摘要

时变风载是风电增速齿轮系破坏的重要原因之一,因此对处于极端恶劣工况风电增速齿轮系动态啮合研究非常重要。以风电斜齿行星轮系为对象,考虑齿侧间隙、轴承游隙及摩擦对啮合的影响,建立了风电斜齿行星齿轮系有限元模型。采用非线性动力学方法,研究了行星齿轮与太阳轮、内齿轮啮合过程中其齿根弯曲应力的变化规律,分析了转速对其啮合冲击应力的影响。通过分析计算得出:转速增加能使齿根弯曲应力曲线提前,行星轮的冲击应力不一定会随着转速的提升而变大;齿轮箱和传动轴受到的冲击应力会随着转速的提升而变大,同时冲力应力曲线整体前移。

Abstract

The dynamic meshing study is essential for the wind turbine which works in a harsh condition,especially,the gear train will be destructed by the time-varying load.Taking a wind turbine helical planetary gear train as study object,considering the influence of a variety of clearance and friction on meshing,a FEM model is built.By using the nonlinear dynamics method,the variation law of the gear tooth root bending stresses in the processing of the planet gear meshing with the sun gear or the internal gear is studied,the influence of the rotating speed on the meshing impact stresses is analyzed.Though the analyzing,with the speed increasing,the meshing stresses curve could get ahead,the impact stress of gear box and drive shaft will increase,while the curve of the impact stress are overall forward.However,the impact stress can’t always increase with the impact speed increasing.
