[0002] The hubs used in existing fans and cooling towers have insufficient torsional resistance and are prone to deformation after long-term use, which in turn leads to uneven wind pressure and vibration problems. Utility Model Content

[0003] The purpose of the present utility model is to provide an integrally forged fan hub disc to solve at least one of the above-mentioned problems existing in the prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The integrally forged fan hub comprises a wheel disc and a wheel core, wherein the wheel core is fixedly arranged in the middle of the wheel disc, and a plurality of arc-shaped grooves are evenly arranged on one side of the wheel disc in the circumferential direction, and the arc-shaped grooves extend toward the wheel core;

[0006] An arc-shaped plate is provided on one side of the arc-shaped groove, and an installation space is formed between the arc-shaped plate and the arc-shaped groove. The outer side of the arc-shaped plate is fixed to the wheel disc through a plurality of U-shaped bolts;

[0007] Alternatively, a second wheel disc is provided on one side of the wheel disc, and a second arc groove is formed on the side of the second wheel disc opposite to the arc groove, an installation space is formed between the arc groove and the second arc groove, and a plurality of connecting bolts are provided between the wheel disc and the second wheel disc on both sides of the arc groove and the second arc groove.

[0008] This technical solution provides an arc groove on the wheel disc, and an arc plate is provided on one side of the arc groove. The installation and fixing effect of the installation space can be adjusted by U-shaped bolts, and the installation stability and reliability are higher. Since a second wheel disc is provided on one side of the wheel disc, an installation space is formed between the arc groove and the second arc groove by the provision of the second arc groove on the second wheel disc. The wheel disc and the second wheel disc can be fixed by connecting bolts, and the installation stability and reliability are higher. It solves the problem that the wheel hub used in the existing fans and cooling towers has insufficient torsional resistance and is easy to deform after long-term use, which leads to uneven wind pressure and vibration.

[0009] Furthermore, in the prior art, most wheel hubs are cast, have poor toughness, and are easily deformed. The wheel disc, the curved plate, and the second wheel disc are all formed by a carbon steel plate forging process, have higher toughness, and are not easily deformed.

[0010] The beneficial effects of the present invention are as follows: according to the technical solution, an arc groove is provided on the wheel disc, and an arc plate is provided on one side of the arc groove. The installation and fixing effect of the installation space can be adjusted by the U-shaped bolt, and the installation stability and reliability are higher; since a second wheel disc is provided on one side of the wheel disc, an installation space is formed between the arc groove and the second arc groove by the setting of the second arc groove on the second wheel disc, and the wheel disc and the second wheel disc can be fixed by connecting bolts, and the installation stability and reliability are higher, which solves the problem that the wheel hub used in the existing fan and cooling tower has insufficient torsional resistance and is easy to deform after long-term use, thereby causing uneven wind pressure and vibration.

[0016] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly introduced below in conjunction with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structures of the drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0017] Example 1:

[0018] like Figure 1-Figure 4 As shown, this embodiment provides an integrally forged fan hub disc, comprising a disc 1 and a wheel core 2. The wheel core 2 is fixedly disposed in the middle of the disc 1. A plurality of arcuate grooves 3 are uniformly provided on one side of the disc 1 along the circumference. Specifically, four arcuate grooves 3 are provided. The arcuate grooves 3 extend toward the wheel core 2.

[0019] An arc-shaped plate 4 is provided on one side of the arc-shaped groove 3, and an installation space 6 is formed between the arc-shaped plate 4 and the arc-shaped groove 3. The outer side of the arc-shaped plate 4 is fixedly mounted on the wheel disc 1 by a plurality of U-shaped bolts 7;

[0020] Alternatively, a second wheel disc 8 is provided on one side of the wheel disc 1, and a second arc groove 9 is formed on the side of the second wheel disc 8 opposite to the arc groove 3, and an installation space 6 is formed between the arc groove 3 and the second arc groove 9. A plurality of connecting bolts 10 are provided between the wheel disc 1 and the second wheel disc 8 on both sides of the arc groove 3 and the second arc groove 9.

[0021] This technical solution provides an arc groove 3 on the wheel disc 1, and an arc plate 4 is provided on one side of the arc groove 3. The installation and fixing effect of the installation space 6 can be adjusted by the U-shaped bolt 7, and the installation stability and reliability are higher. Since a second wheel disc 8 is provided on one side of the wheel disc 1, the second arc groove 9 on the second wheel disc 8 forms an installation space 6 between the arc groove 3 and the second arc groove 9. The wheel disc 1 and the second wheel disc 8 can be fixed by the connecting bolt 10, and the installation stability and reliability are higher. This solves the problem that the hub used in existing fans and cooling towers has insufficient torsional resistance and is easily deformed after long-term use, which leads to uneven wind pressure and vibration. While improving the quality and stability of the fan, it saves a lot of labor and time costs, thereby enabling mass production.

[0022] Example 2:

[0023] This embodiment is optimized based on the above embodiment 1.

[0024] In the prior art, most wheel hubs are cast, which have poor toughness and are easy to deform. In this technical solution, the wheel disc 1, the arc plate 4 and the second wheel disc 8 are all formed by a carbon steel plate forging process, which has higher toughness and is not easy to deform.

[0025] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
