复摆颚式破碎机设计.doc

河南理工大学万方科技学院毕业设计（论文）PAGEVII摘要国内使用的鄂式破碎机类型很多,复摆鄂式破碎机结构简单，制造容易、工作可靠、使用维修方便，所以常见的还是传统的复摆鄂式破碎机。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。本毕业设计主要为满住生产需求，出料口尺寸：10-40mm；进料口尺寸：125mm；产量;2-3t/h而研究的。根据以上要求我设计了复摆鄂式破碎机（PE150×250），其工作原理是：工作时，电动机通过皮带轮带动偏心轴旋转，使动鄂周期地靠近、离开定鄂，从而对物料有挤压、搓、碾等多重破碎，使物料由大变小，逐渐下落，直至从排料口排出。设计内容主要包括了复摆鄂式破碎机的动鄂、偏心轴、皮带轮、动鄂齿板、机架等一些重要部件；另外对鄂式破碎机的工作原理及特点和主要部件作了介绍，包括保险装置、调整装置、机架结构、润滑装置等；同时对机器参数（主轴转速、生产能力、破碎力、功率等）作了计算。此外也简单介绍了破碎的意义、破碎工艺和破碎比的计算，鄂式破碎机的主要部件的安装、鄂式破碎机的操作及维修等。关键词：复摆鄂式破碎机；动鄂；偏心轴；优化设计Cad图纸加qq:780256221AbstractTherearemanytypeofjawcrusherusedinourcountry,Compoundpendulumjawcrusherstructureissimple,easytomanufacture,reliable,convenientuseofmaintenance,sojawcrusherisusedverycommon.Alongwiththemodernizeddevelopment,thedemandofvariousindustrysectorforthebrokencrushedstonefurtherincrease,sostudyingtheduplicatependulumJaw-fashionedCrusherhavetheveryvitalsignificance.Thisgraduationprojectmainlyisformeetstheproductionneed:Dischargeholesize:10∼40mm;Feedingblockgreatestsize:125mm;Output:2∼3t/h.AccordingtotheaboveacquirementhavedesignedCompoundpendulumjawcrusher(PE150×250).Itsprincipleofworkisthattheelectricmotorleadstherotationofeccentricaxisthroughthebeltpulley,whichcausesthemovingjawtoapproachandtoleavethesettingjawperiodically,thusitmakesthematerialtotheextrusion,torub,togrindandsoon.Multiplestave,whichcausesthematerialchangefrombigtosmall,untildischargefromthedumpmouth.Thecontentofthisdesigntotallyincludesjawcrusher’ssomeimportantcomponents，suchasmovejaw,eccentricshaft,beltpulley,toothedrackofmovejaw,rackandsoon;Inother,weintroducedtheprincipleofjawcrusher,Featuresofjawcrusherandimportantcomponents,includinginsuranceunit,adjustmentunit,rackstructure,lubricationunitandsoon.Atthesametime,wecomputedparameterofthemachine(thespeedofmainaxle,Productivity,thestrengthofstavepowerandsoon)anddesignedtheeccentricshaft.Furthermore,wesimplyintroducedthesignificanceofstave,stavetechnologyandthecomputationofstavestrength,Installationofthemaincomponentsinjawcrusher,theoperat
