Kev ceev faj txog kev teeb tsa bearing
2022-02-23
Seb tusbearingyog ntsia kom raug cuam tshuam rau qhov raug, lub neej thiab kev ua haujlwm. Yog li ntawd, lub tuam tsev tsim thiab sib dhos yuav tsum tau kawm tag nrho covbearingkev teeb tsa. Nws cia siab tias qhov kev teeb tsa yuav ua tiav raws li tus qauv ua haujlwm. Cov khoom ntawm cov qauv kev ua haujlwm feem ntau yog raws li hauv qab no:
(1) Ntxuav cov kabmob thiab cov kabmob muaj feem xyuam
(2) Txheeb xyuas qhov ntev thiab kev ua tiav ntawm cov khoom muaj feem xyuam
(3) Kev teeb tsa
(4) Kev tshuaj xyuas tom qab cov kabmob raug teeb tsa
(5) Muab cov roj nplua nyeem
Nws vam tias covbearingntim yuav qhib ua ntej installation. General roj lubrication, tsis muaj tu, ncaj qha sau nrog roj. Lubricating roj tsis tas yuav tsum tau ntxuav kom huv. Txawm li cas los xij, bearings rau cov twj paj nruag lossis kev siv ceev ceev yuav tsum tau ntxuav nrog cov roj huv kom tshem tawm cov xeb inhibitor coated ntawm cov bearings. Cov bearings nrog xeb inhibitor tshem tawm yog yooj yim rau xeb, yog li lawv tsis tuaj yeem tso tseg tsis tuaj saib. Tsis tas li ntawd,bearingsuas tau raug kaw nrog roj tuaj yeem siv ncaj qha yam tsis muaj kev ntxuav.
Txoj kev teeb tsa ntawm cov kabmob sib txawv nyob ntawm tus qauv kabmob, haum thiab cov xwm txheej. Feem ntau, txij li feem ntau ntawm cov shafts tig, lub nplhaib puab xav tau kev cuam tshuam haum. Cylindrical bore bearings feem ntau yog nias los ntawm ib lub xovxwm, los yog los ntawm txoj kev shrink-haum. Nyob rau hauv cov ntaub ntawv ntawm ib tug tapered qhov, nruab nws ncaj qha rau ntawm tapered ncej, los yog nruab nrog ib lub tes tsho.
Thaum txhim kho rau lub plhaub, feem ntau muaj ntau qhov kev tshem tawm kom haum, thiab lub nplhaib sab nrauv muaj qhov cuam tshuam, uas feem ntau yog nias rau ntawm ib lub xovxwm, los yog muaj ib txoj kev shrink haum rau installation tom qab txias. Thaum cov dej khov qhuav yog siv los ua ib qho coolant thiab shrink haum yog siv rau installation, noo noo nyob rau hauv cov huab cua yuav condense rau saum npoo ntawm cov kabmob. Yog li ntawd, yuav tsum muaj kev tiv thaiv xeb tsim nyog.
