摘　　要：风能作为清洁能源已成为促进可再生能源发展的重要应用,风力发电机可将风能转化为电能,在降低二氧化碳排放中起到关键作用,其中,配对安装的单列圆锥滚子轴承在风力发电机中被广泛使用。传统设计方法通常以额定动载荷为目标进行设计,未同时考虑轴承体积影响与复杂风载荷作用。针对上述问题,本文基于传动链力学模型,通过建立风机主轴传动链力学模型以及风机主轴承的变形协调关系,求解轴承的滚动体接触载荷分布,希望能够为现代工业风机主轴承的力学特性与优化设计提供参考。Wind resources are abundant across the world,thus wind energy,as a kind of clean energy,has been playing a significant role in promoting the development of renewable energies.Wind turbines are crucial in reducing CO 2 emissions by converting wind energy into electricity,where single row tapered roller bearings installed in pairs are widely used.Traditional designs usually aim for rated dynamic loads,not considering the impact of bearing volume or complex wind loads.Against this backdrop,based on the transmission chain mechanical model,this paper touches upon the contact load distribution of rolling bearings by establishing the mechanical model of the wind turbine’s main transmission chain and the deformation coordination of its main bearing.The research results can provide a reference to study the mechanical characteristics and optimized design of main bearings on modern industrial wind turbines.
