鄂式破碎机毕业设计说明书摘要修改版

摘要I摘要从破碎机的现状来看，国内产品的机重高于国外，而且颚式破碎机的设计目前仍偏重于经验方法。随着计算方法与计算机技术的发展，在满足强度、刚度以及安全性能的前提下，对动颚结构设计进行优化，以减轻机重是一个可行的解决方案。从动颚水平位移的仿真结果可以看出动颚的水平行程较大，这样有利于破碎物料。沿动颚运动轨迹的运动方向有促进排料作用，所以在一定的程度上可以保证破碎机的生产效率。从动颚竖直位移仿真结果中也可以看出垂直的行程较大，从而导致衬板磨损较快，降低衬板的使用寿命，故复摆颚式破碎机一般用于中小型机型。但随着耐磨材料的不断发展，衬板耐磨性的提高，这种机型也逐渐向大型化方向发展。我的设计中主要研究复摆颚式破碎机的运动分析、V带的选择，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AbstractIIAbstractThedomesticusejawtypebreakertypeareverymany,ButcommontraditionalduplicatependulumJaw-fashionedCrusher.Theduplicatependulumjawtypebreakerappearancehadmorethan140yearshistory,Andconsummatesandtheimprovementunceasinglyafterthepeoplelong-termpractice,Itsstructurepatternandtheorganizationparameteraredaybydayreasonable,Thestructuresimple,themanufactureiseasy,theworkreliably,theserviceconvenient,thereforeinprofessionuseandsoonthemetallurgy,mine,buildingmaterials,chemicalindustry,coalisextremelywidespread.Alongwiththemodernizeddevelopment,variousindustrysectorfurthergrowstothebrokencrushedstonedemand,studiestheduplicatependulumJaw-fashionedCrushertohavetheveryvitalsignificance.Thisgraduationprojectmainlyisformeetstheproductionneed:Feedheadsize:mm1200900;Dischargeholesize:mm200~100;Feedingblockgreatestsize:mm750;Output:ht/300~150.MainlystudiestheduplicatependulumJaw-fashionedCrusherthemovementanalysis,Vbeltchoice,theanalysiswhichtheJaw-fashionedCrusher,thetoothedrackwears,eachkindofoperationalparameterchoice,operatingmechanismoptimization.Keyresearchtransmissiondesignandsystemoptimization.KeyWords：Jaw-fashionedCrusherTransmissionAbrasion目录III目录摘要........................................................................................................................IAbstract..........................................................................................................................II1绪论...........................................................................................................................11.1研究的目的和意义..........................................................................................11.2特点和现状与发展..........................................................................................31.2.1复摆鄂式破碎机的特点........................................................................31.2.2复摆鄂式破碎机的现状与发展...........................................................51.3国内外复摆鄂式破碎机的进展......................................................................82总体设计过程.........................................................................................................102.1基本结构和工作原理....................................................................................102.1.1基本结构：..........................................................................................102.1.2工作原理..............................................................................................102.2主要参数........................................................................................................122.2.1钳角..................................................................................................122.2.2动颚水平行程YS................................................................................132.2.3传动角...............................................................................................132.2.4偏心距E...............................................................................................132.3电动机的选择................................................................................................132.4电动机的容量................................................................................................142.5选择电动机的型号........................................................................................142.6V带的传动....................................................................................................152.7技术性能参数................................................................................................182.8复摆颚式破碎机的动鄂的工作过程分析....................................................182.9偏心轴的改进................................................................................................192.9.1改进前状况..........................................................................................202.9.2修复及改进措施..................................................................................212.9.3改进效果..............................................................................................22目录IV3磨损.......................................................................................................................233.1复摆鄂式破碎机齿板磨损的分析................................................................233.2颚板磨损机制...............................................................................................253.3对鄂板材质的选择........................................................................................264部分零件上的公差和配合...................................................................................274.1配合的选择....................................................................................................274.1.1配合的类别的选择...
