Lub cev muaj zog tsau kawg cov kabmob
Tsau-kawg bearings siv cov radial bearings uas muaj peev xwm ntawm cov kabmob sib xyaw ua ke (radial thiab axial) cov khoom thauj.Cov kabmob no suav nrog: sib sib zog nqus zaws pob bearings, ob chav kab lossis paired ib kab angular hu npas kabmob, cov kabmob sib luag nrog cov kabmob, kheej kheej cov menyuam cov kabmob, kev sib xyaw tapered cov menyuam bearings, NUP hom cylindrical menyuam bearings lossis NJ hom cylindrical menyuam bearings nrog HJ lub nplhaib Cov.
Rau kev xaiv ntawm lub cev muaj zog cov kev txhawb nqa kev ruaj ntseg ruaj ruaj kawg (lub cev muaj zog ruaj khov rau luv luv), cov hauv qab no yuav tsum txiav txim siab:
(1) Kev tswj qhov tseeb ntawm cov khoom uas raug rub tawm;
(2) qhov xwm txheej load ntawm lub tshuab tsav;
(3) Cov kabmob lossis cov kabmob sib txuas ua ke yuav tsum muaj peev xwm tiv thaiv qee qhov kev quab yuam axial.
Ua ke nrog cov saum toj no peb qhov ntawm cov qauv tsim, sib sib zog nqus groove pob bearings yog feem ntau siv los ua thawj qhov kev xaiv rau kev ruaj khov kawg ntawm cov kabmob me thiab nruab nrab.
Sib sib zog nqus npoo pob bearings yog cov khoom siv yob kabmob siv feem ntau.Thaum sib sib zog nqus groove pob tau siv, cov qauv ntawm lub cev muaj zog txhawb nqa lub cev yog yooj yim heev thiab yooj yim rau kev tswj.Kev sib sib zog nqus zaws pob cov kabmob yog feem ntau siv los tiv thaiv cov radial load, tab sis thaum cov radial tshem tawm ntawm cov kabmob tau nce, nws muaj cov yam ntxwv ntawm angular hu rau cov kabmob pob thiab tuaj yeem dais radial thiab axial ua ke load.Thaum tus ceev yog qhov siab thiab lub pob thawb lub pob tsis haum, nws kuj tseem siv tau los ua tus thauj khoom axial ntshiab.Piv nrog rau lwm hom bearings nrog qhov tshwj xeeb thiab qhov loj me raws li qhov sib sib zog nqus groove pob bearings, cov kabmob no muaj qhov zoo ntawm kev sib txhuam me me thiab qhov siab ceev, thiab qhov tsis zoo yog tsis cuam tshuam thiab tsis haum rau lub nra hnyav.
Thaum lub sib sib zog nqus groove pob kabmob tau tsa ntawm tus ncej, radial haum nyob rau hauv ob qho kev qhia ntawm tus ncej lossis vaj tsev tuaj yeem raug txwv nyob rau hauv cov axial clearance ntau ntawm cov kabmob.Hauv cov kev taw qhia radial, kev cuam tshuam haum siv ntawm kev coj tus kheej thiab tus ncej, thiab kev cuam tshuam me me yog siv ntawm cov kabmob thiab kawg npog cov kabmob chav lossis lub plhaub. Lub hom phiaj ntawm kev xaiv cov kev haum zoo yog kom paub tseeb tias kev ua haujlwm ntawm kev tshem tawm cov kabmob yog xoom lossis me ntsis tsis zoo thaum lub sijhawm ua haujlwm ntawm lub cev muaj zog, kom ua tiav kev ua haujlwm ntawm cov kabmob zoo dua.Hauv cov kev taw qhia axial, txoj haujlwm axial ntawm kev muab tso rau cov kabmob thiab cov khoom sib txuam yuav tsum txiav txim siab ua ke nrog qhov xwm txheej tshwj xeeb ntawm ntab ntab ntaws qhov kawg.Cov kabmob sab hauv lub nplhaib yog qhov txwv los ntawm cov kabmob txoj haujlwm txwv cov kauj ruam (lub cev lub xub pwg) thiab cov kabmob tuav lub nplhaib rau ntawm tus ncej, thiab cov kabmob sab nraud ntiv nplhaib yog tswj los ntawm txoj kev sib zam ntawm cov kabmob thiab cov kabmob ua ke, qhov siab ntawm sab hauv thiab sab nraud npog ntawm cov kabmob thiab qhov ntev ntawm cov kabmob ua ke.
Lub cev muaj zog floating xaus cov kabmob
Lub ntab kawg ntawm lub cev muaj zog kuj tseem hu ua qhov xaus dawb, uas yog ntu ntawm qhov chaw tsau;Feem ntau, lub ntab ntab ntab ntaws tau raug xaiv ntawm qhov tsis tsav thaum kawg, tab sis nyob rau hauv rooj plaub uas lub cev muaj zog cov khoom yuav tsum tau siab, thiab cov axial haum raws qhov xav tau nrog cov khoom siv thauj khoom tsis yog siab heev, kawg ntab yuav xaiv nyob rau ntawm tsav tsheb kawg.
Thaum lub cev muaj zog txhawb nqa lub cev yog ob chav sau thiab ob chav coj cov qauv, thaum cov radial load yuav tsum loj, kev tsav tsheb kawg tseem siv los ua qhov kawg ntab. Tshwj xeeb tshaj yog rau cov hluav taws xob muaj hluav taws xob tsawg thiab lub zog hluav taws xob muaj zog, lub tshuab cylindrical cov kabmob ntawm cov ntab kawg tuaj yeem ua tau raws li qhov yuav tsum tau ntawm loj radial load.
Cylindrical cov menyuam cov menyuam thiab cov kev sib tw rau cov kab sib txuas lossis kho cov kab sib txuas, radial bearing muaj peev xwm loj, ntau haum rau cov kabmob hnyav thiab muaj feem cuam tshuam, lub nplhaib sab hauv lossis sab nraud tuaj yeem sib cais, yooj yim rau nruab thiab rhuav tshem.Qhov no cov kabmob ntawm cov kabmob muaj cov kev sib txhuam me me thiab tsim nyog rau kev kub ceev thiab huab nrawm ze rau qhov sib sib zog nqus groove pob bearings.Hom N thiab NU cylindrical roller bearings siv feem ntau hauv lub cev muaj zog. Cov nplhaib puab thiab sab nraud ntawm cov kabmob tuaj yeem txav mus axially. Lawv tuaj yeem hloov kho qhov kev hloov pauv ntawm qhov chaw txheeb ze ntawm tus ncej thiab lub plhaub tshwm sim los ntawm thermal nthuav lossis teeb tsa yuam kev, thiab tuaj yeem siv ua kev txhawb nqa pub dawb.Txawm li cas los xij, kev coj tus kheej tau ua cov haujlwm siab dua rau kev ua haujlwm los yog cov kabmob ua ke lub qhov, thiab qhov sib txawv ntawm cov ntiv nplhaib sab hauv thiab sab nrauv tom qab kev teeb tsa kabmob yuav tsum raug tswj nruj kom tsis txhob muaj qhov cuam tshuam ntawm kev sib cuag.
Piv nrog rau cov kabmob kawg ruaj khov, txhawm rau ua kom tau raws cov axial hloov chaw ntawm lub rotor ib feem thaum lub sijhawm ua haujlwm ntawm lub cev muaj zog, txoj haujlwm axial tshem tawm ntawm lub nplhaib sab nraud ntawm cov kabmob thiab sab hauv thiab sab nraud ntawm cov kabmob tau sib txawv raws cov kabmob sib txawv xaiv.
(1) Thaum ntab ntaws kawg adopts cov kabmob nrog sib cais sab hauv thiab sab nraud, qhov xaus ruaj ntseg yog xaiv ntawm qhov tsis tsav ntawm qhov kawg rau ob-kabmob qauv tsav;Tsis muaj qhov tseeb ntawm lub nplhaib sab nraud ntawm lub ruaj ruaj sab kawg thiab ntab ntaws kawg cov kabmob thiab sab hauv thiab sab nraud ntawm cov kabmob.
(2) thaum ntab nthwv kawg ntawm cov kabmob tsis muaj qhov cuam tshuam, uas yog, me me thiab nruab nrab lub cev muaj zog muaj feem ntau ntawm ob qho kawg ntawm lub pob kabmob qauv, nyob rau hauv kev saib ntawm qhov cuam tshuam rau kev teeb tsa raug qhov tseeb ntawm cov cuab yeej tsav, tsav tsheb kawg yog lub tsau tas, lub nplhaib sab hauv ntawm cov kabmob kawg ntab yuav tsum tau txwv, thiab txoj kab nrig ntawm lub nplhaib sab nraud thiab sab hauv thiab sab nraud ntawm cov kabmob sab laug;Nyob rau tib lub sijhawm, txhawm rau kom paub meej txoj xov axial haum chaw nyob rau hauv kev ua haujlwm ntawm lub cev muaj zog, radial haum nruab nrab ntawm lub nplhaib sab nraud ntawm lub kabmob thiab cov kabmob ua ke tsis yooj yim kom nruj dhau.
Kev teeb tsa cov kabmob tiag tiag yuav tsum sib phim nrog kev ua haujlwm ntawm lub cev muaj zog, suav nrog cov kev txwv tshwj xeeb xws li kev tshem tawm, kev tiv thaiv thaum tshav kub kub, qhov tseeb, thiab qhov ntsuas radial sib txheeb ntawm cov kabmob thiab cov kabmob ua ke hauv kev xaiv ntawm lub cev muaj zog.
