Technical field
The present invention relates to magnetic suspension bearing processing technique field, is sealed more particularly to magnetic suspension bearing stator module
Gluing method, sealing frock and magnetic suspension bearing.
Background technology
As shown in Figure 1 to Figure 4, existing radial magnetic bearing stator module 100 includes magnet steel 1, fixed mount component 200, radial direction
Ring 4, iron core 5 and coil 6, fixed mount component include magnet steel fixed mount 2 and baffle plate 3.During assembling, first by coil 6 around iron core 5
On, then heating radial direction ring 4 makes its expansion, then being filled in around the iron core 5 for making coil 6 in radial direction ring 4, is soaked after its cooling
Paint, air-dry.Now by magnet steel fixed mount 2 by being screw fastening on baffle plate 3, then eight blocks of magnet steel 1 are passed through by design direction
Magnetic-adsorption positions on baffle plate 3 and by magnet steel fixed mount 2.Then, will by special tooling while axiality is ensured
Magnet steel and fixed mount component are slowly fitted on the radial direction ring 4 that dipping lacquer is air-dried, complete assembling.Due in this course,
Magnet steel 1 only completes positioning, fastening and connection by magnetic force, and in assembling process, due to the relatively high magnetism of magnet steel 1, inevitably
In the presence of vibrations and impact, so often occurring the phenomenon that magnet steel 1 is deviate from or is subjected to displacement in the fabrication process, and once there is class
Like situation, due to having assembled, the gap of retention is too small, and is influenceed by other magnetic fields of magnet steel 1, it is more difficult to by abjection or occurs
The magnet steel 1 of displacement playbacks, so as to have a strong impact on the assembly precision of radial magnetic bearing and manufacture efficiency.And on axial direction
It should not use and mechanically connect, otherwise may damage magnet steel by pressure or new positioning and assembly problem occur.

Embodiment
Although magnet steel in the prior art as described in the background art can rely on magnetic-adsorption on retainer, because
Shock and vibration during for stator module is installed into application component inevitably be present, often occur magnet steel come off or
By the winged phenomenon of shake, and rethink a magnet steel slices and put back to, due to remaining in other magnet steel magnetic force inside stator module
Influence, it is very difficult to precisely put back to original position, seriously reduce production efficiency and the accuracy of manufacture.And if using the side of mechanical position limitation instead
Method will increase the complexity of structure, and new positioning and assembly problem occurs.
Therefore in order to preferably fix magnet steel, such as Fig. 5 to Fig. 7, propose that a kind of magnetic suspension bearing is determined in the embodiment of the present invention
Sub-component glue sealing method, comprises the following steps：
A, after assembling stator module, stator module is installed in a sealing frock, and the outer round surface and envelope of stator module
Injecting glue space 10 is formed between glue frock；
B, after installing stator module, glue is injected into injecting glue space 10;
C, after injecting glue, the sealing frock equipped with stator module is heated so that glue solidifies and is coated on stator pack
On the outer round surface of part.Solid gum can be coated on the outer round surface of stator module by above step, so can be more
Magnet steel is firmly fixed, avoids the phenomenon for occurring magnet steel abjection in the fabrication process or being subjected to displacement, ensure that magnetic suspension shaft
The assembly precision and manufacture efficiency held.
In addition, in stepb, glue can also fill the gap inside stator module（Here the gap inside stator module
Including the magnet steel gap between magnet steel fixed mount, baffle plate, radial direction ring, the gap between iron core and radial direction ring, and line respectively
Gap between circle and iron core）, so in step c, can also cause the glue in the gap inside stator module to solidify.So
Solid gum is filled up by being coated on the outer round surface of stator module in the gap inside solid gum, and stator module, is improved
The manufacture stability of magnetic suspension bearing product.
Above-mentioned glue sealing method is described in detail below：
In step a, the step that stator module is installed in sealing frock includes：
A1, stator module is placed in the frock radial direction ring 7 of sealing frock；
