Cov kabmob kub siab

Cov kabmob kub siab yog dab tsi?

Qhov hu ua high-temperature bearing txhais tau hais tias qhov kub ua haujlwm siab dua li qhov kub ntawm cov bearing ib txwm muaj, thiab cov bearing siv ntawm qhov kub ua haujlwm dav dav ntau dua 150° hu ua kev coj ua kub siab.

 

Cov yam ntxwv ntawm cov bearings kub siab:

 

1. Siv tau lubrication tas mus li, tsis muaj roj ntxiv thaum siv.

 

2. Tus nqi tsim nyog, qhov zoo yog ntau dua li ntawm cov bearings ib txwm muaj.

 

3. Nws tau yeej kev ntseeg siab ntawm peb cov neeg siv khoom nrog lub neej ua haujlwm ntev.

 

4. Cov kabmob kub kub siv dav hauv metallurgy, kilns, iav, blast furnaces, painting khoom siv thiab lwm yam machinery nyob rau hauv high temperature operations.

 

Cov kabmob kub siab feem ntau yog siv rau hauv cov cav dav hlau aviation, cov roj turbines, cov tshuab nuclear reactor, X-ray tube tungsten discs, cov tsheb ceev ceev, cov foob pob hluav taws, thiab cov dav hlau.

 

Kev teeb tsa cov bearings kub siab

Ntxiv rau, yog tias muaj kev nias rau ib sab ntawm lub nplhaib (xws li lub nplhaib sab nraud), thiab sab tod ntawm lub nplhaib (xws li lub nplhaib sab hauv) raug nias rau hauv nws los ntawm lub ntsiab lus dov, qhov no feem ntau yuav ua rau muaj kev sib tsoo lossis kev puas tsuaj ntawm qhov chaw dov, thiab nws yuav tsum tsis txhob siv, tshwj xeeb tshaj yog tias cov kabmob uas tsis sib cais tau teeb tsa rau ntawm tus ncej thiab lub tsev kabmob tib lub sijhawm.

 

Thaum lub sijhawm ua kom sov thiab txhim kho cov kabmob, nws yog qhov tsim nyog kom nkag siab txog qhov kub thiab txias ntawm cov kabmob kub siab nyob rau hauv cov kabmob kub sib txawv.

 

Haum ntawmcov kabmob kub siab

1. Kev cuam tshuam

 

Lub nplhaib sab hauv thiab lub nplhaib sab nraud ntawm lub dov khoom raug tsau rau ntawm tus ncej lossis lub thawv bearing, thiab thaum nws raug thauj khoom, lub nplhaib thiab tus ncej lossis lub thawv bearing tsis muaj kev txav mus los radial, axial thiab rotational, thiab qhov kev txav mus los no yuav ua rau muaj kev sib txhuam, kev sib txhuam corrosion lossis kev sib txhuam tawg ntawm qhov chaw mating, yog li ua rau muaj kev puas tsuaj rau tus ncej thiab lub thawv bearing, thiab tom qab ntawd cov hmoov txhuam tau sib xyaw rau hauv tus ncej, uas ua rau kev ua haujlwm tsis zoo, cua sov tsis zoo lossis kev co.

 

Raws li txoj kev ruaj khov bearing, nws yog qhov zoo tshaj plaws kom tawm qhov cuam tshuam ntawm qhov sib phim ntawm lub nplhaib thiab lub ncej lossis lub tsev bearing, thiab qhov haum zoo li qub yog qhov zoo tshaj plaws, yog li ntawd lub nra ntawm lub nplhaib nyias-phab ntsa tau faib sib npaug ntawm qhov ncig yam tsis cuam tshuam rau lub peev xwm thauj khoom ntawm cov bearing.

 

Txawm li cas los xij, ntxiv rau qhov tsis yooj yim ntawm kev txuas thiab dismounting lub bearing, nws tsis tuaj yeem siv rau txhua qhov xwm txheej thaum lub bearing raug sib cais thiab tsis tuaj yeem txav mus rau axially thaum lub bearing raug sib cais thaum lub bearing siv.

 

2. Kev xaiv qhov haum

 

Kev xaiv qhov haum feem ntau yog ua raws li cov hauv paus ntsiab lus hauv qab no:

 

(1) Raws li qhov kev taw qhia thiab qhov xwm txheej ntawm lub nra hnyav ua rau ntawm tus kabmob thiab sab twg ntawm lub nplhaib sab hauv thiab sab nraud tig, lub nra hnyav uas nqa los ntawm txhua lub nplhaib tuaj yeem muab faib ua lub nra hnyav rotary, lub nra hnyav static, lossis lub nra hnyav tsis yog kev taw qhia, lub nplhaib uas dais lub nra hnyav tig thiab lub nra hnyav tsis yog kev taw qhia yuav tsum siv qhov haum zoo li qub (cuam tshuam haum), lub nplhaib uas dais lub nra hnyav zoo li qub tuaj yeem siv qhov hloov pauv lossis dynamic haum (clearance haum), thaum lub nra hnyav bearing loj lossis dais kev co thiab kev poob siab, qhov cuam tshuam yuav tsum tau nce, thaum lub qhov hollow, lub thawv bearing nyias-walled lossis lub teeb alloy thiab lub thawv yas bearing siv, Nws tseem tsim nyog los nce qhov ntau ntawm kev cuam tshuam.

 

(2) Thaum nws xav tau kom tswj tau qhov kev sib hloov siab, yuav tsum siv cov bearings siab, thiab qhov tseeb ntawm cov ncej thiab cov thawv bearing yuav tsum tau txhim kho, kom tsis txhob muaj kev cuam tshuam ntau dhau, yog tias qhov kev cuam tshuam loj dhau, qhov tseeb geometric ntawm cov bearing lossis lub thawv qag tuaj yeem cuam tshuam rau geometry ntawm lub nplhaib bearing, yog li ua rau qhov tseeb ntawm kev sib hloov ntawm cov bearing puas tsuaj, yog tias cov nplhaib sab hauv thiab sab nraud ntawm cov bearings tsis sib cais (xws li cov bearings pob sib sib zog nqus) yog qhov haum zoo li qub, ces qhov kev teeb tsa thiab kev sib cais ntawm cov bearing tsis yooj yim heev, thiab nws yog qhov zoo tshaj plaws los txais yuav qhov haum dynamic ntawm ib sab ntawm lub nplhaib sab nraud.

 

3. Kev koom tes yog qhov pom zoo

 

Hais txog qhov loj ntawm lub ncej thiab qhov loj ntawm lub qhov thiab lub tsev nyob uas cov bearings tau teeb tsa, ISO283 (qhov ntev thiab qhov haum) tau raug saws los siv rau hauv cov koob metric, yog li qhov haum tau txiav txim siab raws li qhov loj ntawm lub ncej thiab qhov loj ntawm lub qhov xaiv.
