In the discourse,the characters of wind generator are introduced briefly,while parameters and types of wind generators are also narrated. Base on these,the theory and constitution of the wind generator are meticulously analyzed. Firstly,Has carried on the design to wind-driven generator's overall mechanism, And has designed the regulating control system. What I design is one kind of new vertical axis small wind-driven generator, by the air blower impeller, the column, the crossbeam, the gearshift mechanism, the engaging and disengaging gear and the generator is composed. This kind of generator has the volume to be small, the noise is small, the service life is long, the price low characteristic, suits in has the wind energy resources area building crown, the supply family uses electricity, For example illumination: The light bulb, conserves energy the lamp; Domestic electric appliances: Television, radio, electric fan, washer, electric refrigerator.Secondly,I have manufactured the regulating control model. Through model verification small perpendicular wind-driven generator regulating control system overall concept effect in reality, and has confirmed the procedure to be whether correct, as well as electric circuit's design to be whether reasonable.Finally,Model verification's result indicated I design the regulating control system plan is feasible, the procedure is correct, the circuit design is reasonable. It provides according as theory for qualitative design and commercial manufacture of this type of wind generator.Key words:Wind power generation;Regulating control system;Small wind-driven generator;Small vertical axis wind-driven generator.目录前言1第一章 概述21.1 风力发电机概况21.2 风力发电机的研究现状31.2.1 国外风力发电机的研制情况31.2.2 国内风力发电机的研制情况6 我国风力发电概况61.3 研究风力发电机的目的和意义101.4 我国的风能资源及其分布12第二章 风力机理论162.1 基本公式162.1.1 风能利用系数162.1.2 风压强162.1.3 阻力式风力机的最大效率162.2 工作风速与输出功率182.2.1 风力发电机的输出效率182.2.2 工作风速与输出功率182.2.3 启动风速和额定风速的选定19 起动风速20 额定风速21 风力机的工作风速、输出功率与风能的关系222.3 风能利用与气象232.3.1 风的观测对风能利用的意义232.3.2 风能利用中需要的气象调查232.4 风的观测23第三章 风力发电机方案和结构设计253.1 小型垂直式风力发电机方案设计253.2 风轮的结构设计273.2.1风轮设计273.2.2 风轮桨叶的结构设计29第四章 行星齿轮加速器设计计算314.1 设计要求314.2 选加速器类型314.3 确定行星轮数和齿数324.4 压力角( )的选择324.5 齿宽系数的选择334.6 模数选择334.7 预设啮合角334.8 太阳轮与行星轮之间的传动计算334.9 行星轮与内齿轮之间的传动计算344.10 行星排各零件转速及扭矩的计算354.11 行星排上各零件受力分析及计算364.12 行星齿轮传动的强度校核计算374.12.1弯曲疲劳强度校核374.12.2接触疲劳强度校核40第五章 电磁离合器设计计算435.1 选型435.2 牙嵌式电磁离合器的动作特性435.3 离合器的计算转矩435.4 离合器的外径445.5 离合器牙间的压紧力445.6 线圈槽高度445.7 磁轭底部厚度445.8 衔铁厚度45第六章 结束语46致谢47参考文献48
