摘　　要：为了准确评估风电变桨轴承的安全性能,运用有限元软件ANSYS分析变桨轴承的沟曲率对轴承接触角、接触椭圆及接触应力的影响。根据计算,得出轴承滚动体与滚道之间的接触角和接触椭圆随沟曲率的增大而减小,接触应力随沟曲率的增大而增大。In order to accurately evaluate the safety performance of wind power pitch bearings,the finite element software ANSYS was used to analyze the influence of the groove curvature of the pitch bearings on the bearing contact angle,contact ellipse and contact stress.According to calculations,it is found that the contact angle and contact ellipse between the bearing rolling elements and the raceway decreases with the increase of groove curvature,and the contact stress increases with the increase of groove curvature.
