【正文】 月初到現(xiàn)在，結(jié)合自己的畢業(yè)設(shè)計(jì)進(jìn)行了針對(duì)性的畢業(yè)實(shí)習(xí)。 通過畢業(yè)設(shè)計(jì)的訓(xùn)練，提高了以下能力：通過設(shè)計(jì)加強(qiáng)對(duì)皮帶運(yùn)輸機(jī)的認(rèn)識(shí) 。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 parameter39。 本文還分析了國(guó)內(nèi)外帶式輸送機(jī)的現(xiàn)狀及發(fā)展趨勢(shì)，說明在現(xiàn)代高科技發(fā)展的情況下，帶式輸送機(jī)的發(fā)展?jié)摿€是很大的。 隨著國(guó)民經(jīng)濟(jì)的發(fā)展，帶式輸送機(jī)的應(yīng)用越來越廣泛。 近年來，隨著工業(yè)技術(shù)的發(fā)展，帶式輸送機(jī)也不斷朝著大運(yùn)量、長(zhǎng)距離、大傾角、高帶速、 投資費(fèi)用少、運(yùn)營(yíng)費(fèi)用低、工作可靠、維護(hù)方便等 方向發(fā)展，對(duì)其設(shè)計(jì)技術(shù)的要求也越來越高。 本文研究了一般固定式帶式輸送機(jī)的設(shè)計(jì)理論，并根據(jù)所設(shè)計(jì)的要求再結(jié)合目前國(guó)內(nèi)的目前的技術(shù)要求組裝了一套傾角為 0 度的固定式帶式輸送機(jī)，說明了這套設(shè)計(jì)符合設(shè)計(jì)參數(shù)的要求 關(guān)鍵字： 輸送機(jī) 發(fā)展 結(jié)構(gòu)原理 計(jì)算和校核 ii 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 landform39。s. iii Key words: Transport machine Develop Structure principle Secretly scheme against and school core 目錄 前 言 .........................................................1 1 緒 論 .......................................................3 皮帶運(yùn)輸機(jī)的概況 ......................................3 皮帶運(yùn)輸機(jī)的發(fā)展史 ...............................3 皮帶運(yùn)輸機(jī)基本結(jié)構(gòu) ...............................4 礦用皮帶運(yùn)輸機(jī)各機(jī)型介紹 ........................4 皮帶運(yùn)輸機(jī)的發(fā)展趨勢(shì) .................................10 國(guó)外皮帶運(yùn)輸機(jī)技術(shù)的現(xiàn)狀 ........................10 國(guó)內(nèi)皮帶運(yùn)輸機(jī)技術(shù)的現(xiàn)狀 ........................11 國(guó)內(nèi)外皮帶運(yùn)輸機(jī)技術(shù)的差距 ......................12 煤礦皮帶運(yùn)輸機(jī)技術(shù)的發(fā)展趨勢(shì) ...................16 2 皮帶運(yùn)輸機(jī)的設(shè)計(jì)計(jì)算 .......................................18 已知原始數(shù)據(jù)及 工作條件 ................................18 輸送帶寬度的確定及核算 ............................19 帶速的確定 ......................................19 帶寬的確定 ......................................20 輸送帶寬度的核算 ................................22 圓周驅(qū)動(dòng)力 ............................................22 計(jì)算公式 ........................................22 主要阻力計(jì)算 ....................................24 特種主要阻力計(jì)算 ................................26 特種附加阻力計(jì)算 ................................26 傾斜阻力計(jì)算 ....................................28 傳動(dòng)功率計(jì)算 ..........................................28 傳動(dòng)滾筒軸功率（ AP ）計(jì)算 .......................28 電動(dòng)機(jī)功率計(jì)算 ..................................29 輸送帶張力計(jì)算 ........................................30 阻力計(jì)算 ........................................30 輸送帶不打滑條件校核 ............................33 輸送帶下垂度校核 ................................34 輸送帶強(qiáng)度校核計(jì)算 ..............................35 拉緊力計(jì)算 ............................................35 傳動(dòng)滾筒 ,改向滾筒合張力計(jì)算 ...........................36 iv 改向滾筒合張力計(jì)算 ..............................36 傳動(dòng)滾筒合張力計(jì)算 ..............................37 傳動(dòng)滾筒最大扭矩計(jì)算 .................................37 3 皮帶運(yùn)輸機(jī)的傳動(dòng)原理 .......................................38 膠帶的摩擦傳動(dòng)原理 ....................................38 傳動(dòng)裝置的牽引力 ......................................40 4 傳動(dòng)裝置的選用與設(shè)計(jì) .......................................43 電機(jī)的選用 ...........................................43 減速器的選用 .........................................45 傳動(dòng)裝置的總傳動(dòng)比 ..............................45 液力偶合器 ...........................................48 聯(lián)軸器 ...............................................50 5 皮帶運(yùn)輸機(jī)部件的選用 .......................................56 輸送帶 ...............................................39 輸送帶的分類： ..................................39 輸送帶的連接 ....................................42 傳動(dòng)滾筒 .............................................43 傳動(dòng)滾筒的作用及類型 ............................43 傳動(dòng)滾筒的選型及設(shè)計(jì) ............................43 傳動(dòng)滾筒結(jié)構(gòu) ....................................49 傳動(dòng)滾筒的直徑驗(yàn)算 ..............................53 拉緊裝置 .............................................54 制動(dòng)裝置 .............................................66 裝載裝置 ..............................................54 清掃裝置 .............................................55 機(jī)架 ..................................................58 改向滾筒 ..............................................59 驅(qū)動(dòng)裝置架 ............................................61 總 結(jié) .......................................................63 致 謝 .......................................................64 參考文獻(xiàn) .....................................................65 河南理工大學(xué)萬方科技學(xué)院本科畢業(yè)論文 1 前 言 四年的大學(xué)生活即將結(jié)束，我們這些面臨畢業(yè)的大學(xué)生進(jìn)行為期兩個(gè)月的畢業(yè)設(shè)計(jì)，我感受頗深。通過此次的設(shè)計(jì)來檢查自己大學(xué)四年
