Lub suab nrov zoo li cas rau lub cev muaj zog bearings?
Lub cev muaj zog bearing suab nrov yeej ib txwm yog ib qho teeb meem uas teeb meem ntau engineers. Raws li tau hais nyob rau hauv tsab xov xwm dhau los, lub suab nrov ntawm lub cev muaj zog bearings tsis tuaj yeem piav qhia hauv cov lus, yog li nws feem ntau ua teeb meem rau cov kws kho tsheb hauv kev txiav txim.
Txawm li cas los xij, tom qab lub sij hawm ntev ntawm kev xyaum ntawm qhov chaw, ua ke nrog kev txawj ntse thiab kev tsom xam ntawm kev paub txog lub cev muaj zog, ntau qhov kev txiav txim siab tseem ceeb ntawm qhov chaw yuav tau txais. Piv txwv li, hom "suab nrov" yog "ib txwm suab nrov" ntawm cov kabmob.
Puas muaj bearings tsis muaj "suab nrov"?
Cov neeg feem ntau nug yuav ua li cas tshem tawm lub suab nrov ntawm bearings. Lo lus teb rau lo lus nug no yog tias nws yog tsis yooj yim sua kom tshem tawm tag nrho nws. Vim tias kev ua haujlwm ntawm cov kabmob nws tus kheej yuav twv yuav raug hu muaj qee qhov "suab nrov". Tau kawg, qhov no feem ntau yog hais txog lub xeev ntawm cov kabmob thaum nws ua haujlwm ib txwm, suav nrog:
Puas muaj bearings tsis muaj "suab nrov"? Kev sib tsoo ntawm dov cov ntsiab lus thiab cov kev sib tw hauv cheeb tsam tsis thauj khoom 01
Cov txheej txheem dov ntawm cov kabmob khiav hauv cov kabmob raceway. Thaum cov khoom dov khiav hauv qhov chaw tsis muaj kev thauj khoom, cov khoom dov yuav sib tsoo nrog cov kev sib tw hauv cov kev taw qhia radial lossis axial. Qhov no yog vim hais tias cov khoom dov nws tus kheej tawm ntawm qhov chaw thauj khoom thiab muaj qee qhov kev nrawm nrawm. Nyob rau tib lub sijhawm, cov khoom dov muaj qee qhov quab yuam centrifugal. Thaum nws tig ib ncig ntawm lub axis, nws yuav sib tsoo nrog txoj kev sib tw, yog li tsim suab nrov. Tshwj xeeb tshaj yog nyob rau hauv cheeb tsam uas tsis yog-loading, thaum residual clearance tshwm sim, xws li kev sib tsoo suab nrov yog tshwj xeeb tshaj yog pom tseeb.
Puas muaj bearings tsis muaj "suab nrov"? Kev sib tsoo ntawm dov lub ntsiab thiab tawb 02
Lub luag haujlwm tseem ceeb ntawm lub tawb yog coj kev ua haujlwm ntawm cov khoom siv dov. Kev sib tsoo ntawm lub caij dov thiab lub tawb kuj yog ib qho ntawm cov suab nrov. Xws li kev sib tsoo muaj xws li circumferential, radial, thiab tej zaum axial. Los ntawm qhov kev xav ntawm lub xeev cov lus tsa suab, nws suav nrog kev sib tsoo thaum lub caij dov nquag thawb lub tawb hauv thaj chaw thauj khoom; kev sib tsoo thaum lub tawb thawb lub dov lub caij nyob rau hauv qhov chaw tsis muaj load. Kev sib tsoo ntawm lub dov lub caij thiab lub tawb nyob rau hauv lub radial kev taw qhia vim lub centrifugal quab yuam. Vim muaj kev cuam tshuam, kev sib tsoo ntawm cov khoom dov thiab lub tawb thaum lub sij hawm axial txav, thiab lwm yam. Puas muaj bearings tsis muaj "suab nrov"? Rolling element stirring grease 03
Thaum cov kabmob tau ntim nrog roj, kev ua haujlwm ntawm cov khoom dov dov cov roj. Qhov kev nplawm no kuj yuav tsim cov suab nrov sib xws.
Puas muaj bearings tsis muaj "suab nrov"? Sliding kev sib txhuam ntawm dov cov ntsiab lus nyob rau hauv thiab tawm ntawm raceway 04
Muaj qee qhov zawv zawg kev sib txhuam ntawm cov khoom dov thiab txoj kev sib tw thaum nws nkag mus rau hauv qhov chaw thauj khoom. Tej zaum kuj yuav muaj qee qhov kev sib txhuam zawv zawg thaum nws tawm ntawm qhov chaw thauj khoom.
Puas muaj bearings tsis muaj "suab nrov"? Lwm yam kev txav hauv cov kabmob 05
Kev sib txhuam ntawm cov kabmob di ncauj nrog cov ntsaws ruaj ruaj tuaj yeem ua suab nrov.
Hauv cov ntsiab lus, nws tsis yog qhov nyuaj kom pom tias cov dov bearings khiav hauv ib txwm muaj yuav ua rau muaj qee qhov "suab nrov". Yog li, cov lus teb rau lo lus nug qhib yog: Rau dov bearings, lub hauv paus "ib txwm suab" yog tsis yooj yim sua kom tshem tawm.
Yog li, dab tsi yog lub suab ntawm lub cev muaj zog bearings?
Los ntawm kev txheeb xyuas yav dhau los, peb tuaj yeem pom tias cov lus tsa suab no tsim suab nrov vim kev sib tsoo thiab kev sib txhuam. Rau ib qho kev coj tus kheej thiab tsim nyog, nws tsis yog qhov nyuaj kom pom tias cov suab nrov no cuam tshuam nrog kev ceev. Piv txwv li, kev sib txhuam thaum lub caij dov nkag mus thiab tawm ntawm qhov chaw thauj khoom, kev sib tsoo ntawm cov khoom sib tsoo nrog lub tawb sab hauv thiab sab nraud ntawm qhov chaw thauj khoom, kev sib txhuam ntawm cov roj, kev sib txhuam ntawm lub foob di ncauj, thiab lwm yam, yuav hloov nrog. kev hloov ceev. Thaum lub cev muaj zog nyob ntawm qhov nrawm, cov kev txav no yuav tsum nyob hauv lub xeev ruaj khov. Yog li ntawd, lub suab nrov nrov ntawm lub sijhawm no yuav tsum yog lub suab ruaj khov thiab zoo ib yam. Los ntawm qhov no peb tuaj yeem suav tau tias lub suab nrov ntawm cov kabmob yuav tsum muaj cov yam ntxwv tseem ceeb, uas yog, ruaj khov thiab tsis sib xws. Lub stability thiab uniformity hais ntawm no tsis yog ib tug nruam suab. Vim tias muaj ntau lub xeev cov lus tsa suab, xws li kev sib tsoo, tshwm sim ib qho tom qab, yog li cov suab no yog ib lub suab me me uas ruaj khov. Ntawm chav kawm, qee lub suab txuas ntxiv kuj suav nrog, xws li lub suab ntawm kev sib tsoo. Hauv kev ua haujlwm tiag tiag, xws li thaum muaj qee qhov cuam tshuam, lub suab nrov kuj yuav tshwm sim kom ruaj khov thiab zoo ib yam rau qee yam. Txawm li cas los xij, hom suab nrov no feem ntau tsis zoo li qhov zaus uas cov kabmob yuav tsum muaj. Yog li ntawd, thaum txiav txim siab coj lub suab nrov ntawm qhov chaw, ntxiv rau kev ruaj ntseg thiab zoo ib yam, nws yog ib qho tsim nyog yuav tsum tau ntxiv ntau zaus yam tsis muaj qhov txawv txav (kev hnov ​​​​lus).
