以某大兆瓦风电齿轮箱的变截面柔性销为研究对象,建立了考虑剪切变形影响的挠曲线微分方程,并使用格林函数法求解得到了变截面柔性销的挠度方程和转角方程;通过与工程算法和有限元方法的计算结果进行比较分析,验证了求解方法的有效性。利用Romax软件建立了风电齿轮箱仿真模型,验证了变截面柔性销的变形特性对啮合齿轮的齿面载荷分布以及均载系数的改善作用,并探究了销轴支承刚度、齿轮啮合错位对均载性能的影响规律。研究结果为风电行星齿轮箱均载性能提升及变截面柔性销设计优化提供了理论依据。
In this study
a variable cross-sectional flexible pin of a megawatt wind turbine gearbox is taken as the research object
and the deflection curve equation of the variable cross-sectional flexible pin considering the influence of shear deformation is established. The deflection equation and slope-deflection equation of the variable cross-sectional flexible pin are obtained by using the Green's function method. The effectiveness of this method is verified by comparing with the calculation results of the engineering algorithm and the finite element method. The simulation model of the wind power gearbox is established using Romax software
and it is verified that the deformation characteristics of the variable cross-sectional flexible pin can improve the load distribution and load sharing coefficient. The influence of the supporting stiffness of the pin and gear mesh misalignment on the load sharing performance is investigated. The research results provide a theoretical basis for improving the load sharing performance of the wind turbine gearbox and the design optimization of the variable cross-sectional flexible pin.
