Extensive use has been obtained in the development of high-energy permanent magnet, magneto.
Currently, the alinco assembled mode of magneto is mainly embedded or two kinds of surface-mount type.Magneto is generally by magnetic
Steel is on rotor, and embedded structural shape is that rotor punching punching has magnetic slot, and magnet steel is in slot, the structural type of surface-mount type
Formula is to be sticked to magnet steel in magnetic yoke with special bonding agent.To meet the high-effect of magneto, magnetic steel material is using neodymium
Iron boron, such material are that a kind of magnetic force is very strong but frangible material.It is numerous in motor pole number, distance between magnet steel and magnet steel
In lesser situation (1 ~ 2mm of interval), embedded mounting magnetic steel not only it be not available but also be not available press strip compression magnet steel.
Utility model content
The purpose of this utility model is intended to overcome the shortcomings of the prior art, provides a kind of assemble simply and easily
The compressing structure of rotor magnetic steel.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions:
A kind of compressing structure of rotor magnetic steel, including motor shaft, the magnetic yoke being set on motor shaft, several magnet steel, bolt
Component, the first end pressure block, the second end pressure block and without latitude band；First end pressure block is arranged on motor shaft and is located at magnetic yoke
Side, second end pressure block are arranged on motor shaft and are located at the magnetic yoke other side；First end pressure block and the second end pressure block
It is connected respectively by bolt assembly and magnetic yoke；The magnet steel is alternately adhered in magnetic yoke outer rim by the pole N, S, and the both ends of magnet steel point
It is not contacted with the first end pressure block and the second end pressure block；The magnet steel is wrapped up with the contact position of the first end pressure block and the second end pressure block
Without latitude band；The gap location of adjacent magnet steel is filled with fixed glue.
Preferably, the bolt assembly includes bolt, plain cushion and spring washe.
Preferably, the magnet steel is adhered in magnetic yoke using anaerobic adhesive.
Compared with prior art, the utility model has the advantages that
The assembly of the utility model rotor simply, conveniently, is not required to other additional complicated fixed forms, can guarantee magnet steel
It will not loosen and slide, it is ensured that long-term normal, reliable, safety the operation of motor.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the cross-sectional view of the A-A along Fig. 1.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are under that premise of not paying creative labor
Every other embodiment obtained, fall within the protection scope of the utility model.In the following description, in order to clearly demonstrate originally
The structure and working method of utility model will be described on the basis of attached drawing by many Directional words, but should be incited somebody to action
The Word Understandings such as "front", "rear", "left", "right", "upper", "lower" are not construed as word of limitation for convenience of term.
The compressing structure of rotor magnetic steel shown in Fig. 1-2, including motor shaft 1, the magnetic yoke 2 being set on motor shaft 1, several magnetic
Steel 8, bolt assembly, the first end pressure block 6, the second end pressure block 11 and without latitude band 7；First end pressure block 6 is arranged in motor shaft 1
Above and it is located at 2 side of magnetic yoke, second end pressure block 11 is arranged on motor shaft 1 and is located at 2 other side of magnetic yoke；Described first
End pressure block 6 and the second end pressure block 11 are connected by bolt assembly and magnetic yoke 2 respectively；The magnet steel 8 is alternately adhered to magnetic by the pole N, S
In 2 outer rim of yoke, and the both ends of magnet steel 8 are contacted with the first end pressure block 6 and the second end pressure block 11 respectively；The magnet steel 8 and first end
It wraps up without latitude band 7 contact position of briquetting 6 and the second end pressure block 11；The gap location of adjacent magnet steel 8 is filled with fixed glue 10.
Particularly, the bolt assembly includes bolt 3, plain cushion 4 and spring washer 5.Obvious bolt assembly can also take other
Common bolt assembly.The magnet steel 8 is preferably adhered in magnetic yoke 2 using anaerobic adhesive 9, it is clear that other common liquid can also be used
Body glue.
Assembling mode is as follows:
Step 1: first will be fixed on magnetic yoke set to motor shaft, then the first end pressure block, the other end are loaded onto one end of magnetic yoke
Load onto magnet steel installation tooling.
Step 2: the faying face of all magnet steel and magnetic yoke is coated by N after anaerobic adhesive, the pole S alternately cements in yoke surfaces
On, after magnet steel installs, magnet steel installation tooling is removed, the second end pressure block is changed into and loads onto.
Step 3: it is filled in the fixed glue of the gap location of magnet steel and magnet steel, then hot setting.
Step 4: playing no latitude band after magnet steel and end pressure block assembly in the annular groove that is formed, no latitude band around to magnet steel periphery
Concordantly, magnet steel is firmly strapped in magnetic yoke.
Magnet steel, which passes through, uses anaerobic adhesive gluing, is filled at gap and with fixed glue through hot setting, both ends end pressure block pressure
Tightly, then strapped at the both ends of magnet steel with no latitude band again, magnet steel is allowed in this way and magnetic yoke forms an entirety, it is ensured that motor
Magnet steel will not loose or dislocation when longtime running.
In manufacture course of products, without considering punching die and special machining tooling, it need to only add by specific dimensions
One magnetic steel installation tooling of work, can carry out production and assembly.Molding cost is eliminated, product development cycle is shortened, is company
Benefit is created to lay a good foundation.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
