复摆鄂式破碎机设计及计算毕业论文.doc

I摘要国内使用的鄂式破碎机类型很多,但常见的还是传统的复摆鄂式破碎机。复摆鄂式破碎机的出现已有140多年的历史,经过人们长期的实践和不断完善与改进,其结构型式和机构参数日臻合理,结构简单、制造容易、工作可靠、维修方便,故在冶金、矿山、建材、化工、煤炭等行业使用非常广泛。随着现代化的发展,各工业部门对破碎石的需求进一步增长,研究复摆鄂式破碎机具有很重要的意义。本毕业设计主要是为满足生产需求进料口尺寸9001200(mm)出料口尺寸mm200100进料块最大尺寸mm750产量时吨/300150而研究的。主要研究复摆鄂式破碎机的运动分析、主要零件受力校核、鄂板、齿板磨损的分析,各种工作参数的选择,工作机构的优化。重点研究传动的设计和系统的优化。关键词复摆鄂式破碎机传动磨损IIABSTRACTThedomesticusejawtypebreakertypeareverymany,ButcommontraditionalduplicatependulumJawfashionedCrushe.Theduplicatependulumjawtypebreakerappearancehadmorethan140yearshistory,Andconsummatesandtheimprovementunceasinglyafterthepeoplelongtermpractice,Itsstructurepatternandtheorganizationparameteraredaybydayreasonable,Thestructuresimple,themanufactureiseasy,theworkreliably,theserviceconvenient,thereforeinprofessionuseandsoonthemetallurgy,mine,buildingmaterials,chemicalindustry,coalisextremelywidespread.Alongwiththemodernizeddevelopment,variousindustrysectorfurthergrowstothebrokencrushedstonedemand,studiestheduplicatependulumJawfashionedCrushetohavetheveryvitalsignificance.ThisgraduationprojectmainlyisformeetstheproductionneedFeedheadsize9001200(mm)Dischargeholesizemm200100Feedingblockgreatestsizemm750Outputht/300150.MainlystudiestheduplicatependulumJawfashionedCrushethemovementanalysis,Vbeltchoice,theanalysiswhichtheJawfashionedCrushe,thetoothedrackwears,eachkindofoperationalparameterchoice,operatingmechanismoptimization.Keyresearchtransmissiondesignandsystemoptimization.KeywordsJawfashionedCrusheTransmissionAbrasionIII1目录1绪论...................................................................................................................................11.1破碎机概述.................................................................................................................11.2破碎粒度.....................................................................................................................11.3选题背景.....................................................................................................................21.3.1设计条件...............................................................................................................21.3.2设计内容...............................................................................................................21.3.3设计关键...............................................................................................................31.3.4设计要求...............................................................................................................32物料破碎及其意义............................................................................................................42.1物料破碎及其意义.....................................................................................................42.1.1破碎的目的...........................................................................................................42.1.2破碎工艺...............................................................................................................42.2破碎物料的性能及破碎比.........................................................................................62.2.1粒度及其表示方法...............................................................................................62.2.2破碎产品的粒级特性...........................................................................................72.2.3矿石的破碎及力学性能........................................................................................93.工作原理和构造............................................................................................................123.1工作原理....................................................................................................................123.2鄂式破碎机的结构....................................................................................................134.1连杆.............................................................................................................................154.2动鄂.............................................................................................................................164.3齿板的结构.................................................................................................................164.4肘板.............................................................................................................................174.5调整装置.....................................................................................................................184.6保险装置.....................................................................................................................194.7机架结构.....................................................................................................................194.8传动件.........................................................................................................................204.9飞轮.............................................................................................................................214.10润滑装置..........................................................................................................
