摘要
以有限元分析方法为基础,介绍了风力发电机变桨轴承在空载和钢球预过盈的情况下摩擦力矩的计算方法,进而研究了安装单排钢球和双排钢球空载变桨轴承摩擦力矩比值的理想值,结果表明,变桨轴承空载时理想的摩擦力矩比小于2,大致为1.3~1.4。
Based on finite element analysis,the calculation of friction torque is introduced for wind turbine blade bearings with balls preloaded under no-load,and the ideal value for friction torque ratio of bearings filled with single row and two rows of balls is studied.The results show that the ideal friction torque ratio of blade bearings without load is smaller than 2,approximate 1.3~1.4.
