摘要这篇论文设计的是打桩机起重装置。它集机械设计最新理念、铸造工艺最新技术及CAD、CAM于一身，是将最新设计技术、CAD、CAM应用于实际的一个实例。文中涉及了蜗杆减速器和卷筒装置的设计、计算和校核，以及后期三维建模的相关内容。将蜗杆减速器应用于起重装置不仅提高了工作的可靠性，也大大提高了工作效率和经济效益。蜗杆减速器以其传动平稳，无噪声，结构紧凑，可以自锁等优点在起重装置及传动装置中得到了广泛的应用。在该系统中，选用的是单级蜗杆减速器。单级蜗杆减速器机构简单，易于设计，设计基础和经验丰富，且可以自锁，与其配套的附件容易买到。卷筒结构设计的好坏决定着整个系统性能的优劣。该起重装置采用了最新的结构，并在铸造上采用了最新的工艺来提高卷筒的强度、硬度和耐磨性。该系统能安全可靠地控制钢丝绳的牵引长度、速度，并能够实现作业中的自锁。论文中主要包括了减速器设计及计算和卷筒设计部分，并结合图表作了充分的讲解。关键词打桩机；起重装置；减速器；卷筒全套图纸，加527953900DesignofcarreduceranddrumcranepilingAbstractItisaboutthedrawequipmentofdrill-machineinthispaper.Itconcentratesthelatestmechanicaldesignconcepts,castingtechniquesandthelatesttechnologyofCAD/CAM.Thethesisisanexampleoftheapplicationoftheory.Itconcludesthedesign，calculationandcheckingoutofthewormgearsspeedreducerandthereelsystem,aswellasthenextthree-dimensionalsimulation.Wormgearsspeedreducerwillnotonlyenhancetheworkforthereliability,butalsogreatlyenhancetheefficiencyandcost-effectiveness.Thewormgearsspeedreduceriswidelyapplicationindrivesystemandtransmissionsystembecauseofitssmoothness,thenon-noise,thestructuretightlypackedandtheabilityofauto-lock.Inaddition,thereelsystemisveryimportantinthedrawsystem,sogoodnessorbadnessofthedesignofitdirectlyhaveimpactontheperformanceofthewholesystem.Thisdrawequipmentappliesthelateststructure,andthelatestadvancesintechnologytoimprovereel’sintensity,hardnessandabrasionresistance.Inthissystem,thechoiceisthesingle-gradewormgearsspeedreducer.Single-gradewormgearsspeedreducerhasasimplestructure,easytodesign,foundationdesignandexperience,andhastheabilityofauto-lock,andit’ssupportingaccessoriesareeasytobuy.Thesystemcansafelyandstablycontrolthelength,speed,andtoachieveoperationalauto-locks.Thewholepaperconcludesthedesignandcalculationofthespeedreducerandthereelpart,andthree-dimensionalsimulationnarrative,combiningwithgraphicsandforms.KeywordsDrillMachine;DrawEquipment;SpeedReducer;Reel不要删除行尾的分节符，此行不会被打印目录摘要=1\*ROMANIAbstract=2\*ROMANIITOC\o"1-3"\h\z\uHYPERLINK\l"_Toc233943828"第1章绪论PAGER
