国内外的应用实践表明,在风电齿轮箱的所有零部件里,轴承是最薄弱的环节之一。因此,对轴承进行必要的应用分析是保证齿轮箱可靠性的重要手段。风电齿轮箱是整个风机中非常重要的部件,由于常年受到变载荷及强阵风的冲击,因此在设计、制造和维护上都有别于普通齿轮箱。而且随着风机设计功率的不断提升,风电齿轮箱在满足传递载荷的前提下,体积必须要尽可能小,重量必须要尽可能轻,使用寿命却依然要达到20年以上。而国内外 Application practice at home and abroad shows that bearings are one of the weakest links in all the components of a wind turbine gearbox. Therefore, the necessary application analysis of the bearing is an important means to ensure the reliability of the gearbox. Wind turbine gearbox is a very important part of the entire fan, due to perennial subject to variable load and strong gusts of impact, so in the design, manufacture and maintenance are different from ordinary gearbox. And with the continuous improvement of fan design power, wind power gearbox to meet the delivery load under the premise, the volume must be as small as possible, the weight must be as light as possible, the service life is still to reach more than 20 years.
