变频调速钻机毕业设计

I摘要本文主要介绍了变频煤矿坑道钻机的结构设计，本次设计涉及到电动机的选型、减速器结构设计、液压卡盘设计、传动设计等方面的内容。主要设计内容是结合机械立轴式钻机与液压滑台式钻机的各自特点，将两种钻机的结构有机结合起来，采用变频调速电机作为动力机来实现无级调速使结构和操作得以简化的设计。电机动力通过联轴器和二级减速器传递到固定在主轴上的齿轮，从而使主轴带动钻具一起产生旋转运动，齿轮油泵输送出一定的压力，一方面用于打开液压卡盘，另一方面通过油路换向阀使给进油缸产生往复运动，还可以通过升降油缸使钻机升降到指定高度，各种供油不同时进行，给进油缸带动钻具往复运动。因此，此钻具即可旋转，又可给进，从而完成钻进任务，在煤矿用坑道钻机设计领域进行了一次有意义的探索，对工程实践也具有深远意义。关键词：变频电机；液压滑台；机械立轴；减速箱；液压卡盘IIAbstractThistextmainlyintroducedtobecomerepeatedlythecoalmineundergroundtunneldrillthestructuredesignofmachine,thisdesigninvolveschoosingofelectricmotortype,deceleratethemachinestructuredesign,hydrauliccarddishdesignandspreadthecontentsofdesignetc..Maindesigncontentsiscombineamachinetosignastalktypetodrillaslipperysettypeofmachineandhydraulictodrillmachineofrespectivelycharacteristics,twokindsofstructuresthatdrillmachinetheorganicknotputtogether,adoptionbecomerepeatedlyandadjustsoontheelectricalengineeringisapowermachinetocarryouthavenotheclassadjusttosoonmakethedesignsthatstructureandoperationcansimplify.Theelectricalengineeringpowerpassesalliedstalkmachineandsecondclassdecelerationmachinedeliverfixedlyinthewheelgearontheprincipalaxisandthusmakeprincipalaxisarousetodrilltogethercreationrevolvesport,thewheelgearoilpumptransportsacertainpressureandisontheotherhandusedforopeninghydrauliccarddishandontheotherhandchangethroughanoilroadtomaketogiveintotowardthevalveanoilurnthecreationbackandforthexercise,canalsopasstoascendanddescendanoilurntomaketodrillmachineriseandfalltoarriveappointedhigh,variousprovideoildifferentcarryon,arouseforoilurntodrillbackandforthsport.Therefore,thisdrillstorevolve,cangiveintoagainandcompletetodrillintoataskthusanddrillamachinedesignwiththeundergroundtunnelinthecoalminetherealmcarriedonameaningfulquestandalsohadprofoundmeaningtotheengineeringfulfillment.Keyword：Becomerepeatedly；electricalengineering；Thehydraulicslipsaset；Themachinesignsstalk；DecelerationboxHydrauliccarddishIII目录摘要.....................................................................................................................IAbstract.................................................................................................................II第1章绪论........................................................................................................11.1课题背景...............................................................................................11.2矿用坑道钻机发展现状及存在的问题...............................................11.2.1矿用坑道钻机领域的发展现状................................................11.2.2存在的问题................................................................................21.3本文设计的内容...................................................................................3第2章矿用坑道变频钻机结构总体设计........................................................42.1基本参数的确定....................................................错误!未定义书签。2.2设计方案的提出....................................................错误!未定义书签。2.3设计方案的评价与确定.......................................................................5第3章动力部分的设计计算............................................................................93.1电动机的确定.......................................................................................93.2液压泵的设计计算.............................................................................12第4章电气系统..............................................................................................144.1变频电机.............................................................................................144.1.1变频电机调速原理..................................................................144.1.2变频电机主要特点..................................................................154.2变频器.................................................................................................164.2.1变频器应用的特点..................................................................164.2.2逆变器控制电路中的保护电路..............................................164.2.3变频器控制回路的抗干扰措施..............................................17第5章减速箱的设计计算..............................................................................215.1传动系统的运动和动力学参数设计.................................................215.2高速级斜齿圆柱齿轮传动的设计说明.............................................215.2.1主要参数的确定......................................................................22IV5.2.2按齿面强度设计......................................................................235.2.3计算小齿轮分度圆直径..........................................................235.2.4按齿根弯曲强度设计..............................................................255.3低速级斜齿圆柱斜齿轮传动的设计说明.........................................275.3.1齿轮各参数的确定..................................................................275.3.2按齿面强度设计......................................................................285.3.3计算小齿轮分度圆直径..........................................................295.3.4按齿根弯曲强度设计..............................................................29第6章液压系统的设计计算..........................................................................336.1液压卡盘的设计计算..................................
