Description
Technical field：
It the utility model is related to a kind of magnetic bearing box-like skeleton.
Background technology：
Magnetic bearing is rotor is in the bearing of suspended state using controlled magnetic field.Because the rotor in magnetic bearing is in outstanding
Floating state, is not physically contacted with retaining element, thus conventional scroll bearing can be applied to can not be high-revolving turn of load
Son.
But conventional magnetic bearing field structure also has following some defects and problem：
Common magnetic axis bearing structure is：The silicon steel sheet that magnetic pole is laminated by level is formed；Wound around coil on magnetic pole；The magnetic of annular
Bearing upper ledge compresses magnetic pole silicon steel sheet with magnetic bearing lower frame；The upper and lower frame of magnetic bearing is tensed and positioned by alignment pin；Magnetic bearing
Part is arranged in bearing block by cylindrical.Because the structure of magnetic bearing part is to be passed through to determine by ring-shaped work pieces parallel from level to level
Position pin is in series, therefore structure and built on the sand, when being influenceed by external force is easy to glance off along horizontal direction.Such as
Clamping is inaccurate during processing, when rocking in handling process and impact, deposit shelf it is unhorizontal, it is parts expand with heat and contract with cold, all can
Cause magnetic bearing part that sliding deformation occurs.Because magnetic bearing is a kind of accurate electromechanical equipment, very high is required to structure precision.This
The deformation of kind degree frequently can lead to the performance change of magnetic bearing product, so as to destroy homogeneity of product and stability.
Utility model content：
The utility model is to provide a kind of magnetic bearing box-like skeleton to solve the above-mentioned problems of the prior art.
The technical solution adopted in the utility model has：A kind of magnetic bearing box-like skeleton, including magnetic bearing upper ledge and box-like magnetic
Bearing lower frame, inframe is provided with positioning step portion under the box-like magnetic bearing, and magnetic bearing upper ledge is placed in inframe under box-like magnetic bearing, and
Formed with positioning chamber between magnetic bearing upper ledge and the step surface in positioning step portion；
The magnetic bearing upper ledge is provided with the first screw hole, and the second screw is provided with the step surface of box-like magnetic bearing lower frame
Hole, first screw hole and the second screw hole connect.
Further, the magnetic bearing upper ledge is provided with the first axis hole, and box-like magnetic bearing lower frame is provided with the second axis hole, and first
Axis hole and the second axis hole are coaxial.
Further, magnetic bearing upper ledge and box-like the magnetic bearing lower frame is made of metal material.
The utility model has the advantages that：
1) former magnetic bearing lower frame is substituted with box-like magnetic bearing lower frame, with the inwall positioning substitution positioning of box-like magnetic bearing lower frame
Finger setting；
2) the more preferable box-like magnetic bearing lower frame of intensity limits the horizontal sliding of magnetic bearing part, will not manufacture, storage,
Deformed with；
3) alignment pin can be substituted with screw in box-like magnetic bearing lower frame, the processing on the single face of cylinder of inboard wall of skeleton is than multiple
Dowel hole processing is easier；
4) box-like magnetic bearing lower frame can also be used with magnetic bearing upper ledge and is welded and fixed, so as to obtain higher Stability Analysis of Structures
Property, bolt connection is omitted completely；
5) it is more firm using the magnetic axis bearing structure of box-like skeleton, therefore can be with the leaching of completely left out silicon steel sheet under certain situation
Paint, solidification, removing surface technique, so as to simplify technique, shorten man-hour, and conveniently use automatic production line.
Brief description of the drawings：
Fig. 1 is the utility model structure chart.
Fig. 2 is the utility model application structure figure.
Embodiment：
The utility model is further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the utility model discloses a kind of magnetic bearing box-like skeleton, including magnetic bearing upper ledge 11 and box
Shape magnetic bearing lower frame 12, box-like magnetic bearing lower frame 12 is interior to be provided with positioning step portion 120, and magnetic bearing upper ledge 11 is placed in box-like magnetic bearing
In lower frame 12, and formed with positioning chamber 122 between magnetic bearing upper ledge 11 and the step surface in positioning step portion 120.On magnetic bearing
Frame 11 is provided with the first screw hole 111, is provided with the second screw hole 121 on the step surface of box-like magnetic bearing lower frame 12, and described
One screw hole 111 and the second screw hole 121 connect.
The first axis hole 115 is provided with magnetic bearing upper ledge 11, box-like magnetic bearing lower frame 12 is provided with second bearing hole 125, the
One axis hole 115 and the second axis hole 125 are coaxial.
Magnetic bearing upper ledge 11 and box-like magnetic bearing lower frame 12 are made of metal material.
When in use, magnetic pole silicon steel sheet 500 is placed in positioning chamber 122, coil 400 around being located on magnetic pole silicon steel sheet 500, and
The upper end of coil 500 is stretched in the first axis hole 115, and lower end is in the stepped hole in positioning step portion 120.In magnetic bearing upper ledge
11st, screw is worn on magnetic pole silicon steel sheet 500 and box-like magnetic bearing lower frame 12.
Box-like magnetic bearing lower frame 12 in the utility model utilizes inwall constraint magnetic pole silicon steel sheet 500 and magnetic bearing upper ledge 11
Horizontal sliding, instead of alignment pin horizontal location effect.
Magnetic bearing upper ledge 11 and box-like magnetic bearing lower frame 12 are made of metal material, and intensity is not at all easy to be become
Shape, therefore the shape stability of whole magnetic bearing part is just guaranteed, and will not become in manufacture, storage and use
Shape.
Described 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
The scope of protection of the utility model.
