JM型建筑卷扬机设计毕业论文.doc

I摘要虽如今工业水平先进,机械化程度不断提高,起重设备不断更新,但仍不能淘汰卷扬机这行之有效的机械设备。本人所研究的是JM建筑卷扬机。JM系列属慢速卷扬机。在本设计中主要对卷扬机传动部分、工作机构及卷扬机的主体部分进行设计。在传动部分采用的是二级齿轮减速器和开式齿轮传动,工作部分的卷筒采用的是焊接式卷筒。该卷扬机的主要特点是结构简单,操作方便。此机器的主要功能在建筑业的冷拉钢筋提升重物,在林业的集材工作,同时在水电、农业等行业均能被采用。该类机器的发展趋势应该向大型化、采用先进电子控制、手提式卷扬机、不带电源装置的卷扬机的方向发展。关键词卷扬机设计发展功能IIAbstractAlthoughthelevelofadvancedindustrialToday,theincreasinglymechanized,liftingequipmentconstantlyupdated,butstillcannothoistitoutofeffectivemachineryandequipment.IstudiedthebuildingisJMwinch.JMseriesisaslowhoist.Duringthedesignofthemainpartofthehoistdrive,workandthewinchthemainpartofthedesign.Inpartusingatransmissiongearreducerandtwoopengeartransmission,theworkingpartofthereelisusedinweldingreel.Themaincharacteristicsofthehoiststructureissimple,easytooperate.Theprimaryfunctionofthismachinetheconstructionindustryinthecolddrawnsteelweightsincrease,theskiddinginforestrywork,whileinthewaterandelectricity,agricultureandotherindustriescanbeused.Thedevelopmenttrendofsuchmachinestobelarge,theuseofadvancedelectroniccontrol,portablewinch,nonpowerdevicesinthedirectionofthewinch.KeywordswinchdesigndevelopmentfunctionIII目录1绪论.............................................................................................................................................11.1建筑卷扬机的发展状况.......................................................................................................11.1.1建筑卷扬机的应用........................................................................................................11.1.2建筑卷扬机的发展概况................................................................................................11.1.3国外卷扬机的概况........................................................................................................11.2建筑卷扬机的主要类型.......................................................................................................21.2.1按钢丝绳额定拉力F分...............................................................................................21.2.2按钢丝绳额定速度v分.................................................................................................21.2.3按卷筒数目分................................................................................................................31.2.4按动力源分....................................................................................................................31.2.5按传动形式分................................................................................................................31.2.6按控制方法分................................................................................................................31.2.7按用途分........................................................................................................................31.3建筑卷扬机的计算基础.......................................................................................................41.3.1建筑卷扬机工作级别与类别........................................................................................41.3.2利用等级........................................................................................................................41.3.3建筑卷扬机分类............................................................................................................42卷扬机的基本结构设计..............................................................................................................62.1电控卷扬机...........................................................................................................................62.2溜放型建筑卷扬机...............................................................................................................62.3本设计的总体确定...............................................................................................................72.4卷扬机的总体结构设计.......................................................................................................73钢丝绳的选择和卷筒的设计......................................................................................................83.1钢丝绳的选择.......................................................................................................................83.1.1钢丝绳的种类和构造....................................................................................................83.1.2钢丝绳直径的选择........................................................................................................83.2卷筒的设计...........................................................................................................................83.2.1卷筒的材料....................................................................................................................93.2.2卷筒容绳尺寸计算........................................................................................................93.2.3卷筒筒壁的厚度计算和卷筒壁的强度计算..............................................................103.3卷筒轴的设计.....................................................................................................................114减速器和开式齿轮的设计.......................................................................................................154.1电动机的选择........................
