Description
Technical field：
The utility model is related to a kind of magnetic suspension cfentrifugal blower structure.
Background technology：
Existing magnetic suspension cfentrifugal blower complex structure, is not easy to assembling.Magnet steel on rotor is by alloy protective
Set is fixed, and when alloy sleeve in variation magnetic field while rotating (rotor), the induced-current that inside produces can bring energy loss (i.e.
Eddy-current loss), it is that the heat-radiation belt of motor carrys out difficulty.And alloy sleeve due to be elastic conjunction, it is necessary to after being heated hot jacket in
On rotor, the improper risk for magnet steel is faced high temperature loss of excitation of selection of too high sheath temperature or the magnet steel trade mark, according to plus
The supplementary means of prompt drop temperature, sheath face again crack loss intensity risk, and alloy sleeve be set in rotor it
Afterwards, in addition it is also necessary to carry out follow-up outer surface processing, rotor now can produce shadow because there is magnetic to follow-up operation
Ring, such as influence machine finish, inconvenience measurement size etc..
Therefore, it is necessory to be improved to solve the deficiency of prior art to prior art.
Utility model content：
The utility model is to provide a kind of magnetcisuspension floating centrifugal air blast to solve the problems, such as above-mentioned prior art
Machine structure.
The technical scheme that the utility model is used has：A kind of magnetic suspension cfentrifugal blower structure, including it is casing, fixed
Son, rotor, magnet steel, magnetic bearing, bearing block, stator fixed block and carbon fiber wire, bearing block described in two are fixed on a left side for casing
Right both sides, magnetic bearing is fixed in bearing block, and stator is fixed in casing by stator fixed block, and rotor rotating support is in stator
In magnetic bearing, and the two ends of rotor are stretched in outside bearing block, and on the outer wall of rotor, carbon fiber wire is set around rotor to magnet steel
In circumferential wall and sheath is formed, magnet steel is fixed on the outer wall of rotor by the sheath.
Further, the inwall of the casing is provided with step surface for carrying out axially position to stator and for fixed
Sub- fixed block carries out the groove of axial limiting.
Further, the stator fixed block is provided with four pieces, is uniformly distributed along the circumferencial direction of rotor, stator fixed block with
It is connected by screw between stator.
The utility model has the advantages that：
1) the utility model simple structure, assembling is easy, using the set magnet permanent body in carbon fiber sheath protection rotor, protects
Eddy-current loss is reduced while card intensity；
2) rotor can be by all dimensioneds in place before permanent magnet is installed, and mounting magnetic steel completion carries out carbon fiber and twines
It is offline by rotor around rear, in the absence of subsequent handling；
3) the step of not having high-temperature operation, will not produce loss of excitation risk.
Brief description of the drawings：
Fig. 1 is the utility model structure chart.
Specific embodiment：
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of magnetic suspension cfentrifugal blower structure of the utility model, including casing 1, stator 2, rotor 3,
Magnet steel 4, magnetic bearing 5, bearing block 6, stator fixed block 7 and carbon fiber wire, two bearings seat 6 are fixed on the left and right sides of casing 1,
Magnetic bearing 5 is fixed in bearing block 6, and stator 2 is fixed in casing 1 by stator fixed block 7, and the rotating support of rotor 3 is in stator 2
In magnetic bearing 5, and the two ends of rotor 3 are stretched in outside bearing block 6, and on the outer wall of rotor 3, carbon fiber wire is set around magnet steel 4
In the circumferential wall of rotor 3 and sheath 8 is formed, magnet steel 4 is stated sheath 8 and is fixed on the outer wall of rotor 3 by this.
Carbon fiber wire in the utility model can impose pretightning force in winding on carbon fiber wire, thus offset magnet steel 4 and exist
The centrifugal force produced in the course of work of rotor 3, filament imposes pretightning force and does not need hot conditions, therefore magnet steel 4 without loss of excitation
Risk.
For ease of stator 2 is fixed in casing 1, it is provided with the inwall of casing 1 for carrying out axially position to stator 2
Step surface 11 and the groove 12 for carrying out axial limiting to stator fixed block 7.
Stator fixed block 7 is provided with four pieces, is uniformly distributed along the circumferencial direction of rotor 3, between stator fixed block 7 and stator 2
It is connected by screw.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, some improvement can also be made on the premise of the utility model principle is not departed from, these improvement also should be regarded as
Protection domain of the present utility model.
