 摘要
 目前，螺旋輸送機的設計仍是依靠經驗公式計算，在經驗公式中許多參數的選擇是在一定范圍內憑經驗選取的，這使得螺旋輸送機的設計較落后，無法提高其設計水平和提高產品的性能。文中對螺旋輸送機進行了較全面論述，了解了螺旋輸送機的類型、發展現狀。闡明了螺旋輸送機的工作原理。并根據螺旋輸送機的工作原理、工作條件、輸送要求等設計螺旋輸送機。該螺旋輸送機用于煤粉的水平輸送，根據輸送量以及輸送路程設計出螺旋直徑，計算了螺旋功率以及根據功率選擇了電動機、減速器和聯軸器能較好地解決實際問題。最后對螺旋輸送機的安裝及平時保養做出了總結。整個設計對今后的設計工作將有實際指導意義和價值。該設計專用于運輸干燥煤粉，滿足一定運輸長度和運輸量的要求。采用傳統設計方法，根據運輸物料選擇LS型螺旋輸送機，由運輸量計算并校核得出螺旋葉片直徑D=500mm，轉速n=100r/min。根據這數據，依次計算選擇螺旋軸長度分配和螺旋軸鋼管大小和各段軸大小和相應的軸承。根據運輸量選擇行星減速器，傳動比為i=10。聯軸器分別選用了凸緣聯軸器。通的繪圖還有減速器的設計圖和主要零件圖。最后的校核驗算，得出的結論是我所設計的過長期的設計時間后，完成了相應的計算和校核，用電腦CAD繪圖完成了裝配圖的繪圖。最后的校核驗算，得出的結論是我所設計的LS500型的螺旋輸送機滿足設計要求，結構上不僵化采用參考書上的方案，更多的向市場上應用靠攏，最后完成了這次畢業設計任務。
 關鍵詞：螺旋輸送、傳動比、輸送量
 
 Abstract
Currently, the design of screw conveyor is still relying on the experience formula, the formula in the experience of many of the parameters of the option is selected within a certain range rule of thumb, which makes the design of screw conveyor has fallen behind, unable to raise design standards and improve product performance. In this paper, for a more comprehensive treatment of screw conveyor, screw conveyor of the type of understanding, development status. Illustrates the working principle of screw conveyor. Screw conveyor according to the working principle, working conditions, transportation requirements to design a screw conveyor. The level of the screw conveyor for coal transportation, according to throughput and transmission distance design spiral diameter, spiral computed power and power is selected based on motor, reducer and couplings can solve practical problems. Finally, screw conveyor installation and maintenance of peace and make a summary. The design of future design work will have practical significance and value. The design is dedicated to transport dry and coal, to meet a certain length and traffic transportation requirements. Traditional design method, according to the LS-type screw conveyor material selection, calculation and check of the transport screw blade diameter obtained D = 500mm, speed n = 100r/min. According to this data, followed by calculation of the length distribution and select the screw shaft screw shaft steel shaft size and the size of each segment and the corresponding bearings. Selected according to traffic planetary gear, transmission ratio i = 10. Were selected coupling flange coupling. There reducer through the design drawings and the main part drawing. Checking the final check, I have concluded that the design of the design over a long time after the completion of the corresponding calculation and verification, CAD drawing with a computer to complete the assembly map drawing. Checking the final check, I concluded that the LS500 is designed to meet the design requirements shaped screw conveyor, the structure is not rigid plan on using reference books, and more applications move closer to the market, and finally completed the Graduation task.
