摘要:本文詳細(xì)介紹了垂直軸風(fēng)力發(fā)電機(jī)組傳動系統(tǒng)的設(shè)計過程。 風(fēng)電傳動系統(tǒng)的設(shè)計需考慮風(fēng)輪慣性及發(fā)電機(jī)短路力矩及陣風(fēng)等的影響，需要有風(fēng)輪的載荷序列方能進(jìn)行設(shè)計，所以必須先設(shè)計出風(fēng)輪才有后面的一系列零部件。 風(fēng)力發(fā)電機(jī)組中的傳動系統(tǒng)主要功用是將風(fēng)輪在風(fēng)力作用下所產(chǎn)生的動力傳遞給發(fā)電機(jī)并使其得到相應(yīng)的轉(zhuǎn)速。通常風(fēng)輪的轉(zhuǎn)速很低，遠(yuǎn)達(dá)不到發(fā)電機(jī)發(fā)電所要求的轉(zhuǎn)速，必須通過傳動系統(tǒng)齒輪副的增速作用來實(shí)現(xiàn)。根據(jù)機(jī)組的總體布置要求，有時將與風(fēng)輪輪轂直接相連的傳動軸（俗稱大軸）與傳動系統(tǒng)合為一體，也有將大軸與傳動系統(tǒng)分別布置，其間利用漲緊套裝置或聯(lián)軸節(jié)連接的結(jié)構(gòu)，本設(shè)計選擇后一種方式，以便于作為傳動系統(tǒng)的增速箱的制造、安裝以及維護(hù)。 具體方案選擇一級直齒圓柱齒輪增速，結(jié)構(gòu)簡單，穩(wěn)定性高，維護(hù)方便。安裝結(jié)構(gòu)方面，傳動系統(tǒng)的輸入和輸出軸均與大軸平行，考慮到系統(tǒng)的功率負(fù)載不大，齒輪的轉(zhuǎn)速也比較低，可選擇脂潤滑，同時解決了齒輪箱側(cè)置會產(chǎn)生的漏油問題。 關(guān)鍵詞：垂直軸風(fēng)力發(fā)電機(jī)，傳動系統(tǒng)，增速
Abstract:This paper mainly introduces the transmission system of vertical axis wind turbo generator designing. The design of transmission system of vertical axis wind turbo generator should consider the inertia of the wind wheel， even the impact of short circuit moment of the motor and flatus， and it impossible without the data of wind wheel’s load. So the wind wheel must be designed before the following steps. The function of the transmission system is to transfer the power from the wind wheel to the generator and endow it a corresponding rev. Normally the rev of the wind wheel is quite low and can not satisfy the generator’s demand，so there must be a transmission system to raise the out-put rev[3]. According to the demand of layout of the generator， the main axis is either combine with the transmission system or separated and connect to the in-put axis of the gearbox with a coupling. In this case the latter project is adopted to make it easier to manufacture， install and maintenance. The detail idea is use a single stage straight toothed spur gear transmission. The advantages of the idea is to make the system simple， steady and easy to maintain. The output axis and input axis are parallel to the main axis. The power of the system is not so strong and the rev of the axises is not very high， so the system will lubricated with grease and at the same time solve the problem of oil leaking. Key words: vertical axis wind turbo generator， transmission system， speed-up
