摘要
某MW级的风电机组偏航齿轮箱在并网运行3年时间后,出现输出小齿轮轮齿折断问题。针对失效齿轮开展了全面分析,对轮齿断口、设计因素、制造因素、装配及运行因素、系统保护因素等可能导致齿轮失效的原因进行了逐一排查,最终定位为推力瓦支座与偏航齿圈之间干涉是直接原因。经过bladed软件模拟叶轮不平衡并进行风场验证,得知风轮的一只叶片安装角度出现偏差,造成风轮气动不平衡是失效的根本原因。
The output pinion of a MW-class wind turbine yaw gearbox has been broken down after about3 years in the grid. The comprehensive analysis is carried out on the failure gears,the causes of gear damage,such as tooth fracture,design factor,production factor,factors of assembly and operation,system protection factor,etc. are analyzed one by one,the final positioning between the thrust pad bearing and yaw ring interference is the direct cause. Bladed software is used to simulate the impeller imbalance and verify the wind field.It is concluded that the deviation of the installation angle of a blade of the wind turbine causes the aerodynamic imbalance of the wind wheel is the root cause of the failure.
