Problems solved by technology

[0010] The existing angle adjustment method not only needs extra clips to assist, but also the above installation method is more complicated, and the blade angle adjustment time is relatively long, resulting in low work efficiency
[0011] In the prior art, the blades are installed in the hub, which is easy to move, especially the cylindrical petiole, after long-term use, it is easy to move in the hub, reducing the efficiency

Embodiment 1

[0051] Refer to attached Figure 1-3 As shown, a new type of impeller provided by the present invention includes several blades 1 and a hub 2, and several blades 1 are uniformly installed on the hub 2; An installation groove, the blade 1 is installed in the hub 2 through the installation groove;

[0052] Refer to attached Figure 4 As shown, wherein, the blade 1 includes a blade surface 101 and a petiole 102, and the petiole 102 is provided with a conical structure 3;

[0053] Further, the petiole 102 also includes a cylindrical connecting piece 4. When there are two truncated conical structures 3, they are respectively the first truncated circular structure 301 and the second truncated circular structure 302. At this time, the first truncated circular structure 301 and the second truncated circular structure 302 are respectively provided at both ends of the cylindrical connector 4 .

[0054] During installation, two truncated circular structures 3 and cylindrical connector...

Embodiment 2

[0060] As a further improvement of the above embodiment, this embodiment also includes a shaft sleeve 4 used in conjunction with the hub 2, the end of the hub 2 is provided with a connection port 6, and the shaft sleeve 5 is snapped into the hub 2 Connection port 6.

[0061] Refer to attached Figure 5 and 6 As shown, the boss 7 is provided on the shaft sleeve 5 , a through hole 8 is provided on the hub 2 , and a positioning hole 9 is provided on the boss 7 corresponding to the through hole 8 . The through hole 8 and the positioning hole 9 are provided, so that the shaft sleeve 5 and the hub 2 can be locked and installed conveniently through the locking bolt 12 .

[0062] Further, the bushing 5 is an essential part for connecting the impeller and the motor. Firstly, through the bushing 5, the impeller formed by the blade 1 and the hub 2 and the bushing are connected together; secondly, through the through hole 8 and the positioning hole 9 Connect and lock the shaft sleeve 5...

Embodiment 3

[0066] In this embodiment, the hub 2 includes a first hub 201 and a second hub 202 with symmetrical structures. By splitting the hub 2 into a first hub 201 and a second hub 202 with symmetrical structures, the installation of the entire impeller is made simpler. Compared with the prior art, when the hub 2 is integrated, the need for U-shaped clips for installation together is reduced. Or built-in tapered card; reduce the production process, improve production efficiency, increase output, and provide processing accuracy.

[0067] When the hub 2 includes a first hub 201 and a second hub 202 , both the first hub 201 and the second hub 202 are provided with through holes 8 .

[0068] Further, refer to the attached Figure 6 It can be seen that the structures of the first hub 201 and the second hub 202 are symmetrical, and the first hub 201 and the second hub 202 are respectively provided with a plurality of first installation grooves 13 and second installation grooves 14 for inst...

Abstract

The invention discloses a novel vane wheel and an installing method thereof. The vane wheel comprises a hub and multiple blades, and the multiple blades are evenly installed on the hub; each blade comprises a blade surface and a blade handle, and each blade handle is provided with a circular truncated cone structure; and the hub is provided with installing slots matched with the blade handles, and the blades are installed on the hub through the installing slots. The novel vane wheel has the advantages that installation is convenient to achieve, angle adjustment is convenient to achieve, and the service life of the vane wheel is long.

Description

technical field [0001] The invention belongs to the technical field of impellers for axial fans, and in particular relates to a novel impeller and an installation method thereof. Background technique [0002] Generally, the impeller includes blades and hubs. Currently, the commonly used installation method is that the blades are fixed and the installation angle cannot be adjusted. Specifically, it includes the following three types: [0003] 1) Weld the blades directly on the hub; [0004] 2), the blade and the hub are cast into one; [0005] 3) The petiole is trapezoidal, and the petiole and the impeller flange are connected together by bolts. [0006] The production of the above three methods is relatively complicated, the production process is relatively complicated and the installation angle of the blades cannot be adjusted, and the production cost is relatively high. [0007] In the prior art, the adjustment of the installation angle of the blade mainly includes the ...
