輪擺式單斗挖掘機(jī)驅(qū)動(dòng)橋設(shè)計(jì)

摘要：輪擺式單斗挖掘機(jī)適用于山體、斜坡等結(jié)構(gòu)復(fù)雜的環(huán)境工作，其最大的特點(diǎn)是將履帶換成四個(gè)獨(dú)立可活動(dòng)的擺臂，以到達(dá)挖掘機(jī)在惡劣環(huán)境中工作的可行性，輪擺式挖掘機(jī)擺臂驅(qū)動(dòng)橋承受了整個(gè)挖掘機(jī)的整體重量及工作和行進(jìn)時(shí)挖機(jī)的復(fù)雜受力情況，同時(shí)擺臂具有確定的兩個(gè)自由度的運(yùn)動(dòng)，結(jié)合以上特點(diǎn)本文主要介紹了擺臂驅(qū)動(dòng)橋鋼板沖焊橋殼總成、減速器總成及車輪制動(dòng)器總成、以及擺臂的連接部件滑動(dòng)軸承等相關(guān)驅(qū)動(dòng)橋結(jié)構(gòu)件的結(jié)構(gòu)特點(diǎn)，并對(duì)以上部件進(jìn)行了相關(guān)的設(shè)計(jì)及強(qiáng)度、剛度校核。關(guān)鍵字：輪擺式驅(qū)動(dòng)橋減速器平行四邊形擺臂滑動(dòng)軸承Summary：TheroundDouwithsingleputtypescoopsoutmachineisapplicabletothecomplicatedenvironmentworkofthestructures,suchasmountainbodyandslope...etc.Itsbiggestcharacteristicsistochangethetrackintofourindependencecanputofactivityarm.Scoopoutbyattainthepossibilitythatthemachineworksinthebadenvironment,Roundtheputtypeexcavationmachineputarmtodrivebridgetobearthewholewholeweightandworkwhichscoopoutmachinewithmarchforwarddigmachineofcomplicationsbesubjectedtoadintcircumstance,inthemeantimeputarmtohavetwosportofcertainfreedomdegree,combineanabovecharacteristicsorigintextmainlyintroducedtoputarmdrivebridgesteelplatebluntHanbridgehullalwaysbecome,deceleratemachinealwaysbecomeandthecarwheelsystemmoveamachinealwaysbecome,andputbrachialconjunctionparts*glide'sbearings*etc.relateddrivebridgestructurethestructurecharacteristicsofthepiece,andtoabovethepartscarriedonrelateddesignandstrength,justdegreeschoolpit.Keywords：RoundputtypeDrivebridgeDecelerateamachineGlidebearingsGlidebearingsGlidebearingsTheparallelogramputsarmGlidebearings目錄TOC\o"1-5"\h\z第一章緒論1L1概述11.2挖掘機(jī)設(shè)計(jì)思路概述11.2.1.步挖機(jī)在結(jié)構(gòu)形式和參數(shù)選擇21.2.2.其工作簡圖如圖1-2-1所示21.3挖掘機(jī)驅(qū)動(dòng)橋機(jī)構(gòu)件設(shè)計(jì)思路分析步驟41.3.1.根據(jù)挖掘機(jī)的工作方式確定其驅(qū)動(dòng)橋結(jié)構(gòu)43.2.確定平行可移式擺臂的結(jié)構(gòu)51.4小結(jié)7第二章挖掘機(jī)驅(qū)動(dòng)橋結(jié)構(gòu)設(shè)計(jì)81主要參數(shù)的選擇8利用經(jīng)驗(yàn)公式確定其它總體參數(shù)。82.1.2步挖機(jī)的行走機(jī)構(gòu),鏟斗挖掘時(shí)所克服的最大阻力計(jì)算92.2挖掘機(jī)驅(qū)動(dòng)橋擺臂整體設(shè)計(jì)92.2.1.挖掘機(jī)擺臂受力分析92.2.2.挖掘機(jī)驅(qū)動(dòng)阻力的計(jì)算102.2.3.挖掘機(jī)坡度阻力的計(jì)算112.2.4.挖掘機(jī)轉(zhuǎn)彎阻力的計(jì)算122.2.5.挖掘機(jī)擺臂受力總分析132.2.6擺臂剛度及強(qiáng)度校核132.2.7.梁的強(qiáng)度計(jì)算142.2.8.梁的剛度校核153本章小結(jié)17第三章驅(qū)動(dòng)橋接口端設(shè)計(jì)18驅(qū)動(dòng)橋與擺臂接口端圖示182.驅(qū)動(dòng)橋與擺臂接口端抗扭強(qiáng)度校核20第四章驅(qū)動(dòng)橋減速器設(shè)計(jì)211挖掘機(jī)驅(qū)動(dòng)橋內(nèi)減速器設(shè)計(jì)214.1.1.減速器齒輪設(shè)計(jì)214.1.2齒根彎曲強(qiáng)度驗(yàn)算234.2.減速器箱體尺寸設(shè)計(jì)254.2.1減速箱箱體設(shè)計(jì)254.2.2減速箱連接螺栓設(shè)計(jì)264.2.3減速器軸承的選擇計(jì)算262.4減速器的潤滑273聯(lián)軸器的選取27第五章挖掘機(jī)驅(qū)動(dòng)橋軸零件設(shè)計(jì)291挖掘機(jī)驅(qū)動(dòng)橋軸零件設(shè)計(jì)291.1輪胎支撐軸的設(shè)計(jì)與校核291.2軸的危險(xiǎn)截面的強(qiáng)度校核301
