风力发电机组齿轮箱失效形式和振动特征

Wind Turbine Gearbox Failure Mode and Vibration Feature

文章阐述了齿轮失效的类型和成因,当齿轮出现失效时,可以通过对齿轮振动信号的边频带分析得到不同的失效类型,文章归纳和总结了齿轮不同失效类型所对应齿轮振动信号频谱的特征。

This article depicts types and causation of gear failure. When the gear failure occurs, different types of gear failure can be obtained through analyzing side band of the gear vibration signal. This article summarizes the gear vibration signal spectrum corre- sponding to characteristics in different gear failures.
