Bearings, uas yog ib qho tseem ceeb thiab tseem ceeb ntawm cov khoom siv kho tshuab, ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa rotating ncej.Raws li qhov sib txawv ntawm kev sib txhuam ntawm cov kabmob, cov kabmob tau muab faib ua cov kabmob sib txhuam (xws li dov bearing) thiab zawv zawg kev sib txhuam kabmob (xws li zawv zawg bearing).Ob hom bearings muaj lawv tus kheej cov yam ntxwv hauv cov qauv thiab qhov zoo thiab qhov tsis zoo hauv kev ua haujlwm.

1. Kev sib piv ntawm dov bearings thiab zawv zawg bearings

1. Kev sib piv ntawm cov qauv thiab kev txav mus los

Qhov pom tseeb tshaj plaws ntawm qhov sib txawv ntawm dov bearings thiab cov kabmob dawb yog qhov muaj lossis tsis muaj cov ntsiab lus dov.

(1) Rolling bearings muaj dov cov ntsiab lus (pob, cylindrical rollers, tapered rollers, koob rollers), uas tig los txhawb lub rotating ncej, yog li qhov kev sib cuag yog ib qho taw tes, cov ntsiab lus dov ntau dua, cov ntsiab lus sib cuag ntau dua.

(2) Cov zawv zawg kabmob tsis muaj cov khoom dov, thiab cov ncej tig tau txais kev txhawb nqa los ntawm qhov chaw du, yog li qhov kev sib cuag yog qhov chaw. Qhov sib txawv ntawm cov qauv ntawm ob qho kev txiav txim siab tias qhov kev txav txav ntawm cov kabmob dov yog dov, thiab kev txav ntawm cov kabmob zawv zawg yog zawv zawg, yog li qhov xwm txheej kev sib txhuam sib txawv kiag li.

2. Kev sib piv ntawm lub peev xwm nqa

Feem ntau hais lus, vim yog qhov loj ntawm qhov hnyav ntawm qhov zawv zawg bearings, lub peev xwm ntawm zawv zawg bearings feem ntau siab dua li ntawm cov kabmob dov, thiab lub peev xwm ntawm dov bearings los tiv thaiv kev cuam tshuam cov loads tsis siab, tab sis tag nrho cov kua lubricated bearings. tuaj yeem tiv taus ntau qhov kev poob siab loj.Thaum qhov kev sib hloov ceev yog siab, lub zog centrifugal ntawm cov ntsiab lus dov hauv cov kabmob dov nce, thiab nws lub peev xwm nqa yuav tsum raug txo qis (lub suab nrov yog tshwm sim ntawm kev kub ceev).Rau hydrodynamic zawv zawg bearings, lub peev xwm nqa tau nce raws li qhov kev sib hloov ceev nce.

3. Kev sib piv ntawm kev sib txhuam coefficient thiab pib frictional kuj

Raws li kev ua haujlwm ib txwm muaj, kev sib txhuam coefficient ntawm dov bearings yog qis dua li ntawm zawv zawg bearings, thiab tus nqi yog qhov ruaj khov.Lub lubrication ntawm zawv zawg bearings tau yooj yim cuam tshuam los ntawm lwm yam xws li kev sib hloov ceev thiab kev co, thiab kev sib txhuam coefficient sib txawv.

Thaum pib, txij li cov zawv zawg kabmob tseem tsis tau tsim cov roj yeeb yaj kiab ruaj khov, qhov kev tiv thaiv yog ntau dua li ntawm cov kabmob dov, tab sis qhov kev sib txhuam pib ua haujlwm thiab kev sib txhuam coefficient ntawm hydrostatic zawv zawg bearings yog tsawg heev.

4. Kev sib piv ntawm kev ua haujlwm ceev

Vim qhov kev txwv ntawm lub zog centrifugal ntawm cov khoom dov thiab qhov kub thiab txias ntawm cov kabmob, cov kabmob dov tsis tuaj yeem tig siab dhau, thiab feem ntau haum rau nruab nrab thiab qis ceev ua haujlwm.Vim lub cua sov thiab hnav ntawm cov kabmob, kev ua haujlwm ceev ntawm cov kua tsis tiav lubricated bearing yuav tsum tsis txhob siab dhau.Kev ua haujlwm siab ceev ntawm cov kabmob ua kua-lubricated tag nrho yog qhov zoo heev, tshwj xeeb tshaj yog thaum lub hydrostatic zawv zawg bearings siv cua ua cov roj nplaum, nws qhov ceev tuaj yeem ncav cuag 100000r / min.

5. Kev sib piv ntawm lub zog poob

Vim yog qhov sib txhuam me me ntawm cov kabmob dov, lub zog poob feem ntau tsis loj, uas yog me dua li cov kua roj lubricated tsis tiav, tab sis nws yuav nce siab thaum lubrication thiab installation tsis raug.Kev sib txhuam fais fab poob ntawm cov kua roj lubricated tag nrho yog qis dua, tab sis rau hydrostatic zawv zawg bearings, tag nrho lub zog poob yuav siab dua li ntawm hydrodynamic zawv zawg bearings vim lub zog poob ntawm cov roj twj tso kua mis.

6. Kev sib piv ntawm kev pabcuam lub neej

Vim muaj kev cuam tshuam ntawm cov khoom pitting thiab qaug zog, dov bearings feem ntau yog tsim rau 5 mus rau 10 xyoo, los yog hloov thaum lub sij hawm overhaul.Cov kabmob ntawm cov kua roj lubricated tsis tiav yog hnyav hnyav thiab yuav tsum tau hloov tsis tu ncua.Lub neej ntawm tag nrho cov kua lubricated bearing yog theoretically infinite, tab sis nyob rau hauv kev xyaum, vim hais tias ntawm kev nyuaj siab cycles, tshwj xeeb tshaj yog rau hydrodynamic zawv zawg bearings, cov bearings ncoo cov khoom yuav muaj kev qaug zog tsis ua hauj lwm.

7. Kev sib piv ntawm kev sib hloov qhov tseeb

Vim qhov me me radial clearance ntawm dov bearings, qhov kev sib hloov yog feem ntau siab.Cov kua roj lubricated tsis tiav yog nyob rau hauv lub xeev ntawm ciam teb lubrication los yog sib xyaw lubrication, thiab kev ua haujlwm tsis ruaj khov, hnav hnyav, thiab qhov tseeb yog tsawg.Ua kua lubricated bearings muaj siab precision vim muaj roj zaj duab xis, buffering thiab vibration absorption.Lub hydrostatic zawv zawg bearing muaj qhov tseeb dua qhov kev sib hloov.

8. Muab piv rau lwm yam

Rolling bearings siv roj, roj los yog cov roj nplua nyeem. Qhov ntau npaum yog me me, thiab qhov ntau npaum li cas loj ntawm kev kub ceev. Kev ua kom huv ntawm cov roj yuav tsum tau siab, yog li nws yuav tsum tau muab kaw, tab sis cov kabmob yog yooj yim los hloov thiab feem ntau tsis tas yuav kho cov ntawv sau.

Rau zawv zawg bearings, tshwj tsis yog rau lubricated bearings tsis tiav, lub lubricant feem ntau yog kua lossis roj, thiab cov nyiaj ntau, thiab cov roj huv kuj tseem yuav tsum tau ua. Cov kabmob bush yuav tsum tau hloov tsis tu ncua, thiab qee zaum cov ntawv xov xwm raug kho.

2. Kev xaiv cov dov bearings thiab zawv zawg bearings

Vim muaj kev sib txawv thiab kev ua haujlwm tiag tiag, tsis muaj kev sib koom ua ke rau kev xaiv cov kabmob rolling thiab zawv zawg bearings.Vim muaj kev sib txhuam me me, tsis tshua muaj kev pib ua haujlwm, rhiab heev, kev ua haujlwm siab, thiab cov qauv, dov bearings muaj kev sib hloov zoo heev thiab ntau yam, thiab yooj yim heev rau siv, lubricate thiab tswj. dav siv.

Sliding bearings lawv tus kheej muaj qee qhov tshwj xeeb zoo, thiab feem ntau yog siv rau qee lub sijhawm uas nws tsis yooj yim sua, tsis yooj yim lossis tsis muaj txiaj ntsig los siv cov kabmob dov, xws li cov sijhawm hauv qab no:

1. Qhov chaw radial loj yog txwv, los yog lub ntees yuav tsum tau muab faib thiab ntsia

Vim yog lub nplhaib sab hauv, lub nplhaib sab nraud, dov lub cev thiab lub tawb hauv cov qauv ntawm cov kabmob dov, lub radial loj yog loj, thiab daim ntawv thov raug txwv.Thaum cov kev xav tau ntawm radial loj yog nruj, koob rau cov menyuam bearings tuaj yeem xaiv. Thaum tsim nyog, zawv zawg bearings yuav tsum tau xaiv.Rau cov bearings uas tsis yooj yim, los yog tsis tuaj yeem ntsia tau los ntawm cov kev taw qhia axial, thiab qhov chaw uas yuav tsum tau muab tso rau nyias, cais zawv zawg bearings yog siv.

2. Lub sijhawm ua haujlwm siab

Thaum cov bearings siv muaj qhov yuav tsum tau muaj siab precision, zawv zawg bearings feem ntau xaiv, vim hais tias lub lubricating roj zaj duab xis ntawm zawv zawg bearings tuaj yeem tsis thiab nqus kev co. Thaum cov kev xav tau precision siab heev, tsuas yog hydrostatic zawv zawg bearings tuaj yeem xaiv.Rau precision thiab high-precision sib tsoo tshuab, ntau yam precision instruments, thiab lwm yam., zawv zawg bearings yog dav siv.

3. Lub sijhawm ua haujlwm hnyav

Rolling bearings, txawm hais tias lawv yog pob bearings lossis cov menyuam bearings, nws nquag ua kom sov thiab qaug zog hauv daim ntawv thov hnyav.Yog li ntawd, thaum lub load loj, zawv zawg bearings feem ntau siv, xws li dov mills, chav turbines, aero-engine accessories thiab mining machinery.

4. Lwm zaus

Piv txwv li, kev ua haujlwm ceev yog qhov tshwj xeeb, qhov kev poob siab thiab kev vibration yog qhov loj heev, thiab kev ua haujlwm hauv dej lossis corrosive nruab nrab yog qhov yuav tsum tau ua, thiab cov zawv zawg kabmob kuj tuaj yeem xaiv tsim nyog.

Rau ib yam ntawm cov tshuab thiab cov cuab yeej siv, daim ntawv thov ntawm dov bearings thiab zawv zawg bearings muaj qhov zoo thiab qhov tsis zoo, thiab yuav tsum tau xaiv kom tsim nyog raws li qhov tseeb engineering.Yav dhau los, loj thiab nruab nrab-qhov loj me crushers feem ntau siv zawv zawg bearings cam khwb cia nrog babbitt alloys, vim hais tias lawv muaj peev xwm tiv taus tej yam loads loj, thiab kuj hnav-resistant thiab ruaj khov.Lub puab tsaig me me siv cov kabmob dov, uas muaj kev sib kis tau zoo, muaj kev nkag siab ntau dua, thiab yooj yim los tswj.Nrog rau kev txhim kho ntawm dov bearing manufacturing technology, feem ntau loj lub puab tsaig crushers kuj siv dov bearings.
