摘　　要：速比可变式风电齿轮箱可将变化的转速输入调整为恒定的转速输出,是前端调速型风力发电机组的核心部件。基于NGW型差动轮系传动原理,分析了几种速比可变式风电齿轮箱的传动机构,推导出每种机构对应的参数计算表达式和齿轮设计边界条件,应用专业设计软件RomaxWIND对推导的公式进行了验证,并列举了实际案例,对该类齿轮箱的设计具有一定的参考和帮助。The variable-ratio wind turbine gearbox turns the variable input speed into constant output speed,which is a key component for the wind turbine front-end speed control. On the basis of the transmission principle of NGW differential gear train system,several types of variable-ratio transmission mechanisms of wind turbine gearbox are studied. The corresponding expressions and boundary conditions for gear design are derived for each mechanism, and the derived expressions are verified through professional software Romax WIND. At last,the actual example is enumerated,which is helpful for the design of this type of gearbox.
