But in the transmission part design, this design has chosen the synchronized band pulley and the drive is connected, thus transmission power.This article other also to in installment changing to the drum, the drag roll and the supporting roller part has carried on the choice design, simultaneously has also made the essential computation and the choice to other supporting facilities.This design mainly designs the reduction gear the structure, had determined the interior various transmission gear as well as axis each main parameter, as well as changes to the drum design, and has made the multianalysis to its principle of work.Key words：Reduction gear; Changes to the drum; Pressure roller; Supporting roller0目 錄摘要IAbstructII第1章 緒論11.1 前言11.1.1 背景介紹11.1.2 運(yùn)輸機(jī)簡(jiǎn)介11.1.3 食品提升皮帶機(jī)簡(jiǎn)介41.2 方案確定51.3 設(shè)計(jì)方案綜述6第2章 減速器結(jié)構(gòu)的設(shè)計(jì)72.1 電動(dòng)機(jī)的選擇72.1.1 選擇電動(dòng)機(jī)類型和機(jī)構(gòu)形式72.1.2 功率的計(jì)算72.1.3 電動(dòng)機(jī)功率的選擇72.2.4 確定電動(dòng)機(jī)的轉(zhuǎn)速82.2 計(jì)算傳動(dòng)裝置的總傳動(dòng)比和分配各級(jí)傳動(dòng)比82.2.1 總傳動(dòng)比82.2.2 分配各級(jí)傳動(dòng)比82.3 傳動(dòng)裝置的運(yùn)動(dòng)和動(dòng)力參數(shù)92.3.1 各軸轉(zhuǎn)速92.3.2 各軸的輸入功率92.3.3 各軸的輸入轉(zhuǎn)矩92.4 V帶的設(shè)計(jì)102.4.1 確定計(jì)算功率102.4.2 選擇帶型102.4.3 確定帶的基準(zhǔn)直徑和102.4.4 確定中心距a和帶輪的基準(zhǔn)長(zhǎng)度102.4.5 驗(yàn)算小帶輪上包角112.4.6 確定帶的根數(shù)112.4.7 確定預(yù)緊力112.4.8 計(jì)算帶傳動(dòng)在軸上的力122.4.9 誤差驗(yàn)算122.4.10 帶輪設(shè)計(jì)122.5 高速級(jí)齒輪設(shè)計(jì)122.5.1 選齒輪的類型、精度等級(jí)、材料及齒數(shù)122.5.2 按齒面接觸強(qiáng)度設(shè)計(jì)122.5.3 按齒根彎曲強(qiáng)度設(shè)計(jì)142.5.4 幾何尺寸計(jì)算152.5.5 驗(yàn)算162.5.6 齒輪結(jié)構(gòu)設(shè)計(jì)162.6 低速級(jí)齒輪的設(shè)計(jì)尺寸162.7 軸的設(shè)計(jì)172.7.1 初步確定軸的最小直徑172.7.2 軸的結(jié)構(gòu)設(shè)計(jì)182.8 軸的校驗(yàn)202.9 鍵的選擇與校核262.10 滾動(dòng)軸承的選擇與校核27第3章 間歇機(jī)構(gòu)293.1 槽輪機(jī)構(gòu)293.1.1 槽輪機(jī)構(gòu)的組成及工作特點(diǎn)293.1.2 槽輪機(jī)構(gòu)的類型及應(yīng)用293.1.3 槽輪機(jī)構(gòu)的運(yùn)動(dòng)系數(shù)及運(yùn)動(dòng)特性293.2 棘輪機(jī)構(gòu)30第4章 改向滾筒的設(shè)計(jì)314.1 改向滾筒的結(jié)構(gòu)設(shè)計(jì)314.2 改向滾筒軸的強(qiáng)度校核31第5章 改向壓輪的設(shè)計(jì)355.1 改向壓輪的結(jié)構(gòu)設(shè)計(jì)355.2 設(shè)計(jì)方案的比較與選擇365.3 輸送帶的跑偏處理375.4 拉緊裝置38第6章 托輥的設(shè)計(jì)406.1 托輥的類型406.2 托輥的設(shè)計(jì)計(jì)算41第7章 食品提升皮帶機(jī)的安裝和操作維護(hù)447.1 啟動(dòng)和停機(jī)447.2 食品提升皮帶機(jī)的維護(hù)447.3 食品提升皮帶機(jī)的安裝44結(jié)論46參考文獻(xiàn)47致謝48 第1章 緒 論1.1 前言1.1.1 背景介紹本課題來源于工程實(shí)際,屬于工程設(shè)計(jì)。帶式輸送機(jī)特別是提升運(yùn)機(jī)是當(dāng)代最為得力的輸送設(shè)備之一，在整個(gè)輸送機(jī)范疇中，它是應(yīng)用最為廣泛的一種設(shè)備。隨著國民經(jīng)濟(jì)的不斷發(fā)展,多種類型的工件傳送機(jī)廣泛的運(yùn)用于冶金、礦山、水泥、碼頭、化工、糧食等行業(yè)的各種場(chǎng)合。同時(shí)在各種場(chǎng)合對(duì)不同的工況所使用的工件傳輸機(jī)也不盡相同，近年來由于工件傳輸機(jī)的應(yīng)用范圍的擴(kuò)大，品種的增多以及質(zhì)量的不斷提高，對(duì)加工設(shè)計(jì)工件傳輸機(jī)提出了更高的要求，特別是在一些大型的流水線上，工件傳輸機(jī)承擔(dān)了很重要的工作任務(wù)。這些工件傳輸機(jī)要求傳輸距離和速度，精度比較高。為此各廠家為了根據(jù)自己的需要，出于經(jīng)濟(jì)性和戰(zhàn)略方向的考慮，自行設(shè)計(jì)結(jié)構(gòu)簡(jiǎn)單可靠，生產(chǎn)價(jià)格便宜的工件傳輸機(jī)。通過該設(shè)計(jì)能使學(xué)生將大學(xué)四年所學(xué)的知識(shí)能靈活的運(yùn)用于實(shí)踐。對(duì)于一個(gè)工程的整體設(shè)計(jì)有了更好的理解。有助于形成工程化的思想,對(duì)以后的設(shè)計(jì)打下很好的基礎(chǔ)。
