Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
With reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu is fully described by, it is clear that described embodiment is a part of the embodiment of the utility model, rather than whole implementation
Example.Based on the only embodiment in the utility model, those skilled in the art are obtained without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Many details are elaborated in the following description in order to fully understand the utility model, but this practicality is new
Type can also be implemented using other different from other manner described here, and those skilled in the art can be without prejudice to this reality
With doing similar popularization in the case of novel intension, therefore the utility model is not limited by following public specific embodiment.
As shown in Figure 1, the bilobed wheel pull rod permanent magnet rotor structure for air suspension centrifugal blower, including rotor
Coaxially it is placed in the impeller 2 at rotor both ends.Rotor is in split structure, including permanent magnetism core 11, pull rod 12, packet
Sheath 13, the rotor spindle nose 142 set on 13 both ends of sheath for being overlying on 11 lateral wall of permanent magnetism core；Rotor spindle nose, including coaxial sleeve
The closure 141 connect and spindle nose 142, it is described to block 141 both ends for being embedded at sheath 13, it is interference fitted with sheath 13, centre bit
It sets and is outward extended with boss, and the center perforation of closure 141 offers threaded hole, the spindle nose 142 is movably set in this
On boss, the spindle nose 142 is in the hierarchic structure of ecto-entad increasing diameter, and inner side end fits with 141 outsides are blocked；
Pull rod 12, one end are stretched into threaded hole and are threadedly coupled with it, and the other end screw-thread fit of pull rod 12 has locking nut 15；Impeller
2, it is actively located on pull rod 12, and be socketed with the outer end of spindle nose 142, the outer end face of the impeller 2 is interior with locking nut 15
Side fits；The pull rod 12 of one side is equipped with thrust disc 3, and the thrust disc 3 is movably set in the outer end of spindle nose 142, juxtaposition
At the annular groove that 2 inner face of impeller and 142 cascaded surface of spindle nose are formed；The pull rod 12 of the other side is equipped with air-cooled impeller 4, the wind
Cold impeller 4 is movably set in the outer end of spindle nose 142, is placed at the annular groove that 2 inner face of impeller is formed with 142 cascaded surface of spindle nose.
The rotor structure uses split type assembling, and pull rod 12 and rotor are split, and reduces rotor entirety
Axial length, easy to process and coaxiality error is small, and the two is convenient for disassembly and assembly using threaded connection；Also, the structure is by armature spindle
Head splits into closure 141 and the spindle nose 142 of socket, is interference fitted with it wherein blocking 141 insertion rotors so that motor turns
Son itself ensure its bonding strength under the premise of, greatly reduce the weight of rotor main body, while solving armature spindle
The difficult replacement problem of head abrasion.
Apply big pretightning force to locking nut 15 after assembling to lock, since each component of the structure is coordinated using small―gap suture,
It easily facilitates whole preload to fix, to ensure whole bonding strength, and ensure that the vertical requirement of thrust disc 3.
Since existing label type p-m rotor mostly uses greatly the tile permanent magnet of piecemeal, installing cooperation with rotor mandrel needs
Set suitable fit clearance, it is complicated, and magnet demagnetizes in use for some time the phenomenon that, cause motor
The low problem of fever, efficiency.In the case where the structure uses split type (splitting rotor mandrel), to avoid the above problem
Generation, the working efficiency of motor is improved, so the entity structure that the permanent magnetism core 11 is cylinder, it is preferred to use samarium cobalt permanent magnet
Body.
Wherein, to ensure the whole concentricity of the rotor structure, between impeller 2 and spindle nose 142, thrust disc 3 and spindle nose 142
Between, between air-cooled impeller 4 and spindle nose 142, spindle nose 142 and between blocking 141, between spindle nose 142 and pull rod 12 and impeller
Activity fit clearance between 2 and pull rod 12 is 0.02~0.03mm.
To ensure the integral strength and rigidity of the rotor structure, preferred pull rod 12 is nickel base superalloy material, and is sealed
Stifled 141 is identical with the material of spindle nose 142, is titanium alloy material.
Also, to ensure the rotor structure when rotating at high speed, pull rod 12 does not generate loosening, and locking screw with blocking 141
Mother 15 is always maintained at coupling mechanism force, so two thread rotary orientations for blocking the threaded hole on 141 are on the contrary, on the locking nut 15
Hand of spiral is identical as the thread rotary orientation of homonymy threaded hole.
It the above is only the preferred embodiment of the utility model, anyone content according to the present utility model is to the utility model
A little simple modification, deformation and the equivalent replacement made each falls within the scope of protection of the utility model.
