Finite Element Analysis of TaizhongⅢ Wind Turbille Gearbox

风电增速齿轮箱在兆瓦级风力发电机中属易过载和损坏率较高的部件,对其性能进行分析,预测其性能并进行优化是十分必要的。本文中利用ANSYS软件对太重Ⅲ型两级行星一级平行轴1.5MW风力发电增速齿轮箱进行有限元分析,对太重Ⅲ型风力发电增速齿轮箱各级齿轮强度进行校核,得到了各级齿轮副的齿廓和齿向修形数据;对行星轮系载荷均载特性、主箱体组件、行星架、花键联接等进行分析,得到了风力发电增速齿轮箱各级零部件强度和刚度等相关数据,为风电增速齿轮箱的可靠性评估及优化设计奠定基础。

Wind turbine gearbox is a key part in MW wind power generator,which is more easily over load and has a high failure rate. It is necessary to analyzed,predict and opimize its performance. The finite element analysis(FEA) results of Taizhong Ⅲ 1.5MW wind turbine gearbox with two stages planet and one class parallel shaft are presented by using the software ANSYS. The strength of each stage gear of the gearbox are checked. The data of tooth profile and helical modification are obtained by the analysis. And the housing component and planet carrier as well as the splines are analyzed. The related data on the strength and stiffness of all the parts in wind turbine gearbox are provided. It lays a foundation for the reliability assessment and opitimization design of wind turbine gearbox.
