摘要 摘要 隨著化石能源的過渡消耗以及其對環(huán)境帶來的嚴重影響，風能憑借其清潔、可循環(huán)利用等諸多優(yōu)點而越來越受到重視，各國都在積極開發(fā)利用本國的風能資源，中國也不例外。本文根據(jù)導師布置的畢設課題《小型風力發(fā)電機組動力結構設計》中的要求，探索小型風力發(fā)電機動力結構的設計。 主要研究結果如下: 1、 根據(jù)風力發(fā)電機葉片設計的經(jīng)典理論設計葉片的外形，利用三維建模軟件建立葉片的三維實體模型。 2、 根據(jù)設計需求，設計出了軸轂、支撐架等零部件，并利用Solidworks軟件建立了三維模型。 3、根據(jù)設計需求，設計出了變向器裝置，并合理地選擇了軸承、鍵等配套零部件。 關鍵詞：小型風力發(fā)電機；葉片；軸承。 Abstract With the consumption of fossil fuels and their serious impact on the environment, the wind energy with the advantages of clean and can be recycled for use is growing importance to many countries and they are actively developing and utilizing its wind resource, China is no exception. This paper is based on the requirements of The Power Conformation of Small Wind Turbine to explore the method for design and manufacturing process of small wind turbine using of composite materials. The main results achieved are as following: 1 .According to the classic theory of the wind turbine blade design and using 3D modeling software, the blade's 3-D solid model is established. 2. Based on the requirements of design ,the aim is to design some parts as bushing and brace, even more I should establish he blade's 3-D model using the software of Solidworks. 3. Based on the requirements of design, my aim is to select some parts just like axle-bearing, bond reasonably, and deign the apartment of transformer. Keywords: small wind turbine；blade；axle-bearing； II
