-1-摘要立体车库随着汽车工业的发展而兴起，它以节省占地面积、经济、安全等优点而深受社会的欢迎，具有广阔的发展前景。因此，我选择了设计一套立体车库的提升机构作为研究课题。本设计中重点研究了立体车库提升机构的机械传动系统。经过深入细致地分析、比较后，终于确定了一套有别于常规的方案。整套设备具有结构对称的特点，分别采用由四组驱动轮驱动钢丝绳同时提升载车箱体的四角作垂直上升、下降运动，驱动装置集中于下部，由一个双轴伸电动机做动力，经两个双输出轴减速器减速后，传动到驱动轮，驱动轮带动钢丝绳使提升系统的箱体部分能上下运动，实现运送车辆的目的。顶部仅设置有四个用作变向的支撑轮。这样设计既减轻了车库建筑施工中对顶层楼板的承载要求和安装施工中的劳动强度，提高了可靠性，同时又方便了平常的检修与维护。根据上述方案，绘制了本套立体车库的提升机构传动系统的总装配图以及驱动轮、传动轴等零件图共计六张。并对进行了详细的设计计算及强度校核。关键词：立体车库；机械传动；提升机构-2-AbstractWiththedevelopingofthemotoringindustry,thetridimensionalgarageappeared.Itwaswelcomedtotheconsumerswiththeadvantagesofsavingfloorspace、economy、andsecurityandsoon.Itwouldbewidelyappliedinthefuture.Thus,Ichoosed(selected)thetridimensionalgarage’stransmissionsystemasthesubjectofmystudy.Ichoosedtheliftingmechanism’stransmissionsystemofthegarageastheprimarypurpose.Afterindepthandparticularityanalysedandcompared,finally,Ihaveauniquestyleindesigningtheliftingmechanism.Thewholesetwassymmetricalinstructure.Itadoptedfourgroupsdrivingwheelmakesthecaseupanddowninthesametime.Thedrivingsetwasplacedunderthecase.Thesethasatwinshaftstretchdynamoasitspower,aftertwodoubleoutputshaftretarderslowdown,transmissiontodrivingwheelsowireropesbebroughtalongbythedrivingwheelmadehoistingsystem’casetendtoup-and-downmovementandrealizesthepurposeoftransportingcar.Thereareonlyfourbeamwheelempoliedasthedeflectingofthedirection,whichbeabletoalleviatethebearingrequireofthecopingfloorslabandlabourintensityininstalling,promotereliability,atthesametimeconvenienceinordinaryrepairworkandmaintenance.Onthebaseofforementionedscheme,Idrawnedlifting-3-mechanism’transmissionsystemoftridimensionalitygarageandassemblydrawingalongwithdrivingwheel、transmissionshaftandsoondrawingdetailedsumedtosixsheets.Andthencalculatedandverificatedthestrengthofthewholeset.Keywords:tridimensionalgarage;transmissionsystem;liftingmechanism-1-目录1.前论...........................................................11.1国内外立体车库的发展状况........................................11.2本设计的具体任务及其意义.......................................22.机械式停车库设备方案的确定........................................32.1机械式停车设备的功能及结构分析.................................32.1.1升降横移式..................................................32.1.2垂直循环式.................................................32.1.3巷道堆垛式.................................................42.1.4垂直升降式.................................................42.2设计中的立体车库类型的确定......................................53.提升机构方案的选择...............................................73.1对提升机构的分析................................................73.2具体设计方案及其选择............................................83.2.1驱动形式...................................................93.2.2平衡方式..................................................113.2.3安装方式..................................................114．箱体的设计计算..................................................124.1箱体的设计计算.................................................124.1.1箱体顶部及侧部结构设计.....................................12-2-4.1.2载车板的设计计算...........................................124.1.3箱体底部的结构设计计算....................................134.1.4箱底突台设计计算...........................................154.1.5箱底衬板设计计算...........................................164.2配重的设计计算.................................................175.标准部件的选择..................................................185.1对电动机的分析和选用...........................................185.1.1性能和分类................................................185.1.2选择电动机应综合考虑的问题................................195.1.3本提升机构电动机的类型选择................................205.1.4电动机具体型号的选择.......................................205.2对联轴器的分析和选用...........................................235.2.1主要性能和分类............................................235.2.2联轴器选择原则............................................235.2.3尺寸的选择................................................245.2.4本设计中联轴器的选择......................................245.3对制动器分析和选用.............................................275.3.1性能及分类.................................................275.3.2制动器的选择原则...........................................295.3.3本设计中制动器型号的选择..................................295.4对减速器的分析和选用...........................................31-3-5.4.1性能和分类................................................315.4.2选择减速器的原则..........................................325.4.3减速器类型的选择..........................................336.非标准件部件的设计和计算.........................................356.1钢丝绳及钢丝绳夹的选用.........................................356.2曳引轮的设计计算...............................................386.3顶轮的设计计算.................................................467.部件的设计和校核.................................................477.1长轴的设计计算及校核...........................................477.2短传动轴的设计计算.............................................527.3顶轴的设计计算.................................................538.轴承的选用与校核.................................................568.1轴承的选用.....................................................568.2对顶轴轴承寿命验算.............................................56总结.
