摘　　要：主齿轮箱作为风力发电机组的核心零部件,其稳定可靠性直接决定风力发电机组的正常运行,其在机组中成本占比高也作为机组降成本的首选目标,主齿箱的各级传动比分配既决定了各级齿轮承载能力,也对齿轮箱的整体重量起着决定作用,本文主要以齿面接触疲劳强度为准则,综合考虑不均载系数、行星轮个数等因素,以质量之和、外径之和为优化目标介绍三级典型的NGW传动结构的齿数比分配原则与优化方法,具有很强的工程实用与经济意义。As the core component of the wind turbine,the stability and reliability of the main gearbox directly determine the normal operation of the wind turbine.Its high proportion of cost in the unit is also the first choice for cost reduction of the unit.The main gearbox at all levels The transmission ratio distribution not only determines the load-carrying capacity of the gears at all levels,but also plays a decisive role in the overall weight of the gearbox.This paper mainly takes the contact fatigue strength of the tooth surface as the criterion,and comprehensively considers factors such as the uneven load coefficient and the number of planetary gears.The sum of mass and the sum of outer diameters are used to introduce the gear ratio distribution principle and optimization method of the three-stage typical NGW transmission structure,which has strong engineering practical and economic significance.
