Kev xaiv ntawm bearing clearance thiab configuration yog ib qho tseem ceeb heev ib feem ntawm lub cev muaj zog tsim, thiab cov kev xaiv xaiv yam tsis paub qhov kev ua tau zoo ntawm bearing yog zoo li yuav ua tsis tau tejyam tsim.Cov kev ua haujlwm sib txawv muaj qhov sib txawv rau cov bearings.
Lub hom phiaj ntawm kev coj tus kheej lubrication yog cais cov dov cov khoom thiab cov dov nto nrog cov roj nyias zaj duab xis, thiab tsim cov roj lubricating roj zaj duab xis rau ntawm qhov chaw dov thaum ua haujlwm, yog li txo qhov kev sib txhuam sab hauv ntawm cov kabmob thiab hnav ntawm txhua lub caij, tiv thaiv sintering.Lub lubrication zoo yog qhov tsim nyog rau cov kabmob ua haujlwm.Kev soj ntsuam ntawm qhov ua rau muaj kev puas tsuaj ntawm cov kabmob qhia tau hais tias txog 40% ntawm cov kabmob puas muaj feem cuam tshuam rau lubrication tsis zoo.Cov txheej txheem lubrication tau muab faib ua roj lubrication thiab roj lubrication.
Roj lubrication muaj qhov zoo dua uas nws tsis tas yuav tsum tau ntxiv rau lub sijhawm ntev tom qab sau cov roj ib zaug, thiab cov qauv sealing yog qhov yooj yim, yog li nws tau siv dav.Roj yog ib tug semi-solid lubricant ua los ntawm lubricating roj raws li lub hauv paus roj thiab tov nrog ib tug khoom thickener nrog muaj zog lipophilicity.Txhawm rau txhim kho qee tus yam ntxwv, ntau yam tshuaj ntxiv kuj ntxiv.Roj lubrication, feem ntau suav nrog cov roj lubrication, dav hlau lubrication, thiab roj pos huab lubrication.Cov roj lubricating rau cov kabmob feem ntau yog ua raws li cov roj ntxhia ua kom zoo nrog cov oxidation zoo thiab xeb tsis kam, thiab cov roj ua kom muaj zog, tab sis ntau cov roj hluavtaws feem ntau siv.
Cov kabmob kev sib hloov ntawm qhov sib hloov ntawm lub cev muaj zog (xws li lub ntsiab ncej) feem ntau yuav tsum tau txais kev txhawb nqa los ntawm ob pawg ntawm cov kabmob, thiab cov rotating ib feem yog positioned radially thiab axially txheeb ze rau ib feem ntawm lub tshuab (xws li cov kabmob. rooj).Raws li qhov kev thov, xws li kev thauj khoom, qhov yuav tsum tau ua kom raug thiab cov nqi yuav tsum tau muaj, cov txheej txheem kev coj tus kheej tuaj yeem suav nrog cov hauv qab no: Cov kabmob kev npaj nrog kev ruaj khov thiab ntab kawg Pre-kho kabmob kev npaj (tso rau ntawm ob qho kawg) "Floating" fine bearing configuration ( ob qhov kawg ntab)
Cov kabmob ruaj khov kawg yog siv rau kev txhawb nqa radial ntawm ib qho kawg ntawm tus ncej thiab rau qhov chaw axial hauv ob qho kev qhia tib lub sijhawm.Yog li ntawd, qhov ruaj khov kawg bearing yuav tsum tau kho ntawm lub ncej thiab cov kabmob vaj tse nyob rau tib lub sijhawm.Bearings tsim nyog rau kev siv ntawm qhov kawg yog cov kabmob radial uas tuaj yeem tiv thaiv kev sib koom ua ke, xws li sib sib zog nqus groove pob bearings, ob kab los yog ua ke ib kab angular hu rau pob bearings, tus kheej-aligning pob bearings, kheej kheej thiab cov menyuam bearings los yog sib tw tapered menyuam bearings. .sub bearing.Radial bearings uas tsuas muaj peev xwm dais ntshiab radial loads, xws li khoom cylindrical roller bearings nrog ib lub nplhaib tsis muaj tav, thiab lwm yam bearings (xws li sib sib zog nqus groove pob bearings, plaub-point contact pob bearings lossis bidirectional thrust bearings) thiab lwm yam.) kuj tseem siv rau qhov kawg ruaj thaum siv hauv pab pawg.Nyob rau hauv no configuration, lwm bearing tsuas yog siv rau axial positioning nyob rau hauv ob txoj kev, thiab ib tug tej yam degree ntawm radial kev ywj pheej yuav tsum tau sab laug nyob rau hauv lub bearing lub rooj (piv txwv li, clearance yuav tsum tau tshwj tseg nrog lub rooj zaum bearing).
Lub floating kawg bearing tsuas yog siv rau kev txhawb nqa radial ntawm lwm qhov kawg ntawm cov ncej, thiab cov ncej yuav tsum tau tso cai kom muaj qee qhov kev hloov axial, thiaj li yuav tsis muaj kev sib koom tes ntawm cov kabmob.Piv txwv li, thaum cov kabmob nthuav dav vim yog cua sov, qhov kev hloov pauv ntawm axial tuaj yeem ua tau qee yam ntawm cov kabmob yog siv sab hauv.Axial tshem tawm tuaj yeem tshwm sim ntawm ib qho ntawm cov kabmob rings thiab ib feem uas lawv txuas nrog, nyiam dua ntawm lub nplhaib sab nraud thiab lub bore.
