摘 要
风力发电机顾名思义是依靠风所作用的能量进行发电的一种装置，最近几年，风机生产行业成长相当的迅速，作为风机整个机组中最为重要的部位，风机的齿轮箱的研究与发展一向被世界所关注。西方许多家已经掌握了许多核心技术，然而我国对风力发电机齿轮箱的研究虽然也取得了不少突破，但就国外而言还是存在了不少差距，很多部件还是依靠国外进口。所以我国应该继续跟进风机齿轮箱的科研进度，争取掌握成熟技术。
本次设计的主体是风力发电机的增速器齿轮箱，通过查阅资料选取适当的参数，并通过计算、分析、制图来逐步完成所有的设计内容。
1）通过查阅资料来确定齿轮箱的整体结构，拟定传动方案并进行传动比的分配与各传动组参数的确定；
2）通过运算来选取并确定各级的齿轮所有参数，例如模数、齿数这类;
3）对行星齿轮的传动过程所受力进行分析并依据所查标准进行强度校核，确保能够切合安全规定。
4）运用CAD软件进行制图。
5）通过Pro/E软件进行初步有限元分析。

Design of the wind turbine generator based on Pro/E
Abstract
As the name suggests, wind turbine is a mechanical device which use wind energy to generate electricity . In recent years, the development of wind turbine manufacturing industry is rapid. As the most important part in the wind power generator, wind turbine gearbox has won the world’s attention in it’s research and development. Many western countries have mastered lots of core technologies. However, in our country, although the research of wind turbine gearbox has many breakthroughs, there is still a big gap compared with foreign countries, many component still rely on imports. Therefore, our country should continue to strengthen the research and progress of the gear box, and strive to master the key technology.
The subject of this design is wind turbine gearbox, through accessing to data to select and distribute the transmission ratio, and through the calculation, analysis, mechanical drawing to complete all the design.
1) By consulting the data to determine the structure of the gear box, then selecting the transmission ratio and distributing it and determine the parameters by calculation ;
2) To determine the parameters at all levels of the gear , such as modulus, tooth number and so on;
3) To make the force analysis of the planetary gear’s transmission and check the strength according to the standard, to ensure that the results meeting the requirements.
4) Using CAD software to make machine drawing.
5) Making easy finite element analysis by Pro/E software.
