Set, the flux sleeve end extend into the side wall of mounting portion, and it is uniform by the cooling convergent force of impeller injection molding to make bearing, and prevent
Only bearing deformation, the running balance in wheel rotation work, no bounce.
As an improvement of the above technical solution, the mounting portion is the mounting groove being arranged on tubular interconnecting piece lateral wall,
One end that the flux sleeve puts in mounting portion side wall is provided with fluid injection flow orifice, avoids flux sleeve barrier injection molding in impeller injection molding
The flowing of liquid.
Further, it there are four the fluid injection flow orifice settings, is circumferentially evenly arranged on flux sleeve.
As a further improvement of the above technical scheme, it is provided with protection steel bushing on the outside of the magnet, prevents the magnet
Cracking, guarantees its reliability of operation, while the abrasion for avoiding the magnet surface course of work from generating, and improves the longevity of vane rotor
Life.
Further, one end infolding and the magnet end face of the protection steel bushing far from impeller body cooperate.
Preferably, magnet one end is provided with radial groove, fills when being molded for impeller, and described recessed after Impeller Shaping
Slot cooperatively forms circumferential limit.
Further, the magnet is arranged with respect to step surface, the groove is recessed in the middle part of the end face of impeller body in institute
It states on step surface.
Preferably, the bearing includes the bearing liner at both ends and the metal-coating at middle part, is set on the outside of the bearing liner
It is equipped with clamping portion, enhances the limit fixed function of bearing and impeller.
The beneficial effects of the present invention are: a kind of high-performance vane rotor of the invention, including impeller and impeller cover, the leaf
Wheel includes the impeller body on top and the tubular interconnecting piece of lower part, and the impeller center is provided with bearing, the tubular of the impeller
It is provided with the mounting portion of annular on interconnecting piece, is provided with columnar magnet, and the mounting portion in the mounting portion of the annular
Columnar flux sleeve is provided between magnet, the flux sleeve end extends into the side wall of mounting portion, makes bearing by leaf
The cooling convergent force of wheel injection molding is uniform, and prevents bearing deformation, the running balance in wheel rotation work, no bounce.
