西安文理学院机械电子工程系本科毕业设计(论文)题目现场在线加工技术研究专业班级08级机电2班学号08102080239学生姓名王亚妮指导教师张长弓设计所在单位西安文理学院2012年5月现场在线加工技术研究摘要大型旋转设备由于各种原因经常发生轴颈拉伤事故,关键部件损伤维修是一个世界性难题,针对大型旋转机械转子轴颈损伤修复,一般情况下需要将机组打开,转子吊出,拆除叶轮,然后采用激光熔覆修复后机械加工,或直接采用机械加工方式修复。设计一套随行加工工装,在工装上安装加工刀具,利用转子轴颈相邻完好的部位定心,使工装围绕轴颈中心旋转,从而达到加工轴颈的目的。这种加工方式不用拆除叶轮,可以在现场实现轴颈加工,转子修理周期短,成本低,效率高,并保持与原轴颈的同轴度。通过对大量现场维修实施过程的了解,掌握现行的维修方法,为了节省时间,降低成本,维修安全,设计一套现场随行在线加工工装,方便在线维修,适用不同的现场,不同轴颈,灵活性强。关键字现场在线维修轴颈损伤激光熔焊在线加工工装TheOnlineProcessingTechnologyResearchAbstractLargerotatingequipmentforvariousreasonsoftenjournalofinjuryaccidentsinthemaintenanceofkeycomponentsofinjuryisaworldwideproblem,damagerepair,forlargerotatingmachineryrotorjournalusuallyyouneedtoopentheunit,therotorhangingout,removaloftheimpeller,andlasercladdingrepairmachiningormachiningtorepair.Asetofaccompanyingprocessingtooling,machiningtoolinstalledinthetooling,theuseofrotorjournaladjacentintactpartscenteringtoolingaroundtherotationofthejournalcenter,soastoachievethepurposeofprocessingthejournal.Thisprocessingmethodsdonothavetoremovetheimpeller,journalprocessinginthefield,rotorrepaircycleisshort,lowcost,highefficiency,andtomaintainconcentricitywiththeoriginaljournal.Understandingoftheimplementationprocessthroughalargenumberoffieldmaintenance,masterofthecurrentmaintenancepractices,inordertosavetime,reducecosts,maintenance,safety,accompanyingtheonlineprocessingoftoolingdesignasitetofacilitateonlinemaintenance,theapplicationofdifferentscene,differentjournal,flexiblestrong.KeywordOnsiterepairshaftneckdamageLastweldingprocessingtooling目录第一章绪论.....................................................................................................................................61.1现场在线加工研究的现状和发展.....................................................................................61.2课题的来源及意义.............................................................................................................81.2.1正确使用设备的意义..............................................................................................81.2.2正确维护设备的意义..............................................................................................81.2.3现场维修的意义......................................................................................................91.3本文主要研究内容.............................................................................................................91.3.1轴类零件表面磨损修复..........................................................................................9第二章总体结构概述...................................................................................................................112.1总体结构设想...................................................................................................................112.1.1结构设计目的........................................................................................................112.1.2结构设计初步方案................................................................................................112.2总体结构布局...................................................................................................................112.2.1各部分结构布局方案............................................................................................112.2.2初步设想效果图....................................................................................................12第三章动力部分...........................................................................................................................133.1电动机的选择简介...........................................................................................................133.1.1电动机的分类........................................................................................................133.2选择电动机.......................................................................................................................13第四章传动部分设计...................................................................................................................154.1传动方案的确定...............................................................................................................154.1.1链传动的优劣........................................................................................................154.1.2链传动的分类........................................................................................................154.1.3链轮的基本参数和主要参数................................................................................164.1.4链传动的传动比....................................................................................................185.1.5链的节距P和排数................................................................................................184.2传动结构...........................................................................................................................19第五章回转部分...........................................................................................................................215.1回转体总布局...................................................................................................................215.2回转体两边链轮结构介绍........
