蝸輪蝸桿減速器用于原動(dòng)機(jī)和工作機(jī)或執(zhí)行機(jī)構(gòu)之間，起匹配轉(zhuǎn)速和傳遞轉(zhuǎn)矩的作用，在現(xiàn)代機(jī)械中應(yīng)用極為廣泛。但其設(shè)計(jì)過(guò)程繁瑣、周期長(zhǎng)、效率低；隨著科學(xué)技術(shù)和國(guó)民經(jīng)濟(jì)的發(fā)展，蝸輪蝸桿減速器的需求量越來(lái)越大，且對(duì)質(zhì)量提出了更高的要求，而采用傳統(tǒng)的設(shè)計(jì)方法己遠(yuǎn)遠(yuǎn)不能夠滿足技術(shù)發(fā)展的需要。
本課題運(yùn)用強(qiáng)大的三維造型軟件Pro-E實(shí)現(xiàn)了減速器CAD中典型零部件的三維實(shí)體建模及裝配仿真。很好的體現(xiàn)了計(jì)算機(jī)輔助設(shè)計(jì)的優(yōu)越點(diǎn)，它高效，便捷的特點(diǎn)得到了淋漓盡致的發(fā)揮，不僅使計(jì)算，繪圖容易許多，也使零件的工藝設(shè)計(jì)輕松很多。
同時(shí)，準(zhǔn)確的蝸桿還有利于進(jìn)行后續(xù)的裝配或和使用，并能很好地體現(xiàn)出計(jì)算機(jī)靈活、快捷、方便的優(yōu)點(diǎn)，而且在參數(shù)化輸入時(shí)，界面有友好、方便的交互式對(duì)話框，這些都是傳統(tǒng)的設(shè)計(jì)方法所不具有的優(yōu)點(diǎn)。關(guān)鍵詞 蝸桿傳動(dòng) 減速器 CAD 實(shí)體造型 裝配仿真

Title On the basis of the design of worm decelerator of CAD technology
Abstract
Worm decelerator is used between motor and implement mechanism, it takes an effect as matching rotate speed and transferring torque, and is used in modern machine extensively. But its design takes long times and great eforts with low designing efficiency; with development of science and technology and national economy, not only the requirement of worm decelerator is in larger and larger number, but also in higher and higher quality. Traditional methods of design are far beyond the requirement in development of technolog.
This paper is using the strong three-dimensional model software Pro-E to relize the three-dimensional solid modeling and assembly simulation of typical parts.It have very, high-efficient and fine embodiment some superiority of CAD.The convenient characteristic has got thorough full play , not only is it calculate to make, drawing easy a lot of, make technological design a lot easily of part.
At the same time, the accurate pole of snail still is advantageous to carrying on the follow-up assemble or and usage, and can nicely the body appears the vivid, fast and convenient advantage of calculator, and at the parameter turns the importation, the interface contain amity, hand over conveniently with each other the type dialog box, these are all traditional design method not have of advantage.


Keywords Spread to move of snail pole, Decelerator, CAD
