蜗轮蜗杆减速器课程设计(含图纸)

I蜗轮蜗杆减速器设计摘要通过对减速器的简单了解，开始学习设计齿轮减速器，尝试设计增强感性认知和对社会的适应能力，及进一步巩固已学过的理论知识，提高综合运用所学知识发现问题、解决问题，以求把理论和实践结合一起，为以后的工作和更好的学习积累经验。学习如何进行机械设计，了解机械传动装置的原理及参数搭配。学习运用多种工具，比如CAD等，直观的呈现在平面图上。通过对圆柱齿轮减速器的设计，对齿轮减速器有个简单的了解与认知。齿轮减速器是机械传动装置中不可缺少的一部分。机械传动装置在不断的使用过程中，会不同程度的磨损，因此要经常对机械予以维护和保养，延长其使用寿命，高效化的运行，提高生产的效率，降低生产的成本，获得最大的使用效率。关键词：机械传动装置、齿轮减速器、设计原理与参数配置IIInthispaperThroughthesimpleunderstandingofthespeedreducer,startedlearningdesignofgearreducer,attempttodesignenhancetheperceptualcognitionandabilitytoadapttosociety,andfurtherconsolidatethelearnedtheoryknowledge,toimprovetheintegrateduseofknowledgediscoveryandsolveproblems,inordertocombinetheoryandpracticetogether,forthelaterworkandbetterlearningexperience.Learnhowtodomechanicaldesign,tounderstandtheprincipleofmechanicaltransmissiondeviceandparametercollocation.Studyusingavarietyoftools,suchasCAD,intuitivepresentonthefloorplan.Throughthedesignofcylindricalgearreducer,gearreducerisasimpleunderstandingandcognition.Gearreducerisanindispensablepartofinmechanicaltransmissiondevice.Mechanicaltransmissiondeviceinuseprocess,willbedifferentdegreeofwearandtear,sooftentomechanicalmaintenanceandmaintenance,prolongtheservicelifeandhighlyeffectiveoperation,improveproductionefficiency,reducethecostofproduction,achievemaximumefficiency.Keywords:mechanicaltransmissiongear,gearreducer,thedesignprincipleandparameterconfigurationIII目录摘要............................................................................IInthispaper..................................................................II1．电机选择........................................................................12．选择传动比......................................................................22.1总传动比....................................................................22.2减速装置的传动比分配............................................................23．各轴的参数......................................................................23.1各轴的转速......................................................................23.2各轴的输入功率..................................................................33.3各轴的输出功率..................................................................33.4各轴的输入转矩..................................................................33.5各轴的输出转矩..................................................................33.6各轴的运动参数表................................................................44.蜗轮蜗杆的选择...................................................................44.1选择蜗轮蜗杆的传动类型..........................................................44.2选择材料........................................................................44.3按计齿面接触疲劳强度计算进行设..................................................44.4蜗杆与蜗轮的主要参数与几何尺寸..................................................64.5校核齿根弯曲疲劳强度............................................................74.6验算效率........................................................................74.7精度等级公差和表面粗糙度的确定..................................................85．圆柱齿轮的设计..................................................................85.1材料选择........................................................................85.2按齿面接触强度计算设计..........................................................85.3计算............................................................................95.4按齿根弯曲强度计算设计.........................................................10IV5.5取几何尺寸计算.................................................................116．轴的设计计算..................................................................126.1蜗杆轴.........................................................................126.1.1按扭矩初算轴径............................................................126.1.2蜗杆的结构设计............................................................126.2蜗轮轴.........................................................................146.2.1输出轴的设计计算..........................................................146.2.2轴的结构设计..............................................................146.3蜗杆轴的校核...................................................................166.3.1求轴上的载荷..........................................................166.3.2精度校核轴的疲劳强度......................................................186.4蜗轮轴的强度校核...............................................................216.4.1精度校核轴的疲劳强度......................................................236.4.2精度校核轴的疲劳强度......................................................237.滚动轴承的选择及校核计算.........................................................267.1蜗杆轴上的轴承的选择和寿命计算.................................................277.2蜗杆轴上轴承的选择计算.........................................................288.键连接的选择及校核计算...........................................................318.1输入轴与电动机轴采用平键连接...................................................318.2输出轴与联轴器连接采用平键连接.................................................318.3输出轴与蜗轮连接用平键连接.....................................................329．联轴器的选择计算................................................................329.1与电机输出轴的配合的联轴器.........
