学号：200313160211毕业设计说明书设计题目：带式输送机的设计学生姓名：李亮专业班级：03机械2班学院：轻工学院指导教师：林艳华副教授2006年06月15日摘要摘要本设计为带式输送机的设计，以低制造成本、结构简便、安全可靠为设计宗旨，在采用传统的带式输送机的设计方法、设计数据的同时采用了部分先进的新型带式输送机的计算方法及计算数据。本设计在托辊组选型设计部分，通过对带式输送机托辊组间距的合理确定及优化布置，大大减少了托辊组用量。承载段托辊组由原来的1000组减少到400组，回程段也相应地由原来的500组减少到200组，极大地降低了制造成本、维护成本，简化了结构，提高了运行的可靠性。拉紧装置设计部分，通过分析研究各种拉紧装置的优缺点来设计拉紧装置。把重锤车式拉紧和绞车拉紧结合起来使用，在不提高成本的基础上综合了两种拉紧方式的优越性。带式输送机驱动装置配置过高是一种资源浪费，而配置过低又会严重影响输送机寿命，所以选择合理的驱动装置、降低维修工作量和运营成本是选择驱动装置的关键。本设计综合分析研究了几种驱动装置的优缺点，合理选配了Y型电动机+调速型液力偶合器+减速器型驱动装置。了解和掌握带式输送机输送带跑偏原因及纠偏方法，对保证带式输送机的安全运行是非常重要的。本设计调偏装置设计部分就以上问题分析了输送带跑偏的原因及调偏原理并提出了解决跑偏的有效措施。关键词：带式输送机；托辊间距；拉紧；驱动；调偏AbstractIAbstractThisdesignisthedesignofthebeltconveyer,concentrateonlowmanufacturingcosts,simplestructureandreliabledesignwhichhaveadoptedenumerateddataandthedesignmethodofadvancedbeltconveyerswhileadoptingdesigndataandthedesignmethodofthebeltconveyeroftradition.Designinthepartofbearingrollerselecting,greatlyreducedthequantityofbearingrollergroupsbythereasonablydetermineandoptimizationarrangeofacrossblockofbearingrollergroups.Thebearinggroupsfrom1000groupsoforiginaldecreasinggoto400groups,thesectionofreturntripalsogoesto200groupscorrespondinglyby500groupsoforiginaldecreasing.Inpullinstallationdesignpart,selectpullinstallationdesignbyanalysisadvantagesandshortcomingsofvariouspullinstallation.Combinehammervehiclepullinstallationtowinchpullwithoutincreasingcost,asaresult,synthesizedthesuperitiesofbothtwo.It’sakindofresourcewastetousehighdispositionofactuatingdeviceforbeltconveyer,butlowdispositionwouldseriousinfluenceconveyerlife,soselectactuatingdevicereasonablyisveryimportant.AtlastchoosethemotorofYmodel+hydrauliccoincidencewareofspeedadjustment+gearreducerasactuatingdevices.Beltconveyerisamaintransportequipment,analysesthereasonsofconveyerbeltofftracking,putsforwardimprovingmeasuresandprecautionstoensurethesafetyoperationofbeltconveyer.KeyWords：beltconveyer,span,pull,actuatingdevice,offtracking目录I目录摘要.............................................................................................................................IAbstract...........................................................................................................................I1绪论........................................................................................................................12输送机主要部件的选型与设计计算........................................................................52.1设计的原始数据............................................................................................52.2输送机带速的选择........................................................................................52.3输送带宽度的计算选择................................................................................52.4输送机输送能力的计算................................................................................72.5功率计算........................................................................................................82.5.1传动滚筒轴功率计算..........................................................................82.5.2附加功率计算......................................................................................82.5.3电动机功率计算..................................................................................92.6输送带的计算选型......................................................................................102.6.1输送带的结构....................................................................................102.6.2覆盖胶的性能及适用情况................................................................122.6.4最大张力计算....................................................................................132.6.5输送带层数计算................................................................................142.7滚筒直径及托辊组的选择计算..................................................................162.7.1传动滚筒直径的确定........................................................................162.7.2改向滚筒直径的确定...............................................................................172.7.3托辊组的设计选择............................................................................182.8输送机驱动装置的设计..............................................................................192.8.1带式输送机的启动过程分析............................................................192.8.2大型带式输送机对驱动装置的要求................................................212.8.3现有驱动装置及其分类....................................................................212.8.4带式输送机各种驱动方式的比较研究............................................222.8.5确定驱动方式....................................................................................242.8.6电动机的选择计算............................................................................272.8.7调速型液力耦合器的选型................................................................272.8.8减速器的计算选型............................................................................282.9带式输送机拉紧装置的设计......................................................................30目录II2.9.1拉紧装置的作用................................................................................302.9.2各种拉紧装置的性能比较及拉紧装置的确定.....................
