复摆颚式破碎机(800×1060)设计

河北建筑工程学院本科毕业设计（论文）题目复摆颚式破碎机（800×1060）设计学科专业机械设计制造及其自动化班级机101姓名指导教师肖溪马轶群摘要目前国内使用的破碎机类型很多，主要有鄂式破碎机、锤式破碎机、圆锥破碎机、反击式破碎机和辊式破碎机。复摆式颚式破碎机与简摆式相比较，其优点是：质量较轻，构件较少，结构更紧凑，破碎腔内充满程度较好，所装物料块受到均匀破碎，加以动颚下端强制性推出成品卸料，故生产率较高，比同规格的简摆颚式破碎机的生产率高出20-30%；物料块在动颚下部有较大的上下翻滚运动，容易呈立方体的形状卸出，减少了像简摆式产品中那样的片状成分，产品质量较好。本设计需求参数为进料口尺寸：800×1060mm；最大进料粒度：640mm；处理能力：85～143m³/h；偏心轴转速：250r/min；排料口调整范围：100～200mm；电动机功率：90KW。设计分析了破碎机的发展现状和研究颚式破碎机的意义及复摆颚式破碎机机构尺寸对破碎性能的影响，计算确定了PE800×1060的机构参数，设计内容主要包括复摆颚式破碎机的动颚、偏心轴、皮带轮、动颚齿板、定颚齿板、机架等一些重要部件；另外，对颚式破碎机的工作原理及特点和主要部件的作用作了介绍，包括保险装置、调整装置、机架结构、润滑装置等；同时对机器的参数（主轴转速、生产能力、破碎力、功率等）作了计算。此外，对破碎的意义、破碎工艺和破碎比的计算，颚式破碎机的主要部件的安装、操作及维修作了简单介绍。关键词：复摆颚式破碎机带传动飞轮磨损ABSTRACTCurrently，thetypeofthecrusherismultitudinousindomestic,mainlyincludingjawcrusher,hammercrusher,conecrusher,impactbreakerandrollcrusher.Comparedwithfineimpactcrusher，SBM（swingingjawbreakmachine）´sadvantageis:qualityislighter,lesscompactstructurecomponent,brokenlumenfilledwithdegreeisgood,withmaterialsbyuniformbroken,toblockbottommandatorymovejawisunloading,launchfinishedhigher,thanwithspecificationsproductivityoffineimpactcrusher20-30%higherthantheproductivity;Materialblocksinthelowerhavebiggerjawsmoveupanddownmovement,acubetumblingtotheshapeof,reducingthedischargedasJanetiltingproductsthatflakecomposition,productqualityisbetter.Thisdesignisdonefor：thefeedingportsizeis800x1060mm;Maximumfeedinggranularityis640mm;Productionefficiencyis85-143m³/h;Eccentricshaftspeedis250r/min;Dischargingmouthadjustmentrange100mmto200mm;Motorpoweris90KW.Thisdesignanalysisofthecurrentdevelopmentofthecrushier,themeaningsofresearchingthecrusher,howthedimensionsofjawcrushereffectontheperformanceofthebroken,calculateanddeterminethePE800x1060structureparameters,thedesigncontentmainlyincludesswingjaw,eccentricshaft,pulley,seingjawgearplate,andsettledjawgearplateandframeandsomeotherimportantcomponents;Inaddition,jawcrusherprincipleandcharacteristicsandmaincomponentfunctionisintroduced,includinginsurancedevice,adjustingdevicesandframestructure,lubricationdevice,etc.;Alsoonthemachineparameters(spindlespeed,productioncapacity,crushingstrength,power)calculateaswell.Inaddition,thesignificanceofbroken,crushingprocessandcalculationofcrushingratio,jawcrushermaincomponentinstallation,operationandmaintenanceareintroduced.KEYWORDS：JawcrusherBeltdriveFlywheelWear目录第1章绪论··················································································11.1引言·························································································11.2复摆颚式破碎机的特点··································································31.3国内外颚式破碎机的发展及现状·························································5第2章总体设计············································································82.1复摆鄂式破碎机的基本结构·····························································82.2复摆鄂式破碎机的工作原理·····························································10第3章主要参数的确定··································································123.1已知参数··················································································123.2部分结构参数的确定·····································································123.3动鄂的摆动次数···········································································143.4电动机的选择·············································································153.5四连杆机构各杆长度的确定·····························································163.6最大破碎力················································································173.7各部件受力分析···········································································17第4章传动装置的设计··································································204.1带轮的设计················································································204.2偏心轴的设计·············································································254.3飞轮的设计················································································274.4轴承的选择与校核········································································294.5轴承座的设计·············································································314.6配重的选择················································································324.7外形尺寸的设计···········································································33第5章各基本构件的设计······························································355.1动鄂的设计···············································································355.2齿板的设计················································································385.3推力板的设计·············································································405.4调整装置的设计···········································································415.5破碎腔型的形状···········································································435.6机架的设计···············································································44第6章复摆鄂式破碎机的安装························································476.1破碎机的安装·····················································
