摘要:齿轮箱的可靠性和寿命对风力发电机组的平稳运行起着至关重要的作用,齿轮修形能有效地减小齿轮箱振动、降低噪音以及延长使用寿命。本文以5 MW功率分流风电齿轮箱为研究对象,简要介绍了齿轮修形理论以及功率分流式风电齿轮箱的基本结构;利用Romax软件建立了5 MW功率分流齿轮箱模型,利用载荷谱对齿轮箱进行静力学仿真分析,根据齿轮载荷分布、传动误差等参数,对一、二级的齿轮进行齿廓和齿向修形,实现功率分流式风电齿轮箱齿轮间的均载特性,减小齿轮传动误差。

Abstract:Gear modification can effectively reduce gearbox vibration and noise and extend the service life. This paper studies a 5 MW power-split wind power gearbox. Based on the theory of gear modification and the analysis of basic structure of the power shunt wind power gearbox, we establish a 5 MW power-split gearbox model with software Romax. A static simulation analysis of the gearbox is conducted by using the load spectrum, and tooth profile and tooth direction of the first and second stage gears is modified according to the gear load distribution, transmission error and other parameters. With tooth modification, the load sharing characteristic between the gears of the power split type wind power gearbox is realized, and the transmission error of the gears is reduced. 
Key words:power-split;wind power gearbox;gear modification;Romax;load characteristics
