250x400颚式破碎机设计说明书.

1摘要国内使用的颚式破碎机类型很多,复摆颚式破碎基结构简单，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颚式破碎机。本毕业设计主要是为满足生产需求出料口尺寸：50~60mm；进料块最大尺寸：200mm；产量：50~20吨而研究的。根据以上要求我设计了复摆颚式破碎机（PE250X400）。设计分析了颚式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PE250X400的设计参数。设计内容主要包括了复摆颚式破碎机的动颚、偏心轴、皮带轮、地基、动颚齿板、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）作了计算以及对偏心轴作了设计。此外也简单介绍了破碎的意义、破碎工艺和破碎比的计算，颚式破碎机的主要部件的安装、颚式破碎机的操作及维修等。关键词：复摆颚式破碎机传动磨损2ABSTRACTStatisticsindicatedthatthematerialsprocessing’Sfirstworkingprocedur——_crushingjobconsumestheelectricitytooccupyaboveoredressingplanttotalpowerconsumption50％．SimultaneouslyusesaPE250x400jawcrusherjawplate(fixedjawplateandmovesjawplateeachtogether)，thegrossweight0．2ton，accordingtothenationaljawcrusherleaststandardcapacity70，000computation，everyyearthenationmustconsumethehighmanganesesteel56，000tonsapproximately．Thisincludesthematerialcrushingcostdirectly,jawplate’Slossintobesidesjawcrusherenergyconsumptionanotherbigloss．Thereforethejawcrusher'senergyconsumptionandthejawplatedesignparameteraretheimportantquestionswhichthejawcrushermanufacturerandtheusercared，thereforethisarticlemainlyrevolvestoreducethejawcrusherenergyconsumptionandtheextensionjawplateservicelifetopicconductstheresearch．Paperprimetaskandinnovationasfollows：1．Usingthediffusionstructuraltheoryandthedamagemechanicstheory,theunionstrainequivalentassuming，infersinthematerialscrushingprocessthedamageenergyliberationrateandbetweenthedamagevariablerelationship，basedonthisandobtainsinthematerialscrushingprocessdamageenergyliberationratecriticalthresholdvalue；2．Takethejawcrusher’Sdesignparameterasthefoundation，theunionmaterialinjawcrusherdistributedcharacteristic，infersthejawcrusherelectricalmachinerypowermathematicalmodel，utilizesthismodeltocalculatethreekindofmodeljawcrusherelectricalmachinerypower,andthroughthreekindofmodeljawcrushercrushingsandstone’Selectricalmachinerypowertestexperiment，hasconfirmedtheinferentialreasoningmathematicalmodelrationality；．3．UtilizedthefuzzystochastictheorytocarryontheanalysistothePE250×400jaw3platestresssituation，hascarriedonthecomputationusingtheAnsyssol,waretothejawplatestress，andmadetheimprovementtothejawplatedesignparameter,aftertheimprovementKeyword;JawCrashertransmissionabrasion1本资料来自举哥设计工作室，此文档为说明书的部分内容，如需要本资料的全部内容请淘宝网搜索店铺举哥设计工作室，在店铺内搜索颚式破碎机等关键词以下为全部文件列表的截图，包含图纸和说明书2目录前言........................................................11选题背景...................................................31.1发展现状与意义概述..................................31.2颚式破碎机的特点....................................41.3颚式破碎机的分类......................................61.4破碎的目的...........................................81.5破碎工艺.............................................81.6破碎物料的性能及破碎比..............................101.6.1粒度及其表示方法...............................101.6.2破碎产品的粒级特性.............................111.6.3矿石的破碎及力学性能...........................121.6.4破碎机的破碎比.................................142复摆颚式破碎机的工作原理及结构............................152.1复摆颚式破碎机的工作原理.............................152.2复摆颚式破碎机的结构................................163主要零部件的结构分析......................................183.1动颚................................................183.1.1动颚的结构.....................................183.1.2动颚工作过程分析...............................193.2齿板................................................213.3肘板（推力板）......................................223.4电动机的选择........................................233.5v带的传动设计......................................243.6飞轮的设计.........................................2733.7偏心轴的设计........................................283.7.1偏心轴主要尺寸的确定...........................283.7.2偏心轴细部结构.................................293.7.3偏心轴的校核...................................303.8轴承的选择.........................................323.9推力板的设计.......................................324复摆式颚式破碎机主要参数的设计计算........................344.1主要参数的设定.....................................344.1.1已知条件......................................344.1.2传动角........................................344.1.3动颚水平行程和偏心轴的偏心距..................354.1.4主要构件尺寸的确定............................364.1.5破碎腔的形状...................错误!未定义书签。4.2机器参数............................错误!未定义书签。4.2.1主轴转速.......................错误!未定义书签。4.2.2生产能力......................错误!未定义书签。4.2.3破碎力.........................错误!未定义书签。4.3功率...............................错误!未定义书签。4.4各个部件的受力分析..................错误!未定义书签。5复摆式颚式破碎机的安装....................错误!未定义书签。5.1破碎机的安装........................错误!未定义书签。5.2机架的安装..........................错误!未定义书签。5.3偏心轴和轴承的安装..................错误!未定义书签。5.4肘板的安装..........................错误!未定义书签。5.5动颚的安装..........................错误!未定义书签。5.6齿板的安装..........................错误!未定义书签。6颚式破碎机的磨损..........................错误!未定义书签。6.1齿板磨损分析.......................错误!未定义书签。6.2颚板磨损机制........................错误!未定义书签。6.3对颚板材质的选择....................错误!未定义书签。7颚式破碎机的使用.........................错误!未定义书签。7.1颚式破碎机出口扬尘的解决............错误!未定义书签。7.2颚式破碎机的操作...................错误!未定义书签。7.2.1启动前的准备工作..............错误!未定义书签。7.2.2．操作顺序
