Lub cev muaj zog yog ib feem tseem ceeb ntawm lub cev muaj zog, yog ib qho tseem ceeb ntawm cov khoom siv kho tshuab ntawm lub cev muaj zog uas muaj nyob rau hauv cov khoom tseem ceeb, kom ua kom lub cev muaj zog muaj txiaj ntsig zoo.lub cev muaj zog, ua ntej tshaj plaws yuav tsum nkag siab txog cov teeb meem hauv qab no.
1, Pem hauv ntej thiab nram qab lub cev muaj zog
Lub pem hauv ntej ntawm lub cev muaj zog yog hais txog lub bearing ze rau sab thauj khoom, tseem hu ua lub load sab bearing lossis axial kawg bearing; lublub log tsheb tom qabhais txog cov kabmob ze rau sab kiv cua txias, tseem hu ua kiv cua sab bearing lossis non-axial end bearing.
2, Nrhiav qhov kawg thiab qhov kawg dawb ntawm lub cev muaj zog
Qhov kawg ntawm qhov chaw thiab qhov kawg dawb yog cov lus tshwj xeeb rau cov qauv ntawm lub cev muaj zog bearing system. Thaum lub sijhawm ua haujlwm ntawm lub cev muaj zog, vim muaj ntau yam xws li thermal expansion thiab contraction ntawm cov khoom, magnetic tension ntawm stator thiab rotor, thiab lwm yam, qee qhov kev txav axial yuav tshwm sim ntawm stator thiab rotor. Yuav kom ua tau raws li qhov kev hloov pauv axial thiab cov teeb meem hloov chaw uas tshwm sim hauv cov khoom, yuav tsum muaj qee qhov chaw axial hauv kev tsim thiab kev tsim khoom ntawm lub cev muaj zog. Vim li no, thaum teeb tsa lub cev muaj zog bearing system, lub nplhaib sab nraud ntawm bearing yuav raug kho kom nruj ntawm ib qho kawg, piv txwv li, qhov axial displacement ntawm bearing ntawm qhov kawg no yuav tsis raug tso cai tshwm sim, thiab qhov kawg no yuav raug hu ua qhov kawg nrhiav lossis qhov kawg ruaj khov; thiab lub cev muaj zog ntawm qhov kawg ntawm lub cev muaj zog yuav tawm qee qhov axial clearance kom haum nrog lub nplhaib sab nraud ntawm cov kabmob los ntawm qhov axial haum qhov ntev ntawm sab hauv thiab sab nraud bearing caps thiab lub hau kawg, txhawm rau kom ntseeg tau tias lub rotor ib feem muaj qhov xav tau axial displacement hauv cov txheej txheem ntawm kev ua haujlwm ntawm lub cev muaj zog, txij li qhov kawg muaj axial mobility, yog li qhov kawg hu ua qhov kawg dawb lossis qhov kawg ntab.
3, Cov kabmob sib sib zog nqus thiab cov kabmob cylindrical
Cov kabmob sib sib zog nqus tuaj yeem txwv txoj kev txav ntawm ob txoj kev ntawm tus ncej, qhov tseeb siab, qhov sib txhuam qis, yog qhov kev xaiv zoo tshaj plaws rau qhov kawg ntawm lub cev muaj zog, lub pob thiab lub tes tsho bearing rau kev sib cuag kab, uas yog, cov txheej txheem khiav ntawm cov kabmob ntawm kev sib cuag rau lub nplhaib kab ncig, qhov chaw sib cuag me me, lub peev xwm thauj khoom radial tsis loj, tsis haum rau kev thauj khoom cuam tshuam thiab cov khoom hnyav; thiab cov menyuam cylindrical tsis muaj kev txwv axial ntawm cov menyuam, ua qhov kawg dawb ntawm kev txhawb nqa uas yuav tsum tau siv, tuaj yeem hloov kho rau kev nthuav dav thermal lossis kev teeb tsa yuam kev los ntawm qhov chaw hloov pauv ntawm tus ncej thiab lub plhaub, cov menyuam thiab txoj kab sib cuag, cov kabmob khiav yog lub nplhaib voj voog, qhov chaw sib cuag loj dua, lub peev xwm thauj khoom radial, haum rau kev thauj khoom hnyav thiab kev co.
4, lub cev muaj zog qhov chaw xaiv qhov kawg
Los ntawm kev ua haujlwm tiag tiag ntawm lub cev muaj zog thiab kom ua tau raws li cov khoom siv sib phim nrog cov kev txiav txim siab ua raws li docking, qhov kawg ntawm qhov chaw xaiv dav dav hauv qhov kawg axial, thiab rau qhov yuav tsum tau ua haujlwm axial tsis yog cov xwm txheej nruj, kuj tuaj yeem xaiv hauv qhov kawg tsis yog axial, nyiam qhov yuav tsum tau ua haujlwm ntawm lub cev muaj zog; tab sis yog tias cov khoom siv rub ntawm lub cev muaj zog axial khiav tawm muaj cov kev cai nruj dua, ces qhov kawg ntawm lub cev muaj zog yuav tsum tau xaiv hauv qhov kawg axial. Qhov kawg tso tawmlub nplhaib sab nraudlos ntawm sab hauv thiab sab nraud lub hau npog nres tuag, lub hau npog khi rau lub tes tsho npog lossis lub hau kawg.
5, Kev xaiv hom kev tsav tsheb
Thaum lub cev muaj zog nqa tsis loj, feem ntau siv cov kabmob sib sib zog nqus; thiab raws li qhov yuav tsum tau ua ntawm cov xwm txheej ua haujlwm tiag tiag, rau cov khoom thauj hnyav, nrog rau cov khoom thauj loj dua, cov kabmob cylindrical roller yuav tsum tau siv rau hauv qhov kawg axial ntawm lub cev muaj zog, piv rau tib qhov loj ntawm cov kabmob sib sib zog nqus, cov kabmob cylindrical roller radial bearing muaj peev xwm nce ntxiv los ntawm 1.5-3 zaug, rigidity thiab kev tiv thaiv kev co zoo dua. Cov kabmob sib sib zog nqus muaj zog radial dua li cov kabmob cylindrical roller tsis muaj zog, tab sis tuaj yeem nqa qee qhov axial force, thaum cov kabmob cylindrical roller tsis tuaj yeem nqa axial force. Vim yog cov kabmob sib sib zog nqus thiab cov kabmob cylindrical roller muaj cov yam ntxwv ntawm cov qauv, rau qhov xav tau los teeb tsa cov kabmob cylindrical roller rau lub cev muaj zog, yuav tsum tau teeb tsa siv hom sib xyaw, uas yog, yuav tsum muaj tsawg kawg ib pawg ntawm cov kabmob sib sib zog nqus nrog nws siv.
Lub zog ntawm cov cav hluav taws xob siab feem ntau loj heev, txhawm rau kom tau raws li qhov hnyav thiab kev tswj hwm me me ntawm axial, feem ntau raws li tus qauv teeb tsa ntawm peb-bearing qauv. Txhawm rau txhim kho lub peev xwm thiab lub neej ua haujlwm ntawm axial extension kawg bearing, hauv axial extension kawg nrog ib pawg ntawm cylindrical roller bearings thiab ib pawg ntawm cov pob sib sib zog nqus groove sab ntawm sab, cylindrical roller bearings los dais radial loads, thiab cov pob sib sib zog nqus groove rau qhov chaw bearing axis, tsuas yog dais axial loads (thiab yog li ntawd lub pob sib sib zog nqus groove sab nraud nplhaib thiab lub tes tsho bearing radial feem ntau tawm qee qhov clearance); lwm qhov kawg ntawm lub cev muaj zog raws li qhov xav tau tiag tiag los xaiv cov pob sib sib zog nqus groove, yog tias tsim nyog, koj tuaj yeem xaiv lwm qhov kawg ntawm lub cev muaj zog raws li qhov xav tau tiag tiag, thiab cylindrical roller bearings kuj tuaj yeem xaiv yog tias tsim nyog.
Yuav kom tiv thaiv cov bearings kom tsis txhob khiav hauv lub cev muaj zog, lub nplhaib sab nraud ntawm cov kabmob thiab chav bearing, lub nplhaib sab hauv ntawm cov kabmob thiab lub ncej yuav tsum xaiv qhov haum uas haum; Txawm tias nws yog qhov kawg ntawm lub cuab yeej bearing, lossis qhov kawg uas tsis yog axial ntawm lub cuab yeej bearing, muaj cov qauv labyrinthine, thiab lub nplhaib sealing raug kaw, tsis yog tsuas yog tiv thaiv cov roj nplua nyeem hauv chav bearing kom tsis txhob nkag mus rau sab hauv ntawm lub cev muaj zog, ua rau lub rwb thaiv tsev puas tsuaj, tab sis kuj tiv thaiv cov hmoov av lossis dej nkag mus rau hauv chav bearing sab nraud, kom cov bearings huv. Nws kuj tiv thaiv cov hmoov av lossis dej sab nraud kom tsis txhob nkag mus rau hauv chav bearing thiab ua kom cov bearings huv.
Lub cev muaj zog siab yuav tsum tau nruab nrog cov roj filling thiab draining kav dej kom yooj yim hloov cov roj, thiab tuaj yeem ua tiav kev refueling lossis draining tsis tu ncua.
