軸承套圈專用車床主軸箱設(shè)計(jì)摘要作為主要的車削加工車床，軸承套圈專用車床是適合大批量生產(chǎn)，大功率，高效率的半自動(dòng)化車床，它主要用于軸承套圈的車削加工，也可用于加工盤類、短軸類、套類等零件，在該機(jī)床上采用多把刀具同時(shí)加工零件，也可采用仿型刀架加工各種成型表面。本設(shè)計(jì)主要針對(duì)液壓卡盤多刀仿型車床主傳動(dòng)系統(tǒng)進(jìn)行設(shè)計(jì)。主傳動(dòng)系統(tǒng)的功用是支撐主軸和傳動(dòng)其旋轉(zhuǎn)，并使其實(shí)現(xiàn)起動(dòng)、停止、變速、變向等。主傳動(dòng)系統(tǒng)的傳動(dòng)機(jī)構(gòu)包括定比機(jī)構(gòu)和變速機(jī)構(gòu)兩部分，前者僅用于傳遞運(yùn)動(dòng)和動(dòng)力，或進(jìn)行升速、降速，采用齒輪傳動(dòng)副；后者用來使主軸變速，采用滑移齒輪變速機(jī)構(gòu)，其結(jié)構(gòu)簡單緊湊，傳動(dòng)效率高。開停裝置用于控制主軸的起動(dòng)和停止。換向裝置用于改變主軸的旋轉(zhuǎn)方向。設(shè)計(jì)的內(nèi)容主要有機(jī)床主要參數(shù)的確定，傳動(dòng)方案和傳動(dòng)系統(tǒng)圖的擬定，對(duì)雙向片式摩擦離合器進(jìn)行設(shè)計(jì)，它是主軸的起動(dòng)和停止以及換向裝置，對(duì)離合器的主要零件摩擦片進(jìn)行計(jì)算和驗(yàn)算，利用CAD繪圖軟件進(jìn)行零件的設(shè)計(jì)和處理。關(guān)鍵詞：車床，床頭箱，換向，離合器。HYDRAULICMULTI-CHUCKLATHEBEDPROFILINGTOOLBOXDESIGNABSTRACTAsthemainlatheworklathe,speciallathesbearingringsaresuitableformassproduction,highpower,highefficiencyofsemi-automaticlathe,whichismainlyusedforturningbearingrings，andcanalsobeusedforprocessingdisktype,brachyaxistype,asetofkindandsoonInaddition，itusesmanycutterssimultaneouslytoprocessesthecomponents，andmayalsouseduplicatingtoolresttoprocesseachkindofformedsurfaceThisdesignmainlyaimsatthehydraulicchuckmulti-knifeshapinglatheheadstockMaindrivensystemistopropupthefunctionofitsrotationofaxisandthedriveandmakeitstart,stop,speedchange,direction-convertingetc.Thedrivingmechanismofmaindrivensystemmainlyincludetwoparts,constantproportionmechanismandgearshiftmechanism.Theheformerisonlyusedforthetransmissionofmotionandpowerthroughgearpair,orhoistingspeed,settlingvelocity；Thelatterisusedtochangethevelocityofspindlethroughshiftmechanismofslippinggear,thestructureofwhichissimpleandcompact,withhightransmissionefficiencyTheshartingandbrakingdevicesareusedtocontrolthespindleofitsstartandstopThereversingdeviceisusedtoalterthedirectionofspindlerotationThemaincontentsofthemachinetoolcontainsettlesoftheparameter,toascerttheprojectoftransmissionanddrawingofdrivensystem，thedesignoffrictionclutchofdouble-disk,whichisthedeviceofstart,stopandcommutationforthespindle，calculationandcheckingforthemajorpartsandfrictionplate，utilizationofCADpaintingsoftwaretocarryonthedesignandprocessingofpartsKEYWORDS：lathe，headstock，direction-converting，目錄前言11.1車床的用途和運(yùn)動(dòng)31.2車床的分類3第1章概述51.1軸承環(huán)卡盤多刀車床的用途51.2機(jī)床的總體布置51.3機(jī)床的主要參數(shù)5第2章國內(nèi)外卡盤多刀車床分析比較72.1國內(nèi)外同類機(jī)床參數(shù)的分析比較72.2國內(nèi)外同類機(jī)床結(jié)構(gòu)及精度分析比較72.2.1結(jié)構(gòu)特點(diǎn)72.2.2精度比較8第3章機(jī)床的運(yùn)動(dòng)設(shè)計(jì)93.1極限轉(zhuǎn)速的確定93.2轉(zhuǎn)速數(shù)列公比的確定93.3主電機(jī)功率的確定103.4主傳動(dòng)系統(tǒng)的擬定11第4章主要零件的設(shè)計(jì)計(jì)算144.1三角帶的傳動(dòng)計(jì)算144.2摩擦片離合器的設(shè)計(jì)154.3傳動(dòng)軸設(shè)計(jì)164.3.1傳動(dòng)軸的直徑估計(jì)164.3.2軸彎曲剛度驗(yàn)算174.3.3軸上花鍵側(cè)擠壓力驗(yàn)算21www.yanziedu.c
