摘要

为提高风力发电机组的可靠性和使用寿命，本文以风力发电机组两级定轴齿轮箱实验平台为研究对象。以赫兹接触理论为基础，结合弹流体动力学润滑方程和牛顿拉夫逊法，求解了接触区域的油膜压力和厚度，并对传动系统的润滑特性进行了分析，验证了该方法的正确性；同时，针对系统耦合变形引起的偏载现象，选用遗传算法对轮齿进行了修正。结果表明，改造后齿面的最大单位载荷和齿根的最大应力分别降低了 26.48% 和 20.35%，从而改善了油膜的不均匀分布和齿面的润滑性能。

Optimization of lubrication characteristics of wind turbine’s transmission system based on Newton Raphson method

To improve the reliability and lifespan of wind turbines, this paper takes the two-stage fixed shaft gearbox experimental platform of wind turbines as the research object. Based on Hertz contact theory, the oil film pressure and thickness in the contact area are solved by combining the equations of elastohydrodynamic lubrication and the Newton Raphson method; And the lubrication characteristics of the transmission system were analyzed to verify the correctness of the method; At the same time, in response to partial load phenomenon caused by system coupling deformation, genetic algorithm was selected to modify the gear teeth. The results show that the max unit load on the tooth face and the maximum stress of tooth root decreased by up to 26.48 % and up to 20.35 % respectively after modification which can improve the uneven distribution of oil film and the lubrication performance of the tooth surface.
