1. Qhov yuav tsum tau muaj rau precision bearings ntawm qhov sib txuam
Txij li qhov tseeb ntawm qhov tseeb ntawm nws tus kheej yog nyob rau hauv 1 μm, nws yuav tsum muaj qhov siab qhov tseeb thiab cov duab raug nrog nws cov khoom sib xws (shaft, bearing seat, end cover, retaining ring, etc.), tshwj xeeb tshaj yog qhov tseeb ntawm mating. nto yuav tsum tau tswj nyob rau tib theem li cov kabmob Qhov no yog ib qho tseem ceeb thiab feem ntau yooj yim overlooked.
Nws kuj yuav tsum raug sau tseg tias yog tias qhov sib txuam ntawm cov kabmob precision tsis ua raws li cov kev cai saum toj no, cov kabmob precision feem ntau yuav muaj qhov yuam kev ntau zaus ntau dua li cov kabmob qub tom qab kev teeb tsa, lossis ntau dua 10 npaug ntawm qhov yuam kev, thiab nws. tsis yog precision bearing kiag li.Yog vim li cas yog tias lub tshuab sib txuam Qhov kev ua yuam kev ntawm cov khoom feem ntau tsis yog tsuas yog superimposed ntawm qhov yuam kev ntawm cov kabmob, tab sis ntxiv tom qab tau nthuav dav los ntawm ntau qhov sib txawv.
2. Haum ntawm precision bearings
Txhawm rau kom ntseeg tau tias cov kabmob tsis tsim ntau deformation tom qab kev teeb tsa, nws yuav tsum tau ua:
(1) Lub roundness ntawm lub ncej thiab lub qhov rooj thiab lub verticality ntawm lub xub pwg nyom yuav tsum tau raws li qhov sib thooj precision ntawm cov kabmob.
(2) Nws yog ib qho tsim nyog los xam qhov cuam tshuam ntawm lub rotating ferrule thiab qhov tsim nyog haum ntawm qhov ruaj khov ferrule.
Qhov cuam tshuam ntawm rotating ferrule yuav tsum tsawg li tsawg tau.Ntev npaum li qhov cuam tshuam ntawm thermal expansion ntawm qhov ua haujlwm kub thiab qhov cuam tshuam ntawm centrifugal quab yuam ntawm qhov siab tshaj plaws tau ua kom ntseeg tau, nws yuav tsis ua rau nkag los yog zawv zawg ntawm qhov ntom ntom ntom ntom.Raws li qhov loj ntawm kev ua haujlwm load thiab qhov loj ntawm cov kabmob, lub nplhaib ruaj khov xaiv qhov kev tshem tawm me me heev los yog cuam tshuam haum.Kev xoob dhau los yog nruj dhau tsis yog qhov tsim nyog rau kev tswj xyuas qhov qub thiab raug.
(3) Yog tias cov kabmob ua haujlwm nyob rau hauv kev kub ceev thiab kev ua haujlwm kub siab, kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov haum ntawm lub nplhaib tig kom tsis txhob xoob dhau los tiv thaiv eccentric kev co, thiab qhov haum ntawm lub nplhaib ruaj ruaj kom tsis txhob muaj qhov khoob. los ntawm qhov tshwm sim.Deforms nyob rau hauv load thiab excites vibrations.
(4) Cov xwm txheej rau kev siv qhov cuam tshuam me me haum rau lub nplhaib ruaj khov yog tias ob sab ntawm qhov sib txuam nto muaj qhov raug siab thiab me me roughness, txwv tsis pub nws yuav ua rau kev teeb tsa nyuaj thiab disassembly nyuaj dua.Tsis tas li ntawd, qhov cuam tshuam ntawm thermal elongation ntawm spindle yuav tsum tau xav txog.
(5) Lub ntsiab ncej siv ib khub ntawm ob-txuas angular hu rau pob bearings feem ntau muaj lub teeb load.Yog tias qhov kev cuam tshuam haum loj dhau lawm, lub hauv paus axial preload yuav loj dua, ua rau muaj kev cuam tshuam tsis zoo.Lub ntsiab ncej siv ob-kab luv cylindrical cov menyuam bearings thiab lub ntsiab ncej ntawm tapered menyuam bearings muaj kuj loj loads, yog li qhov haum cuam tshuam kuj tseem loj.
3. Cov txheej txheem ntawm kev txhim kho qhov kev sib tw tiag tiag
Txhawm rau txhim kho qhov tseeb qhov tseeb ntawm kev teeb tsa ntawm cov kabmob, nws yog qhov yuav tsum tau siv cov txheej txheem ntsuas thiab ntsuas cov cuab yeej uas tsis deform cov kabmob kom ua tiav qhov tseeb qhov ntsuas ntawm qhov sib txuam ntawm qhov ntev ntawm lub qhov thiab lub voj voog sab nraud ntawm cov kabmob, thiab kev ntsuas ntawm lub puab txoj kab uas hla thiab txheej sab nraud tuaj yeem nqa tau tag nrho cov khoom raug ntsuas, thiab cov ntaub ntawv ntsuas tau raug txheeb xyuas, raws li qhov, qhov ntev ntawm cov kabmob installation qhov chaw ntawm lub ncej thiab lub qhov rooj yog qhov sib npaug.Thaum ntsuas qhov sib thooj thiab cov duab geometric ntawm cov ncej thiab lub qhov rooj, nws yuav tsum tau nqa tawm nyob rau hauv qhov kub thiab txias ib yam li thaum ntsuas cov kabmob.
Txhawm rau kom ntseeg tau tias muaj txiaj ntsig zoo sib xws, qhov roughness ntawm cov ncej thiab lub qhov hauv vaj huam sib luag sib piv cov kabmob nto yuav tsum me me li sai tau.
Thaum ua cov kev ntsuas saum toj no, ob pawg ntawm cov cim uas tuaj yeem qhia qhov kev taw qhia ntawm qhov sib txawv siab tshaj plaws yuav tsum tau ua rau ntawm lub voj voog sab nrauv thiab sab hauv lub qhov ntawm cov kabmob, thiab ntawm qhov sib thooj ntawm cov ncej thiab lub qhov rooj, ntawm ob sab kaw. mus rau lub rooj sib txoos chamfer, yog li ntawd nyob rau hauv lub rooj sib txoos tiag tiag, qhov siab tshaj plaws sib txawv ntawm ob lub koom haum sib koom ua ke nyob rau hauv tib qho kev taw qhia, yog li ntawd tom qab sib dhos, qhov sib txawv ntawm ob tog tuaj yeem cuam tshuam ib nrab.
Lub hom phiaj ntawm kev ua ob pawg ntawm kev taw qhia cov cim yog tias cov nyiaj them rau qhov sib txawv tuaj yeem suav tau ua tiav, kom qhov kev sib hloov qhov tseeb ntawm ob qhov kawg ntawm kev txhawb nqa tau zoo dua qub, thiab coaxiality yuam kev ntawm lub rooj zaum qhov nruab nrab ntawm ob qhov kev txhawb nqa thiab cov ntawv xov xwm ncej ntawm ob qhov kawg yog ib feem tau.tshem tawm.Kev ua raws li qhov kev ntsuas kev ua kom muaj zog ntawm qhov chaw mating, xws li sandblasting, siv lub qhov ntsaws ruaj ruaj nrog ib txoj kab uas hla me ntsis los ntsaws lub qhov hauv ib zaug, thiab lwm yam, yog qhov tsim nyog rau kev txhim kho qhov tseeb mating.
