Abstract
The invention discloses a kind of magnetic bearing box-like skeleton, 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, magnetic bearing upper ledge is placed between inframe under box-like magnetic bearing, and magnetic bearing upper ledge and the step surface in positioning step portion and is formed with positioning chamber.Replace former magnetic bearing lower frame with box-like magnetic bearing lower frame, with the inwall positioning substitution positioning finger setting of box-like magnetic bearing lower frame.
Description
Technical field：
The present invention relates to a kind of magnetic bearing box-like skeleton.
Background technology：
Magnetic bearing is to make bearing of the rotor in suspended state using controlled magnetic field.Hanged because the rotor in magnetic bearing is in
Floating state, is not physically contacted with retaining element, therefore, it is possible to can not be high-revolving turn of load suitable for conventional scroll bearing
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 constituted；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 is easy to glance off along horizontal direction built on the sand, when being influenceed by external force.For example
Clamping is inaccurate during processing, when rocking and impact, deposit in handling process shelf level, parts do not expand with heat and contract with cold, all can
Magnetic bearing part is caused to occur sliding deformation.Because magnetic bearing is a kind of accurate electromechanical equipment, very high is required to structure precision.This
The deformation of the degree of kind frequently can lead to the performance change of magnetic bearing product, so as to destroy homogeneity of product and stability.
The content of the invention：
The present invention is to provide a kind of magnetic bearing box-like skeleton to solve the problem of above-mentioned prior art is present.
The technical solution adopted by the present invention has：A kind of magnetic bearing box-like skeleton, including magnetic bearing upper ledge and box-like magnetic bearing
Inframe is provided with positioning step portion under lower frame, the box-like magnetic bearing, and magnetic bearing upper ledge is placed in inframe under box-like magnetic bearing, and magnetic axis
Positioning chamber is formed between the step surface for holding upper ledge and 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, 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 present invention has the advantages that：
1) with the former magnetic bearing lower frame of box-like magnetic bearing lower frame substitution, 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 replaced 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 using being welded and fixed, so as to obtain higher Stability Analysis of Structures with magnetic bearing upper ledge
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 structure chart of the present invention.
Fig. 2 is application structure figure of the present invention.
Embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the present invention discloses a kind of magnetic bearing box-like skeleton, including magnetic bearing upper ledge 11 and box-like magnetic
Positioning step portion 120 is provided with bearing lower frame 12, box-like magnetic bearing lower frame 12, magnetic bearing upper ledge 11 is placed in box-like magnetic bearing lower frame
Positioning chamber 122 is formed with 12, and between magnetic bearing upper ledge 11 and the step surface in positioning step portion 120.In magnetic bearing upper ledge 11
The first screw hole 111 is provided with, the second screw hole 121, first spiral shell are provided with the step surface of box-like magnetic bearing lower frame 12
The screw hole 121 of nail 111 and second connects.
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 present invention constrains the water of magnetic pole silicon steel sheet 500 and magnetic bearing upper ledge 11 using inwall
It is smooth to move, it instead of the horizontal location effect of alignment pin.
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 entirely the shape stability of magnetic bearing part is just guaranteed, and will not become in manufacture, storage and use
Shape.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made under the premise without departing from the principles of the invention, and these improvement also should be regarded as the present invention's
Protection domain.
