带式输送机毕业设计

本科毕业设计说明书DTL120-130-55带式输送机整体设计THEDTL120-130-55TAPETYPECONVEYOROVERALLDESIGN学院（部）：机械工程学院专业班级：机设07-9班学生姓名：梁本磊指导教师：陈加胜讲师2011年06月06日DTL120-130-55带式输送机的整体设计摘要本次毕业设计是关于DTL120-130-55带式输送机的整体设计。首先对胶带输送机作了简单的概述；并且简单介绍了带式输送机的工作原理和传动原理；接着分析了带式输送机的选型原则以及计算方法；然后根据这些设计准则与计算选型方法按照给定参数要求进行选型设计；接着对所选择的带式输送机各主要零部件进行了校核。普通型带式输送机由六个主要部件组成：传动装置，机尾和导回装置，中部机架，拉紧装置以及胶带。最后简单的说明了输送机的安装与维护。目前，胶带矿用带式输送机正超着长距离，高速度，低摩擦的方向发展，近年来出现的气垫式胶带输送机就是其中的一个。在胶带输送机的设计、制造以及应用方面，目前我国与国外先进水平仍有较大的差距，国内在设计制造带式输送机过程中存在着很多的不足。本次带式输送机设计的一般过程，对今后的选型设计工作有一定的参考价值。同时增加了查阅相关资料的能力，对于以后的深入学习有很大的价值。关键词：带式输送机；选型设计；主要部件THEDTL120-130-55BELTCONVEYORDESIGNABSTRACTThedesignisagraduationprojectabouttheDTL120-130-55beltconveyor.Atfirst,itisintroductionaboutthebeltconveyor,Andinbriefintroducedoperateprinipleanddriveprinipleoftapetypesonveyor.Next,itistheprinciplesaboutchoosecomponentpartsofbeltconveyor.Afterthatthebeltconveyorabaseontheprincipleisdesigned.Then,itischeckingcomputationsaboutmaincomponentparts.Theordinarybeltconveyorconsistsofsixmainparts:DriveUnit,JiborDeliveryEnd,TailEnderReturnEnd,IntermediateStructure,LoopTake-UpandBelt.Atlast,itisexplanationaboutfixandsafeguardofthebeltconveyor.Today,longdistance,highspeed,lowfrictionisthedirectionofbeltconveyor’sdevelopment.Aircushionbeltconveyorisoneofthem.Atpresent,westillfallfarshortofabroadadvancedtechnologyindesign,manufactureandusing.Therearealotofwastesinthedesignofbeltconveyor.Thegeneralprocessofthistapetypesonveyordesignhascertainreferenceworthtoaftertime'schosendesignoperate.Thecapabilitythatraisedtocheckrelateddataatthesametime,forlaterofthethoroughstudyhasverygreatworth.KEYWORD：beltconveyor，LectotypeDesign，mainparts目录摘要...............................................错误!未定义书签。ABSTRACT...........................................................31绪论.............................................错误!未定义书签。2带式输送机概述...................................................32.1带式输送机的历史与应用.....................................32.2带式输送机的分类与特点.....................................32.2.1带式输送机的适用条件与特点............................32.2.2带式输送机的分类......................................42.2.3各种带式输送机的特点..................................42.3带式输送机的类型与发展状况.................................52.3.1带式输送机的类型......................................52.3.2带式输送机的发展状况..................................72.4带式输送机的计算原理.......................................72.4.1带式输送机的工作原理..................................72.4.2带式输送机的传动原理..................................82.5带式输送机的结构和布置形式................................112.5.1带式输送机的结构.....................................112.5.2输送带的布置方式....................1错误!未定义书签。3带式输送机的验证设计计算.......................1错误!未定义书签。3.1原始数据与工作条件.......................1错误!未定义书签。3.2设计计算过程...............................错误!未定义书签。3.2.1输送带运输能力核算....................错误!未定义书签。3.2.2输送带宽度的核算.....................................223.3圆周驱动力................................................223.3.1计算公式.............................................223.3.2主要阻力计算.........................................233.3.3主要特种阻力计算.....................................253.3.4附加特种阻力计算.....................................263.3.5倾斜阻力计算.........................................273.3.5圆周驱动力计算.......................................273.4传动功率计算...............................................273.4.1传动轴功率计算.......................................273.4.2电动机功率计算.......................................273.5输送带张力................................................283.5.1输送带不打滑条件......................错误!未定义书签。3.5.2输送带下垂度校核.....................................303.5.3输送机各特性点张力计算...............................303.6传动滚筒、改向滚筒合张力..................................333.6.1改向滚筒合张力.......................................333.6.2传动滚筒合张力.......................................333.7传动滚筒最大扭矩..........................................333.8拉紧力....................................................343.9绳芯输送带强度校核.........................................344驱动装置的选用与设计............................................354.1传动装置的选用............................................354.2传动装置的选用............................................354.2.1传动装置的总传动比...................................354.2.2液力偶合器...........................................364.2.3联轴器................................错误!未定义书签。5带式输送机部件的选用............................................405.1输送带....................................................405.1.1输送带的分类：.......................................405.1.2输送带的连接.........................................415.2传动滚筒..................................................415.2.1传动滚筒的作用及类型.................................415.2.2传动滚筒的选型及设计.................................415.2.3传动滚筒结构设计.....................................425.2.4传动滚筒的直径验算...................................505.3托辊......................................................515.3.1托辊的作用与类型.....................................515.3.2托辊的选型...........................................535.3.3托辊的校核...........................................505.4制动装置..................................................575.4.1制动装置的
