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 single impeller pull rod permanent magnet rotor structure for air suspension centrifugal blower, including rotor
Coaxially it is placed in the impeller 2 of rotor one end；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；Permanent magnetism core 11, it is cylinder
Entity structure, it is preferred to use samarium cobalt permanent magnet body；Rotor spindle nose, including the closure 141 being coaxially socketed and spindle nose 142, the envelope
Stifled 141 are embedded at the both ends of sheath 13 and the interference fit of sheath 13, and center is outward extended with boss, and blocks 141
Center perforation offers threaded hole, and the spindle nose 142 is movably set on the boss, and the spindle nose 142 is in ecto-entad
The hierarchic structure of increasing diameter, inner side end fit with 141 outsides are blocked；Pull rod 12, including symmetrically arranged two,
One end is stretched into threaded hole and is threadedly coupled with it, and the other end screw-thread fit of pull rod 12 has locking nut 15；Impeller 2, activity is worn
It is socketed on the pull rod 12 of one end, and with the outer end of the spindle nose at the end 142, inner face and 142 ladder of spindle nose of the impeller 2
Face forms annular groove, and movable sleeve is equipped with thrust disc 3 in the annular groove, and the inside of the outer end face and locking nut 15 of the impeller 2 is affixed
It closes；The pull rod 12 of the other side is equipped with air-cooled impeller 4, and the air-cooled impeller 4 is movably set in the outer end of the spindle nose 142 at the end,
