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)計制造技術(shù)，以實(shí)現(xiàn)風(fēng)機(jī)國產(chǎn)化目標(biāo)。
本文設(shè)計的是兆瓦級風(fēng)力發(fā)電機(jī)組的齒輪箱，通過方案的選取，齒輪參數(shù)計算等對其配套的齒輪箱進(jìn)行自主設(shè)計。
首先，確定齒輪箱的機(jī)械結(jié)構(gòu)。選取一級行星派生型傳動方案，通過計算，確定各級傳動的齒輪參數(shù)。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。
其次，基于Pro／E參數(shù)化建模功能，運(yùn)用漸開線方程及螺旋線生成理論，建立斜齒輪的三維參數(shù)化模型。
然后，對齒輪傳動系統(tǒng)進(jìn)行了齒面接觸應(yīng)力計算。先利用常規(guī)算法進(jìn)行理論分析計算。

關(guān)鍵詞：風(fēng)力發(fā)電，風(fēng)機(jī)齒輪箱，結(jié)構(gòu)設(shè)計，建模

Abstract

The 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 gearbox for 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．
This paper takes the wind power。The independent design of the gearbox matching for the wind turbine has been carried out by selecting the transmission scheme and calculating the gear parameters。
Firstly, 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．The static strength check of tooth surface contact is implemented according to related standard．The result shows that it is accord with safety requirements．
Secondly, the helical gear parametric model is established based on involutes curve equation and generation theory of spiral line by using the function of parametric modeling in Pro／E．
Then, the tooth surface contact stress of the gear transmission is calculated．

Key Words：the wind power ，Gearbox for Wind Turbine；Structure Design；Parametric Modeling
