Xam cov kabmob Lub neej: Cov kabmob Loads & Ceev

Cov kabmob lub neej feem ntau yog ntsuas siv L10 lossis L10h suav. Kev suav yog qhov tseem ceeb ntawm kev hloov pauv ntawm tus kheej lub neej. Ib tug kabmob L10 lub neej raws li tau hais los ntawm ISO thiab ABMA cov qauv yog raws li lub neej uas 90% ntawm ib pawg loj ntawm cov kabmob zoo ib yam yuav tau txais lossis ntau dua. Nyob rau hauv ib tug luv luv, ib tug xam nyob rau hauv ntev npaum li cas 90% ntawm cov bearings yuav nyob rau hauv ib daim ntawv thov.

Nkag siab L10 Cov Menyuam Bearing Lub Neej

L10h = Basic rating life in hours

P = Dynamic sib npaug load

C = Basic dynamic load ntsuam xyuas

n = Rotational ceev

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

L10 - yooj yim load rating-revolutions

L10s - qhov ntsuas qhov nruab nrab ntawm qhov deb (KM)

 

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

Xam & Nkag Siab Txog Lub Neej

P = Combined Load (Dynamic Equivalent Load)

X = Radial load factor

Y = Axial load factor

Fr = Radial load

Fa = Axial load

Daim ntawv ceeb toom tias L10 Life Calculation tsis xav txog qhov kub thiab txias, lubrication thiab ib lub tswv yim ntawm lwm yam tseem ceeb tseem ceeb heev rau kev ua tiav daim ntawv thov tsim lub neej. Kev kho kom raug, tuav, tu thiab kev teeb tsa yog txhua yam xav tau yooj yim. Qhov no yog vim li cas nws yog qhov nyuaj heev los twv seb cov kabmob qaug zog thiab yog vim li cas tsawg dua 10% ntawm cov kabmob puas tau ntsib lossis tshaj lawv lub neej qaug zog.

Yuav Ua Li Cas Txiav Txim Siab Kev Pabcuam Lub Neej?

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