Research on multi-synchronous tightening technology and intelligent tightening machine for shrink disc bolts of MW wind turbine

锁紧盘作为一种过盈机械连接装置,是双馈型兆瓦级风电机组主传动链不可缺少的重要部件之一,它对于风电机组主传动链扭矩传递至关重要。而对于锁紧盘的螺栓拧紧,在风机生产制造过程中是非常重要的环节。文章经过对锁紧盘螺栓拧紧工艺现状的研究,开发出一套最新式的拧紧工艺和智能化拧紧机,通过拧紧机配套的液压泵站PLC的闭环精确控制,可以实现锁紧盘螺栓锁紧的自动化作业。通过实践证明,该方法能大幅提高锁紧盘的螺栓拧紧效率,提高了风电机组的生产效率、装配质量和安全性能。

As an interference fit mechanical coupling,the shrink disc is one of the indispensable parts of the main drive chain of the doubly-fed MW wind turbine,and it is very important for torque transmission of the main drive chain of the wind turbine.But the bolt tightening of shrink disc is very important link in the production manufacture process.After studying the present situation of bolt tightening technology of shrink disc,we have developed a set of up-to-date tightening technology and intelligent tightening machine.Through closed-loop precise control of PLC in hydraulic pump station,the tightening machine can realize the automatic operation of bolt locking of the shrink disc.The practice shows that this method can greatly improve the bolt tightening efficiency of the shrink disc and improve the production efficiency,assembly quality and safety performance of the wind turbine.
