I摘要本论文所研究的题目是JWB100滚珠丝杠升降机结构设计。主要是对蜗轮蜗杆、蜗轮丝杠的传动部分进行设计,以丝杠、蜗杆、蜗轮为主要的研究对象,对其工作受力性,材料的强度、刚度、韧性和散热性等进行了分析,并以升降机装置的使用特点及用途出发,确定了以蜗轮蜗杆、蜗轮丝杠两种传动装置为主要传动的设计方案,制定了蜗轮、蜗杆、丝杠之间的结构设计。完成结构设计后,用画图辅助工具AutoCAD绘制了3张A0图纸,清楚地表达了JWB100滚珠丝杠升降机的结构特点和使用性能。设计的蜗轮丝杆升降机即可以单台使用,也可以组合使用。能按一定程序准确地控制调整提升或推进的高度,可以用电动机或其他动力直接带动,也可以手动。它有不同的结构形式和装配形式,该装置可以自锁。广泛应用于机械、冶金、建筑、水利设备等行业,具有结构紧凑、体积小、重量轻、动力源广泛、无噪音、安装方便、使用灵活、功能多、配套形式多、可靠性高、使用寿命长等许多优点。关键词:升降机;丝杠;蜗轮;蜗杆IIAbstractThepaperstudiesonthetopicofJWB100Ballscrewelevatordesign.Mainlyonthewormgear,wormgearscrewtransmissionpartsofthedesign,withtheleadscrew,worm,wormgearasthemainresearchobject,itsworkforce,materialstrength,stiffness,toughnessandthermalperformancewereanalyzed,andtheliftdevicecharacteristicsanduse,todeterminethewormgear,wormscrewtwotransmissiondevicesasthemaintransmissiondesign,developedawormgear,worm,screwbetweenthestructuraldesign.Tocompletethestructuredesign,drawingauxiliarytoolfordrawingAutoCAD3A0drawings,clearexpressionoftheJWB100Ballscrewliftstructurecharacteristicsandperformance.Designofthewormscrewliftthatcanbeusedinsinglemachine,alsocanbeusedincombination.Accordingtocertainprocedurestoaccuratelycontroltherestructuringtoenhanceorpromoteheight,canbeusedtodirectlydrivethemotororotherpower,andcanalsomanually.Ithasdifferentformsofstructureandformoftheassembly,thedevicecanlock.Widelyusedinmachinery,metallurgy,construction,waterconservancyfacilitiesandotherindustries,hastheadvantagesofcompactstructure,smallvolume,lightweight,widerangeofpower,nonoise,convenientinstallation,flexibleuse,multiplefunctions,supportingform,highreliability,longlifeandmanyotheradvantages.Keywords:Elevator;Screw;Worm;CraneIII目录摘要.......................................................................................................................IAbstract.........................................................................................................................II第1章引言.................................................................................................................11.1蜗轮丝杆升降机设计概论.............................................................................11.1.1蜗轮丝杆升降机设计概论....................................................................11.1.2蜗轮丝杆升降机型号、规格及表示方法............................................11.2国内、外现状及发展趋势.............................................................................11.2.1国内现状及发展趋势..........................................................................11.2.2国外现状及发展趋势..........................................................................31.3本文研究的主要内容....................................................................................4第2章传动装置总体设计.........................................................................................52.1传动方案设计.................................................................................................52.2电动机的选择设计.........................................................................................52.2.1电动机的选择类型..............................................................................52.2.2确定传动装置效率..............................................................................52.2.3选择电机的型号..................................................................................62.2.4计算传动装置的运动和动力参数......................................................7第3章滚珠丝杠传动的设计...................................................................................93.1滚珠丝杠与滑动丝杠对比.............................................................................93.2滚珠丝杠传动的设计.....................................................................................93.2.1滚珠丝杠副的工作原理、特点及结构形式........................................93.2.2滚珠丝杠副的选用及计算..................................................................103.3螺母的设计...................................................................................................183.3.1选取螺母材料....................................................................................183.3.2确定螺母的高度................................................................................183.3.3确定螺文工作圈数............................................................................193.3.4螺母的实际高度................................................................................193.3.5螺母螺纹牙的强度计算....................................................................193.3.6螺母外径与凸缘的强度计算............................................................21第4章圆弧圆柱蜗杆传动设计...............................................................................244.1圆弧圆柱蜗杆传动设计概述......................................................................24IV4.1.1圆弧圆柱蜗杆传动的特点...............................................................244.2圆弧圆柱蜗杆传动的主要参数及其选择..................................................244.2.1圆弧圆柱蜗杆的参数及几何尺寸计算...........................................254.3圆弧圆柱蜗杆传动强度设计......................................................................264.4圆弧圆柱蜗杆刚度计算..............................................................................304.5精度等级公差和表面粗糙度的确定......................
