摘　　要：风电主轴承是风力发电机组的核心部件,其性能直接影响风机可靠性和寿命。通过对4MW风电调心滚子主轴承进行材料、热处理质量、扫描电镜检测分析,结合Romax轴系仿真模型分析轴承两条滚道的受力状态,结果表明受轴向力、倾覆力矩联合作用,轴承出现偏载是导致一侧滚道疲劳的主要原因。对调心滚子风电主轴承进行优化设计并仿真分析,结果表明通过改变接触角进行非对称设计,可改善轴承受力状态。风电主轴承的失效分析与优化设计研究,可为大功率风电主轴承设计提供参考。Main bearing is the core component of wind turbine,its performance directly affects the reliability and life of wind tur-bine.Through the material,heat treatment quality and scanning electron microscopy detection and analysis of the 4MW wind turbine spherical roller bearing,combined with the Romax shafting simulation model,the stress state of the bearing’s two race-ways was analyzed.The results showed that,under the combined action of axial force and overturning moment,the deflection load of the bearing was the main cause of raceway fatigue.The optimization design and simulation analysis of the SRB show that the bearing stress state can be improved by changing the contact Angle to carry out asymmetric design.The failure analysis and optimization design of wind power main bearing can provide reference for the design of high power wind turbine main bearing.
