Bearing system yog ib qho tseem ceeb ntawm lub cev muaj zog, yog ib qho tseem ceeb ntawm cov khoom siv ntawm lub cev muaj zog embodied nyob rau hauv cov khoom tseem ceeb, kom rationally configure lub cev muaj zog.bearing system, ua ntej ntawm tag nrho cov yuav tsum to taub cov teeb meem nram qab no.
1 、 Pem hauv ntej bearing thiab rear bearing ntawm lub cev muaj zog
Cov kabmob pem hauv ntej ntawm lub cev muaj zog yog hais txog cov kabmob ze rau ntawm lub tshuab thauj khoom, tseem hu ua load side bearing lossis axial kawg bearing; tusrear bearinghais txog cov kabmob ze rau ntawm lub kiv cua txias, tseem hu ua kiv cua sab bearing lossis non-axial kawg bearing.
2 、 Nrhiav qhov kawg thiab dawb kawg ntawm lub cev muaj zog
Nrhiav qhov kawg thiab dawb kawg yog cov lus qhia 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, sib nqus nro ntawm stator thiab rotor, thiab lwm yam, ib qho kev txav ntawm axial yuav tshwm sim ntawm stator thiab rotor. Txhawm rau kom ua tau raws li qhov hloov pauv ntawm axial dimensional thiab cov teeb meem kev hloov pauv uas tshwm sim hauv cov khoom, qee qhov ntawm qhov chaw axial yuav tsum tau tso rau hauv kev tsim thiab tsim ntawm lub cev muaj zog. Vim li no, thaum teeb tsa cov kabmob ntawm lub cev muaj zog, lub nplhaib sab nraud ntawm cov kabmob yuav raug kho kom nruj ntawm ib kawg, piv txwv li, axial hloov pauv ntawm cov kabmob ntawm qhov kawg no yuav tsis tso cai tshwm sim, thiab qhov kawg no yuav raug tso cai. hu ua qhov chaw qhov kawg lossis qhov kawg ruaj khov; thiab cov kabmob uas nyob rau lwm qhov kawg ntawm lub cev muaj zog yuav tawm ntawm qee qhov ntawm axial clearance kom haum nrog lub nplhaib sab nraud ntawm cov kabmob los ntawm axial haum qhov ntev ntawm cov kabmob sab hauv thiab sab nraud thiab lub hau kawg, txhawm rau xyuas kom meej tias lub rotor ib feem muaj qhov yuav tsum tau axial hloov chaw nyob rau hauv cov txheej txheem ntawm lub cev muaj zog ua hauj lwm, txij li thaum kawg muaj axial mobility, yog li qhov kawg yog hu ua dawb kawg los yog floating kawg.
3 、 Sib sib zog nqus groove pob bearings thiab cylindrical roller bearings
Sib sib zog nqus groove pob bearings tuaj yeem txwv ob txoj kev txav ntawm lub ncej, siab precision, qis coefficient ntawm kev sib txhuam, yog qhov kev xaiv zoo tshaj plaws rau lub cev muaj zog qhov kawg, lub pob thiab lub tes tsho bearing rau kab kev sib cuag, uas yog, cov txheej txheem khiav ntawm cov kabmob. Kev sib cuag ntawm lub nplhaib nplhaib, qhov chaw sib cuag yog me me, lub peev xwm radial load tsis loj, tsis haum rau kev tiv thaiv kev cuam tshuam thiab hnyav loads; thiab cylindrical roller bearings tsis muaj kev txwv axial ntawm cov menyuam, ua qhov kawg ntawm kev txhawb nqa los siv, tuaj yeem hloov kho rau thermal expansion lossis installation yuam kev tshwm sim los ntawm cov ncej thiab lub plhaub txheeb ze txoj hauj lwm hloov, cov menyuam thiab cov kev sib tw yog kab sib cuag, cov kabmob khiav. khiav yog lub nplhaib ncig, kev sib cuag saum npoo yog loj dua, radial load nqa lub peev xwm, tsim nyog rau cov kabmob hnyav thiab kev poob siab.
4, lub cev muaj zog bearing positioning kawg xaiv
Los ntawm kev ua haujlwm tiag tiag ntawm lub cev muaj zog thiab ua kom tau raws li cov khoom siv sib txuam nrog kev txiav txim siab docking, qhov kawg ntawm kev xaiv nyob rau hauv axial kawg, thiab rau cov kev cai ntawm axial txheeb ze txoj hauj lwm yuav tsis nruj heev, kuj tuaj yeem xaiv nyob rau hauv qhov tsis. -axial kawg, zoo li lub cev muaj zog load yuav tsum tau; tab sis yog hais tias cov khoom siv towed ntawm lub cev muaj zog axial runout muaj qhov yuav tsum tau nruj dua, ces lub cev muaj zog bearing qhov kawg yuav tsum tau xaiv nyob rau hauv qhov kawg axial. Positioning kawgbearing lub nplhaib sab nraudlos ntawm sab hauv thiab sab nraud bearing npog nres tuag, bearing cover fastened mus rau lub tes tsho bearing los yog kawg cover.
5 、 Kev xaiv ntawm lub cev muaj zog bearing hom
Thaum lub load nqa los ntawm lub cev muaj zog tsis loj, sib sib zog nqus groove pob bearings feem ntau yog siv; thiab raws li qhov yuav tsum tau ua ntawm cov kev ua haujlwm tiag tiag, rau kev poob siab, nrog rau cov khoom loj dua, cov cylindrical cov menyuam bearings yuav tsum tau siv nyob rau hauv axial kawg ntawm lub cev muaj zog, piv nrog tib qhov loj ntawm qhov sib sib zog nqus groove pob bearings, cylindrical roller. bearings radial bearing muaj peev xwm nce 1.5-3 zaug, rigidity thiab poob siab kuj zoo dua. Sib sib zog nqus groove pob bearings bearing radial quab yuam tshaj cylindrical cov menyuam bearings tsis muaj zog, tab sis muaj peev xwm nqa tau ib tug npaum li cas ntawm axial quab yuam, thaum cylindrical roller bearings tsis tuaj yeem nqa axial quab yuam. Nyob rau hauv kev pom ntawm qhov sib sib zog nqus groove pob bearings thiab cylindrical roller bearings structural yam ntxwv, rau qhov yuav tsum tau configure cylindrical roller bearings rau lub cev muaj zog, yuav tsum tau configured siv ib tug sib tov hom, uas yog, yuav tsum muaj tsawg kawg yog ib tug sib sib zog nqus groove pob bearings. nrog nws siv.
Lub zog ntawm high voltage motors yog feem ntau loj, thiaj li yuav ua tau raws li qhov hnyav load thiab me me axial runout tswj, feem ntau nyob rau hauv raws li tus qauv configuration ntawm peb-bearing qauv. Txhawm rau txhim kho cov kabmob muaj peev xwm thiab kev pabcuam lub neej ntawm axial extension kawg kabmob, nyob rau hauv axial extension kawg nrog ib txheej ntawm cylindrical cov menyuam bearings thiab ib txheej sib sib zog nqus groove pob bearings ib sab, cylindrical cov menyuam bearings rau dais radial loads, thiab sib sib zog nqus groove pob bearings rau qhov chaw bearing axis, tsuas yog dais lub axial loads (thiab yog li qhov sib sib zog nqus groove pob bearing txheej nplhaib thiab bearing tes tsho radial feem ntau tawm ib qho kev tshem tawm); Lwm qhov kawg ntawm lub cev muaj zog raws li qhov xav tau tiag tiag los xaiv qhov sib sib zog nqus groove pob bearings, yog tias tsim nyog, koj tuaj yeem ua tau Lwm qhov kawg ntawm lub cev muaj peev xwm xaiv qhov sib sib zog nqus groove pob bearings raws li qhov xav tau tiag tiag, thiab cylindrical roller bearings tuaj yeem ua tau. xaiv yog tias tsim nyog.
Txhawm rau tiv thaiv cov bearings los ntawm kev khiav haujlwm ntawm lub cev muaj zog, lub nplhaib sab nraud thiab cov kabmob hauv chav, cov kabmob puab lub nplhaib thiab cov ncej yuav tsum xaiv qhov tsim nyog haum; Txawm hais tias nws yog axial kawg ntawm cov khoom siv bearing, lossis tsis yog axial kawg ntawm cov kabmob, yog cov qauv labyrinthine, thiab kev sib khi nrog lub nplhaib sib khi, tsis yog los tiv thaiv chav bearing ntawm cov roj lubricating rau sab hauv lub cev, kev puas tsuaj rau lub coil rwb thaiv tsev, tab sis kuj tiv thaiv sab nraud ntawm cov plua plav lossis dej rau hauv chav bearing, kom cov bearings huv si. Nws tseem tiv thaiv cov plua plav sab nraud lossis dej nkag mus rau hauv cov kabmob thiab ua kom cov kabmob huv si.
Lub high voltage lub cev muaj zog bearing system yuav tsum tau nruab nrog roj filling thiab tso cov kav dej los pab txhawb kev hloov cov roj, thiab tuaj yeem paub tias tsis nres refueling lossis ntws.
