According to the utility model, the depth of the annular recess is the 1/2~1/5 of the magnetic conduction ring radial thickness.
According to the utility model, insulating materials is filled in the annular recess.
According to the utility model, the minimum spacing between the two neighboring annular recess is 0.2~0.5mm.
According to the utility model, the width of the annular recess is 4~20 μm.
According to the utility model, the annular recess is molded by laser etching process.
According to the utility model, the material of the magnetic guiding loop is permeability alloys steel or ingot iron.
The utility model additionally provides a kind of magnetic suspension rotor system, including shaft and above-mentioned magnetic suspension shaft are forwarded Son, the magnetic suspension bearing rotor are set in the outside of the shaft, and the shaft is matched with the magnetic suspension bearing rotor interference It closes.
(3) advantageous effect
The above-mentioned technical proposal of the utility model has the following advantages that compared with prior art:Magnetcisuspension provided in this embodiment Floating bearing rotor magnetic guiding loop uses monolithic construction, and annular recess of the opening towards outside is provided on magnetic guiding loop, both solves Existing magnetic suspension bearing rotor of having determined uses eddy current problem caused by complete metal ring, also solves existing magnetic suspension bearing The problem of rotor is difficult to be applicable in the environment to run at high speed using lamination assembling formula structure, process and assemble is simple.In the present embodiment Magnetic guiding loop can take larger value of interference fit so that magnetic guiding loop is connect more with shaft due to structural strength height with shaft Reliably, to use the environment to run at high speed.

Fig. 2 is the structural solid for the magnetic suspension rotor system with magnetic suspension bearing that the utility model embodiment provides Figure;
Fig. 3 is the enlarged drawing at A in Fig. 2.
In figure:1:Magnetic guiding loop;2:Annular recess;3:Shaft.
Specific implementation mode
It is new below in conjunction with this practicality to keep the purpose, technical scheme and advantage of the utility model embodiment clearer Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched The embodiment stated is a part of the embodiment of the utility model, instead of all the embodiments.Based on the reality in the utility model Apply example, the every other embodiment that those of ordinary skill in the art are obtained without making creative work, all Belong to the range of the utility model protection.
As shown in Figure 1, a kind of magnetic suspension bearing rotor that the utility model embodiment provides, including monoblock type magnetic guiding loop 1, Multiple annular recess 2 are arranged at intervals with along the axial direction magnetic guiding loop 1 of the magnetic guiding loop 1, the opening of the annular recess 2 is equal Towards the outside of the magnetic guiding loop 1.Magnetic suspension bearing rotor magnetic guiding loop 1 provided in this embodiment uses monolithic construction, and It is provided with annular recess 2 of the opening towards outside on magnetic guiding loop 1, had both solved existing magnetic suspension bearing rotor using complete gold Belong to eddy current problem caused by ring, also solves existing magnetic suspension bearing rotor and be difficult to be applicable in high speed using lamination assembling formula structure The problem of environment of operating, process and assemble is simple.Magnetic guiding loop 1 in the present embodiment can be adopted due to structural strength height with shaft Take larger value of interference fit so that magnetic guiding loop 1 connect with shaft it is more reliable, to use the environment to run at high speed.
Preferably, the depth of annular recess 2 described in the present embodiment is the 1/2~1/5 of 1 radial thickness of the magnetic guiding loop. Since eddy-current loss mainly concentrates ability material surface, so smaller etching depth can effectively reduce vortex, therefore, by ring The depth of shape groove 2 is set as the 1/2~1/5 of 1 radial thickness of the magnetic guiding loop, can not only ensure to reduce vortex, but also can protect Demonstrate,prove the structural strength of magnetic guiding loop 1.
