Air guide impeller assembly of centrifugal blower

Abstract

The invention discloses an air guide impeller assembly of a centrifugal blower, and belongs to the technical field of machinery. The air guide impeller assembly comprises a rotor, an impeller, a diversion cone, a counterweight screw and a locking gasket, wherein the impeller, the diversion cone and the counterweight screw are arranged on the rotor; the locking gasket is arranged on the upper surface of the impeller; the upper end surface of the impeller is sunken to form counterweight screw holes; a through hole which penetrates through the upper surface and the lower surface of the locking gasket is formed in the central position of the locking gasket and is communicated with a central axis hole of the impeller in the longitudinal direction; bending hooks in the counterweight screw holes and teeth which are separated from the bending hooks are arranged on the outer edge of the locking gasket; the diversion cone comprises a round rod part and a cone head, the round rod part is in threaded connection with the rotor after passing through the through hole of the locking gasket and the central axis hole of the impeller, and the cone head is positioned on the locking gasket; a plurality of gaps are formed in the lower edge of the cone head; the teeth are clamped in the gaps. According to the air guide impeller assembly of the centrifugal blower, the loosening of the diversion cone is inhibited effectively so that an effect of preventing loosening is achieved.

Description

Technical field: [0001] The invention relates to an air guiding impeller assembly of a centrifugal blower, which belongs to the technical field of machinery. Background technique: [0002] At present, in the magnetic levitation centrifugal blower and air suspension centrifugal blower, the connection method between the guide cone and the rotor is usually threaded connection, and the existing threaded connection achieves the purpose of anti-loosening by applying glue to the thread, but the glue will affect the disassembly. And the tightening torque accuracy will also be affected. [0003] Therefore, it is necessary to improve the prior art to solve the deficiencies of the prior art. Invention content: [0004] The object of the present invention is to address the deficiencies of the prior art and provide a centrifugal blower air guide impeller assembly, which has the advantages of convenient disassembly, good anti-loosening effect and high impeller strength. [0005] The p...
