摘要

基于风电轴承全工况需求,该文构建非线性弹簧-全局有限元耦合模型,揭示风电轴承动态载荷分布规律,通过滚道-油沟子模型精准表征淬硬深度对油沟应力场的影响,并提出风电场景下油沟淬硬层深度临界阈值的判定方法。研究表明,风电变桨系统轴承油沟等效应力随淬硬层深度增加呈指数衰减规律,疲劳损伤随淬硬层深度增加呈陡降-平稳两阶段变化趋势。基于风电设备高可靠性与工艺经济性的需求,确定该风电轴承油沟最小淬硬层深度应当不小于3.08 mm。

Abstract

To meet the comprehensive operating requirements of wind turbine bearings, this study develops a nonlinear spring-global finite element coupling model to analyze the dynamic load distribution. A raceway-oil groove sub-model is employed to accurately characterize the effect of case hardening depth on the stress field of oil grooves. Furthermore, a method for determining the critical threshold of case hardening depth for oil grooves is proposed. The results indicate that the equivalent stress of the oil groove in wind turbine pitch bearings decreases exponentially with increasing case hardening depth, while the fatigue damage exhibits a two-stage pattern of steep decline followed by gradual stabilization. Considering the high reliability and manufacturing economy of wind power equipment, the minimum case hardening depth for the oil groove is determined to be no less than 3.08 mm.
