工件步进输送机设计

I工件步进输送机设计摘要工件步进输送机用于间歇地输送工件，到达预定位置。传统输送机通过电动机采用普通减速器多级变速实现，传动装置结构尺寸大。为了使装置结构紧凑，传动效率高，本文完成了采用行星减速器为传动系的步进输送机的设计与研究。本文对工件步进输送机的研究要点如下：（1）介绍了现有工件输送机的类型、发展趋势和研究本课题的目的、意义，分析了输送机国内外的研究现状。（2）在完成对工作机构的设计、确定电动机的类型的情况下，建立了两种传动系减速方案，通过方案对比，择优选择出采用行星齿轮减速器的步进输送机传动方案，并对此方案的可行性进行了分析。（3）进行了工件步进输送机的总体结构设计，重点设计了行星齿轮减速器总体及部分零件的结构，并详细绘制了关键零件的工作图。（4）同时运用计算机辅助软件对工作机构及传动系进行运动仿真分析，为进一步改进传动结构提供理论依据。关键词：工件步进输送机电动机行星齿轮减速器设计仿真IIWorkpiecesteppingconveyordesignAbstractWorkpiecesteppingconveyorusedintermittentlytransportationworkpiece,arrivedatthescheduledposition.Traditionalconveyorbyusingcommonreducermultistagevariablespeedmotors,transmissiondevicestructuresizerealization.Inordertoachievehightransmissionefficiency,wecompletedaplanetaryreducerfortransmissionbytheworkpiecesteppingconveyordesignandresearch.Thisarticleonthesteppingconveyorresearchpointsasfollows:(1)Introducesexistingworkpiece,thetypesofbeltconveyordevelopmenttrend,andstudyofthissubject,analyzesthepurposeandsignificanceoftheresearchsituationathomeandabroad.(2)Afterfinishingthedesignofworkingmechanismanddeterminethetypeofsituationmotor,setuptwokindsoftransmissiondecelerationscheme,throughtheschemecontrast,technicalselectedtheplanetgearreducersteppingconveyortransmissionscheme,andthefeasibilityofthisplanareanalyzed.(3)Underwentworkpiecesteppingconveyortheoverallstructuredesign,focusingontheplanetgearreducerdesignofthestructureofoverallandparts,anddetailedthekeypartsmappedtheworkingdrawing.(4)Atthesametimeusingcomputer-aidedsoftwaretoworkinstitutionsanddrivetrainmotionsimulationanalysis,forfurtherimprovedtransmissionstructureprovidestheorybasis.Keywords:workpiecesteppingconveyor;motor;planetarygearreducer;design;simulationIII目录1.绪论....................................................................I1.1引言.................................................................11.1.1输送机的类型及特性介绍............................................11.1.2工件步进输送机的工作原理..........................................21.1.3输送机的发展趋势..................................................31.2研究的目的和意义......................................................31.3国内外研究现状........................................................41.4主要研究内容..........................................................41.4.1课题任务..........................................................41.4.2课题所要完成的主要工作............................................52.步进输送机方案设计...................................................62.1工作机构的设计与分析..................................................62.1.1工作机构型式的选择................................................62.1.2设计机构的具体尺寸................................................62.1.3机构的速度分析....................................................82.2选择电动机............................................................92.2.1选择电动机的类型..................................................92.2.2选择电动机的容量..................................................92.3传动方案的对比分析及优选.............................................102.3.1选择传动形式.....................................................102.3.2两种传动方案对比分析及优选........................................103.行星齿轮减速器性能参数设计..........................错误!未定义书签。3.1行星传动的齿数分配....................................错误!未定义书签。3.2闭式圆柱齿轮传动的设计计算............................错误!未定义书签。3.2.1高速级计算........................................错误!未定义书签。3.2.2几何尺寸计算......................................错误!未定义书签。3.2.3验算齿根弯曲强度（a-c轮）.........................错误!未定义书签。3.2.4齿轮的圆周速度....................................错误!未定义书签。IV3.3轴的结构尺寸设计及校核................................错误!未定义书签。3.3.1高速轴设计........................................错误!未定义书签。3.3.2行星轮轴结构设计..................................错误!未定义书签。3.3.3低速轴结构设计....................................错误!未定义书签。3.4滚动轴承的选择与校核..................................错误!未定义书签。3.4.1确定轴承型号......................................错误!未定义书签。3.4.2根据寿命校核......................................错误!未定义书签。3.5减速器其他主要零部件结构设计..........................错误!未定义书签。3.5.1内齿圈浮动........................................错误!未定义书签。3.5.2行星架结构........................................错误!未定义书签。4.工件步进输送机总体设计..............................错误!未定义书签。5.减速器传动零件的三维设计及运动仿真.................错误!未定义书签。5.1减速器传动零件实体造型................................错误!未定义书签。5.1.1高速轴实体设计（图5.1.1）.........................错误!未定义书签。5.1.2行星轮实体设计（图5.1.2）.........................错误!未定义书签。5.1.3行星架实体设计（图5.1.3）.........................错误!未定义书签。5.1.4内齿轮b实体设计（图5.1.4）.......................错误!未定义书签。5.1.5内齿轮e实体设计（图5.1.5）.......................错误!未定义书签。5.1.6齿轮联轴器实体设计(图5.1.6).......................错误!未定义书签。5.1.7低速轴实体设计（图5.1.7）.........................错误!未定义书签。5.2传动零件、四杆机构装配................................错误!未定义书签。5.3运动仿真及分析........................................错误!未定义书签。5.3.1设置运动环境......................................错误!未定义书签。5.3.2进行运动仿真......................................错误!未定义书签。5.3.3获取分析结果......................................错误!未定义书签。5.3.4分析运动仿真结果，验证输入/输出值与计算值是否吻合.错误!未定义书签。结语.......................................................错误!未定义书签。参考文献..................................................错误!未定义书签。致谢......
