Embodiment Construction

[0029] like Figure 1 to Figure 10 A disc spring loaded hydraulic disc brake shown is an improvement to the existing hydraulic disc brake. The purpose is to apply the finite element structure topology optimization technology, with the minimum volume and maximum structural stiffness as the optimization goal, configure the material density according to the optimal load transfer path, determine the conceptual design frame model, and obtain the optimal structural design scheme. This solution improves the rigidity of the structure, effectively reduces the deformation of the brake body, makes the brake pads evenly loaded, prolongs the service life, and improves the agility, accuracy and reliability of braking. Figure 11 In order to analyze the force transfer model of the brake according to the force of the brake, figure 1 , figure 2 , image 3 Designed for an improved brake shape. from figure 1 , Figure 11 It can be seen from the figure that along the force transmission p...

Abstract

The invention discloses a disc spring loading type hydraulic disc brake which is the improvement on a hydraulic disc brake of the traditional wind-driven generator. The traditional wind-driven generator has the problems that a spindle brake of the traditional wind-driven generator mainly adopts a disc brake which generally adopts a U-shaped structure, a brake body is arranged as a cantilever and has relatively larger loaded deformation, brake pieces are in uneven contact and have quick local wear, therefore, a machine needs to be stopped frequently for checking and replacing the brake pieces,moreover, a space between a brake piece and a brake disc of the traditional brake is small, wearing pieces are easy to scrape, and the traditional brake is inconvenient to install and regulate. The problems seriously influence the work efficiency and the braking reliability of a fan. The spindle brake of the wind-driven generator applies a finite element structural topology optimizing technology to increase structural rigidity, rhombic brake pieces are adopted to increase contact area, a scraping pin is adopted to increase the convenience for replacing the braking pieces, the installing spaceof the braking pieces and the brake disc is properly increased, and the work efficiency and the reliability of the brake are effectively improved.

Description

technical field [0001] The invention relates to an automatic brake, which is used for normal braking and emergency braking of a fan, or preventing the fan from rotating under maintenance and other working conditions; it can also be used for braking in other fields. Background technique [0002] As a clean energy, wind power has developed rapidly in recent years. At present, the wind turbine main shaft brake mainly adopts a disc brake. For the convenience of installation, this kind of brake generally adopts a "U" shape structure. The brake body is similar to the cantilever installation, and the load deformation is relatively large, resulting in uneven contact of the brake pads. , local wear is fast, so it is necessary to stop the machine frequently to check and replace the brake pads, which seriously affects the working efficiency of the fan and the reliability of the brake. In addition, the shape of the existing brake pads is similar to a rectangle, which easily causes the ...
