锻锤三缸镗缸机的研制—镗轴组件设计摘要本课题研究的是专门用于镗削加工C41-2000型空气锤的三个气门孔的专用镗床，设计对主传动系统的设计部分与镗轴的设计部分作了详细说明，对一些辅助装置也作了相应的描述。设计从总体布局开始引出，通过认真研究、分析了设计任务书后，针对任务书的要求进行了课题调研和现场考察，提出了传动设计方案。确定电动机的功率，分析各种传动下的主轴的转速，转矩以及所消耗的功率。确定传动过程和传动装置，选择合理的齿轮传动，选择了齿轮的齿数及齿宽，最后对齿轮的齿数和模数的校核。在主轴的设计中，初选结构参数，确定组件的布局，然后在已确定主轴结构尺寸的基础上，进行主轴的强度和刚度的校核。正确选择轴承，并对轴承进行校核验算。本文将重点叙述主变速传动设计部分和镗轴的设计部分。主变速系统设计进行中，这些部分将以工作缸镗轴变速箱输入轴为主要设计和校验对象，在此基础上尽量扩大轴的尺寸，以满足其它各轴的设计要求，轴径大小与长度的选择、轴的轴向定位、周向定位、轴的强度校核为本章的主要内容。镗轴设计中，以镗轴的组件的设计为重点，以镗轴的悬伸量选择，跨度计算和刚度的计算展开，并对镗轴的性能和基本要求等做了粗略介绍。关键词：专用机床三缸镗床主轴传动Forginghammerthree-cylinderboringlathedevelopment—boringaxismoduledesignAbstractWhatthistopicresearchisusesinprocessingtheC41-2000airhammerpneumatichammer'sthreevalveportspecial-purposeboringlathesboringspecially,designedhasgiventhedetailedexplanationtothemasterdrivesystem'sdesignpartandtheboringaxisdesignpart,hasalsomadethecorrespondingdescriptiononsomeauxiliaryunits.Thedesignstartsfromtheentiredistributiontodrawout,afterstudies,hasanalyzedthedesignprojectdescriptionearnestly,inviewoftheprojectdescriptionrequesthascarriedonthetopicinvestigationandstudyandthesceneinspection,proposedthetransmissiondesignproposal.Thedefiniteelectricmotor'spower,analyzesundereachtransmissionmainaxle'srotationalspeed,thepowerwhichthetorqueaswellasconsumes.Thedefinitetransmissionprocessandthetransmissiondevice,choosethereasonablegeardrive,haschosengear'snumberofteethandthetoothwidth,finallycountergear'snumberofteethandmodulusexamination.Inmainaxle'sdesign,primaryelectiondesignparameter,definitemodule'slayout,then,determinedthatthemainaxlestructuresizeinthefoundation,carriesonmainaxle'sintensityandtherigidityexamination.Choosesthebearingcorrectly,andcarriesontheexaminationcheckingcalculationtothebearing.Thisarticlewillnarratethemainvariabletransmissiondesignpartandtheboringaxisdesignpartwithemphasis.Themainspeedchangesystemdesigncarrieson,thesepartstakewillworkthecylinderboringaxisgearboxinputaxisasthemaindesignandtheverificationobject,basedonthisexpandsm
