Problems solved by technology

[0002] At present, in the magnetic levitation centrifugal blower and air suspension centrifugal blower, the connection method between the diversion cone and the rotor is usually threaded connection. The threaded connection method requires high machining accuracy of the thread. When the thread at the lower part of the diversion cone is connected to the rotor thread, It is necessary to use a wrench to tighten the diversion cone, so the outer hexagon is processed on it, which will have a greater impact on the airflow and is not conducive to the flow of airflow
At the same time, 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 accuracy of the tightening torque will also be affected

Embodiment Construction

[0023] Please refer to Figure 1 to Figure 7 As shown, the air guide impeller assembly of the centrifugal blower of the present invention includes a rotor 1; an impeller 2 mounted on the rotor 1; a circlip 3 mounted on the upper surface of the impeller 2; Gasket 4; compression bolt 5; weight screw 6 and shroud 7.

[0024] The central shaft hole of the impeller 2 is matched with the rotor 1, wherein the central shaft hole of the impeller 2 is aligned with the rotor shaft, the impeller 2 is installed in the direction of the rotor 1, and then the impeller 2 is installed and fixed on the rotor 1 through the key 8. The upper end surface of the impeller 2 is recessed downward along the diameter direction to form a first notch 20 that divides the upper end surface of the impeller 2 into two parts, and a number of counterweight screw holes extending in the vertical direction are formed at even intervals on the two parts twenty one. The snap spring 3 includes a disc-shaped main body ...

Abstract

The invention discloses a wind guide impeller assembly of a centrifugal blower. The impeller is pressed tightly through threaded connection of compression bolts and a rotor, pressing force can be adjusted to designed pressing force, bending parts bent upwards of lock washers stop the compression bolts from rotating, an anti-rotating function is performed, due to the fact that the lock washers are circular, the lock washers can be bent up at any direction and be free of influences of positions and directions, then after an air guide sleeve covers a structure assembled by the compression bolts, the lock washers and clamp springs, the rotation of the air guide sleeve is restrained through the matching of a lug formed on the air guide sleeve and a first notch, and the motion of the air guide sleeve in the vertical direction is restrained through matching of a window formed in the air guide sleeve and a buckling part. The wind guide impeller assembly of the centrifugal blower has the advantages of being good in anti-loose effect, good in air suction effect and the like.

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 diversion cone and the rotor is usually threaded connection. The thread connection method requires high machining accuracy of the thread. When the thread at the lower part of the diversion cone is connected to the rotor thread, You need to use a wrench to tighten the diversion cone, so there is an outer hexagon on it, which will have a greater impact on the airflow and is not conducive to the flow of airflow. At the same time, the existing threaded connection achieves the purpose of anti-loosening of the thread by applying glue to the thread, but the glue will affect the disassembly, and the accuracy of the tightening torque will also be affected. [0003] The...
