Description
Technical field：
The present invention relates to a kind of magnetic axis bearing structure.
Background technology：
Existing magnetic axis bearing structure is commonly：Thrust magnetic bearing in magnetic bearing is distributed in one end of rotor, then two
Installed thrust disk between individual thrust magnetic bearing, when two ends of rotor needs to install acting part (as impeller) simultaneously, rotating speed and
Rotor rigidity is limited to the structure at rotor propulsion disc end.And the magnetic bearing of said structure is not easy to modularized production it is impossible to by two
The thrust magnetic bearing at end and radial direction magnetic bearing are designed to same module.
Therefore, it is necessory to improve prior art to solve the deficiency of prior art.
Content of the invention：
The present invention is to solve the problems, such as that above-mentioned prior art provides a kind of magnetic axis bearing structure.
The technical solution adopted in the present invention has：A kind of magnetic axis bearing structure, including rotor, stator, radial direction magnetic bearing and magnetic
Bearing block, described stator is fixed in magnetic axis bearing, and two radial direction magnetic bearings are symmetrically set in stator both sides, and rotor rotating support is in fixed
In son and radial direction magnetic bearing, also include thrust magnetic bearing, described in two, thrust magnetic bearing is symmetrically set in magnetic axis bearing, and thrust magnetic
Bearing is located at the outside of radial direction magnetic bearing；
Described magnetic axis bearing includes base, bearing block and fixing end cap, and bearing block described in two is fixed on the two-port of base
Place, in bearing block, two fixing end caps are fixed on bearing block and by radial direction magnetic bearing for radial direction magnetic bearing and thrust magnetic bearing
It is fixed in bearing block with thrust magnetic bearing；
Described rotor includes axle body and axle journal, is formed with the shaft shoulder between axle body and axle journal, and described radial direction magnetic bearing is sheathed on
On axle body, thrust magnetic bearing is sheathed on axle journal.
Further, described bearing block is provided with the clutch shaft bearing for fixed radial magnetic bearing and thrust magnetic bearing respectively
Hole and second bearing hole.
Further, the outer circle wall of described bearing block is provided with positioning side.
The present invention has the advantages that：
