Wind power big ball milling process

Abstract

The invention relates to a wind power big ball milling process. The process comprises the following steps that firstly, a wind power big ball is added into a special hard milling device, and ball milling processing is waited; a ball milling motor drives a static ball milling plate to rotate, and ball milling processing is started; after ball milling processing is started, a ball screw drives a movable ball milling plate to move towards the static ball milling plate so as to apply pressure to a wind power steel ball; and the hard milling process is divided into four stages, the hard milling time is 2 hours, and hard milling is completed after 2 hours; and after hard milling is finished, the wind power big ball is sent out from an air outlet of the static ball milling plate, and hard milling processing of the wind power big ball is completed. Compared with the prior art, the method has the advantages that the special hard milling device is combined with four different stages of ball milling processes, on the basis that each time the pressure stability can be guaranteed, the wind power big balls are subjected to ball milling treatment through different pressurization forces in the four stages, the ball milling effect on the wind power big balls is better, and the ball milling quality of the wind power big balls is guaranteed.

Description

technical field [0001] The invention relates to the field of wind power large ball processing, in particular to a wind power large ball grinding process. Background technique [0002] Due to its environmental protection, wind power generation has been highly valued by various countries in the world in recent years, and the situation of wind power industry has developed quite rapidly. my country's wind power market needs about 30 million special steel balls for wind power bearings, and the international market needs about 1.5 billion. Therefore, special steel balls for wind power generation have broad market prospects. [0003] Steel ball bearings on wind turbines generally include: yaw bearings, pitch bearings, and generator bearings. For example, the horizontal axis wind turbine must yaw to achieve facing the wind. The yaw bearing is an important part of the yaw system. It is located at the bottom of the nacelle, carrying all the mass of the main drive system of the wind ...

Problems solved by technology

In the above-mentioned process, the pressurizing device is composed of hydraulic motors, solenoid valves, pistons, oil seal pipelines and other components. When using such a pressurizing device, oil will be used as the medium during the entire operation process. Therefore, it is inevitable to encounter some problems: for example, the pressure device will be affected by factors such as the temperature of the external environment after a summer and winter work, resulting in a large change in oil temperature, which is easy to cause oil seal aging , easy to leak oil, affecting normal work, large amount of equipment maintenance, time-consuming, and consumables; in addition, when oil leakage occurs, the pressure of the pressurizing device will be unstable, making it difficult for employees to grasp the quality of the product during pressurized production. quality, resulting in unstable product quality, and the volatilization of oil will pollute the surrounding environment, increase the workload of employees, and the production cost remains high, and this kind of oil leakage cannot be avoided, and when there is oil on the ground, the employees When passing through oily ground, it is easy to fall and other phenomena, which poses a safety hazard; in addition, in the process of pressurizing with such a pressurizing device, the hydraulic motor needs to keep working for a long time to maintain this pressurizing pressure. This kind of consumption is also a long-term consumption, and the labor intensity of the workers is relatively high, often causing chain failures and other adverse consequences due to unstable pressure, clapping, etc.
