Manufacturing process for lightweight and noise reduction wind power yaw brake

Abstract

The invention discloses a manufacturing process for a lightweight and noise reduction wind power yaw brake. The manufacturing process includes the following steps: S1. processing an external surface of a cylinder body insert member to make the insert member rough; S2. engraving a sandwich material into a predetermined shape by utilizing an engraving machine; S3. coating the surface of the insert member with epoxy glue, and wrapping in a unidirectional basalt fiber prepreg material; S4. paving the sandwich material on the surface of the cylinder body insert member wrapped in the basalt fiber prepreg material; S5. paving the unidirectional basalt fiber prepreg material on the surface of the sandwich material, and then paving the surface twill type basalt fiber prepreg cloth on the surface toform into a preformed body; and S6. placing the preformed body of the step S5 in a mold, and placing in a pressing machine for stitching for 2-5 hours at 120-200 DEG C after mold matching. The manufacturing process adopts a molding process, takes PVC, PET, PMI, PU, and the like as the sandwich material, and basalt fibers are a reinforcement body and are embedded in a cylinder body. The yaw brakewith light weight and a noise absorbing function is prepared by the molding process.

Description

technical field [0001] The invention relates to a lightweight wind yaw brake with noise reduction. Background technique [0002] With the progress and development of the economy and society, wind power generation has become the most mature technology, the most large-scale development conditions and the most promising power generation method in the utilization of renewable new energy due to its endless resources, low cost and easy utilization. Wind power has begun to change from "supplementary energy" to "strategic alternative energy". [0003] As the season or weather changes, the wind direction in the wind field is constantly changing. In order to effectively use wind energy, the blades of the fan need to be aligned with the wind direction at all times. For this reason, a yaw braking system is specially designed in the wind turbine. The main functions of the yaw braking system are two: one is to keep the wind turbine in the windward state with the change of the wind direct...

AI Technical Summary

Problems solved by technology

At present, the yaw brakes installed on wind turbines are all made of metal materials, weighing several hundred kilograms, using more than a dozen bolts, and the tightening torque of each bolt is as high as several thousand NM, and the space in the cabin of the wind turbine is very small, so it is very difficult to replace.
