摘　　要：在分析柔性销轴结构和工作原理的基础上,建立多浮动构件的柔性销轴式风电齿轮箱行星传动动力学模型,综合考虑行星传动时变啮合刚度、时变传递误差,研究柔性销轴刚度和误差对行星传动均载的影响。结果表明,柔性销轴支撑的行星轮具有较好的均载效果,减小销轴刚度能明显降低行星轮偏载载荷,提高均载性能;销轴切向误差对行星轮均载影响敏感,销轴公差设计应以相邻且同向配置为优。在专用齿轮传动试验台上对柔性销轴式风电齿轮箱行星传动进行均载试验研究,验证理论分析结果的有效性。Based on the analysis of the structure and working principle of the flexible pins,the dynamic model of planetary gear transmission of wind turbine gearbox is built.Time-varying mesh stiffness and mesh phasing with pins error are considered together to analyze the effects of pin stiffness and pins error on the load sharing.The results show that the load sharing is perfect in the flexible pins system,reduce pin stiffness can obviously reduce the maximum load percentage of planet gear and improve the load sharing.It is also showed that pin tangential error is sensitive to load sharing,and pin tolerance of adjacent pairs of planets in the same direction is best for the load sharing from the design viewpoint.The load sharing experimental studies of planetary gear transmission of wind turbine gearbox are performed on the professional test setup.The experimental results compare well with the theoretical results,verifying the theoretical method.
