Lub neej ntawm kev dais

Xam Lub Neej Bearing: Bearing Loads & Speeds

Lub neej ntawm cov kabmob feem ntau yog ntsuas los ntawm kev siv L10 lossis L10h xam. Qhov kev xam no yog qhov sib txawv ntawm cov neej ntawm cov kabmob ib tus zuj zus. Lub neej ntawm cov kabmob L10 raws li tau txhais los ntawm ISO thiab ABMA cov qauv yog raws li lub neej uas 90% ntawm ib pawg loj ntawm cov kabmob zoo sib xws yuav ua tiav lossis tshaj qhov ntawd. Hauv kev luv luv, kev xam txog lub sijhawm ntev npaum li cas 90% ntawm cov kabmob yuav kav ntev hauv ib daim ntawv thov.

Nkag Siab Txog Lub Neej Ntawm Cov Menyuam Bearing L10

L10h = Lub neej ntsuas yooj yim hauv teev

P = Dynamic sib npaug load

C = Qhov ntsuas dynamic load yooj yim

n = Qhov ceev ntawm kev tig

p = 3 rau cov kabmob pob lossis 10/3 rau cov kabmob menyuam

L10 - qhov ntsuas qhov hnyav yooj yim-kev hloov pauv

L10s - qhov ntsuas qhov hnyav yooj yim hauv qhov deb (KM)

 

Raws li koj tuaj yeem pom los ntawm cov qauv saum toj no, txhawm rau txiav txim siab lub neej L10 ntawm ib qho kev coj ua tshwj xeeb, qhov kev siv radial thiab axial loads yog qhov xav tau nrog rau qhov ceev ntawm kev siv (RPM's). Cov ntaub ntawv thauj khoom tiag tiag ntawm daim ntawv thov raug muab tso ua ke nrog cov ntsuas kev thauj khoom ntawm cov kabmob kom paub txog qhov sib xyaw ua ke lossis Dynamic equivalent load uas xav tau los ua kom tiav qhov kev suav lub neej.

Xam thiab Nkag Siab Txog Lub Neej Ntawm Cov Bearing

P = Kev Thauj Khoom Ua Ke (Kev Thauj Khoom Sib Npaug Dynamic)

X = Qhov hnyav ntawm Radial

Y = Qhov hnyav ntawm axial

Fr = Radial load

Fa = Axial load

Nco ntsoov tias L10 Lub Neej Xam tsis xav txog qhov kub thiab txias, lubrication thiab ntau lwm yam tseem ceeb uas tseem ceeb rau kev ua tiav lub neej ntawm cov kabmob uas tau tsim. Kev kho, kev tuav, kev saib xyuas thiab kev teeb tsa kom zoo tsuas yog xav xwb. Qhov no yog vim li cas nws thiaj nyuaj heev rau kev kwv yees qhov kev qaug zog ntawm cov kabmob thiab vim li cas tsawg dua 10% ntawm cov kabmob puas tau ua tau raws li lossis tshaj lawv lub neej qaug zog uas tau xam.

Dab tsi txiav txim siab lub neej ua haujlwm ntawm Bearing?

Tam sim no koj nkag siab zoo txog yuav ua li cas xam lub neej qaug zog thiab lub sijhawm ntev ntawm cov kabmob dov, cia peb tsom mus rau lwm yam uas txiav txim siab lub neej ntev. Kev hnav thiab tsim kua muag ntuj yog qhov ua rau cov kabmob tawg feem ntau, tab sis cov kabmob kuj tseem tuaj yeem ua tsis tiav ua ntej vim qhov kub thiab txias heev, tawg, tsis muaj lubrication lossis puas tsuaj rau cov foob lossis lub tawb. Hom kev puas tsuaj ntawm cov kabmob no feem ntau yog qhov tshwm sim ntawm kev xaiv cov kabmob tsis raug, qhov tsis raug hauv kev tsim cov khoom ib puag ncig, kev teeb tsa tsis raug lossis tsis muaj kev saib xyuas thiab lubrication kom raug.
