displacement between the moving armature when limiting plate and closure state; Adopt short magnetic circuit, high-magnetodensity design, promptly the height of electromagnet and the ratio of its width be less than 1, and the ratio of coil height and width is less than 2.The improvement that the utility model is more practical is that a rebound is housed, to realize substituting MZDI series electromagnet and TJ
2The type brake links.
The utility model is owing to be operated in the electromagnet end force section of skyrocketing, during supporting same specification brake, than MZDI series electromagnet joint copper-steel material material 75～83%, the electromagnet manufacturing cost descends significantly, and the electromagnet moving armature directly promotes brake bar, removes brake coherence and damping, dual power supply makes holding current be heating current not, the electromagnet frequency improves more than 10 times, even in the work of high frequency points flowing mode, also be unlikely and burn coil.The electromagnet noiseless operation.
Accompanying drawing 1 is the utility model example structure figure.
Describe the technical scheme details in detail below in conjunction with accompanying drawing.
The active section of T type moving armature 2 is inserted into coil 5 through holes, and quiet iron 4 is around coil 1, and (5) are arranged.Leave the degaussing air gap in 0.1～0.5mm gap at moving armature T type both sides and quiet iron joint, after guaranteeing the electromagnet outage, under the effect of brake spring power, can throw off voluntarily.Quiet iron 4 leaves the magnetic boot segment of certain altitude at corresponding moving armature active section, and this boot segment has a through hole, and the system brake bar 7 of brake stretches in the hole, pushes up to moving armature 2 fitting surfaces, and it is reciprocating that moving armature directly promotes brake bar.One copper sheathing 8 is arranged, in order to motion of guiding moving armature and minimizing leakage field between magnetic boot segment and the coil hole.A U type location-plate 3 is fixed on moving armature top and the quiet iron in both sides thereof, leaves a gap between location-plate 3 and moving armature, equals the brake bar rated displacement with restriction moving armature rated travel.In order to substitute MZDI series electromagnet, install a rebound 6 additional and be convenient to and TJ
2The series brake connects.The utility model power supply circuits known technology, not shown in the accompanying drawing, at this not in narration.
Implement the present invention on 25Kg power, 8.3mm short stroke brake, the h that knits the brows meter is of a size of, length 82mm, high 60mm, thickness 42mm, and coil long 1 is established air gap 0.1mm, the heavy only 1Kg of iron, the heavy 0.1Kg of copper is at 130 ℃, under the 187V voltage, the actual measurement tripping force is 50Kg, and confining force is 30Kg, directly TJ
