5吨电动卷扬机的设计2008.4摘要随着社会的发展,机械将会越来越取代人力,这也是机械行业飞速发展的后果,在机械的发展历史中,新机械的发明有着举足轻重的作用。但是,那些很久以前就被利用生产并一直延续到今天的机械,更是起着不可替代的作用,卷扬机就是一例。卷扬机的发展就像其他机械一样,从开始的简单到现在的复杂,从以前的机械动力到现在的电力动力,从以前的人工操作到现在的电脑操作甚至智能操作。本设计就传统的卷扬机说起,一直到现在以及将来的发展。本设计主要设计了5吨卷扬机的卷筒、卷筒轴、卷筒毂、减速器以及滑轮组。其中卷筒和卷筒轴的设计最为主要,本设计重点做了介绍。其余部分由于篇幅有限,只是略作分析。关键词卷扬机卷筒卷筒轴滑轮组5吨电动卷扬机的设计2008.4AbstractAlongwithsocietysdevelopment,themachinerywillbeablemoreandmoretosubstituteforthemanpower,thisalsowillbethemechanicalprofessionrapiddevelopmentconsequence,inthemachinerysubstitutionmanpowerdevelopmenthistory,thenewmachineryinventionhasthepivotalfunction.But,theseveryforalongtimeonandcontinuecontinuouslyusingtheproductiontotodaymachinery,isplayingtherolewhichcannotbesubstituted,thehoistisanexample.Thehoistdevelopmentislikelysameonothermachineries,fromstartssimplyuntilpresentcomplex,frombeforehandmanpowertopresentelectricpower,frombeforehandmanualcontroltopresentcomputeroperationevenintelligenceoperation.Thisdesignmentionsonthetraditionalhoist,continuouslytopresentaswellasfuturedevelopment.Thedesigninstructionbooklethasmainlydesigned5tonhoistreels,thereelaxis,aswellastheblockandtackle.Reelaswellasthereelaxisdesignismostmain,thisdesignhasmadetheintroductionwithemphasis.Becauseotherpartsthelengthislimited,onlymakestheanalysisslightly.KeywordsWindlassReelReelaxisBlockandtackle5吨电动卷扬机的设计2008.4目录摘要.......................................................................................................................................ⅠAbstract.....................................................................................................................................Ⅱ第一章概论...............................................................................................................................11.1卷扬机发展概况............................................................................................................11.1.1卷扬机的应用..................................................................................................11.1.2卷扬机的发展概况..........................................................................................11.1.3国外卷扬机概况..............................................................................................31.1.4卷扬机的发展趋势.........................................................................................51.2卷扬机主要类型............................................................................................................51.3电动卷扬机基本结构...................................................................................................71.3.1电控卷扬机......................................................................................................71.3.2带有电磁铁制动器的卷扬机..........................................................................81.3.3采用锥形转子电动机的卷扬机......................................................................91.3.4溜放型卷扬机................................................................................................10第二章起升机构的组成及型式.............................................................................................102.1起升机构的组成..........................................................................................................102.2起升机构的典型传动型式..........................................................................................12第三章钢丝绳的选择.............................................................................................................143.1钢丝绳的种类和构造..................................................................................................143.2钢丝绳直径的选择......................................................................................................153.3钢丝绳的使用..............................................................................................................17第四章卷筒的结构设计及尺寸确定.....................................................................................184.1卷筒的分类..................................................................................................................184.2卷筒绳槽的确定..........................................................................................................195吨电动卷扬机的设计2008.44.3卷筒的设计..................................................................................................................204.3.1卷筒节径D0的设计................................................................................................204.3.2卷筒长度的计算.......................................................................................................214.3.3卷筒壁厚的计算.......................................................................................................224.4卷筒强度的计算..........................................................................................................23第五章卷筒轴的设计计算.....................................................................................................245.1卷筒轴的受力分析与工作应力分析..........................................................................245.2卷筒轴的设计计算......................................................................................................25
