PAGEIIPAGEI摘要本设计主要介绍了液压卷扬机的结构、总体设计及工作情况。其中对液压卷扬机传动系统的设计做了分析和理论推导，为开发同类产品提供了设计方法。卷扬机是钻探施工中升降钻具、套管及处理孔内事故的主要设备之一。液压卷扬机结构紧凑，传动平稳，调整范围大，操纵简单，易于安装。它即可与钻机配套，又可独立使用，是一个很值得开发的产品。随着我国各项事业的迅猛发展，对相关设备的安全性、方便灵活性和工作效率提出了更高的要求。为满足现在施工升降机的需要及冶金、矿山、轻工等行业起重设备更新之需，设计制造自由落钩卷扬机是事在必行的。本卷扬机采用三级行星齿轮传动，行星齿轮传动体积小，能够满足卷扬机的结构要求，同时行星齿轮传动效率高，承载能力大，工作平稳，用三级行星齿轮传动增大了转动比，从而达到了设计要求。关键词：自由落钩卷扬机；卷筒；传动比；行星齿轮；效率ABSTRACTThepaperintroducesthestructure，designandworkingconditionofahydraulichoister.Makeanalysisandtheoreticalguideforthehydraulichoisterwhichprovidesdesignmethodsforthedevelopmentofsimilarproducts.Hoisterisoneofthemainequipmentindrillingconstructiontripping，casingandhandlingaccidentsinthehole.Hydraulichoisterhasthecompactstructure，smoothtransmission，largeadjustmentrange，manipulatingsimpleandeasytoinstall.Itcanbeusedindependently，andisaveryworthwhileproducttodevelopment.Withtherapiddevelopmentofmanykindsofenterpriseinourcountry，manyrequestsaresetforthesecurity，theconvenienceflexibilityandtheworkingefficiencyofthecorrelationequipment.Tomeettheneedsofmodernconstructionandtheupdatingofmetallurgy，mining，lightindustryandothersectorsliftingequipment，designthefreedomhook-droppinghoisterisgoingnecessarily.Thehoisterusedthreeplanetarygearfordriving，thedrivingvolumeofplanetarygearissmall，whichcanmeetthestructuralrequirementsofhoister.Meanwhileplanetarygearhashighdrivingefficiency，bearingcapabilityisgreat，smooth，threelevelplanetarygearisusedtoincreasethetransmissionratio，soastoachievethedesignrequirements.Keywords:TheFreedomHook-droppingHoister;Drum;VelocityRatio;PlanetGear;Efficiency目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc170830778"摘要PAGEREF_Toc170830778\hIHYPERLINK\l"_Toc170830779"AbstractPAGEREF_Toc170830779\hIIHYPERLINK\l"_Toc170830780"第1章绪论PAGEREF_Toc170830780\h1HYPERLINK\l"_Toc170830781"1.1选题的背景和目的PAGEREF_Toc170830781\h1HYPERLINK\l"_Toc170830782"1.2国内外研究状况和相关领域中已有的研究成果PAGEREF_Toc170830782\h1HYPERLINK\l"_To
