Muaj 6 yam yuav tsum xav txog thaum xaiv cov bearings rau cov khoom siv tub yees
Txhua hom kev dov bearings muaj cov yam ntxwv sib txawv thiab tsim nyog rau kev siv sib txawv ntawm ntau yam tshuab. Nyob rau hauv ib txwm muaj xwm txheej,cov bearings thrust thiab angular contact bearingsraug xaiv thaum nqa cov khoom hnyav;
Cov kabmob pobfeem ntau yog siv rau cov ntawv thov ceev ceev, thiab cov menyuam bearings yog siv rau cov khoom hnyav radial.
1. Qhov chaw thiab qhov chaw ntawm cov tshuab uas siv los ntawmkev coj ua
Hauv kev tsim kho tshuab, qhov loj ntawm lub qag feem ntau yog txiav txim siab ua ntej, thiab tom qab ntawd cov kabmob dov raug xaiv raws li qhov loj ntawm lub qag. Cov kabmob pob feem ntau yog siv rau cov qag me me thiab cov kabmob menyuam rau cov qag loj. Txawm li cas los xij, thaum cov kabmob raug txwv hauv qhov kev taw qhia ntawm lub tshuab,koob txhaj tshuaj bearings, pob lossis cov menyuam bearings ntawm cov koob ntxiv lub teeb thiab ultra-lub teeb raug xaiv; Thaum qhov chaw axial ntawm cov kabmob hauv lub tshuab raug txwv, cov koob nqaim lossis cov koob nqaim ntxiv ntawm cov pob lossis cov menyuam bearings muaj.
2. Qhov loj, kev coj thiab qhov xwm txheej ntawm lub nra hnyav ntawm tus kabmob
Qhov hnyav yog qhov tseem ceeb tshaj plaws hauv kev xaiv cov bearings. Cov bearings roller siv los tiv taus cov khoom hnyav dua, cov bearings pob siv los tiv taus cov khoom me me lossis nruab nrab, thiab cov bearings ua los ntawm cov hlau carburized lossis bainite quenched yog tsim los tiv taus kev poob siab thiab kev co.
Hais txog qhov kev taw qhia ntawm kev ua haujlwm ntawm lub nra hnyav, thaum nqa cov khoom thauj radial ntshiab, cov kabmob pob sib sib zog nqus, cov kabmob cylindrical roller lossis cov kabmob koob rau cov menyuam tuaj yeem xaiv tau. Thaum nqa cov khoom thauj axial me me, cov kabmob thrust tuaj yeem xaiv tau; cov kabmob thrust roller muaj rau cov khoom thauj axial loj. Thaum cov kabmob raug kev sib xyaw ua ke ntawm radial thiab axial, cov kabmob pob sib cuag angular lossis cov kabmob tapered feem ntau siv.
3.Kev ua tau zoo ntawm tus kheej ntawm cov kabmob
Thaum txoj kab nruab nrab ntawm tus ncej txawv ntawm txoj kab nruab nrab ntawm lub tsev bearing, muaj qhov yuam kev angular, lossis vim tias qhov sib nrug ntawm ob lub txhawb nqa ntawm tus ncej loj thiab qhov rigidity ntawm tus ncej me me, nws yooj yim khoov lossis qaij raws li lub zog, lub pob kheej kheej lossis tus kheej ...
Qhov zoo ntawm kev ua tau zoo ntawm kev coj tus kheej yog cuam tshuam nrog qhov sib txawv axial uas nws tso cai, thiab qhov loj dua tus nqi ntawm ntau yam axial, qhov zoo dua qhov kev ua tau zoo ntawm kev coj tus kheej.
4. Kev ruaj khov ntawm cov kabmob
Qhov kev tawv ntawm cov kabmob yog hais txog qhov ntau ntawm lub zog uas xav tau rau cov kabmob los tsim cov qauv deformation. Qhov kev hloov pauv elastic ntawm cov kabmob dov yog me me heev, thiab nws tsis tas yuav xav txog nws hauv feem ntau cov tshuab, tab sis hauv qee cov tshuab, xws li cov cuab yeej tshuab spindles, qhov kev tawv ntawm cov kabmob yog qhov tseem ceeb, thiab feem ntau yuav tsum xaiv cov kabmob cylindrical thiab tapered roller. Vim tias ob hom kabmob no nyob rau hauv qhov sib cuag nrog txoj kev sib tw thaum lawv nyob hauv qab kev thauj khoom, qhov kev tawv tsis zoo.
Tsis tas li ntawd xwb, txhua hom bearings kuj tseem tuaj yeem raug preloaded kom ua tiav lub hom phiaj ntawm kev ua kom lub zog ntawm kev txhawb nqa. Piv txwv li,angular tiv tauj pob bearingsthiab tapered roller bearings, txhawm rau tiv thaiv kev co ntawm lub ncej thiab ua kom lub zog ntawm kev txhawb nqa nce ntxiv, qee lub zog axial feem ntau siv ua ntej thaum lub sijhawm teeb tsa kom ua rau lawv sib zog. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov ntawm no tias qhov ntau ntawm preload yuav tsum tsis txhob loj dhau. Thaum nws loj dhau, kev sib txhuam ntawm cov kabmob yuav nce ntxiv, qhov kub nce ntxiv yuav nce ntxiv, thiab lub neej ua haujlwm ntawm cov kabmob yuav raug cuam tshuam.
5. Qhov ceev ntawm kev sib hloov ntawm cov kabmob
Txhua tus qauv bearing muaj nws tus kheej qhov ceev txwv, uas yog txiav txim siab los ntawm cov yam ntxwv ntawm lub cev xws li qhov loj me, hom thiab cov qauv, qhov ceev txwv yog hais txog qhov ceev ua haujlwm siab tshaj plaws ntawm bearing (feem ntau r / min), dhau qhov txwv no yuav ua rau qhov kub ntawm bearing nce, cov roj nplua nyeem kom qhuav, thiab txawm tias ua rau bearing daig. Qhov ceev uas xav tau rau daim ntawv thov pab txiav txim siab seb hom bearing twg yuav siv. Feem ntau cov chaw tsim khoom bearing muab qhov ceev kawg ntawm lawv cov khoom hauv lawv cov ntawv teev khoom, thiab kev xyaum tau ua pov thawj tias nws zoo dua los ua haujlwm hauv lub xeev qis dua 90% ntawm qhov ceev txwv.
Feem ntau hais lus, thaum lub sijhawm ua haujlwm ntawm qhov ceev dua, nws yog qhov zoo dua los xaiv cov kabmob sib sib zog nqus, cov kabmob sib cuag angular, thiab cov kabmob cylindrical roller; Ntawm qhov ceev qis dua, cov kabmob tapered roller yog xaiv tau. Qhov ceev kawg ntawm cov kabmob tapered roller feem ntau yog li 65% ntawm qhov ceev ntawm cov kabmob sib sib zog nqus, 70% ntawm cov kabmob cylindrical roller, thiab 60% ntawm cov kabmob sib cuag angular. Cov kabmob thrust muaj qhov ceev txwv qis thiab tsuas yog siv tau ntawm qhov ceev qis dua.
6. Nws yooj yim rau kev teeb tsa thiab kev sib cais ntawm cov bearings
Thaum xaiv hom kabmob, nws tseem ceeb heev uas yuav tsum xav txog seb lub kabmob puas yooj yim rau kev teeb tsa thiab rhuav tshem, tshwj xeeb tshaj yog rau kev teeb tsa thiab rhuav tshem cov kabmob loj thiab loj heev. Cov kabmob sib txuas dav dav, cov kabmob tapered roller, cylindrical roller bearings thiab koob roller bearings nrog cov nplhaib sab nraud sib cais tau yooj yim rau kev teeb tsa thiab rhuav tshem, thiab lawv cov nplhaib sab hauv thiab sab nraud tuaj yeem ntsia tau rau ntawm tus ncej lossis hauv lub qhov tsev. Tsis tas li ntawd, cov kabmob kheej kheej nrog lub qhov tapered thiab lub tes tsho adapter, ob kab cylindrical roller bearings thiab lub pob kheej kheej yooj yim rau kev teeb tsa thiab rhuav tshem.
