Daim Ntawv Qhia Xaiv Cov Ntawv Qhia


Cov hom, cov qauv, thiab ntau thiab tsawg ntawm cov dov dov muaj ntau yam. Txhawm rau ua kom cov cuab yeej siv cav ua si qhov kev ua tiav, nws yog qhov tseem ceeb heev rau xaiv cov kabmob haum tshaj plaws

Txhawm rau xaiv cov kabmob, ntau yam yuav tsum tau ntsuas. Cov kab ke dav dav yog raws li hauv qab no:

(1) Nkag siab txog cov haujlwm ua haujlwm ntawm cov khoom siv kho tshuab thiab cov kabmob, thiab lwm yam.

(2) Cov kev ntshiab ua kom zoo ntawm cov kabmob

(3) Xaiv hom kabmob

(4) Xaiv cov kabmob kev teeb tsa

(5) Xaiv cov kabmob loj

(6) Xaiv cov kabmob tshwj xeeb

(7) Kev teeb tsa ntawm xaiv cov kabmob


Qhov chaw nyob ntawm cov kabmob, kev ua haujlwm ntawm kev ua haujlwm, thiab cov xwm txheej ib puag ncig yog qhov tsim nyog rau kev xaiv cov kabmob haum. Rau qhov no, nws yog qhov tsim nyog kom tau txais cov ntaub ntawv thiab ntaub ntawv hauv qab no:

(1) Muaj nuj nqi thiab cov qauv ntawm cov tshuab ntaus ntawv

(2) Qhov twg siv rau kev coj tus kabmob

(3) Cov kabmob hnyav (qhov loj, kev taw qhia)

(4) Kev sib hloov ceev

(5) Kev co thiab poob siab

(6) Cov kabmob siab kub (qhov kub thiab txias, qhov kub nce siab)

(7) Ib puag ncig huab cua (xeb, huv, lubricating)



Yuav ua li cas xaiv hom kabmob rau koj lub tshuab?


Thaum xaiv hom kabmob, nws yog ib qho tseem ceeb kom nkag siab txog kev ua haujlwm ntawm kev coj tus kabmob. Cov ntaub ntawv hauv qab no qhia cov kev tshuaj ntsuam tseem ceeb:

Kev Tsom Xam KhoomTxoj Kev Xaiv
1) Cov kabmob chaw teeb tsaCov kabmob uas tuaj yeem ua tus tso rau hauv qhov chaw nruab cov kabmob.

Raws li daim hlau tau tsim nrog kev ua kom pom tseeb ntawm txoj kev nruj thiab lub zog ntawm tus ncej, lub puab tsaig yog lub puab diam ntawm cov kabmob, uas feem ntau txiav txim siab ua ntej.

Txawm li cas los xij, dov bearings muaj ntau hom loj me thiab hom, los ntawm qhov uas peb yuav tsum xaiv cov kabmob haum tsim nyog.

2) Thauj khoomCov hauv qab no yog qhov yuav tsum tau txiav txim siab:

Qhov loj me ntawm lub nra;

Radial load, axial load; los ntawm ib qho kev taw qhia lossis ob qho kev taw qhia;

Qhov ntsuas ntawm kev vibration lossis poob siab.

Feem ntau hais lus, tusradial load muaj peev xwmntawm cov kabmob nrog tib txoj kab uas hla tib lub nce hauv qhov kev txiav txim hauv qab no:

sib sib zog nqus groove pob bearings

GG lt;angular cuag pob bearingsGG lt;cylindrical roller bearings

GG lt;tapered cov menyuam kabmob

GG lt;kheej kheej cov menyuam bearings

3) Kev sib hloov ceevQhov txwv tsis pub dhau ntawm cov kabmob tsis yog tsuas yog coj los ntawm cov kabmob hom tab sis tseem txwv rau cov kabmob loj, hom tawb, qib qhov raug, qhov xwm txheej, thiab txheej txheem lubrication, thiab lwm yam. Yog li ntawd, cov xwm txheej no yuav tsum tau txiav txim siab thaum xaiv.

Cov kabmob nram qab no feem ntau yog siv raukev kub ceev kev sib hloov:

Groove sib sib zog nqus pob bearings,

angular cuag pob bearings, cylindrical roller bearings

4) Kev Muaj Peev Xwm Hloov
Rautshuab ntxaiv ntxaivuas yuav tsum tau muaj qhov tseeb ua haujlwm nrawm, nrog rau cov tshuab ua haujlwm uas yuav tsum tau muaj qhov siab nrawm dua li cov tshuab turbochargers, cov kabmob muaj peev xwm nyob hauv Qib 5, Qeb 4, thiab Qeb 2 yuav tsum tau siv.Cov kabmob nram qab no feem ntau siv rau hauv cov ntaub ntawv thov raug:

Groove sib sib zog nqus pob bearings,

angular cuag pob bearings, cylindrical roller bearings

5) RigidityThaum cov kabmob tau nyob hauv qhov thauj, feem sib tiv tauj ntawm cov ntxuag thiab cov kev sib tw yuav raug hloov elastically.GG quot; High rigidity"txhais tau hais tias qhov nyiaj ntawm deformation ntawm qhov hluav taws xob tsis xwm yeem no yog qhov me me.Hauv seem xws li lub plhaw loj ntawm lub tshuab cuab yeej thiab cov cuab yeej txo qis kawg ntawm lub tsheb, thaum nce qhov txhav ntawm tus ncej, lub nruj ntawm cov kabmob yuav tsum tau txhim kho.

Cov menyuam bearings tau qis dua kev ua haujlwm tsis tau qis dua lub pob bearings.

Thauj cov kabmob (tsis pom zoo)tuaj yeem nce rigidity. Hom no haum rauangular cuag pob bearingsthiabtapered cov menyuam kabmob.

6) Tus kheej txheeb zoo ntawm lub nplhaib sab hauv thiab lub nplhaib sab nraudYog tias tus txheeb ze qaij nruab nrab ntawm lub nplhaib sab hauv thiab lub nplhaib sab nraud loj dhau, cov kabmob yuav raug puas vim kev thauj khoom sab hauv. Yog li, peb yuav tsum xaiv cov kabmob hom uas tuaj yeem tiv taus qhov qaij no.Tso cai qaij kaum (los yog tus kheej-teeb lub kaum) nce nyob rau hauv cov kev txiav txim hauv qab no:

Cylindrical roller bearings,

tapered cov menyuam kabmob,

angular cuag pob bearings,

kheej kheej cov menyuam (pob) bearings

7) Kev sib dhos thiab rho tawmZaus thiab cov qauv ntawm kev sib dhos thiab disassembly rau kev kuaj xyuas tsis tu ncuaThaum sib dhos thiab kev cais tawm ntau zaus, nws yooj yim dua rau sivcylindrical roller bearingsnrog sib cais sib cais sab hauv thiab sab nrauv, koob rau cov menyuam, thiabtapered cov menyuam kabmob.

Tapered bore spherical pob bearing thiabkheej kheej cov menyuam bearingstuaj yeem yooj yim sib sau ua ke thiab rhuav tshem los ntawm kev siv khawm ris tsho lossis rho tawm tes tsho.



Yuav ua li cas xaiv cov kabmob tau tsim rau koj lub tshuab?


Cov hom tshuab yog txawv, qhov kev pabcuam ntawm cov kabmob yuav txawv, thiab qhov ua tau raws li kev ua haujlwm kuj sib txawv. Feem ntau hais lus, muaj ntau tshaj ob lub kabmob uas yuav siv rau ntawm tus ua haujlwm.

Txhawm rau ua kom yooj yim axial positioning, feem ntau ntawm cov kabmob tau siv los ua kev ruaj ntseg kawg, thiab qhov seem yog siv cov nplais-kawg bearings. Cov lus hauv qab no qhia cov kev xaiv uas ruaj ruaj thiab ntab ntaws cov kabmob cov qauv.

Kev Tshawb XyuasSiv tau cov kabmob hom
Tsau-Xoom Kab Mob

Bearings siv rau kev muab tso rau axial thiab kho:

Xaiv cov kabmob uas tuaj yeem lav cov thauj khoom radial thiab axial tib lub sijhawm.

Txhawm rau ua kom lub bidirectional axial load, nws yog ib qho tsim nyog yuav tsum txiav txim siab lub zog sib haum raws li cov axial load thaum lub sijhawm teeb tsa.
