【正文】 本科畢業(yè)設(shè)計 題目名稱： 發(fā)動機(jī)翻轉(zhuǎn)拆裝臺設(shè)計 學(xué) 院： 專業(yè)年級： 學(xué)生姓名： 班級學(xué)號： 指導(dǎo)教師： 二 XXX 年六月十日 摘 要 I 摘 要 現(xiàn)在學(xué)校汽車發(fā)動機(jī)拆裝實習(xí) ， 是在簡易的鐵工作臺上通過人力翻轉(zhuǎn)對發(fā)動機(jī)進(jìn)行拆裝的 ， 拆裝起來費時、費力、效率低 ， 發(fā)動機(jī)支承不穩(wěn)還容易傾倒傷人 ， 而且在 拆裝過程中觀察發(fā)動機(jī)內(nèi)部結(jié)構(gòu)很不方便 。 即不能保證工件、工具、油、水不落地 ,也達(dá)不到衛(wèi)生清潔、安全、按時完成教學(xué)任務(wù)的基本要求 ,因此為保證教 學(xué)質(zhì)量而設(shè)計一臺供同學(xué)拆裝實習(xí)和維修的發(fā)動機(jī)拆裝臺是非常必要的 。 目前市場的發(fā)動機(jī)翻轉(zhuǎn)拆裝臺類型較多，但都不適于學(xué)校使用。我設(shè)計的發(fā)動機(jī)翻轉(zhuǎn)拆裝臺使用蝸輪蝸桿減速器控制的，減速器類型為 ZA 型阿基米德螺旋線的，蝸桿為單線型，傳動比為 1： 39，蝸桿輸入轉(zhuǎn)速 20r/min，蝸輪輸出轉(zhuǎn)速 180176。 /min。 在設(shè)計過程中嚴(yán)格 依據(jù)以下標(biāo)準(zhǔn)： 《機(jī)械零件設(shè)計手冊》 JTGD60－ 20xx 《機(jī)械設(shè)計基礎(chǔ)》 JTGD62－ 20xx 《機(jī)械制圖》 JTGD62－ 20xx 關(guān)鍵詞 ： 蝸輪；蝸桿 ； 減速器 ； 拆裝臺。 大學(xué)本科畢業(yè)設(shè)計 II Abstract Now the car engine dismantling and installing is on the table of iron by human overturned at is a waste of time, laborious and inefficient. It is also easy to dump and woun people if the support is unconvenient in the process of observation of the internal structure of the is no guarantee that the workpiece, tools, oil and water do not fall, and can not keep clean, safe, timely plete the tasks of the basic teaching requirements. In order to ensure the quality of teaching, it is very necessary to design a operate table for students dismantling and installing are many types of overturned operate tables in the current market. It is unfit for the overturned operate table that I designed controled by Worm Gear Reducer of the ZAreducer type spiral of Archimedes for a single type of worm. The transmission ratio is 1:39, the worm enter Speed is 20 r / min, Worm output speed is 180 176。 / min. In the design process in strict accordance with the following criteria: Mechanical parts Design Manual JTGD6020xx Mechanical design basis JTGD6220xx Mechanical drawing JTGD6220xx Key words: worm wheel cylindrical worm reducer dismantling and installing table Abstract III 目 錄 摘 要 ....................................................................................................................................... 1 Abstract ...................................................................................................................................
