[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4As shown, an anti-deformation blade flange of this utility model includes a flange body 1, which is an annular structure. A set of reinforcing ribs 2 are provided on the flange body 1. A set of evenly distributed rectangular grooves 3 are provided on the flange body 1. A set of anti-deformation ribs 4 are provided on both the inner and outer sides of the flange body 1, and the set of anti-deformation ribs 4 is integrally formed with the flange body 1.

[0025] During operation, by setting reinforcing ribs 2 and anti-deformation ribs 4 on the flange body 1, as well as opening rectangular grooves 3, the strength and rigidity of the flange can be effectively enhanced. At the same time, the stress during operation is dispersed and absorbed, preventing the flange from deforming under complex working conditions, improving the service life and reliability of the flange, and ensuring the stable connection between the blade and the main shaft.

[0026] The flange body 1 is made of high-strength alloy steel.

[0027] During operation, high-strength alloy steel has excellent mechanical properties, enabling it to withstand large loads and stresses, further improving the strength and rigidity of the flange. This allows it to maintain good performance under harsh conditions such as high temperature and high pressure, extending the service life of the flange and reducing maintenance costs.

[0028] The reinforcing rib 2 has a concave structure, and its two ends are connected to the inner and outer sides of the flange body 1, respectively.

[0029] During operation, the concave reinforcing ribs 2 can better integrate with the flange body 1 to form a stable reinforcing rib network, enhancing the overall stability of the flange and improving its resistance to deformation. At the same time, the concave structure design can also reduce the weight of the flange to a certain extent and improve the utilization rate of materials.

[0030] The depth of the rectangular groove 3 is 1 / 4 to 1 / 3 of the thickness of the flange body 1, and the width is 1 / 5 to 1 / 4 of the thickness of the flange body 1.

[0031] During operation, the dimensions of the rectangular groove 3 should be designed reasonably so that it can effectively disperse and absorb stress during operation without affecting the overall strength of the flange, avoid local deformation caused by stress concentration, and at the same time reduce the weight of the flange and improve its operating efficiency.

[0032] The thickness of the anti-deformation rib 4 is 1 / 6 to 1 / 5 of the thickness of the flange body 1.

[0033] During operation, the thickness of the anti-deformation rib 4 is designed within a reasonable range, which can not only ensure its support and reinforcement of the flange body 1, but also avoid material waste and weight increase caused by excessive thickness, so that the flange can have better economy and lightweight characteristics while ensuring performance.

[0034] A pair of reinforcing rings 5 ​​are provided on the top of the flange body 1, and the pair of reinforcing rings 5 ​​and a set of reinforcing ribs 2 are integrally formed.

[0035] During operation, the reinforcing ring 5 and the reinforcing rib 2 are integrated at the top, which further enhances the strength and rigidity of the top of the flange body 1, improves the flange's resistance to deformation under top stress, and ensures the stability and reliability of the overall structure of the flange during operation.

[0036] A set of mounting and positioning holes 6 are provided on the inner surface of the flange body 1, and the mounting and positioning holes 6 are evenly distributed around the perimeter of the flange body 1.

[0037] During operation, the mounting and positioning holes 6 on the inner surface can be precisely positioned and fixed with the connecting parts of the blade and the main shaft, ensuring the reliability and stability of the connection, reducing the risk of stress concentration and deformation caused by installation errors, and improving the installation accuracy and working efficiency of the flange.

[0038] The flange body 1 is coated with an anti-corrosion coating.

[0039] During operation, the anti-corrosion coating can effectively prevent the flange body 1 from being corroded in harsh environments, extend the service life of the flange, reduce maintenance costs, and at the same time improve the appearance quality and weather resistance of the flange, so that it can maintain good performance under various working conditions.

[0040] Working principle: By setting reinforcing ribs 2 and anti-deformation ribs 4 on the flange body 1, and opening rectangular grooves 3, the strength and rigidity of the flange can be effectively enhanced, while dispersing and absorbing stress during operation, preventing the flange from deforming under complex working conditions, improving the service life and reliability of the flange, and ensuring a stable connection between the blade and the main shaft.

[0041] High-strength alloy steel has excellent mechanical properties and can withstand large loads and stresses, further improving the strength and rigidity of flanges. This allows them to maintain good performance under harsh conditions such as high temperature and high pressure, extending the service life of flanges and reducing maintenance costs.

[0042] The concave reinforcing ribs 2 can better integrate with the flange body 1 to form a stable reinforcing rib network, enhance the overall stability of the flange, improve its resistance to deformation, and at the same time, the concave structure design can also reduce the weight of the flange to a certain extent and improve the utilization rate of materials.

[0043] The dimensions of the rectangular groove (3) are designed reasonably so that it can effectively disperse and absorb stress during operation without affecting the overall strength of the flange, avoid local deformation caused by stress concentration, and at the same time reduce the weight of the flange and improve its operating efficiency.

[0044] The thickness of the anti-deformation rib 4 is designed within a reasonable range, which can not only ensure its support and reinforcement of the flange body 1, but also avoid material waste and weight increase caused by excessive thickness, so that the flange can have better economy and lightweight characteristics while ensuring performance.

[0045] The reinforcing ring 5 and the reinforcing rib 2 are integrated at the top, which further enhances the strength and rigidity of the top of the flange body 1, improves the flange's resistance to deformation when subjected to top stress, and ensures the stability and reliability of the overall structure of the flange during operation.

[0046] The mounting and positioning holes 6 on the inner surface can accurately position and fix the connecting parts of the blade and the main shaft, ensuring the reliability and stability of the connection, reducing the risk of stress concentration and deformation caused by installation errors, and improving the installation accuracy and working efficiency of the flange.

[0047] The anti-corrosion coating can effectively prevent the flange body from being corroded in harsh environments, extend the service life of the flange, reduce maintenance costs, and improve the appearance quality and weather resistance of the flange, so that it can maintain good performance under various working conditions.
