-I-摘要目前，在我國直接為煤礦生產(chǎn)服務(wù)的鉆機，百分之八十以上在井下從事作業(yè)?，F(xiàn)有的鉆機所呈現(xiàn)的功率低、主軸轉(zhuǎn)速慢、鉆進速度慢、運輸不方便、勞動強度大工作效率低等缺點越來越明顯。本次設(shè)計就是對50米鉆機進行改進。改進后該鉆機具有以下優(yōu)點，外型尺寸小，重量輕；易于解體，適應(yīng)工作場地的更換；鉆機轉(zhuǎn)速快鉆進速度比以往都要快；用液壓卡盤固定鉆桿，盡可能的實現(xiàn)自動化，提高了效率，減輕了疲勞強度。TXU-50型鉆機主要由回轉(zhuǎn)器、給進機構(gòu)、變速箱、鉆機操縱機構(gòu)把手組成，配有控制測量儀表和其他一些輔助裝置。設(shè)計中著重考慮電機的選擇、變速箱和液壓系統(tǒng)的設(shè)計。提高電機功率從而提高主軸轉(zhuǎn)速，改進變速箱結(jié)構(gòu)從而減小體積，以便運輸。關(guān)鍵詞：鉆機電機回轉(zhuǎn)器機械傳動系統(tǒng)液壓系統(tǒng)-II-AbstractCurrent,producetodrillthemachineministrantlyforthecoalminedirectlyintheourcountry,80%underthewellisengagedinthehomeworkabove.theexistingdrillingmachinepresentsthepowerlow,themainaxlerotationalspeedslow,sneaksinthespeedslowly,thetransportationnotconvenient,thelaborintensitybigworkingefficiencylowandsoontheshortcomingismoreandmoreobvious.Thisdesignisaimsat50metersdrillingmachinessomeimprovements.Belowtheimprovementthisdrillingmachinehasthemerit.Theoutlooksizesmall.Theweightislight.Easytodisintegrate,adaptionworkingareareplacement.Thedrillingmachinerotationalspeedquicklysneakedinthespeedformerlyalltohavetobequickerthan；Withthehydraulicpressureqiapanfixeddrillrod,theasfaraspossiblerealizationautomation,enhancedtheefficiency,reducedthefatiguestrengthTheTXU-50drillingmachinemainlybythegyrator,givestheorganization,thegearbox,thedrillingmachinecontrolmechanismandsooniscomposedthehand,hasthemonitorandothersomeauxiliaryunit.Inthedesignconsiderstheelectricalmachineryemphaticallythechoice,thegearboxandthehydraulicsystemdesign.Enhancestheelectricalmachinerypowerthustoenhancethemainaxlerotationalspeed,improvesthegearboxstructurethustoreducethevolume,inordertotransports.Keyword:DrillingmachineMotorCircumgyratewareTransmissionsystemHydraulicsystem-III-目錄摘要IAbstractII第1章緒論11.1鉆機的發(fā)展11.2項目的研究意義11.3國內(nèi)外科技現(xiàn)狀11.4項目創(chuàng)新之處21.5鉆機的工作原理2第2章鉆機的總體設(shè)計42.1鉆機的特點42.1.1各部分結(jié)構(gòu)設(shè)計42.1.2鉆機的外形特點42.1.3鉆機的總體設(shè)計方案5第3章鉆機的技術(shù)特點63.1鉆機的主要參數(shù)63.2回轉(zhuǎn)器的主要參數(shù)63.3電動機參數(shù)63.4油泵參數(shù)63.5水泵參數(shù)6第4章動力機的選擇74.1回轉(zhuǎn)器轉(zhuǎn)桿及破碎巖石所需功率的計算74.2給進油缸所需功率的計算84.3動力機功率的確定9第5章機械傳動系統(tǒng)的計算105.1主要運動參數(shù)的選擇105.2變速箱的設(shè)計計算115.2.1變速箱內(nèi)各齒輪的主要參數(shù)和材料115.2.21Z、2Z齒輪對的強度較核115.2.33Z、4Z齒輪對的強度較核135.2.45Z、6Z齒輪對的強度較核155.3回轉(zhuǎn)器的設(shè)計175.3.1回轉(zhuǎn)器的結(jié)構(gòu)特點17-IV-5.3.2零部件的強度與壽命計算175.4軸的計算195.4.1軸II的計算195.4.2軸I的計算235.5軸承的計算265.6軸承的潤滑265.7軸承的密封裝置275.8密封與潤滑28第6章液壓系統(tǒng)的設(shè)計306.1鉆機液壓系統(tǒng)的作用30
