DT75-5绞车的设计毕业论文.doc

I摘要针对DT755绞车的具体的结构和工作时的具体要求,对其进行整体的设计。包括对电动机的选择,减速器的选用,卷筒的设计和校核以及主轴的设计和校核,其它一些零件的选用和设计和对绞车的各部位的润滑。在设计过程中查阅了相关的一些资料,发现现在所做的设计是一个传统的但又是非常有实际意义的设计。文中主要阐述了绞车的发展和具体对绞车的设计和部件的选用过程。主轴的设计主要针对其在绞车上受力,通过选择材料到初步确定尺寸,再进行受力分析,最后进行校核强度等一系列的步骤来设计出符合要求的轴。卷筒的设计主要通过设计的要求,对卷筒的材料,卷筒的直径,卷筒的壁厚等一系列问题进行综合的设计。并对设计的卷筒进行整体的强度校核。由于本人时间和知识面的有限,所以设计的绞车不可能很全面。文中错误难免,望老师给于指正。关键词绞车主轴卷筒减速器IIAbstractDT755winchforthespecificstructureandworkingatthespecificrequestofitsoveralldesign.Includingthemotorofchoice,thechoiceofreducer,reelinthedesignandverificationaswellasthemaindesignandverification,someotherpartsoftheselectionanddesignofthewinchandthevariouspartsoflubrication.Inthedesignprocessinspectionoftherelevantinformationandfoundthatthedesignisnowdonebyatraditionalbutaverymeaningfuldesign.Inthemaintextofawinchonthedevelopmentofthewinchandspecificpartsofthedesignandselectionprocess.Thedesignforthemainspindleinthewinchontheforce,throughthechoiceofmaterialstodeterminetheinitialsize,toconductAnalysis,afinalcheckoftheintensityandaseriesofstepsdesignedtomeettherequirementsoftheshaft.Reelmainlythroughthedesignofdesignrequirements,thereelofmaterial,thediameterreel,reelwallthicknessofaseriesofissuessuchasintegrateddesign.AndthedesignoftheoverallstrengthofReeltocheck.Becauseofmylimitedtimeandknowledge,sothedesignofthewinchisnotcomprehensive.Inthewronginevitably,tohopetheteacherscancorrected.KeywordsWinchSpindleReelReducer徐州工程学院毕业设计论文IV目录1绪论.............................................................................................................................................11.1课题背景................................................................................................................................11.1.1绞车的分类......................................................................................................................11.1.2绞车的特点和性能要求..................................................................................................11.2国内外绞车发展状况............................................................................................................21.2.1国内绞车发展现状..........................................................................................................21.2.2国外绞车发展现状..........................................................................................................32钢丝绳的选型..............................................................................................................................42.1机构工作类型选择................................................................................................................42.2钢丝绳选择计算....................................................................................................................42.3钢丝绳强度校校核................................................................................................................53卷筒的设计.................................................................................................................................63.1设计卷筒................................................................................................................................63.1.1卷筒的材料......................................................................................................................63.1.2卷筒容绳尺寸计算..........................................................................................................63.2卷筒强度分析.....................................................................................................................73.2.1卷筒的强度计算..............................................................................................................73.2.2稳定性验算......................................................................................................................83.3钢丝绳尾在卷筒上的固定计算............................................................................................83.2.3压板固定计算..................................................................................................................83.3.2压板类型选择................................................................................................................104传动机构设计............................................................................................................................114.1传动方案设计......................................................................................................................114.2电动机选型..........................................................................................................................114.2.1主要参数........................................................................................................................114.2.2选择电动机....................................................................................................................114.3减速器选型..........................................................................................................................134.3.1减速器的定义及作用....................................................................................................134.3.3减速器的选择.....................
