齿辊式分级破碎机设计资料电子版

毕业设计（论文）1摘要我国目前原煤的破碎一般采用锤式破碎机或齿辊式破碎机。锤式破碎机是以高速运动的锤头打击物料，在破碎腔内受到相互破碎冲击和剪切，可控性很差，容易产生过粉碎，而且对入料度有限制，不适合煤炭的粗、中碎作业。而齿辊式破碎机是在齿的作用下对物料进行劈碎，破碎后的物料直接排出，因此破碎粒度比较均匀。目前的双齿辊破碎机由于整体结构的不合理和破碎齿磨损快不能修复等原因，使用效果大大降低甚至很差。FP50AL齿辊式分级破碎机是在吸取国内外先进技术的基础上研制和设计出来的高强力破碎机，很有发展前景和市场前景。关键词：双齿辊破碎机，破碎机，产品粒度FP50AL齿辊式分级破碎机总体结构设计2AbstractMycurrentcoalwasbrokengenerallyusinghammer-Breakersorteethroller-Breakers.Hammer-Breakersisthedeadagainsthighvelocitymaterialsintheshattereddebrisimpactandshearedbymutualbroken,controllabilitypoorhadtosmasheasily,buttherearerestrictionsonthesizenotsuitableforcoalrough,Chinesebrokenoperations.Andteethroller-Breakersteethintheroleofmaterialsreturnedbroken,thebrokenmaterialdirectlyemit,brokengranularitymoreevenly.Thecurrenttwo-toothrollerBreakersandtheoverallstructureoftheirrationalcannotrepairbrokenteethwearfasterreasons,theuseofsignificantlyreducedorevenpoor.FP50ALteethrollerBreakersinlessonsandonthebasisofadvancedtechnologyanddesignedtodevelophigh-strongBreakers,adevelopmentprospectsandmarketprospects.Keyword：Doubletoothedrollcrusher,Rollcrusher,Productgrainsize毕业设计（论文）3目录前言.....................................................................11绪论....................................................................21.1选题的目的和意义...................................................21.2破碎机的概述.......................................................21.2.1破碎的目的...................................................21.2.2齿辊破碎机的特点和分类.......................................31.2.3齿辊破碎机的工作原理.........................................31.2.4双齿辊破碎机的基本构造.......................................41.2.5齿辊破碎机的主要部件.........................................51.3齿辊破碎机的发展概况...............................................61.3.11990年以前的齿辊式破碎机....................................61.3.21990年以后的齿辊式破碎机....................................71.3.3国外先进高效破碎机...........................................81.3.4结语.........................................................91.4本设计的主要内容...................................................92双齿辊破碎机总体设计方案...............................................102.1辊式破碎机的类型..................................................102.2双齿辊破碎机的工作原理............................................102.3双齿辊破碎机的传动方案的确定......................................102.4双齿辊破碎机的基本构造............................................113电机的选择.............................................................123.1性能与结构特点....................................................123.2适用范围..........................................................123.3安装方式..........................................................123.4型号含义..........................................................124液力偶合器的选用.......................................................134.1概述..............................................................134.2液力偶合器的选用..................................................134.2.1液力偶合器的使用情况........................................134.2.2限矩型液力偶合器的技术参数及安装尺寸........................135TH系列减速器的选型....................................................145.1计算传动比........................................................145.2确定减速器的额定功率..............................................145.3校核最大扭矩......................................................15FP50AL齿辊式分级破碎机总体结构设计45.4校核热平衡功率....................................................156联轴器的选用计算.......................................................176.1联轴器的概述......................................................176.2联轴器的使用位置..................................................176.3联轴器的选用计算..................................................176.2.1联轴器各转矩之间的关系......................................176.2.2联轴器1的选用计算..........................................186.2.3联轴器3的选用计算..........................................187主要零部件的设计与校核.................................................207.1键的强度核算......................................................207.1.1电机轴的键强度校核..........................................207.1.2液力偶合器的键的校核........................................207.1.3液力偶合器输出孔键的校核....................................217.1.4液力偶合器右侧联轴器左半部分键的强度核算....................217.1.5右半部分的键的核算..........................................217.1.6变速箱输出轴键的强度核算....................................227.2工作齿辊轴的设计计算..............................................227.2.1主轴的材料..................................................227.2.2根据转矩计算轴的最小直径....................................227.2.3.轴的弯曲刚度校核计算........................................238轴承的选择与校核.......................................................268.1液力偶合器两端的轴承校核..........................................268.1.1滚动轴承的当量动载荷计算....................................268.1.2轴承基本额定动载荷的校验....................................268.2齿辊轴轴承的校核..................................................278.2.1齿辊轴的重量计算............................................278.2.2齿辊轴所受外力计算..........................................279同步齿轮的设计与校核...................................................289.1选择齿轮的材料....................................................289.2模数的选取.....................................
