摘要
偏航系统是风力发电机组的重要组成部件,它承担着风力发电机组对风自动解缆的任务,偏航减速机是风力发电机组偏航系统的执行元件之一,承担着偏航扭矩的传递,使偏航电机的高转速、小扭矩转化为低转速、大扭矩,从而驱动机舱旋转,使风轮正对风向;因VESTAS的旧式减速机损坏频繁,现已大部分更换为新型减速机,新型减速机带有力矩限制功能,扭矩过大时内部脱扣限制过力矩的产生,以保护偏航系统,有效避免了偏航减速机断齿、内部齿轮损坏的发生,但是由于其采用磨片结构,随着时间的推移,内部磨片也会相应的磨损,造成输出力矩降低,无法驱动偏航系统正常工作,这会导致偏航系统频繁告警,造成风电机组可利用率降低,启停机频繁,按照VESTAS指导手册要求需要每半年对其力矩进行调整,来使其输出力矩达到要求,调节过程中需要使用专用工装,但由于该力矩调节工装存在诸多缺点,故对原有工装进行重新设计、升级。主要阐述了针对新型减速机力矩调节工装的设计和投入应用以来的实际情况。
The yaw system is an important component of wind turbine,which undertakes the task of wind turbine to wind and automatically unwind the cable.Yaw reducer is one of the executive components of the yaw system of wind turbine.It is responsible for the transmission of yaw torque,which transforms the high speed and small torque of yaw motor into low speed and large torque,so as to drive the engine room to rotate and make the wind wheel face to face Wind direction:as the old reducer of Vestas is frequently damaged,most of them have been replaced by new ones.The new reducer has the function of torque limitation.When the torque is too large,the internal tripping will limit the over torque,so as to protect the yaw system and effectively avoid the occurrence of broken teeth and internal gear damage of the yaw reducer.However,due to the use of the grinding plate structure,with the passage of time,the new type of reducer has the function of torque limitation,The internal grinding disc will also wear accordingly,resulting in the reduction of output torque and failure to drive the yaw system to work normally.This will cause frequent alarms of the yaw system,resulting in reduced availability of wind turbines and frequent start-up and shutdown.According to the requirements of Vestas guidance manual,the torque should be adjusted every half a year to make its output torque meet the requirements.Special tooling should be used in the adjustment process However,due to the shortcomings of the torque adjusting tooling,the original tooling was redesigned and upgraded.This paper briefl y describes the design and application of the new reducer torque adjusting tooling.
