Vim li cas feem ntau cov tshuab mining xaiv cov bearings dov es tsis txhob siv cov bearings swb?

Raws li ib qho tseem ceeb thiab tseem ceeb hauv cov khoom siv kho tshuab, cov bearings ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa cov ncej tig. Raws li cov yam ntxwv sib txawv ntawm kev sib txhuam hauv cov bearings, cov bearings tau muab faib ua dov kev sib txhuam bearing (hu ua dov bearing) thiab swb kev sib txhuam bearing (hu ua swb bearing). Ob hom bearings muaj lawv tus kheej cov yam ntxwv hauv kev teeb tsa, thiab txhua tus muaj nws tus kheej qhov zoo thiab qhov tsis zoo hauv kev ua tau zoo.

Kev sib piv ntawm cov bearings dov thiab cov bearings tiaj tus

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

Qhov sib txawv pom tseeb tshaj plaws ntawm cov bearings dov thiabcov kabmob tiaj tusyog qhov muaj los yog tsis muaj cov ntsiab lus dov.

Cov kabmob dov muaj cov khoom dov (pob, cov menyuam cylindrical, cov menyuam tapered, cov menyuam koob) uas vam khom lawv txoj kev tig los txhawb lub ncej tig, yog li qhov sib cuag yog ib qho taw tes, thiab cov khoom dov ntau dua, cov ntsiab lus sib cuag ntau dua.

Cov kabmob tiaj tustsis muaj cov khoom dov thiab vam khom cov nplaim du los txhawb lub qag tig, yog li qhov sib cuag yog qhov chaw.

 

Qhov sib txawv ntawm cov qauv ntawm ob qho txiav txim siab tias hom kev txav mus los ntawm kev dov yog dov, thiab hom kev txav mus los ntawm kev swb yog swb, yog li qhov xwm txheej sib txhuam yog txawv kiag li.

 

2. Kev sib piv ntawm lub peev xwm nqa tau

Feem ntau, vim yog thaj chaw loj ntawm cov kabmob swb, nws lub peev xwm thauj khoom feem ntau siab dua li ntawm cov kabmob dov, thiab cov kabmob dov lub peev xwm los dais qhov cuam tshuam tsis siab, tab sis cov kabmob kua-lubricated tag nrho tuaj yeem dais qhov cuam tshuam loj vim yog lub luag haujlwm ntawm cushioning thiab kev co absorbation vim yog cov roj zaj duab xis lubricating. Thaum lub sijhawm tig ceev siab, lub zog centrifugal ntawm cov khoom dov hauv cov kabmob dov nce ntxiv, thiab nws lub peev xwm thauj khoom txo qis (suab nrov feem ntau tshwm sim ntawm qhov ceev siab). Hauv cov ntaub ntawv ntawm cov kabmob dynamic tiaj tus, lawv lub peev xwm thauj khoom nce ntxiv nrog qhov ceev siab dua.

 

3. Kev sib piv ntawm cov coefficient sib txhuam thiab kev pib sib txhuam tsis kam

Nyob rau hauv cov xwm txheej ua haujlwm ib txwm muaj, qhov sib txhuam coefficient ntawm cov kabmob dov qis dua li ntawm cov kabmob tiaj tus, thiab tus nqi ruaj khov dua. Lubrication ntawm cov kabmob swb yooj yim cuam tshuam los ntawm cov yam ntxwv sab nraud xws li kev ceev thiab kev co, thiab qhov sib txhuam coefficient sib txawv ntau.

 

Thaum pib, qhov tsis kam yog ntau dua li ntawm cov kabmob dov vim tias cov kabmob swb tseem tsis tau tsim cov roj zaj duab xis ruaj khov, tab sis qhov pib tsis kam thiab kev sib txhuam ua haujlwm ntawm cov kabmob hydrostatic swb yog me heev.

 

4. Kev sib piv ntawm cov kev ua haujlwm ceev uas siv tau

Vim yog qhov txwv ntawm lub zog centrifugal ntawm lub dov thiab qhov kub nce ntawm cov kabmob, qhov ceev ntawm cov dov kabmob tsis tuaj yeem siab dhau, thiab nws feem ntau haum rau qhov nruab nrab thiab qis ceev ua haujlwm. Cov kabmob kua roj tsis tiav vim yog cua sov thiab hnav ntawm cov kabmob, qhov ceev ua haujlwm yuav tsum tsis txhob siab dhau. Kev ua haujlwm ceev ntawm cov kabmob kua roj puv nkaus zoo heev, tshwj xeeb tshaj yog thaum cov kabmob hydrostatic tiaj tus tau lubricated nrog cua, thiab lawv qhov ceev tig tuaj yeem ncav cuag 100,000 r / min.

 

5. Kev sib piv ntawm kev poob hwj chim

Vim yog qhov coefficient sib txhuam me me ntawm cov bearings dov, lawv lub zog poob feem ntau tsis loj, uas yog tsawg dua li ntawm cov kua roj lubricated tsis tiav, tab sis nws yuav nce ntxiv thaum lubricated thiab ntsia kom raug. Lub zog poob ntawm cov kua roj lubricated tag nrho yog qis, tab sis rau cov bearings hydrostatic tiaj tus, tag nrho lub zog poob yuav siab dua li ntawm cov hydrostatic tiaj tus bearings vim yog qhov poob ntawm lub zog twj roj.

 

6. Kev sib piv ntawm lub neej ua haujlwm

Vim yog qhov cuam tshuam ntawm cov khoom siv pitting thiab qaug zog, cov kabmob dov feem ntau yog tsim los rau 5 ~ 10 xyoo, lossis hloov pauv thaum lub sijhawm kho dua tshiab. Cov ntaub qhwv ntawm cov kabmob tsis tiav-lubricated kua yog hnav hnyav heev thiab yuav tsum tau hloov pauv tsis tu ncua. Lub neej ntawm cov kabmob kua-lubricated tag nrho yog qhov tsis txwv, tab sis hauv kev xyaum ua haujlwm qaug zog tsis ua haujlwm ntawm cov khoom siv bearing tuaj yeem tshwm sim vim yog kev ntxhov siab cycling, tshwj xeeb tshaj yog rau cov kabmob dynamic tiaj tus.

 

7. Kev sib piv ntawm qhov tseeb ntawm kev sib hloov

Feem ntau cov bearings dov muaj qhov tseeb tig siab vim yog qhov me me radial clearance. Cov bearings kua roj tsis tiav yog nyob rau hauv lub xeev ntawm ciam teb lubrication lossis sib xyaw lubrication, thiab kev ua haujlwm tsis ruaj khov, thiab kev hnav yog qhov loj, thiab qhov tseeb yog qis. Vim muaj cov roj zaj duab xis, cov bearings kua roj puv nkaus cushions thiab nqus cov kev co nrog qhov tseeb siab. Hydrostatic plain bearings muaj qhov tseeb tig siab dua.

 

8. Kev sib piv ntawm lwm yam

Cov kabmob dov siv roj, roj lossis cov roj nplaum khov, qhov ntau me me heev, qhov ntau loj ntawm qhov ceev ceev, qhov huv ntawm cov roj yuav tsum siab, yog li nws yuav tsum tau kaw, tab sis cov kabmob yooj yim hloov, thiab feem ntau tsis tas yuav kho cov ntawv xov xwm. Rau cov kabmob tiaj tus, ntxiv rau cov kabmob kua roj tsis tiav, cov roj nplaum feem ntau yog kua lossis roj, qhov ntau loj heev, qhov yuav tsum tau ntxuav roj kuj siab heev, cov ntaub qhwv kabmob yuav tsum tau hloov ntau zaus, thiab qee zaum cov ntawv xov xwm raug kho.

 

Kev xaiv ntawm cov bearings dov thiab cov bearings tiaj tus

Vim yog qhov nyuaj thiab ntau yam kev ua haujlwm tiag tiag, tsis muaj tus qauv sib koom ua ke rau kev xaiv cov kabmob dov thiab cov kabmob swb. Vim yog qhov sib txhuam me me, kev tiv thaiv pib me me, kev rhiab heev, kev ua haujlwm siab, thiab kev teeb tsa tus qauv, cov kabmob dov muaj kev sib pauv zoo heev thiab kev hloov pauv tau yooj yim, thiab yooj yim siv, roj thiab tswj, thiab feem ntau tau muab qhov tseem ceeb hauv kev xaiv, yog li lawv siv dav hauv cov tshuab dav dav. Cov kabmob tiaj tus lawv tus kheej muaj qee qhov zoo tshwj xeeb, uas feem ntau siv rau qee lub sijhawm uas cov kabmob dov tsis tuaj yeem siv, tsis yooj yim lossis tsis muaj qhov zoo, xws li cov sijhawm hauv qab no:

 

1. Qhov chaw radial loj me me, lossis qhov kev teeb tsa yuav tsum tau faib

Vim yog lub nplhaib sab hauv, lub nplhaib sab nraud, lub ntsiab dov thiab lub tawb hauv cov qauv, qhov loj me radial ntawm cov kabmob dov yog loj, thiab daim ntawv thov tsuas yog txwv rau qee qhov. Cov kabmob koob muaj thaum qhov loj me radial nruj, thiab yog tias tsim nyog, xav tau cov kabmob tiaj tus. Rau cov khoom uas tsis yooj yim kom muaj cov kabmob, lossis tsis tuaj yeem ntsia tau los ntawm qhov kev taw qhia axial, lossis qhov twg cov khoom yuav tsum tau faib ua ntu, cov kabmob tiaj tus sib cais yog siv.

 

2. Cov sijhawm ua haujlwm siab

Thaum cov kabmob siv muaj qhov yuav tsum tau ua kom raug, feem ntau cov kabmob swb raug xaiv, vim tias cov roj nplaum ntawm cov kabmob swb tuaj yeem tiv thaiv kev co, thiab thaum qhov tseeb siab heev, tsuas yog cov kabmob swb hydrostatic tuaj yeem xaiv tau. Rau cov tshuab sib tsoo precision thiab siab precision, ntau yam twj paj nruag precision, thiab lwm yam, cov kabmob swb tau siv dav.

 

3. Cov sijhawm hnyav

Cov kabmob dov, txawm tias yog cov kabmob pob lossis cov kabmob dov, feem ntau yuav kub thiab qaug zog thaum ua haujlwm hnyav. Yog li ntawd, thaum lub nra hnyav, cov kabmob swb feem ntau siv, xws li cov tshuab dov, cov tshuab ua pa, cov khoom siv cav dav hlau thiab cov tshuab tsuas.

 

4. Lwm lub sijhawm

Piv txwv li, qhov ceev ua haujlwm yog qhov siab tshwj xeeb, qhov poob siab thiab kev co yog qhov loj heev, thiab qhov xav tau ua haujlwm hauv dej lossis cov xov xwm corrosive, thiab lwm yam, cov kabmob swb kuj tuaj yeem xaiv tau zoo.

 

Rau ib hom tshuab thiab khoom siv, kev siv cov bearings dov thiab cov bearings swb, txhua tus muaj nws tus kheej qhov zoo thiab qhov tsis zoo, thiab yuav tsum tau xaiv kom zoo ua ke nrog qhov project tiag tiag. Yav dhau los, cov crushers loj thiab nruab nrab feem ntau siv cov bearings swb uas cam khwb cia nrog babbitt, vim tias lawv tuaj yeem tiv taus cov khoom hnyav loj, thiab muaj kev hnav-resistant thiab ruaj khov dua. Lub puab tsaig crusher me me feem ntau siv nrog cov bearings dov, uas muaj kev sib kis zoo, muaj kev nkag siab ntau dua thiab yooj yim rau kev tswj hwm. Nrog kev txhim kho ntawm qib kev tsim khoom ntawm cov kabmob dov, feem ntau ntawm cov hniav tawg loj kuj siv rau hauv cov bearings dov.
