以有限元弹性接触分析理论为基础,建立了大型风力发电机组升速齿轮箱传动系统外啮合和内啮合齿轮多齿接触三维有限元模型,提出了一种内、外齿轮副啮合过程中的实际接触齿对数、齿间载荷分配及齿面载荷分布的计算方法。以某大型风力发电升速齿轮箱传动系统为例,对其在额定载荷工况下的承载能力进行了计算,为大型风力发电升速齿轮箱传动系统承载能力的估算、齿轮几何参数的确定及零部件的强度分析计算提供了理论依据。

Study on Multi-teeth Contact and Load Distribution of Speed Increase Gearbox Transmission System for the Wind-driven Generator

Based on the finite element contact theory multi-tooth contact finite element models are established for both external and internal gearing. An approach is presented to calculate the number of gearing teeth, load distribution in gearing teeth and the tooth surfaces. The proposed approach was applied to analyze the gearbox transmission system of a large-scale wind-driven generator. A theoretical foundation was built for estimating workload capacity, determining geometry parameters of gears, and analyzing the strength of parts of the gear transmission system.
