Cov kabmob twg zoo dua, C3 lossis C4?

Cov tub ntxhais sib txawv ntawm C3 thiab C4 bearings nyob ntawm qhov loj ntawm radial clearance ntawm cov bearings, nrog C4 bearings muaj clearance loj dua bearings.

Tus nqi Clearance thiab Grouping ntawm Bearings

C3 bearing: Lub radial clearance yog 0.013mm txog 0.028mmsib sib zog nqus groove pob bearingsua piv txwv), thiab qhov kev tshem tawm yog ntau dua li cov qauv pawg (C0), koom nrog pawg tshem tawm loj.
C4 bearing: Tus thawj radial clearance yog 0.023mm mus rau loj, thiab qhov clearance yog ntxiv ntxiv piv rau C3, ces C4 yog loj nyob rau hauv lub clearance pab pawg neeg.

Daim ntawv thov

C3 bearings: lawv siv tau rau ib puag ncig nrog kev kub ceev thiab kev co, xws li siab -ceev motors lossis cov xwm txheej nrog thermal expansion. Thaum lub sijhawm ua haujlwm, cov kabmob no tuaj yeem txo qis kev hnav los ntawm kev ua kom pom tseeb kom tswj tau qhov kev ua haujlwm zoo ntawm cov khoom siv.
C4 bearings: lawv tau siv rau kev ua haujlwm nrog kev vibrations hnyav dua, ntau dua kev teeb tsa yuam kev uas yuav tsum tau them nyiaj, lossis kev nthuav dav thermal, xws li cov tshuab hnyav lossis siab - cov khoom siv kub, tab sis tej zaum yuav txi qee qhov raug thiab lub neej ntev.

Clearance Grouping System Ntawm Bearings

Lub radial clearance ntawm bearings yog muab faib ua 6 pawg (C1, C2, C0, C3, C4, C5 thiab clearance nce nyob rau hauv sequence. C0 yog tus qauv pab pawg neeg, thiab annotations feem ntau yog tshem tawm; C3 thiab C4 yog ob qho tib si loj clearance pab pawg neeg, thiab kev xaiv yuav tsum tau raws li nyob rau hauv tiag tiag vibration, ceev, thiab kub tej yam kev mob.

Yuav ua li cas xaiv C3 lossis C4 bearings

Thaum peb xaiv bearings, cov hauv qab no yuav tsum tau txiav txim siab:

1. Kev ua haujlwm: Peb yuav tsum paub qhov chaw ua haujlwm thiab kev ua haujlwm ntawm cov khoom siv, ces xaiv cov khoom tsim nyog. Yog tias cov cuab yeej ua haujlwm hauv qhov siab -ceev, siab vibration ib puag ncig, C3 bearings yog qhov kev xaiv zoo dua; Yog tias cov cuab yeej xav tau los tiv thaiv kev vibrations thiab cuam tshuam, C4 bearings yuav tsum raug xaiv.

2. Kev pab lub neej: xav txog kev pabcuam lub neej ntawm cov kabmob, nws yog ib qho tsim nyog yuav tau xaiv hom kabmob raws li kev saib xyuas thiab hloov cov khoom siv. Feem ntau, C3 bearings muaj lub neej ua haujlwm ntev thiab tsim nyog rau cov xwm txheej uas yuav tsum tau ua haujlwm ntev - lub sijhawm ruaj khov; C4 bearings yog tsim nyog rau luv luv -lub sij hawm, siab- siv zog ua hauj lwm scenarios.

Hauv cov ntsiab lus, muaj qhov sib txawv tseem ceeb ntawm C3 thiab C4 bearings nyob rau hauv cov nqe lus ntawm radial clearance, daim ntawv thov scenarios, thiab kev pab cuam lub neej. Thaum xaiv, qhov kev xav tau tiag tiag thiab qhov chaw ua haujlwm ntawm cov khoom siv yuav tsum tau txiav txim siab los xyuas kom meej qhov kev xaiv ntawm cov kabmob tsim nyog.Yog tias koj tsis paub nws zoo heev, thovtiv tauj pebmus kawm ntxiv txog lawv.
