Description
Technical field
But the utility model relates to the electromagnet that a kind of armature straight line moves, specifically a kind of no-oil lubricant dual-push electromagnetic iron.
Background technology
At present, in elevator brake, widely adopt the brake opening device of dual-push electromagnetic iron as brake.The structure of dual-push electromagnetic iron is that two solenoids and two moving iron cores (armature) are housed in tubular shell (yoke), and the core body of moving iron core is supported in the housing inner chamber, and the mandrel of moving iron core is supported in the core hole on housing or the housing end plug.In order not influence magnetic conductive loop and can to produce a bigger electromagnetism motive force, the moving iron core of dual-push electromagnetic iron generally is to select for use pure iron or the good mild steel of magnetic property to make; And in order to prevent magnet short-cut path, the mandrel of moving iron core generally is with non-magnetic metal material such as making such as stainless steel or copper.Because these metal materials can not be done the Quenching Treatment of sclerosis, the resistance to wear of therefore moving iron core is not high.In long-term elevator operation, braking procedure, on the moving core support friction pair of electromagnet, will wear and tear, thereby form rough surface because of friction produces, severe patient will produce and move core jam phenomenon, makes misfunctioning of brake, causes serious consequence.
The utility model content
The purpose of this utility model just provides a kind of no-oil lubricant dual-push electromagnetic iron, to reduce even to exempt the maintaining of the used dual-push electromagnetic iron of elevator brake, improves the safety in utilization of elevator brake.
The utility model is achieved in that no-oil lubricant dual-push electromagnetic iron is that two solenoids and two moving iron cores are housed in tubular shell, the core body of moving iron core is supported in the housing inner chamber, the mandrel of moving iron core is supported in the core hole on housing or the housing end plug, supports on the friction pair being provided with the ceramic spraying layer at the moving core of electromagnet.
The utility model is the method with thermal spraying, with engineering ceramic material under the high temperature melt state, the moving core of high velocity jet in the dual-push electromagnetic iron supports one of them or the surface of two slide relative friction means on the friction pair, makes it to form the sprayed coating of an engineering ceramics.Because the thickness of ceramic spraying layer is extremely thin, magnetic property to electromagnet almost has no effect, and utilize the self-characteristic of engineering ceramics, but can make the moving core support friction pair of electromagnet can improve anti-wear performance significantly, and making friction pair have self-lubricating function, the phenomenon that so just can avoid moving core to support the parts surface wearing and tearing fluffing of friction pair effectively takes place.Because moving core supports the phenomenon that will no longer produce the wearing and tearing fluffing on the friction pair, therefore, the former promising moving designed bigger processing fit clearance of core jam of fluffing initiation of avoiding wearing and tearing just can be dwindled on moving core support friction pair, and this has promoted the raising of electromagnet magnetic property conversely.
After the moving core of electromagnet supports friction pair position gunite work pottery, not only make these positions have very high resistance to wear and self lubricity, the friction mechanism that also makes the moving core of electromagnet support on the friction pair simultaneously changes to some extent:
---existing electromagnet is in the moment of energising adhesive, and the different pole polarity of instantaneous before this generation between the contact-making surface at moving iron core and the friction support position of end cap and housing makes it to inhale and together, the generation of adhesive pressure is arranged this moment between contact-making surface.Because the existence of this adhesive pressure, skin-friction force between two relative parts on the friction pair must increase, in moving iron core adhesive moving process subsequently, generation or embedding that hard point on the two relative parts contact-making surfaces or uneven place just may have hard particles such as abrasive dust, form and embed wearing and tearing, thus the generation of accelerated wear test fluffiness between the contact-making surface of friction pair.
---and the utility model is owing to support the existence that the ceramic spraying layer is arranged between the two relative parts contact-making surface of friction pair at moving core, this just is equivalent to increase an isolation wearing layer between friction pair.Like this,, between the contact-making surface that moves core support friction pair, just do not have this to inhale and process, thereby between contact-making surface, just can not produce also pressure of suction yet in the moment of electromagnet energising adhesive.Moving iron core at this moment is the equal of that suspension is moved, thereby the possibility of hard particles such as generation or embedding abrasive dust is just minimum between the contact-making surface of two relative parts on the moving core support friction pair.Moreover the coefficient of friction between the ceramic spraying layer only has 0.12, is far smaller than 45
#The steel 0.64 mutual coefficient of friction of back that quenches, so frictional resistance is minimum, wear extent also just significantly reduces thereupon, from this respect, produces the possibility that embeds wearing and tearing during both relative motions and also just reduces greatly thereupon.Like this, the phenomenon that moving core supports wearing and tearing fluffing on the friction pair also just no longer takes place, and the danger of the moving core jam of electromagnet has not just existed yet, and therefore the safety in utilization of electromagnetic brake and elevator also just is greatly improved.
Moving core in the utility model supports the thickness of the ceramic spraying layer on the friction pair and is advisable with 0.1-0.3mm.Definite principle of this thickness is: the result learns through experiment test, and when the ceramic spraying layer thickness was 0.1mm, electromagnetic actuation power reduced 1.5-2%; When thickness was 0.2mm, electromagnetic actuation power reduced 3-4%; When thickness is 0.3mm, influence to electromagnetic actuation power is no more than 6%, and behind ceramic coated layer, the gap between moving iron core and the corresponding member supporting face can narrow down to 0.15mm, like this, the actual gap of the two is exactly 0.3mm-0.15mm=0.15mm.
As seen, this gap also just is not more than 3% to the adhesive influence power of electromagnet.Therefore, it is the actual use needs that can satisfy electromagnet fully that thickness that moving core supports the ceramic spraying layer on the friction pair is chosen between the 0.1-0.3mm, and the moving core of electromagnet supports the anti-wear performance of friction pair and can strengthen therefore and greatly.
Experimental test through elevator professional production producer, the utility model do not safeguard, under the unlubricated working condition, the safe operation number of times can reach 1000-1500 ten thousand times, can satisfy the needs of the safe operation of elevator in the main frame length of life fully.The utility model be a kind ofly exempt to disassemble, non-maintaining, non-lubricating elevator brake new electromagnet.
