摘　　要：风力发电机齿轮箱是风力发电机组的关键部件之一,必须保证其在正常工作状态下运转平稳且无冲击振动或异常噪音,则应采取必要的减振降噪措施,使噪声声压级符合要求,最常用的解决方法就是安装减振支撑。鉴于此,介绍了目前大功率风力发电机组中主要采用的几种齿轮箱减振支撑方法,并分析了各种减振支撑的结构形式、性能特点、载荷的计算和适用的载荷工况,为风力发电机的传动系统选择适当的齿轮箱减振系统提供了可靠的依据。Gearbox is one of the most important components assembly in Wind Turbine, which must run stationary with no impact and abnormal noise in normal operation. The level of noise must meet the requirement by taking the anti-virbration action. The most common method of anti-virbration is the installation of virbration damper. In view of this, several gearbox suspensions mainly used at present are briefly introduced in High-power Wind Turbine. The Structures, performance features, load calculations and applicable conditions of gearbox suspensions are analysed, which provides a reliable basis for the selection of gearbox anti-vibration system in drive system.
