1本科毕业设计(论文)题目:多功能制茶机机械结构设计院(系)机电工程学院专业机械设计制造及其自动化班级080210姓名学号080210101导师2012年6月1多功能制茶机机械结构设计摘要在各方面日益现代化的今天,,制茶机也应该在技术上不断改进,向多功能、自动化、机电一体化方向发展。既能满足茶叶制成的一系列过程,包括对茶叶的杀青、理条、压扁、成型等作业,而且机械结构简单、操作简单,容易维修和维护。此制茶机以电动机为动力源来获得一个速度,然后通过一个二级减速装置获得合理的速度,再通过偏心轮、连杆使料仓可以来回运动。所以电动机的选取和二级减速装置的选取都是该设计的主要任务。最终经过计算分析分别选择单相异步电动机JY7134型和带传动形式。再设计一调速轮使其可以改变使料仓的速度并且可以在一定的幅度内调节。经过分析,确定调速轮安装在电动机输出端可以改变中心距来调速,料仓采用槽锅式。总的来说就是通过各控制系统可以使其在机体上进行可调速的来回运动,再加上料仓的功能来实现其对茶叶的杀青、理条、压扁、成型等作业。本机械将单片机的体积小、功耗低、价格低、品种规格系列化、硬件具有广泛的通用性、有专门的开发系统等优点结合起来,对制茶机的炒制方法跟对炒锅温度的控制结合在一起,实现了自动化生产。关键词:制茶机;多功能;机械结构;单相异步电动机;带传动形式2MultifunctionalteamachinemechanicalstructuredesignAbstractInallaspectsofthemodernizationoftoday,andteaalsoshouldmakecontinuousimprovementintechnology,automation,electromechanicalintegrationdevelopmentdirection.functionalfryteateamadeaseriesoffunctionalmeetprocess,includingfortea,wrap,crushed,molding,andsimplestructure,simpleoperation,easymaintenanceandmaintenance.Thefunctionfrywithmotorpowerforteamachinetoobtainaspeed,thenthroughareasonablelevelofspeedreducerdevice,againthroughtheeccentric,connectingtomovebackandforthfarbunker.Sothemotorandreducerlevelistheselectionofequipment,themaintaskofthedesign.FinallythroughcalculationandanalysistochooseJY7134monopoleasynchronousmotorrespectivelyandbeltforms.Todesignaspeedwhichcanchangethewheelspeedandcanmakethemachineincertainrange.Throughanalysis,speedwheelsmotoroutputcanbeinstalledinthecenter,tochangespeedbyslotmachinepot.OverallfunctionmachineisthroughtheFriedteacanmakeitscontrolsysteminthebodytoandfroontheadjustable,plusthefunctiontorealizeitsbunkershotfortea,squash,molding,etc.Thismachinerythemonolithicintegratedcircuitvolumesmall,thepowerlosslow,thepriceislow,thevarietyspecificationseriation,thehardwarehasthewidespreadversatility,hasmeritandsoonspecialdevelopmentsystemunifies,friesthesystemmethodtothesystemteamachinewithtothewoktemperaturecontroltounifyintogether,hasrealizedtheautomatedproduction.Keywords:Stir-fryteamachine,monopoleasynchronousmotor,beltforms1主要符号表目录摘要....................................................IAbstract.........................................................II主要符号表1绪论..........................................................11.1前言.........................................................11.2国内外茶叶机械的发展状况以及控制技术的发展...................11.2.1国内茶叶加工机械发展现状...............................11.2.2国外茶叶加工机械发展现状...............................31.3主要工作内容.............................................52机械结构设计..................................................62.1机械结构方案设计............................................62.2部分零件设计计算:...........................................92.2.1确定电动机的型号及安装尺寸.............................92.2.2确定传动装置的总传动比和分配传动比....................112.2.3确定V带型号和带轮直径及中心距........................122.2.4轴的设计计算..........................................152.3主要的局部结构设计..........................................242.3.1传动装置中的主要传动轮................................242.3.3料仓的设计............................................246结论............................................................44参考文献.........................................................45致谢.............................................................472毕业设计(论文)知识产权声明..................................48毕业设计(论文)独创性声明....................................49附录..............................................................501摘要................................................................1Abstract............................................................2主要符号表......................................................11绪论.............................................................11.1综述.........................................................11.1.1毕业设计的题目.........................................11.1.2毕业设计的目的.........................................11.2题目背景及研究意义.......................................11.3国内外茶叶加工机械发展现状...................................21.3.1国内茶叶加工机械发展现状...............................21.3.2国外茶叶加工机械发展现状...............................21.4毕业设计(论文)的主要内容与要求............................31.4.1毕业设计的主要内容.....................................31.4.2毕业设计的要求.........................................32机械结构设计......................................................12.1本课题研究的主要内容.......................................12.2拟采用的研究方案、研究方法或措施............................11、压头式茶炒制结构..........................................12、扁形茶炒制结构............................................22.2部分零件设计计算:..........................................52.2.1确定电动机的型号及安装尺寸.............................52.2.2确定传动装置的总传动比和分配传动比.....................72.2.3确定V带型号和带轮直径及中心距.........................82.2.4轴的设计计算..........................................112.3主要的局部结构设计.........................................192.3.1传动装置中的主要传动轮................................192.3.2料仓的设计............................................206结论..............................................................1参考文献............................................................1致谢......................................................
