文档介绍：摘要本次毕业设计是针对毕业实****中桥式起重机所做的具体到吨位级别的设计。我国现在应用的各大起重机还是仿造国外落后技术制造出来的,而且已经在工厂内应用了多年,有些甚至还是七八十年代的产品,无论在质量上还是在功能上都满足不了日益增长的工业需求。如何设计使其成本最低化,布置合理化,功能现代化是我们研究的课题。本次设计就是对小吨位的桥式起重机进行设计,主要设计内容是10t桥式起重机的结构及运行机构,其中包括桥架结构的布置计算及校核,主梁结构的计算及校核,端梁结构的计算及校核,主端梁连接以及大车运行机构零部件的选择及校核包括:轮压计算及强度验算,运行阻力计算,选择电动机,减速器的选择验算,运行速度及实际功率,选择制动器,选择联轴器,低速浮动轴的验算,缓冲器的选择等计算。还有小车的运行和起升机构零部件的选择及校核包括:运行阻力计算,选电动机,选择减速器验算起动时间,按起动工况校核减速器功率,选择制动器,选择高速轴联轴器及制动轮,验算低速浮动轴强度,钢丝绳的选择,滑轮、卷筒的计算,联轴器的选择。关键词:起重机;大车运行机构;小车运行结构;小车起升结构;桥架;主端梁AbstractThegraduationdesignisaimedatthegraduationfieldworkmedium-,someevenapplicationorthe70sand80sproducts,bothinqualityandinonthefunctioncan',decoraterationalization,,anization,includingbridgestructurearrangementcalculationandcheckingthestructureofthegirder,thecalculationandchecking,calculatedandcheckedthebeamstructure,themaingirdersconnectionandcartmechanismpartsselectionandcheckingincluding:wheelpressurecalculationandintensitychecking,runningfrictioncalculation,thechoiceofmotor,gearreducerischecked,choosespeedandactualpower,choosebrakes,choosecouplingcalculatingspeedfloatingaxis,bufferchoicecalculation,:runningfrictioncalculation,choosemotor,choosereducer,bystartingcheckedstart-uptimecheckreducerpower,chooseworkingbrakes,choosehigh-speedcouplingsandbrakewheel,thecheckinglow-speedaxialintensity,thewireropefloatingchoice,pulley,drumcalculation,:cranes;anization;Carrunningstructure;Carhoistingstructure;Bridge;
