1, Txhawm rau xaiv cov bearings haum rau cov tshuab sib txawv los ntawm ntau txoj kev xaiv, peb yuav tsum tau them sai sai rau ob lub ntsiab lus tseem ceeb:
1. Yuav tsum tsim nyog rau kev siv ib puag ncig ntawm cov tshuab thiab cov kev xav tau ntawm cov bearings
2. Nws yog ib qho yooj yim mus yuav hloov bearings rau kev kho thiab tshuaj xyuas
2, Kev txiav txim siab ntawm ntau yam tseem ceeb
Tsis muaj kev ruaj ntseg rau kev xaiv hom kabmob. Thaum xaiv cov bearing hom kom hloov mus rau ib qho chaw tshwj xeeb installation thiab daim ntawv thov, nws raug nquahu kom xav txog cov hauv qab no tseem ceeb tshaj plaws.
1. Raws li cov kabmob muaj peev xwm thiab qhov loj me
Txhawm rau xaiv ib hom kabmob, ua ntej xaiv cov kabmob uas tsim nyog raws li cov kabmob ntawm cov kabmob cov kabmob thiab qhov loj, thiab tom qab ntawd xaiv cov kabmob uas tsim nyog los ntawm cov kabmob sib thooj ntawm cov kabmob loj raws li qhov loj ntawm cov kabmob sib txuam lossis cov kabmob rooj zaum:
(1) Thaum feem ntau bearing radial loads, radial bearings tuaj yeem xaiv, thiab thaum feem ntau bearing axial loads, piv txwv li thrust loads, axial bearings feem ntau xaiv.
(2) Pob bearings tuaj yeem xaiv tau thaum lub load ntawm cov kabmob me me, thiab cov menyuam bearings feem ntau xaiv thaum lub load loj.
(3) Thaum cov kabmob raug rau ob qho tib si radial thiab axial loads, yog tias qhov sib xyaw ua ke me me, qhov sib sib zog nqus groove pob lossis angular contact pob bearings tuaj yeem xaiv. Yog hais tias lub load yog loj, tapered roller bearings feem ntau xaiv. Thaum bearing loj bi-directional axial loads, nws yog advisable xaiv ib tug ua ke ntawm ob los yog ntau tshaj bearings los yog ob kab kab bearings.
2. Raws li kev tshem tawm, qhov kub thiab txias, thiab kev siv ib puag ncig
Cov kev xaiv ntawm clearance yog ncaj qha ntsig txog cov kev pab cuam, bearing ceev, kub, thiab haum haum rau cov kabmob. Piv txwv li, lub cev muaj zog nrog ceev qis dua 3500 rpm feem ntau siv CM tshem tawm. Rau cov high-temperature high-ceev motors, yuav tsum tau loj clearance. Nyob rau hauv txoj kev xav, lub suab nrov thiab lifespan ntawm bearings ncav cuag lawv qhov zoo tshaj plaws lub xeev ntawm xoom clearance. Txawm li cas los xij, hauv kev ua haujlwm, qhov kub thiab txias thiab lwm yam teeb meem raug txiav txim siab, thiab kev tshem tawm ntawm cov kabmob tom qab sib dhos yog 0.002mm-0.005mm. Tau kawg, thaum nws los txog rau qhov chaw tshwj xeeb xws li qhov kub thiab txias, tsis tshua muaj kub, thiab lub tshuab nqus tsev, kuj tseem muaj cov kev xaiv tshwj xeeb uas muaj nyob. Tshwj xeeb bearings rau kev ua haujlwm tshwj xeeb
3. Raws li roj thiab sealing
Tom ntej no yog kev xaiv cov kabmob roj:
Kev xaiv cov roj feem ntau suav hais tias yog raws li cov xwm txheej xws li cov kabmob ceev, qhov kub thiab txias, kev xav tau suab nrov, thiab pib lub zog. Xav txog kev sib khi ntawm bearings, lubrication ntawm bearings tuaj yeem muab faib ua roj lubrication thiab roj lubrication. Roj lubricated bearings feem ntau siv qhib bearings, thaum roj lubricated bearings feem ntau siv plua plav npog lossis roj hmab foob.
Raws li kev txiav txim siab ntawm kev ntsuas kev ua tau zoo xws li kev coj tus kheej lub neej, kev muaj peev xwm ntawm cov kabmob, kev ceev, thiab qhov kub thiab txias, yog tias muaj ntau tshaj ib cov kabmob ua tau raws li qhov yuav tsum tau ua, cov kabmob uas muaj kev lag luam zoo tshaj plaws thiab kev ua haujlwm zoo yuav tsum raug xaiv.
