皮帶運輸機總體及傳動設計

摘    要
 帶式輸送機是廣泛應用于煤炭、港口、建設、電廠等工業領域的連續輸送設備，它具有運輸效率高、運營成本低等優點。隨著國民經濟的發展，帶式輸送機的應用越來越廣泛。近年來，隨著工業技術的發展，帶式輸送機也不斷朝著大運量、長距離、大傾角、高帶速、投資費用少、運營費用低、工作可靠、維護方便等方向發展，對其設計技術的要求也越來越高。 為適應地形的要求，用輸送帶輸送一定高度的帶式輸送機在很多方面有應用。本文著重討論了帶式輸送機的結構原理、傳動原理、設計計算法則、運行阻力的計算、各點張力的計算等內容，以及各種計算參數的設計計算和校核，尤其對輸送帶的選用、托輥的選用進行了詳細的分析，使設計更加貼切接近實際問題。本文還分析了國內外帶式輸送機的現狀及發展趨勢，說明在現代高科技發展的情況下，帶式輸送機的發展潛力還是很大的。
 本文研究了一般固定式帶式輸送機的設計理論，并根據所設計的要求再結合目前國內的目前的技術要求組裝了一套傾角為0度的固定式帶式輸送機，說明了這套設計符合設計參數的要求

Abstract
 Taking style to transport machine is broad apply to industry field continuation such as coal , port construction, electric power plant transports equipment , that it has transportation is efficient , is in motion and do business cost low grade merit. The application with the development of national economy, taking style to transport machine is more and more broad. In recent years , with the development of industrial technology,the cost direction such as low , working reliably , defending to go to the lavatory taking style to transport machine bringing speed along also unceasingly to grand fortune amounts , long distance , big dip angle , height , investing in cost stopping being in motion and doing business, develops , designs that the technology request is also more and more high to the person. For the request adapting to landform's, use conveyer belt to transport certain altitude's taking style to transport machine having in many aspects applying. Content such as the main body of a book being emphasized having discussed structure principle , drive principle taking style to transport machine , being designing the calculation calculating a law , running resistance's , every tension calculation, calculating and proofreading the parametric design secretly scheming against as well as various, has carried out detailed analysis on the conveyer belt selecting and using , selecting and using supporting a roller especially , has used the problem designing especially appropriate approximation reality. The main body of a book has been analysed taking style to transport machine current situation and developing trend at home and abroad, the potential taking style to transport is still very big under explanation condition developing in modern high technology.
 The general stationary type the main body of a book has been studied takes style to transport the machine design theory , in the light of designed that together request still be tied in wedlock is at present domestic at present the technology has demanded assembling to copy a dip angle once for 14 degree of stationary type takes style to transport machine , the cover having explained this has designed that according with the request designing a parameter's.
