畢業(yè)設(shè)計說明書（論文）中文摘要
無軸螺旋輸送機是一種不具有撓性牽引構(gòu)件的旋轉(zhuǎn)類型的物料輸送機械，是現(xiàn)代化生產(chǎn)和物流運輸不可缺少的重要機械設(shè)備之一。它的廣泛應(yīng)用對于提高勞動生產(chǎn)率，實現(xiàn)物料輸送過程的機械化和自動化，都具有重要的現(xiàn)實意義。
對于無軸螺旋輸送機，在工程設(shè)計及使用中還存在一些的缺陷，如參數(shù)選擇不合理等。目前，無軸螺旋輸送機的設(shè)計仍是依靠經(jīng)驗公式計算，在經(jīng)驗公式中許多參數(shù)的選擇是在一定范圍內(nèi)憑經(jīng)驗選取的，這使得無軸螺旋輸送機的設(shè)計較落后，無法提高其設(shè)計水平和提高產(chǎn)品的性能。
文中對無軸螺旋輸送機進行了較為全面論述，從了解無軸螺旋輸送機的類型、國內(nèi)外發(fā)展現(xiàn)狀。闡明了螺旋輸送機的工作原理。并根據(jù)無軸螺旋輸送機的工作原理、工作條件、輸送要求等設(shè)計――無軸螺旋輸送機。該無軸螺旋輸送機用于污泥的輸送，根據(jù)輸送量以及輸送路程設(shè)計出螺旋直徑，計算了螺旋功率以及根據(jù)功率選擇了電動機、減速器和聯(lián)軸器能較好地解決實際問題。

Title No axes of rotational conveyor driven institutions designed
Abstract
The screw conveyor is the necessary device of modern manufacturing and material fluid transportation. In order to reduce people's heavy physical work, to raise working productivity, to achieve material-conveying automation and mechanization, it possesses very important practical significance. It has already widely used in many country departments. Screw conveyors are used extensively in industry for conveying and elevating bulk materials over relatively short distances. They are very effective conveying devices for relatively free flowing bulk solids.
This paper comes from an investigation practical problem, which is put forward during the institute of construction machinery research makes some surveys. In fact, for screw conveyors, there are many problems in design, use, engineering, such as configuration design, non-reasonable in parameters choice and not convenience of acting machines. Thus there is often defect when materials are conveyed, for example, materials jam, noise, power wastage. These problems need urgent settlements.
The text of the screw conveyor in a more comprehensive discussion about the type of screw conveyor, the development of the status quo. To clarify the working principle of the screw conveyor. Screw conveyor in accordance with the working principle, working conditions, transportation requirements to design a screw conveyor. The screw conveyor for conveying the level of cement, according to throughput and transmission distance diameter spiral design, computing power, as well as a spiral in accordance with the power to choose a motor, reducer and coupling to solve practical problems.
At last, some research work is made about the influences of parameters during screw conveyors conveying bulks. This can direct later research work about screw conveyors design work, and has practical significance.
