文档介绍：摘要本设计是NGW行星减速器的结构设计,用来传递两轴之间的运动和动力,并实现较大的传动比。对齿轮与中心轮组合的受力状况分析时,应引入不均载系数根据传动,工作扭矩,载荷,根据转速要求计算出齿轮的齿数,模数,分度圆直径,计算出传动齿的齿厚,齿面硬度,选择齿形,根据上述要求选定达到此要求的材料,并且做出经济效益最好的选择,再根据此材料的弹性影响系数,各传动齿轮接触疲劳强度极限,再对材料的选择正确与否做出校核,并且要满足减速器的使用寿命要求,计算中心距,确定行星轮系的周转圆半径及方向,得到各项数据后,依据设计要求结构大小,确定各部件相对位置,进入外箱体的设计,秉承体积最小,拆装方便的原则,定好主轴位置,窥视孔,润滑口在箱体上的位置,便于维修判断。[关键词]行星齿轮;行星机构;传动轴;arybodiesinseries,binationofinstitutions,totransferthetwo-,shouldbeintroducedundertheuneventransmissioncoefficient,thetorque,load,ordancewiththerequirementsinordertospeedthegearteeth,module,thecirclediameter,calculatedDriveToothtooththick,toothsurfacehardness,selectprofile,ordancewiththerequirementsoftheselectedmaterialtothisrequest,andmakethebestchoiceforcost-effective,thenthismaterialundertheimpactoftheflexibilityfactor,thetransmissiongearcontactfatiguelimit,Andthechoiceofmaterialstocheckwhetherornotcorrect,andtomeettherequirementsofthelifeofreducer,accordingtoloadandtransmissiontorquespindledrivecalculatedthediameterandlocation,srevolvingroundthecircleofradiusAnddirection,andspecifytheroundofthedirectionofrotation,getthedata,basedonthedesignrequirementsofsize,ponentsintothebox,thedesignishometothesmallest,tofacilitateentrytotheprincipleofthespindlegoodlocation,Peephole,Ilubricationintheboxonthelocation,easeofmainInadditiontogear,theworkloadofotherbearpartssuchastheaxis,keys,thebearings,alsohadadesignReduceraflange--,drivemore,,arybodiescanconveymorepowerandtherealizationofthelargertransmissionratio, 1选题背景 2总体设计方案设计
