中文摘要
風(fēng)電產(chǎn)業(yè)的飛速發(fā)展促成了風(fēng)電裝備制造業(yè)的繁榮，風(fēng)電增速齒輪箱作為風(fēng)電機(jī)組的核心部件，倍受國內(nèi)外風(fēng)電相關(guān)行業(yè)和研究機(jī)構(gòu)的關(guān)注。但由于國內(nèi)風(fēng)電齒輪箱的研究起步較晚，技術(shù)薄弱，特別是兆瓦級風(fēng)電齒輪箱，主要依靠引進(jìn)國外技術(shù)。因此，急需對兆瓦級風(fēng)電齒輪箱進(jìn)行自主開發(fā)研究，真正掌握風(fēng)電齒輪箱設(shè)計(jì)制造技術(shù)，以實(shí)現(xiàn)風(fēng)機(jī)國產(chǎn)化目標(biāo)。
本文首先，根據(jù)風(fēng)電齒輪箱承受載荷的復(fù)雜性，對其載荷情況進(jìn)行了分析研究，確定齒輪箱的機(jī)械結(jié)構(gòu)。選取兩級行星派生型傳動方案，通過計(jì)算，確定各級傳動的齒輪參數(shù)。其次，對行星齒輪傳動進(jìn)行受力分析，得出各級齒輪受力結(jié)果。依據(jù)標(biāo)準(zhǔn)進(jìn)行靜強(qiáng)度校核，結(jié)果符合安全要求。最后，繪制CAD裝配圖，并構(gòu)建了Pro/E的三維模型。

Abstract
The rapid development of wind power industry has contributed to the prosperity of wind power equipment manufacturing industry, and the wind power growth gear box is the core component of the wind turbine, which has been paid much attention by domestic and foreign wind power related industries and research institutions. But because of the research of the domestic wind power gear box, the technology is weak, especially the MW level wind power gearbox, which mainly depends on the introduction of foreign technology. Therefore, it is urgent to carry out research on the development of the MW level wind power gear box, and the real master of the wind power gearbox design and manufacture technology, in order to achieve the localization of the wind turbine.
In this paper, according to the complexity of the load of wind turbine gearbox, the load condition is analyzed and studied, and the mechanical structure of gear box is determined. Select the two stage planetary transmission scheme, through the calculation, determine the gear parameters at all levels of transmission. Secondly, the stress analysis of the planetary gear transmission is carried out. According to the standard static strength check, the results accord with safety requirements. Finally, the CAD assembly drawing is drawn, and the 3D model of Pro/E is constructed.
Key words:Wind power; Growth gear box; Design; Verification
