PE400×600复摆颚式破碎机结构设计

洛阳理工学院毕业设计（论文）IPE400×600复摆颚式破碎机结构设计摘要国内使用的颚式破碎机类型很多，但最常见的还是传统的复摆颚式破碎机。复摆颚式破碎机的出现已有百余年的历史，经过长期的实践和改进，其结构和参数已趋于完善。由于其结构简单、制造容易、工作可靠以及维修方便等优点，在冶金、矿山、建材、化工等行业应用极为广泛。随着社会生产力的发展，各工矿行业对破碎机的性能有了进一步的要求，因此设计符合现代工业生产需要的复摆颚式破碎机具有很大的现实意义。本毕业设计主要是为满足现代工业生产要求而设计的中型复摆颚式破碎机，主要应用于中小企业的粉碎作业。其基本参数如下：进料口尺寸400×600（mm）；最大给矿粒度350（mm）；排矿口调整范围40~160（mm）；生产能力17~115（t/h）。本设计主要内容包括：破碎机工作原理的简要分析、各项工作参数的选择、关键零部件的结构设计。关键词：复摆颚式破碎机，工作原理，工作参数，结构设计洛阳理工学院毕业设计（论文）IIMachineStructureDesignOfPE400*600JawCrusherABSTRACTThedomesticuseofjawcrushertypemany,butthemostcommonisthetraditionalsingletogglejawcrusher.Singletogglejawcrusherhasbeenoverahundredyearsofhistory,throughlong-termpracticeandimprovement,itsstructureandparametershastendedtoimprove.Becauseofitssimplestructure,easymanufacture,reliableworkandconvenientmaintenance,etc.,itiswidelyusedinmetallurgy,mine,buildingmaterials,chemicalindustryandsoon.Withthedevelopmentofsocialproductiveforces,theminingindustryofcrushingmachineperformancewithfurtherrequirements,sothedesignmeettheneedsofmodernindustrialproductionofcompoundpendulumjawcrusherisofgreatpracticalsignificance.Thisgraduationdesignismainlydesignedtomeettherequirementsofmodernindustrialproductionmediumcompoundpendulumjawcrusher,thebasicparametersareasfollows:intothedischargeholesize400x600(mm);maximumtotheoreparticlesize(350mm);roworemouthadjustmentrange40-160(mm);productioncapacity17~115(mm).Themaincontentsofthisdesigninclude:theanalysisoftheworkingprincipleofthecrusher,thechoiceoftheworkingparameters,thestructuredesignofthekeypartsKEYWORDS:CompoundPendulumJawCrusher，WorkingPrinciple，WorkingParameters，StructureDesign洛阳理工学院毕业设计（论文）III目录前言................................................................................................1第1章复摆颚式破碎机的简介.......................................................31.1复摆颚式破碎机应用范围...................................................31.2复摆颚式破碎机工作原理...................................................41.3PE400×600复摆颚式破碎机工作原理...............................5第2章PE400×600复摆颚式破碎机参数的选择和计算...............72.1结构参数的选择与计算........................................................72.1.1给矿口与排矿口的尺寸..............................................72.1.2钳角α的选取.............................................................72.1.3动鄂摆动行程s的选取...............................................72.1.4偏心轴的偏心距r的选取...........................................82.1.5破碎腔高度H的选取..................................................82.1.6轴承中心距给矿口的高度h的确定............................82.1.7偏心距r对连杆长度l的比值λ..................................82.1.8肘板长度K的选取......................................................92.1.9破碎腔形状的确定.....................................................92.2工作参数的选择与计算.....................................................102.2.1偏心轴转速n的计算.................................................102.2.2生产率Q的计算........................................................112.2.3功率N的计算...........................................................122.2.4电动机的选择...........................................................122.3破碎机各项参数列表.........................................................12第3章PE400×600复摆颚式破碎机关键零件的设计.................143.1V带传动部分的设计计算...................................................143.1.1确定计算功率cP........................................................143.1.2确定V带的带型......................................................143.1.3确定带轮的基准直径...............................................143.1.4确定中心距a和V带长度dL....................................14洛阳理工学院毕业设计（论文）IV3.1.5校核小带轮包角1....................................................153.1.6确定V带根数..........................................................153.1.7计算单根V带初拉力0F...........................................163.1.8计算对轴的压力Q....................................................163.1.8V带传动的主要参数归纳.........................................163.2飞轮的设计.........................................................................163.3推力板的设计.....................................................................173.4偏心轴的设计.....................................................................183.4.1偏心轴的材料选择和最小直径估算........................183.4.2偏心轴结构的设计...................................................183.4.3偏心轴强度校核.......................................................193.5轴承的选择.........................................................................203.6动颚的设计.........................................................................213.7齿板的设计.........................................................................213.8肘板的设计.........................................................................223.9调整装置的设计.................................................................233.10保险装置的设计...............................................................243.11机架结构的设计...............................................................243.12破碎机的润滑装置...........................................................25结论..............................................................................................26谢辞.......................................................
