Vim li cas feem ntau cov tshuab mining xaiv dov bearings es tsis txhob zawv zawg bearings?

Raws li qhov tseem ceeb thiab tseem ceeb ntawm cov khoom siv kho tshuab, bearings ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa rotating shafts. 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 yam ntxwv hauv cov qauv, thiab txhua tus muaj nws qhov zoo thiab qhov tsis zoo hauv kev ua haujlwm.

Kev sib piv ntawm dov thiab dawb bearings

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

Qhov pom tseeb tshaj qhov sib txawv ntawm dov bearings thiabdawb bearingsyog muaj los yog tsis muaj cov ntsiab lus dov.

Rolling bearings muaj dov cov ntsiab lus (pob, cylindrical rollers, tapered rollers, koob chais) uas tso siab rau lawv cov kev sib hloov los txhawb lub rotating ncej, yog li qhov kev sib cuag yog qhov taw tes, thiab cov ntsiab lus dov ntau dua, cov ntsiab lus sib cuag ntau dua.

Plain bearingstsis muaj cov ntsiab lus dov thiab tso siab rau ntawm qhov chaw du los txhawb lub rotating ncej, yog li qhov kev sib cuag yog qhov chaw.

 

Qhov sib txawv ntawm cov qauv ntawm ob qho kev txiav txim siab tias txoj kev 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 yog sib txawv kiag li.

 

2. Kev sib piv ntawm lub peev xwm nqa

Feem ntau, vim muaj qhov loj ntawm cov kabmob zawv zawg kabmob, nws cov kabmob muaj peev xwm 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 ua kua-lubricated tag nrho tuaj yeem dais. ib tug loj cuam tshuam load vim lub luag hauj lwm ntawm cushioning thiab vibration absorption vim lub lubricating roj zaj duab xis. Thaum qhov kev sib hloov ceev yog siab, lub zog centrifugal ntawm cov khoom dov hauv cov kabmob dov nce, thiab nws lub peev xwm thauj khoom raug txo qis (lub suab nrov yog tshwm sim ntawm kev kub ceev). Nyob rau hauv cov ntaub ntawv ntawm dynamic tiaj bearings, lawv load-bearing muaj peev xwm nce nrog siab dua speeds.

 

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

Nyob rau hauv ib txwm ua hauj lwm tej yam kev mob, kev sib txhuam coefficient ntawm dov bearings yog qis dua li ntawm cov bearings dawb, thiab tus nqi yog ruaj khov dua. Lub lubrication ntawm zawv zawg bearings tau yooj yim cuam tshuam los ntawm lwm yam xws li kev ceev thiab kev co, thiab kev sib txhuam coefficient sib txawv.

 

Thaum pib, qhov tsis kam yog ntau dua li ntawm cov kabmob dov vim tias cov zawv zawg kabmob tseem tsis tau tsim cov roj av ruaj khov, 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, qhov ceev ntawm cov kabmob dov tsis tuaj yeem siab dhau, thiab nws feem ntau haum rau nruab nrab thiab qis ceev ua haujlwm. Ua tsis tiav kua lubricated bearings vim cua sov thiab hnav ntawm cov kabmob, kev ua haujlwm ceev yuav tsum tsis txhob siab dhau. Kev ua haujlwm siab ceev ntawm cov kua roj lubricated tag nrho yog qhov zoo heev, tshwj xeeb tshaj yog thaum cov kabmob uas muaj cov kabmob hydrostatic yog lubricated nrog cua, thiab lawv cov kev sib hloov ceev tuaj yeem ncav cuag 100,000 r / min.

 

5. Kev sib piv ntawm lub zog poob

Vim yog qhov sib txhuam me me ntawm cov kabmob dov, lawv lub zog poob feem ntau tsis loj, uas yog tsawg dua li cov kua roj lubricated tsis tiav, tab sis nws yuav nce siab heev thaum lubricated thiab txhim kho kom zoo. Kev sib txhuam lub zog poob ntawm cov kua roj lubricated tag nrho yog qhov tsawg, tab sis rau hydrostatic plain bearings, tag nrho cov hluav taws xob poob yuav siab dua li ntawm hydrostatic plain bearings vim qhov poob ntawm cov roj twj tso kua mis lub zog.

 

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 ~ 10 xyoo, los yog hloov thaum lub sij hawm overhaul. Cov ntaub qhwv 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 bearings yog theoretically unlimited, tab sis nyob rau hauv kev xyaum qaug zog tsis ua hauj lwm ntawm cov bearings yuav tshwm sim vim kev nyuaj siab cycling, tshwj xeeb tshaj yog rau dynamic tiaj bearings.

 

7. Kev sib piv ntawm kev sib hloov qhov tseeb

Rolling bearings feem ntau muaj kev sib hloov qhov tseeb vim qhov me me radial clearance. 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, thiab hnav hnyav, thiab qhov tseeb yog tsawg. Vim muaj cov roj zaj duab xis, lub siab ua kua-lubricated bearing cushions thiab absorbs kev co nrog cov neeg siab. Hydrostatic plain bearings muaj kev sib hloov ntau dua.

 

8. Kev sib piv ntawm lwm yam

Rolling bearings siv cov roj, roj lossis cov roj lubricating, cov nyiaj tsawg heev, qhov loj ntawm kev kub ceev, kev huv ntawm cov roj yuav tsum 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 xov xwm. Rau cov kabmob dawb, ntxiv rau cov kua roj lubrication tsis tiav, cov roj nplua nyeem feem ntau yog kua lossis roj, cov nyiaj ntau heev, cov roj huv huv yuav tsum muaj siab heev, cov kabmob cov kabmob yuav tsum tau hloov tsis tu ncua, thiab qee zaum cov ntaub ntawv raug kho. .

 

Kev xaiv ntawm dov bearings thiab dawb 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, me me pib tsis kam, rhiab heev, kev ua haujlwm siab, thiab kev tsim qauv, dov bearings muaj kev sib hloov zoo thiab ntau yam, thiab yooj yim siv, lubricate thiab tswj, thiab feem ntau muab qhov tseem ceeb hauv kev xaiv, yog li lawv tau dav siv. hauv cov tshuab dav dav. Plain bearings lawv tus kheej muaj qee qhov tshwj xeeb zoo, uas feem ntau siv rau qee lub sijhawm uas cov kabmob dov tsis tuaj yeem siv, tsis yooj yim lossis tsis muaj txiaj ntsig, xws li cov sijhawm hauv qab no:

 

1. Lub radial qhov chaw loj yog txwv, los yog lub installation yuav tsum tau muab faib

Vim lub nplhaib sab hauv, lub nplhaib sab nraud, cov khoom dov thiab lub tawb hauv cov qauv, qhov loj ntawm cov kabmob dov yog qhov loj, thiab daim ntawv thov raug txwv rau qee yam. Koob cov menyuam bearings muaj nyob rau thaum radial qhov ntev yog nruj, thiab yog tias tsim nyog, cov bearings dawb yuav tsum. Rau qhov chaw uas tsis yooj yim kom muaj bearings, los yog tsis tuaj yeem mounted los ntawm axial kev taw qhia, los yog qhov chaw yuav tsum tau muab faib mus rau hauv qhov chaw, cais cov bearings yog siv.

 

2. Lub sijhawm ua haujlwm siab

Thaum cov kabmob siv muaj qhov yuav tsum tau muaj siab, zawv zawg kabmob feem ntau xaiv, vim tias cov roj lubricating ntawm cov kabmob zawv zawg tuaj yeem tsis muaj kev vibration absorption, thiab thaum qhov tseeb yog qhov siab heev, tsuas yog cov kabmob zawv zawg tuaj yeem xaiv tau. Rau precision thiab high-precision sib tsoo tshuab, ntau yam cuab yeej precision, thiab lwm yam, zawv zawg bearings yog dav siv.

 

3. Lub sijhawm ua haujlwm hnyav

Rolling bearings, txawm tias pob bearings los yog cov menyuam bearings, yog nquag cua sov thiab qaug zog hauv cov xwm txheej hnyav. Yog li ntawd, thaum lub load loj, zawv zawg bearings feem ntau yog 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 co yog qhov loj heev, thiab qhov yuav tsum tau ua haujlwm hauv dej lossis corrosive media, thiab lwm yam, zawv zawg bearings 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, txhua tus muaj nws tus kheej qhov zoo thiab qhov tsis zoo, thiab yuav tsum tau xaiv kom tsim nyog nrog rau qhov project tiag tiag. Yav dhau los, cov crushers loj thiab nruab nrab feem ntau siv zawv zawg bearings cam khwb cia nrog babbitt, vim hais tias lawv tuaj yeem tiv taus cov khoom loj, thiab hnav-tiv taus thiab ruaj khov. Lub puab tsaig me me crusher feem ntau yog siv nrog dov bearings, uas muaj kev sib kis tau zoo, muaj kev nkag siab ntau dua thiab yooj yim los tswj. Nrog rau kev txhim kho cov txheej txheem ntawm kev tsim cov yob bearing, feem ntau ntawm lub puab tsaig loj loj kuj tau siv rau hauv cov kabmob dov.
