摘　　要：对双馈式风力发电机齿轮箱研究的必要性进行简单说明;探讨了齿轮箱各轴等效到主轴(风轮轴)上的刚度换算和转动惯量计算方法;推导了整个传动系统的主谐振频率;对1.5MW齿轮箱进行了主谐振频率计算,并与叶片穿越频率及齿轮啮合频率进行比较分析,得出结论为系统的主谐振频率主要表现为与叶片穿越频率振动区重叠。By comparing doubly-fed wind generator with direct drive wind turbine,a further study of the gear box for doubly-fed wind power generator is necessary.This paper discusses the stiffness conversion and inertial moment calculation on the shafts of the gear box,including gear shaft and motor shaft,deduces the main resonance frequency of the whole drive system,calculates the main resonance frequency of 1.5 MW gear box,and compares the through frequency of the blade with the gear meshing frequency.It draws the conclusion that the primary resonance frequency field of this system overlaps the through frequency field of the blade.
