摘要
以某型号柔性销轴结构的风电齿轮箱行星传动系统为研究对象,分析了柔性销轴的基本结构和均载原理;利用有限元方法对风电齿轮箱进行静强度计算、变形分析和齿轮接触应力分析;结果表明:柔性销结构的等效应力、齿轮齿根的弯曲应力、齿面上的接触应力均满足要求;套筒母线上的位移曲线近似一条直线,说明销套在受载情况下保持平行移动;齿轮接触应力在沿齿宽方向分布基本一致。柔性销结构能实现风电齿轮箱齿轮间均载性。
In order to study the planetary transmission system of a certain type of flexible pin shaft structure, the basic structure and load sharing principle of the flexible pin shaft are analyzed briefly. The static strength calculation, deformation analysis and gear contact stress analysis are carried out by using the finite element method. The results show that the equivalent stress of the flexible pin structure, the bending stress of the gear root and the contact stress on the tooth surface meet the requirements of performance. The displacement curve on the sleeve bus is approximately a straight line, which means that the pin sleeve keeps parallel movement under loaded conditions. The contact stress distribution of the gear is basically the same along the tooth width direction. The flexible pin structure can realize load sharing between the gears of the wind power gearbox.
