Abstract
The utility model provides a magnetic damper magnet steel forever, including fan -shaped alnico body, the quantity of fan -shaped alnico body is 6, and the sizes are the same, become the hollow cylinder of cross -section for the ring after bonding together, it has the hoop to paste on one side of hollow cylinder, the hoop is unanimous with the hollow cylinder cross sectional shape, there is the counter bore on the fan -shaped alnico body, have on the hoop with counter bore complex hole, screw fixed connection to the position that needs the assembly is passed through in counter bore and hole, above -mentioned structure can improve magnetic damper magnet steel forever's processing qualification rate and assembly qualification rate.
Description
Technical field
The utility model relates to Al-Ni-Co permanent magnet technical field, more particularly, relates to a kind of permanent-magnet damper magnet steel.
Background technology
In prior art, the permanent-magnet damper magnet steel on magnetic shaft coupling is the overall structure of disc-shape, and because its external diameter is comparatively large, thinner thickness, cracking easily appears in product in process of production, and qualification rate is very low.
So how to provide a kind of novel permanent-magnet damper magnet steel, make it easily process in process of production, do not ftracture, improving conforming product rate is current those skilled in the art's problem demanding prompt solution.
Utility model content
In view of this, the utility model provides a kind of permanent-magnet damper magnet steel, and solve deficiency of the prior art, concrete scheme is as follows:
A kind of permanent-magnet damper magnet steel, comprises fan-shaped alnico magnet body, it is characterized in that:
The quantity of described fan-shaped alnico magnet body is 6, measure-alike, becomes the hollow cylinder that cross section is annulus after bonding together;
Described hollow cylinder side is pasted with iron hoop, and described iron hoop is consistent with described hollow cylinder cross sectional shape;
Described fan-shaped alnico magnet body has counterbore, described iron hoop has the hole coordinated with described counterbore, described counterbore and described hole are fixedly attached to the position needing assembling by screw.
Preferably, between described fan-shaped alnico magnet body and to adopt epoxy glue to paste between hollow cylinder and iron hoop fixing.
Preferably, the thickness of described iron hoop is 2mm, and the described fan-shaped alnico magnet body trade mark is LNG13.
The permanent-magnet damper magnet steel that the utility model provides, when keeping product design size constancy, original magnet steel body is changed into 6 pieces of fan-shaped alnico magnet bodies are bonding to be formed, single fan-shaped alnico magnet body is little compared with original magnet steel bulk volume, easy to process, there will not be problems of crack aborning, simultaneously iron hoop be set in side, assembling is more prone to, safety.Reach the beneficial effect improving conforming product rate and assembly qualified rate.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to accompanying drawing required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the front view of permanent-magnet damper magnet steel;
Fig. 2 is the half sectional view of permanent-magnet damper magnet steel;
In figure: 1, fan-shaped alnico magnet body 2, iron hoop 3, counterbore 4, hole 5, hollow cylinder
Embodiment
The utility model provides a kind of permanent-magnet damper magnet steel, reaches the beneficial effect improving conforming product rate and assembly qualified rate.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 and Fig. 2 is same embodiment of the present utility model, and Fig. 1 is the front view of permanent-magnet damper magnet steel, and Fig. 2 is the half sectional view of permanent-magnet damper magnet steel.The permanent-magnet damper magnet steel that the present embodiment provides comprises fan-shaped alnico magnet body 1, the quantity of fan-shaped alnico magnet body 1 is 6, measure-alike, the hollow cylinder 5 that cross section is annulus is become after bonding together, be pasted with iron hoop 2 in hollow cylinder 5 side, iron hoop 2 is consistent with hollow cylinder 5 cross sectional shape, and fan-shaped alnico magnet body 1 has counterbore 3, iron hoop 2 has the hole 4 coordinated with counterbore 3, counterbore 3 and hole 4 are fixedly attached to the position needing assembling by screw.
The permanent-magnet damper magnet steel that the present embodiment provides is when keeping product design size constancy, original magnet steel body is changed into 6 pieces of fan-shaped alnico magnet bodies 1 are bonding to be formed, single fan-shaped alnico magnet body 1 is little compared with original magnet steel bulk volume, easy to process, there will not be problems of crack aborning, product qualified rate improves, iron hoop 2 is being set due to side simultaneously, iron hoop 2 intensity and Toughness Ratio magnet steel itself exceed a lot, can not break in assembling process, thus also greatly reduce assembly difficulty, improve assembly yield.
Preferred as the present embodiment, can adopt epoxy glue to paste fixing between fan-shaped alnico magnet body 1 and between hollow cylinder 5 and iron hoop 2.
Preferred as another of the present embodiment, the thickness of iron hoop 2 is 2mm, and fan-shaped alnico magnet body 1 trade mark is LNG13.When such configuration can ensure that permanent-magnet damper magnet steel volume reduces, magnetic property is constant.
