齐齐哈尔大学毕业设计(论文)I摘要本设计为封盖机设计,主要应用于白酒企业,对白酒进行封盖,其生产率为2000瓶/小时,所适应的瓶高为60-100mm,瓶口直径为Φ22-26mm。该机器由电动机提供动力,电机选用鼠笼式三相异步电动机,工作时,通过两条传动链输出:一条经过一级带传动和蜗轮蜗杆减速器驱动曲柄滑块机构使电动机转动转变为直线往复运动;另外一条是电动机通过两级带传动驱动滚压头中心轴做旋转运动,从而实现滚压头同时做旋转、直线运动,实现对瓶口的封盖。曲柄滑块机构具有结构简单、加工容易、维修方便、经济实用的优点,在机械设备中应用广泛。本设计中,通过对平面曲柄滑块机构的数学建模,用MATLAB编程,输入曲柄滑块机构的机构参数和运动参数,实现对整个机构运动过程的仿真分析。关键词:封盖机;曲柄滑块;蜗轮蜗杆;带传动齐齐哈尔大学毕业设计(论文)IIAbstractThisdesignforsealingmachinedesign,mainlyappliesintheliquorenterprise,toblockofliquor,itsproductivityfor2000bottles/hour,thebottletohighfor60-100mm,andthebottletodiameterforΦ22-26mm.Thismachinepoweredbymotor,motorselectionrattraptypethree-phaseasynchronousmotor,working,thisthroughtwotransmissionchainoutput:Onepassinglevel1beltandwormreducerdriveslider-crankmechanismforlinearmotorrotationtransformationtoreciprocatingmovement;anotheristheelectromotorthroughtwo-stagebeltdriverollerheaddorotationalmotion,soastorealizethepressureheadalsodorollrotation,linearmotion,realizestomouthsealing.Slider-crankmechanismhassimplestructure,easyprocessing,maintenanceisconvenient,economicalandpracticaladvantages,iswidelyusedinmechanicalequipment.Thisdesign,throughtheplaneslider-crankmechanismmathematicalmodeling,MATLABprogramming,inputslider-crankmechanismstructureparametersandthemotionparametersofthewholeorganization,realizethemovementprocessofthesimulationanalysis.Keywords:Sealingmachine;Slider-crank;Worm;Belttransmission齐齐哈尔大学毕业设计(论文)I目录摘要..................................................................IABSTRACT...............................................................II目录..................................................................I第一章绪论.............................................................1第二章总体方案设计....................................................22.1液压传动档案........................................................22.2气压传动方案........................................................22.3机械传动方案........................................................32.3.1凸轮传动机构....................................................32.3.2曲柄滑块传动方案.................................................42.4设计创新型传动方案..................................................4第三章电动机的选择....................................................63.1电动机类型的选择....................................................63.1.1电动机的容量选择.................................................63.1.2确定电动机型号.................................................73.1.3电动机的外形尺寸...............................................83.2传动系统运动参数及动力参数的计算...................................83.2.1确定传动系统各部分合理的传动比.................................83.2.2计算运动参数(各轴转速).........................................93.2.3计算动力参数...................................................9第4章带传动的设计及计算.............................................114.1确定设计的功率.....................................................114.2选择带型..........................................................114.3确定带轮基准直径..................................................124.3.1初选小带轮基准直径............................................134.3.2验算带速......................................................134.3.3计算大带轮基准直径............................................134.3.4确定中心距和带的基准长度......................................134.3.5验算主动轮包角................................................144.3.6确定带的根数..................................................154.3.7确定带的预紧力................................................154.3.8计算带传动作用在轴上的力......................................164.4带轮结构的设计....................................................164.4.1小带轮结构设计................................................16齐齐哈尔大学毕业设计(论文)II4.4.2大带轮结构设计................................................18第5章蜗杆传动设计....................................................205.1蜗杆传动类型选择...................................................205.2选择材料..........................................................215.3蜗杆传动的主要参数及其选择........................................215.3.1模数和压力角..................................................225.3.2蜗杆的分度圆直径..............................................225.3.3蜗杆头数......................................................235.3.4导程角........................................................235.3.5传动比和齿数比................................................235.3.6蜗轮齿数......................................................245.3.7蜗杆传动的标准中心距..........................................245.3.8参数的选定....................................................245.4蜗杆传动的几何尺寸计算............................................245.4.1蜗杆传动的受力分析............................................275.4.2蜗轮齿面接触疲劳强度计算......................................295.4.3蜗轮齿根弯曲疲劳强度计算......................................315.4.4蜗杆的刚度计算..................................................315.4.5蜗杆传动滑动速度计算............................................32第六章匀速直线往复机构的设计与计算...................................346.1齿轮类型的选择....................................................346.2往复运动的行程设计.................................................356.3360度全齿齿轮的设计...............................................356.4180度版齿
