摘要：当前，我国还属于发展中国家，能源缺口与环境污染问题都是目前急需解决的发展现状。而风能因其清洁性与可再生性而成为我国首选新能源之一。而在风能的利用中，风力发电则是主要的利用形式。传统的水平风力发电机由于造价高、维护贵、体积大等特点而存在许多方面的限制。随着科学技术的发展进步，垂直风力发电机的实现成为了可能，且弥补了风力发电的空白领域，使得风力发电成为目前最有发展前景的发电方式之一。

垂直风力发电机早在几个世纪之前，也就是风力发电这个概念在提出并且发明风力发电机之时就提出过。从历史上来看，古代的磨坊也根据地区的不同有着水平布置的风车与竖直布置的风扇。而且长久以来的经验也表明两者各有不同优点，然而之所以目前水平风力发电机大行其道，而垂直风力发电机却鲜有踪迹是因为垂直的叶片涉及到了许多空气动力学知识与复杂的函数计算。这些都不是当时的发展程度所能轻易完成的。而如今一切的条件都已经成熟，市面上也有了几款成熟的叶片设计，不过由于起步较晚，这方面的成果比较少，尤其是传动方面成熟稳定的方案，所以本次论文就着重于集中解决和攻克这些问题与难关。

而由于市场中垂直风力发电机的叶片种类和尺寸各异，且各地区的天气及风速情况各不相同。故此在设计的初级阶段就设计了多种传动方案，并在分析各个不同方案的优缺点之后在其中找出最适合的优选传动设计方案。而这其余的方案也可作为其余设计的参考，只是在本次论文中不给予大篇章幅来计算讨论。然后在这基础之上进行分配各级的传动比及确定齿数、模数等相关参数。在设计完齿轮箱的齿轮、轴及轴承后再充分地利用软件有限元分析的现代技术进行相关参数的校核以及箱体等选用设计问题，完成传动结构方案设计。

Design of Transmission Structure for Wind Turbine

Abstract：At present, China is still a developing country, and the energy gap and environmental pollution problems are currently urgently needed. Wind energy has become one of China's first choice of new energy because of its cleanliness and reproducibility. In the use of wind energy, wind power is the main form of utilization. Traditional horizontal wind turbines have many limitations because of high cost, high maintenance, and large volume. With the development of science and technology, the realization of vertical wind turbines has become possible, and made up for the blank areas of wind power generation, making wind power generation one of the most promising power generation methods.

The concept of vertical wind turbines was proposed centuries ago, namely the concept of wind power generation when it was proposed and invented. Historically, ancient mills have horizontally arranged windmills and vertical fans, depending on the region. And long-term experience also shows that the two have different advantages, but the current level of wind turbines is popular, and vertical wind turbines are rarely traced because vertical blades involve a lot of aerodynamic knowledge and complex function calculations . None of this was easily accomplished at the time of development. Now all the conditions are ripe, and there are several mature blade designs on the market. However, due to the late start, the results in this area are relatively small, especially the mature and stable transmission solutions, so this paper focuses on Solve and overcome these problems and difficulties.

However, due to the different types and sizes of vertical wind turbine blades in the market, the weather and wind speed in each area are different. Therefore, in the initial stage of the design, a variety of transmission solutions were designed, and after analyzing the advantages and disadvantages of each of the different solutions, the most suitable optimal transmission design was found. The rest of the plans can also serve as a reference for the rest of the design. However, this paper does not give a large chapter to calculate the discussion. Then, on this basis, the transmission ratios at various levels and the related parameters such as the number of teeth and modulus are determined. After designing gears, shafts and bearings of the gear box, the modern technology of software finite element analysis is fully utilized to check the relevant parameters and select design problems of the box and so on, to complete the design of the transmission structure.
