提升机盘闸液压制动器设计论文

I题目：提升机盘闸液压制动器设计专业:机械设计制造及其自动化学生：杨庭杰（签名）：指导老师：周新建（签名）：摘要提升机在煤矿中是很关键的运输设备，在矿井的生产中占有很重要的地位，本次设计对于JK型、2JK-3/11.5提升机，将其制动系统中的盘闸制动器进行设计、计算及分析。首先对制动器的方案进行分析，选定最优方案，其次对于制动器的材料，摩擦片材料进行选择，再次，对制动器各部分零件图进行设计、计算、校核。至今为止矿井提升机用的制动器大部分是液压盘闸制动器，对其工作可靠性的分析及监测，具有很重要的意义。液压盘闸制动器作为一种很传统的制动器来说，它具有制动力矩易调整、结构简单、紧凑，通用性好、安全可靠性好等优点，对提升机、矿用提升设备安全有重要意义。关键词：制动系统；盘闸制动器；可靠性IISubject:MachineForDiscBrakeHydraulicBrakeDesignAbstractCoalmineupgradingequipmentasthekeyequipmentholdsanimportantpositioninmechanizedproductionofthetime.ThediscbrakeofthebrakingsystemforJKtype(2JK-3/11.5)hoisthavebeendesigned.Firstanalyzethebrakeoptions,selecttheoptimalscheme,thesecondforbrakematerial,liningmaterialselection,onceagain,thebrakepartdrawingforeachpartdesign,calculationandchecking.Sofartheminehoistbrakemachineusedmostlyhydraulicdiskbrake,analysisandmonitoringofthediscbrakeworkingreliability,isobjectiveandrealisticsignificance.Asthelatestdevelopmentofabrake,hydraulicdiscbrakeshavemanyadvantagessuchaswitheasytoadjustthebrakingtorque,compactstructure,commongoodsafeandhighreliability,isimportantinenhancingsecurity.Keywords:BrakingSystem;DiscBrake;ProbabilityofreliabilityIII目录1、绪论...............................................................................................................................................11.1、概述......................................................................................................................................11.1.1、提升机盘闸制动器的研究现状.......................................................................21.1.2、提升机盘式制动器的功能及可靠性要求...................................................22、盘闸制动器结构及其工作原理...............................................................................32.1、盘闸制动器的概述.......................................................................错误!未定义书签。2.1.1、盘式闸制动系统.......................................................................错误!未定义书签。2.1.2、提升机盘式制动器的结构型式及其原理....................错误!未定义书签。2.1.3、影响盘闸制动器制动力矩的因素...................................错误!未定义书签。2.1.4盘式制动器的故障类型及预防措施..................................错误!未定义书签。3、制动器受力分析、标准件的选取计算.............................................................43.1制动器性能参数...............................................................................................................53.2、摩擦片材料的选取：................................................................................................53.3、制动器液压缸的结构与设计计算：................................................................63.3.1、缸筒主要几何尺寸设计计算：.......................................................................63.3.2、液压缸结构参数的计算：.................................................................................73.3.3、液压缸的密封选取：.............................................................................................8IV3.3.4、活塞与活塞杆连接衬板的螺栓选取与校核计算：.............................103.4、碟簧的选择和设计计算：...................................................................................123.4.1、蝶形弹簧的特点及应用：...............................................................................123.4.2蝶形弹簧的计算：..................................................................................................134、制动器整体外形结构设计：...................................................................................164.1、摩擦片的结构尺寸....................................................................................................164.1.1、摩擦片尺寸的确定...............................................................................................164.1.2摩擦片的联接方式：铆接的强度校核..........................................................164.2、摩擦片衬板的结构尺寸...........................................................................................174.2.1、摩擦片衬板的外形尺寸确定..........................................................................174.2.2、摩擦片衬板连接螺栓设计计算：................................................................184.3、衬板的结构尺寸设计：.............................................................................................194.4、液压缸油缸结构尺寸的确定：.........................................................................204.5、间隙调整螺母校核与计算：..............................................................................204.6、制动器外壳的结构计算：...................................................................................214.7、端盖尺寸设计计算：..............................................................................................224.7.1、端盖的材料及结构尺寸的确定.....................................................................224.7.2、端盖螺栓布置及选取计算：..........................................................................22V4.8制动器安装板...................................................................................................................244.8.1、制动器安装板材料的选取...............................................................................244.8.2、安装板与外壳的焊接强度校核：................................................................254.8.3、影响焊缝强度的因素和提高焊缝强度的结构措施：........................254.8.4、制动器安装时所需螺栓设计：.....................................................................265、设计中配合公差选取计算：...........................
