100/25tA7通用桥式起重机设计（L=19m）I摘要起重机的出现大大提高了人们的劳动效率，以前需要许多人花长时间才能搬动的大型物件现在用起重机就能轻易达到效果，尤其是在小范围的搬动过程中起重机的作用是相当明显的。在工厂的厂房内搬运大型零件或重型装置桥式起重是不可获缺的。桥式起重机小车主要包括起升机构、小车架、小车运行机构、吊具等部分。其中的小车运行机构主要由减速器、主动轮组、从动轮组、传动轴和一些连接件组成。此次设计的桥式起重机是水电站桥式起重机，安装于丰满水电站扩建工程厂房内，用于水轮发电机组及其附属设备的安装和检修工作。水电站内设备一般都是大中型设备，对桥式起重机的载荷要求较高，所以对减速器性能要求较高。关键词：桥式起重机；小车运行机构；减速器100/25tA7通用桥式起重机设计（L=19m）IIDesignofthebridgetypehoistcraneCarmovementorganizationABSTRACTTheinventionofcranehasgreatlyincreasedpeople’sworkefficiency.Peoplecanusecranetohandlewithhugearticles,whichusedtobetakenalongtimetodo,especiallyinasmallarea.Thebridgetypehoistcraneisrequiredtohandlewithhugeaccessoryorhugedevice.Thebridgetypehoistcranecarconsistsofpromotedorganization,thecarframe，thecarmovementorganization,hoistingmechanismsandsoon.Itsoperationstructureiscomposedofreducer,thedrivingwheelgroup,thedrivenwheelgroup,thetransmissionshaftandsomeconnectfitting.Thecoreofthisstructureisthedesignofthereducer.Thisbridgetypehoistcraneisbeusedtothehydroelectricpowerstation.ItisinstalledintheexpandedworkshopofFengmanwaterandelectricitystation.Itisusedtoinstalling,examiningandrepairingthewater-turbinegeneratorsetanditsaccessorialequipments.theequipmentsinthewaterandelectricitystationarelargeormedium-size.Theseequipmentshaveahighrequestontheloadofbridgetypehoistcrane,sotheyalsohaveahighrequestonthecapabilityofthereducer.Keywords:bridgetypehoist,thereducer100/25tA7通用桥式起重机设计（L=19m）III摘要.............................................................................................................................IABSTRACT..................................................................................................................II1起重机小车设计........................................................................................................11.1小车主起升机构计算......................................................................................11.1.1确定起升机构传动方案，选择滑轮组和吊钩组................................11.1.2选择钢丝绳............................................................................................11.1.3确定滑轮主要尺寸................................................................................21.1.4确定卷筒尺寸，并验算强度................................................................21.1.5选电动机................................................................................................41.1.6验算电动机发热条件............................................................................51.1.7选择减速器............................................................................................51.1.8验算起升速度和实际所需功率............................................................51.1.9校核减速器输出轴强度........................................................................61.1.10选择制动器..........................................................................................71.1.11选择联轴器..........................................................................................71.1.12验算启动时间......................................................................................81.1.13验算制动时间......................................................................................81.1.14高速浮动轴..........................................................................................91.2.1确定起升机构传动方案，选择滑轮组和吊钩组..............................111.2.2选择钢丝绳..........................................................................................111.2.4确定卷筒尺寸，并验算强度..............................................................121.2.5选电动机..............................................................................................141.2.6验算电动机发热条件..........................................................................141.2.7选择减速器..........................................................................................141.2.8校核减速器输出轴强度......................................................................151.2.9选择制动器..........................................................................................161.2.10选择联轴器........................................................................................161.2.11验算起动时间....................................................................................171.2.12验算制动时间....................................................................................171.2.13高速浮动轴........................................................................................171.3.1确定小车传动方案..............................................................................201.3.2选择车轮及轨道并验算其强度..........................................................20100/25tA7通用桥式起重机设计（L=19m）IV1.3.3运行阻力的计算..................................................................................211.3.4选电动机..............................................................................................221.3.5验算电动机发热条件..........................................................................221.3.6选择减速器..........................................................................................231.3.7验算运行速度和实际所需功率..........................................................231.3.8验算起动时间.......
