1、Meng GaoqiangPart1不同传动链路线特点Characteristics of Different Drive Train Routes优点：齿轮箱和发电机均独立制造、测试、安装，制造安装方便并且易于扩展更换。Advantage:Both the gearbox and the generator can be independently manufactured,tested,and installed,featuring convenient manufacturing and installation as well as easy expansion and replace

2、ment.缺点：齿轮箱与主轴需增加传动法兰；高速轴对中受后机座刚度影响；齿轮箱高速级可靠性相对低一些。Disadvantages:1.An additional drive flange is required between the gearbox and the main shaft;2.The alignment of the high-speed shaft is affected by the stiffness of the rear engine base;3.The reliability of the gearboxs high-speed stage is relative

3、ly lower.三点支撑双馈Three-Point Supported Doubly-Fed Induction Generator(DFIG)四点支撑双馈Four-point support doubly-fed优点：齿轮箱和发电机均独立制造、测试、安装，易于扩展更换；适合采用高速双馈齿轮箱。Advantages:Both the gearbox and the generator can be independently manufactured,tested,and installed,facilitating easy expansion and replacement.It is

4、suitable for adopting high-speed doubly-fed gearboxes.缺点：齿轮箱低速级损坏需整体下架；高速轴对中受后机座刚度影响；齿轮箱受弯矩。Disadvantages:If the low-speed stage of the gearbox is damaged,the entire unit needs to be lifted off the tower for maintenance.The alignment of the high-speed shaft is affected by the stiffness of the rear e

5、ngine base.The gearbox is subjected to bending moments.1、不 同 传 动 链 对 比 Comparison of Different Drive Trains主轴承形式：单个调心滚子轴承Main Bearing Type:Single self-aligning roller bearing主轴承形式：1、两个单列调心滚子轴承2、两个单列圆锥滚子轴承Main Bearing Type:Two single-row self-aligning roller bearingsTwo single-row tapered roller bear
