Muaj ob peb yam yuav tsum xav txog thaum xaiv cov bearings

 

"Ntau hom ntawmcov kabmobmuaj cov yam ntxwv sib txawv vim lawv cov qauv tsim sib txawv. Vim yog qhov sib txawv thiab qhov nyuaj ntawmkev coj uaQhov chaw teeb tsa thiab daim ntawv thov, tsis muaj tus qauv ruaj khov rau kev xaiv hom bearing. Thaum xaiv cov hom bearing kom hloov kho rau qhov chaw teeb tsa tshwj xeeb thiab cov xwm txheej ntawm lub tshuab tswj hwm tshwj xeeb, nws raug pom zoo kom xav txog cov ntsiab lus tseem ceeb hauv qab no.

 

Qhov Chaw Tso Cai: Hauv kev tsim kho tshuab, qhov loj ntawm lub ncej feem ntau yog txiav txim siab ua ntej, thiab tom qab ntawdkev coj uaraug xaiv raws li cov qhov ntev ntawd. Feem ntau, cov kabmob pob siv rau cov ncej me me; cov kabmob cylindrical roller, cov kabmob kheej kheej, thiab cov kabmob tapered roller (qee zaum cov kabmob pob kuj siv tau) siv rau cov ncej loj. Yog tias qhov chaw radial ntawm qhov chaw teeb tsa cov kabmob txwv, cov kabmob nrog qhov siab radial me dua yuav tsum tau siv. Piv txwv li suav nrog cov kabmob koob, qee cov kabmob pob sib sib zog nqus, cov kabmob pob sib cuag angular, cov kabmob cylindrical lossis cov kabmob kheej kheej, thiab cov kabmob nyias-walled. Yog tias qhov chaw axial ntawm qhov chaw teeb tsa cov kabmob txwv, cov kabmob nrog qhov dav me dua tuaj yeem siv tau.

 

**Kev Thauj Khoom:** Qhov loj ntawm kev thauj khoom feem ntau yog qhov txiav txim siab hauv kev xaivkev coj ualoj. Cov kabmob dov muaj peev xwm thauj khoom ntau dua li cov kabmob pob uas muaj tib qhov loj me sab nraud. Feem ntau, cov kabmob pob yog tsim rau cov khoom thauj me me lossis nruab nrab, thaum cov kabmob dov yog tsim rau cov khoom thauj hnyav.

 

Hom Thauj Khoom: Rau cov khoom thauj radial ntshiab,cov kabmob sib sib zog nqus or cylindrical roller bearingssiv tau. Rau cov khoom thauj axial ntshiab, cov kabmob pob thrust lossis cov kabmob cylindrical roller thrust siv tau. Thaum muaj ob qho tib si radial thiab axial loads (combined loads),angular tiv tauj pob bearings or cov kabmob tapered rau cov menyuamFeem ntau raug xaiv. Yog tias lub nra hnyav radial loj thiab lub nra hnyav axial me me, cov kabmob pob sib sib zog nqus thiab cov kabmob cylindrical nrog flanges ntawm ob lub nplhaib sab hauv thiab sab nraud tuaj yeem siv tau. Yog tias tseem muaj lub qhov loj lossis lub tsev deformation lossis kev teeb tsa tsis zoo, cov kabmob pob sib dhos lossis cov kabmob sib dhos tus kheej tuaj yeem siv tau. Yog tias lub nra hnyav axial loj thiab lub nra hnyav radial me me, cov kabmob pob sib dhos thrust angular tuaj yeem siv tau. Rau cov kabmob pob sib dhos plaub-taw tes, yog tias kev ua haujlwm sib dhos tus kheej kuj xav tau, cov kabmob sib dhos tus kheej tuaj yeem siv tau.

 

Ceev: Qhov ceev ua haujlwm ntawm lub dov bearing feem ntau nyob ntawm nws qhov kub ua haujlwm tso cai. Bearings nrog kev tsis kam sib txhuam tsawg thiab tsawg dua sab hauv cua sov tsim nyog rau kev siv ceev ceev. Thaum raug rau tsuas yog radial loads,cov kabmob sib sib zog nqusthiabcylindrical roller bearingstuaj yeem ua tiav qhov ceev dua. Rau cov khoom thauj ua ke, ibngular tiv tauj pob bearingszoo dua. Cov kabmob pob angular contact uas muaj kev tsim tshwj xeeb tuaj yeem ua tiav qhov ceev siab heev. Qhov ceev ntawm txhua lub thrust bearings qis dua li cov ntawm radial bearings.

 

Kev Ntsuas Qhov Tseeb: Rau feem ntau cov tshuab, cov kabmob uas muaj kev kam rau siab ntawm qib 0 txaus kom ua tau raws li qhov yuav tsum tau ua ntawm lub tshuab tswj hwm. Txawm li cas los xij, thaum muaj cov kev cai nruj rau kev ntsuas qhov tseeb ntawm lub ncej, xws li hauv cov cuab yeej tshuab spindles, cov tshuab precision, thiab cov cuab yeej, qib siab dua ntawm cov kabmob sib sib zog nqus, cov kabmob sib cuag pob, cov kabmob tapered roller,cylindrical roller bearings,thiab yuav tsum xaiv cov angular contact pob bearings.

 

Kev Rigidity: Qhov rigidity ntawm lub dov bearing yog txiav txim siab los ntawm qhov ntau ntawm elastic deformation uas tshwm sim thaum nws dais lub nra hnyav. Feem ntau, qhov deformation no me heev thiab tuaj yeem tsis quav ntsej. Txawm li cas los xij, hauv qee lub tshuab, xws li lub tshuab cuab yeej spindle systems, qhov static thiab dynamic stiffness ntawm lub bearing muaj kev cuam tshuam loj heev rau cov yam ntxwv ntawm lub system. Feem ntau hais lus, cov roller bearings muaj rigidity siab dua li cov pob bearings. Ntau yam bearings tuaj yeem muaj lawv cov rigidity txhim kho rau ntau qib los ntawm kev ua ntej nruj lawv.

 

Suab nrov thiab kev co: Cov bearings lawv tus kheej feem ntau muaj suab nrov thiab kev co qis. Txawm li cas los xij, rau cov tshuab nrog cov kev cai tshwj xeeb rau suab nrov thiab kev ua haujlwm du, xws li cov cav me me thiab nruab nrab, cov khoom siv hauv chaw ua haujlwm, cov khoom siv hauv tsev, thiab cov twj paj nruag, cov bearings suab nrov qis feem ntau raug xaiv.

 

Kev Txav Mus Los Axial: Qhov kev teeb tsa feem ntau ntawm cov kabmob yog kev teeb tsa ib lub kabmob ruaj khov (nyob rau hauv qhov chaw axially) ntawm ib kawg ntawm lub qag thiab ib lub kabmob ntab uas txav tau dawb (nyob rau hauv qhov chaw txav tau) ntawm qhov kawg kom tiv thaiv kev ntes vim yog thermal nthuav dav thiab kev sib cog lus. Cov kabmob ntab uas siv ntau yog cov kabmob cylindrical roller uas tsis muaj flanges ntawm lub nplhaib sab hauv lossis sab nraud. Hauv qhov no, kev sib haum xeeb tuaj yeem siv ntawm lub nplhaib sab hauv thiab lub qag, lossis ntawm lub nplhaib sab nraud thiab lub qhov tsev. Qee zaum, tsis sib caiscov kabmob sib sib zog nquslossis cov kabmob uas sib dhos ua ke tus kheej tuaj yeem siv ua cov kabmob ntab, tab sis thaum lub sijhawm teeb tsa, yuav tsum xaiv qhov sib txawv ntawm lub nplhaib sab hauv thiab lub qhov, lossis ntawm lub nplhaib sab nraud thiab lub qhov tsev, kom ntseeg tau tias muaj kev ywj pheej txaus rau lub nplhaib sab hauv lossis sab nraud.

 

Kev sib txhuam Torque

Cov kabmob pob muaj qhov tsis kam sib txhuam qis dua li cov kabmob menyuam. Hauv qab cov khoom siv radial ntshiab, cov kabmob sib cuag radial muaj qhov tsis kam sib txhuam qis dua; hauv qab cov khoom siv axial ntshiab, cov kabmob sib cuag axial muaj qhov tsis kam sib txhuam qis dua; hauv qab cov khoom sib xyaw ua ke,angular tiv tauj bearingsnrog rau cov ces kaum sib cuag ze rau lub kaum sab xis muaj qhov tsis kam sib txhuam qis tshaj plaws. Hauv cov cuab yeej thiab cov tshuab uas xav tau qhov sib txhuam qis, cov kabmob pob lossiscylindrical roller bearingsyog qhov tsim nyog dua. Ntxiv mus, cov kabmob uas tsis muaj kev sib txhuam tsawg yuav tsum tsis txhob sib cuag nrog cov foob, thiab kev siv lubrication nrog dej, roj-cua lubrication, lossis lwm txoj kev siv lubrication uas txo kev sib txhuam raug pom zoo.

 

Kev Teeb tsa thiab Kev Tshem Tawm

Cov kabmobnrog cov cylindrical bores siv rau hauv cov tshuab nrog kev teeb tsa thiab tshem tawm ntau zaus. Sib cais tauangular tiv tauj pob bearings, cov kabmob tapered rau cov menyuam, sib cais taucylindrical roller bearings, cov kabmob koob rau cov menyuam, thiab cov kabmob thawb yuav tsum tau nyiam dua. Cov kabmob nrog cov qhov tapered tuaj yeem raug teeb tsa rau ntawm cov ntawv xov xwm lossis, nrog kev pab ntawm cov tes tsho adapter lossis cov tes tsho rho tawm, rau ntawm cov ntawv xov xwm cylindrical, ua rau kev teeb tsa thiab kev tshem tawm yooj yim heev.
