I摘要刮板輸送機(jī)是為采煤工作面和采區(qū)巷道運(yùn)煤的機(jī)械。它具有適應(yīng)性好，協(xié)作性好，耐磨性好，可彎曲性好，機(jī)身的強(qiáng)度和剛度高，能承受碰撞和沖擊等優(yōu)點(diǎn)，成為綜采設(shè)備中最主要的設(shè)備之一，是煤炭裝運(yùn)的第一個(gè)環(huán)節(jié)，在很大程度上決定了采煤工作面的生產(chǎn)能力和效率。主要對(duì)邊雙鏈型刮板輸送機(jī)機(jī)頭傳動(dòng)部進(jìn)行設(shè)計(jì)。整體式鏈輪組件在運(yùn)轉(zhuǎn)過程中經(jīng)常存在維修不便的問題，經(jīng)常拆卸影響傳動(dòng)裝置的可靠性。針對(duì)這一問題，本設(shè)計(jì)將鏈輪組件設(shè)計(jì)為剖分式。對(duì)于刮板輸送機(jī)的其他部件如機(jī)頭架、過渡槽、鏈輪、閘盤緊鏈器等，綜合已有的多種結(jié)構(gòu)進(jìn)行最佳設(shè)計(jì)，進(jìn)而完成輸送機(jī)的整體結(jié)構(gòu)設(shè)計(jì)。從電動(dòng)機(jī)的選擇開始設(shè)計(jì)，經(jīng)減速器設(shè)計(jì)、鏈輪組件設(shè)計(jì)、閘盤緊鏈器的選擇，最終確定機(jī)頭部整體結(jié)構(gòu)。關(guān)鍵詞刮板輸送機(jī)鏈輪減速器機(jī)頭部IIAbstractScraperconveyorforthecoalfaceandthecoalminingarearoadwaymachinery.Ithasagoodadaptability,collaborationandgood,wearresistance,andcanbendagoodbodyofhighstrengthandstiffness,canwithstandtheimpactofthecollisionandtheadvantagesofafullymechanizedcoalminingequipmentinoneofthemostimportantequipment,coalTheshipmentofthefirstsession,toalargeextentdeterminethecoalfaceofproductioncapacityandefficiency.Mainlyontheedgeofdouble-strandednosescraperconveyortransmissionofthedesign.-Sprocketcomponentintheoverallfunctioningoftheprocessofinconveniencetotheregularmaintenanceofexistingproblems,oftenthedemolitionoftheimpactoftransmissionreliability.Inresponse,thedesignofcomponentsdesignedtobesprocket-stylesubdivision.Thescraperconveyorcomponentssuchasthenoseoftheotherplanes,thetransitionslot,sprocket,thegatewastightchain,etc.,haveintegratedthebestdesignforavarietyofstructures,therebycompletingtheoverallstructureofconveyordesign.Motorstartfromthechoiceofdesign,thereducerdesign,sprocketcomponentdesign,gate-tightchainschoice,ultimatelydeterminetheoverallstructureofthehead.KeywordsscraperconveyorsprocketreducermachineheadIII目錄摘要.IAbstract.II第1章緒論.11.1國(guó)內(nèi)外發(fā)展情況.11.1.1國(guó)外刮板輸送機(jī)發(fā)展概況.11.1.2我國(guó)刮板輸送機(jī)發(fā)展現(xiàn)狀.11.1.3我國(guó)刮板輸送機(jī)的技術(shù)改進(jìn)方向.21.2研究目的和意義.31.3設(shè)計(jì)方案.3第2章電動(dòng)機(jī)和液力耦合器的選擇計(jì)算.62.1運(yùn)行阻力計(jì)算和驅(qū)動(dòng)電動(dòng)機(jī)選擇.62.1.1運(yùn)行阻力計(jì)算.62.1.2電動(dòng)機(jī)的選擇.92.2液力耦合器的選擇.10第3章減速器的設(shè)計(jì)計(jì)算.123.1傳動(dòng)比的分配和傳動(dòng)效率的選擇.123.1.1傳動(dòng)比的分配.123.1.2傳動(dòng)效率的選擇.123.2傳動(dòng)裝置的運(yùn)動(dòng)和動(dòng)力參數(shù)計(jì)算.133.2.1各軸轉(zhuǎn)速的計(jì)算.133.2.2各軸輸入功率的計(jì)算.143.2.3各軸輸入轉(zhuǎn)矩的計(jì)算.143.3錐齒輪傳動(dòng)的設(shè)計(jì).153.3.1選精度等級(jí)、材料及齒數(shù).153.3.2按接觸強(qiáng)度進(jìn)行初步設(shè)計(jì).153.3.3幾何尺寸的計(jì)算.163.3.4校核接觸強(qiáng)度.193.3.5齒根彎曲強(qiáng)度校核.223.4斜齒齒輪傳動(dòng)設(shè)計(jì).24IV3.4.1精度等級(jí)、材料及齒數(shù)確定.243.4.2按齒面接觸強(qiáng)度設(shè)計(jì).243.4.3按齒根彎曲疲勞強(qiáng)度設(shè)計(jì).273.4.4幾何尺寸計(jì)算.283.5直齒齒輪傳動(dòng)設(shè)計(jì).293.5.1選定精度、材料及齒數(shù).293.5.2按齒面接觸強(qiáng)度設(shè)計(jì).293.6軸的設(shè)計(jì).333.6.1軸的材料選擇和最小直徑估算.333.6.2軸的結(jié)構(gòu)設(shè)計(jì).343.6.3軸的校核.373.7鍵的選擇和校核.423.8滾動(dòng)軸承的選擇與校核.433.8.1滾動(dòng)軸承的選擇.433.8.2滾動(dòng)軸承的校核.44第4章鏈輪組件的計(jì)算及閘盤緊鏈器的選擇
