Abstract
The utility model relates to a moving-core abrasion-free double-push electromagnet. The structure of the double-push electromagnet is as follows: two opposite moving cores and two coil windings are arranged in a shell; outer supporting shafts of the two moving cores pass through a central hole of a shell end cover; an inside separating layer is arranged at the middle part of the shell; and a shaft supporting mechanism is arranged between the inside separating layer of the shell and the inner end faces of the moving cores. As the double-push electromagnet has a double-support structure, i.e., two ends of each moving core are supported by the supporting shafts, the moving cores can be suspended in an inner cavity of the shell but not in contact friction with the surface of the inner cavity of the shell; therefore, friction and fluffing of the moving cores can be prevented, the blockage of the moving cores is avoided, and the use safety of an elevator brake is improved.
Description
Technical field
But the utility model relates to the electromagnet that a kind of armature straight line moves, and specifically a kind of moving core does not have wearing and tearing formula dual-push electromagnetic iron.
Background technology
The structure of existing dual-push electromagnetic iron is that two relative moving cores and two coil windings are housed in housing, and the outer back shaft of two moving cores passes the centre bore of housing end plug, and the medial end of two moving cores is supported in the housing inner chamber.In order not influence magnetic conductive loop and can to produce a bigger electromagnetism motive force, the moving core multiselect of dual-push electromagnetic iron is made with pure iron or the good mild steel of magnetic conductivity.Because these metal materials can not be done the Quenching Treatment of sclerosis, the resistance to wear of therefore moving core is not high.Elevator is in long-term operation, braking procedure, and the moving core of electromagnet supports friction pair will produce wearing and tearing because of friction, thereby forms the rough surface fluffing, and severe patient will produce moving core jam phenomenon, makes misfunctioning of brake, causes serious consequence.Therefore, the wear problem of the moving core of dual-push electromagnetic iron has become a big difficult point and the focus that elevator brake is manufactured industry.
The utility model content
The purpose of this utility model just provides a kind of moving core does not have wearing and tearing formula dual-push electromagnetic iron, to improve the safety in utilization of elevator brake.
The utility model is achieved in that a kind of moving core does not have wearing and tearing formula dual-push electromagnetic iron, two relative moving cores and two coil windings are housed in housing, the outer back shaft of two moving cores passes the centre bore of housing end plug, be provided with internal portioning layer at described housing middle part, between the inner face of housing internal portioning layer and described moving core, be provided with a supporting mechanism.
A kind of supporting mechanism is to be provided with outrigger shaft at described housing internal portioning layer center, has endoporus on the inner face of described moving core, and the two ends of described outrigger shaft are plugged on respectively in the described endoporus of described two moving cores.
An another kind of axle supporting mechanism is to have centre bore on described housing internal portioning layer, is shaped on mandrel at the inner face of described two moving cores, and described mandrel is plugged in the described centre bore of described housing internal portioning layer.
Key points in design of the present utility model is exactly to support moving core body in the inboard of dual-push electromagnetic iron two moving cores by a supporting mechanism is set, make the dual-support structure that a kind of moving core two ends all have back shaft to support thus, this does not contact with the surface of internal cavity of housing with regard to making moving core be suspended in the housing inner chamber.Like this, when work of electromagnet, moving core just can not rubbed, thereby has just stopped the wearing and tearing fluffing of moving core yet, has avoided moving core jam phenomenon, has improved the safety in utilization of elevator brake.
Description of drawings
Fig. 1, Fig. 2 are the structural representations of two embodiment of the utility model.
Embodiment
Embodiment 1:
As shown in Figure 1, housing 1 of the present utility model is cylindric, and its middle part is provided with internal portioning layer; Be sealed with end cap 5 at the two ends of housing 1, two coil windings 3 moving core 2 relative with two is housed in the inner chamber of housing 1; The outer back shaft 4 of moving core 2 passes the centre bore of end cap 5; Be provided with the outrigger shaft 6 that stretches out to the both sides cavity at the center of housing internal portioning layer, have endoporus 7 on the inner face of two moving cores 2, the two ends of outrigger shaft 6 are plugged on respectively in the endoporus of these two moving cores.The grafting of the outrigger shaft 6 in the endoporus 7 on the moving core 2 and the housing internal portioning layer cooperates, and has constituted the supporting mechanism on moving core 2 inner faces.And the sliding support contact-making surface of the endoporus 7 of the sliding support contact-making surface of the outer back shaft 4 of moving core and end cap central bore and moving core and outrigger shaft 6 has constituted two moving cores support friction pairs of this kind dual-push electromagnetic iron respectively.
The utility model is shaped on the ceramic spraying layer on the support friction pair of described axle supporting mechanism.Described ceramic spraying layer is the method with thermal spraying, and under the high temperature melt state, high velocity jet is on the surface at the sliding friction position of described axle supporting mechanism with engineering ceramic material.
Owing to the high-wearing feature of ceramic spraying layer, can only the ceramic spraying layer be produced on the surface at the sliding friction position of the axle supporting mechanism that moves core 2; Also can only the ceramic spraying layer be produced on the surface of the outrigger shaft 6 of housing internal portioning layer; Also the ceramic spraying layer can be produced on the inner surface of the described endoporus 7 of described axle supporting mechanism.
Support two of friction pair at moving core and connect to touch on one of them parts in the parts and make the ceramic spraying layer, its advantage is to reduce the cost of manufacture of ceramic spraying layer.For guaranteeing the high reliability of electromagnet, can all make the ceramic spraying layer on the surface of the sliding friction pair that moves the core two ends, make these positions have very high resistance to wear and self lubricity.
The utility model also can be installed wear ring 10 in the described endoporus 7 of described axle supporting mechanism.Adopt this form also can improve the resistance to wear of a supporting mechanism.
