Abstract
The invention discloses a double-circular table magnetic bearing rotor. The double-circular table magnetic bearing rotor comprises a rotor body, and different from the prior art, the rotor body is characterized in that the bottom surfaces of two same circular tables are connected in an overlapping manner to form a double-circular table structure, an included angle between slope buses and axes of the two circular tables is alpha, and alpha is larger than or equal to 15 degrees and is smaller than or equal to 45 degrees. According to the magnetic bearing rotor, the double-circular table structure is adopted, so that radial bearing force is greatly improved, and axial and radial coupling interference is reduced.
Description
Technical field
The present invention relates to magnetic bearing part, specifically a kind of pair round platform magnetic bearing rotor.
Background technology
Magnetic bearing is to produce discontiguous controllable electric magnetic force to run on rotor using the electric current in electromagnet coil
A kind of device of spatial stability suspended state.The appearance and application of magnetic bearing, has broken many traditional ideas, result in and props up
Hold the revolution of technology.
The rotor of magnetic bearing is its rotary part, and it is for realizing turning for electric energy and mechanical energy and mechanical energy and electric energy
Changing device.The rotor of existing magnetic bearing, is mostly cylindrical structure, and it more or less has a radial direction low bearing capacity, axially and
The obvious problem of coupled interference of radial direction.
The content of the invention
The purpose of the present invention is to be directed to the deficiencies in the prior art, and provides a kind of pair of round platform magnetic bearing rotor, solves it
Radial direction low bearing capacity, the obvious problem of coupled interference axially and radially.
The present invention solves the technical scheme of its technical problem employing：
A kind of pair of round platform magnetic bearing rotor, including rotor body, unlike the prior art：The rotor body is by two
The bottom surface of individual identical round platform overlaps and connects, and forms double frustum cone structures.
The domatic bus of two round platform and the angle of axis are α, and 15 °≤α≤45 °.
There are two domatic, two two domatic difference of rotor using double frustum cone structures in the magnetic bearing rotor of the present invention
By from outer ring（That is relative stator）Magnetic force affect, make two magnetic force constitute a pair of equilibrant force, be effectively improved rotor
Radial direction bearing capacity.Compare with the rotor of traditional cylindrical structure, rotor of the present invention by magnetic surface（I.e. round platform is domatic）For oblique
Face, reduces well coupled interference axially and radially.
Description of the drawings
Fig. 1 is the stereogram of double round platform magnetic bearing rotors of the invention；
Fig. 2 is the front view of double round platform magnetic bearing rotors of the invention.
In figure, the 1. axis of 2. first round platform of rotor body, 3. first 4. domatic bus of round platform 5..
Specific embodiment
Present invention is described in further detail with reference to the accompanying drawings and examples, but is not the limit to the present invention
It is fixed.
Embodiment
With reference to Fig. 1-2, a kind of pair of round platform magnetic bearing rotor, including rotor body 1, the rotor body 1 is by two
The bottom surface of identical the first round platform 2 and the second round platform 3 overlaps and connects, and forms double frustum cone structures.
The domatic bus 4 of the round platform 3 of first round platform 2 and second and the angle of axis 5 are α, and 15 °≤α≤45 °, this
Example is 45 °.
Claims (2)
1. a kind of pair of round platform magnetic bearing rotor, including rotor body, it is characterised in that：The rotor body is identical by two
The bottom surface of round platform overlap connection, form double frustum cone structures.
2. according to claim 1 pair of round platform magnetic bearing rotor, it is characterised in that：The domatic bus of two round platform and
The angle of axis is α, and 15 °≤α≤45 °.
