蝸輪蝸桿減速器用于原動機和工作機或執(zhí)行機構(gòu)之間，起匹配轉(zhuǎn)速和傳遞轉(zhuǎn)矩的作用，在現(xiàn)代機械中應用極為廣泛。但其設(shè)計過程繁瑣、周期長、效率低；隨著科學技術(shù)和國民經(jīng)濟的發(fā)展，蝸輪蝸桿減速器的需求量越來越大，且對質(zhì)量提出了更高的要求，而采用傳統(tǒng)的設(shè)計方法己遠遠不能夠滿足技術(shù)發(fā)展的需要。
本課題運用強大的三維造型軟件Pro-E實現(xiàn)了減速器CAD中典型零部件的三維實體建模及裝配仿真。很好的體現(xiàn)了計算機輔助設(shè)計的優(yōu)越點，它高效，便捷的特點得到了淋漓盡致的發(fā)揮，不僅使計算，繪圖容易許多，也使零件的工藝設(shè)計輕松很多。
同時，準確的蝸桿還有利于進行后續(xù)的裝配或和使用，并能很好地體現(xiàn)出計算機靈活、快捷、方便的優(yōu)點，而且在參數(shù)化輸入時，界面有友好、方便的交互式對話框，這些都是傳統(tǒng)的設(shè)計方法所不具有的優(yōu)點。關(guān)鍵詞 蝸桿傳動 減速器 CAD 實體造型 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
