JWB100滚珠丝杠升降机结构设计说明书

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........................................................................................83.1滚珠丝杠与滑动丝杠对比.................................................................................83.2滚珠丝杠传动的设计..........................................................................................83.2.1滚珠丝杠副的工作原理、特点及结构形式..........................................83.2.2滚珠丝杠副的选用及计算........................................................................93.3螺母的设计.........................................................................................................173.3.1选取螺母材料.........................................................................................173.3.2确定螺母的高度.....................................................................................173.3.3确定螺文工作圈数................................................................................173.3.4螺母的实际高度.....................................................................................173.3.5螺母螺纹牙的强度计算........................................................................183.3.6螺母外径与凸缘的强度计算................................................................19第4章圆弧圆柱蜗杆传动设计....................................................................................224.1圆弧圆柱蜗杆传动设计概述..........................................................................22IV4.1.1圆弧圆柱蜗杆传动的特点...................................................................224.2圆弧圆柱蜗杆传动的主要参数及其选择.....................................................224.2.1圆弧圆柱蜗杆的参数及几何尺寸计算..............................................234.3圆弧圆柱蜗杆传动强度设计.....................................................
