风力发电机齿轮增速箱毕业设计HUA system office room 【HUA16H-TTMS2A-HUAS8Q8-HUAH1688】摘要风电产业的飞速发展促成了风电装备制造业的繁荣，风电齿轮箱作为风电机组的核心部件，倍受国内外风电相关行业和研究机构的关注。
但由于国内风电齿轮箱的研究起步较晚，技术薄弱，特别是兆瓦级风电齿轮箱，主要依靠引进国外技术。
因此，急需对兆瓦级风电齿轮箱进行自主开发研究，真正掌握风电齿轮箱设计制造技术，以实现风机国产化目标。
本文设计的是兆瓦级风力发电机组的齿轮箱，通过方案的选取，齿轮参数计算等对其配套的齿轮箱进行自主设计。
1）根据风电齿轮箱承受载荷的复杂性，对其载荷情况进行了分析研究,确定齿轮箱的机械结构。
选取两级行星派生型传动方案，在此基础上进行传动比分配与各级传动参数如模数，齿数，螺旋角等的确定；通过计算，确定各级传动的齿轮参数；选择适当的齿轮。
2）对行星齿轮传动进行受力分析，得出各级齿轮载荷结果。
依据标准进行静强度校核，结果符合安全要求。
3）绘制CAD装配图，并确定恰当合理参数。

ABSTRACTThe rapid development of wind power industry lead to the prosperity of wind power equipment manufacturing industry．As the core component of wind turbine，the gearbox is received much concern from related industries and research institution both at home and abroad．However, due to the domestic research of gearbox for wind turbine starts late，technology is weak，especially in the gearboxfor MW wind turbine，which mainly relied on the introduction of foreign technology．Therefore，it is urgent need to carry out independent development and research on MW wind power gearbox，and truly master the design and manufacturing technology in order to achieve the goal of localization．1）The load Cases of gearbox for wind turbines ale analyzed，and the interrelation of loading cycle numbers under different torque levels is deduced according to the curve of materials’fatigue．the mechanical structure of gearbox is determined．The two-stage derivation planetary transmission scheme is selected．The gear parameters of every stage transmission is calculated．，and the force analysis results is obtained．2）the static strength check of tooth surface contact is implemented according to related standard．The result shows that it is accord with safety requirements．3）Draw CAD drawings, and determine appropriate reasonable parameters.KEYWORDS：Gearbox for Wind Turbine；the wind power；Structure Design.目录第一章前言 ---------------------------------- 错误!未定义书签。
