Bearing technology hloov li cas?

Nyob rau hauv ob peb lub xyoo dhau los, tus tsim ntawm bearings tau nce siab coj cov khoom siv tshiab, cov txheej txheem lubrication siab heev thiab kev soj ntsuam hauv computer..

Bearings yog siv nyob rau hauv tag nrho cov hom ntawm rotating machinery. Los ntawm kev tiv thaiv thiab cov cuab yeej siv dav hlau mus rau cov khoom noj khoom haus thiab dej haus, qhov kev thov rau cov khoom no tau nce. Qhov tseem ceeb, cov kws tsim qauv tsim tau xav tau ntau dua, sib zog thiab ntau cov kev daws teeb meem kom txaus siab txawm tias feem ntau qhov kev sim ntawm ib puag ncig.

 

Khoom siv science

Txo kev sib txhuam yog qhov tseem ceeb ntawm kev tshawb fawb rau cov neeg tsim khoom. Ntau yam cuam tshuam rau kev sib txhuam xws li qhov ntev ntev, qhov ua tiav, qhov kub thiab txias, kev ua haujlwm siab thiab ceev. Kev nce qib tseem ceeb tau ua hauv cov kabmob steel ntau xyoo. Niaj hnub no, ultra-clean bearing steels muaj tsawg dua thiab me me uas tsis yog-hlau, muab cov pob bearings ntau dua tiv thaiv kev qaug zog.

 

Niaj hnub nimno steel-ua thiab de-gassing cov tswv yim tsim cov hlau nrog qis qis ntawm oxides, sulphides thiab lwm cov roj yaj thaum cov txheej txheem hardening zoo dua tsim cov hlau hnyav dua thiab hnav-resistant. Kev nce qib hauv kev tsim cov tshuab ua kom cov neeg tsim khoom ntawm precision bearings kom muaj kev sib raug zoo nyob rau hauv cov kabmob cov kabmob thiab tsim cov khoom siv polished ntau dua, tag nrho cov uas txo kev sib txhuam thiab txhim kho lub neej.

 

Tshiab 400-qib stainless hlau (X65Cr13) tau tsim los txhim kho cov kabmob suab nrov nrog rau cov hlau nitrogen siab kom muaj zog dua corrosion. Rau ib puag ncig corrosive los yog kub heev, cov neeg muas zaub tam sim no tuaj yeem xaiv los ntawm ntau yam ntawm 316-qib stainless hlau bearings, tag nrho cov kabmob ceramic lossis yas bearings ua los ntawm acetal resin, PEEK, PVDF lossis PTFE. Raws li 3D luam ntawv tau siv ntau dua, thiab yog li ntawd tus nqi ntau dua, peb pom muaj peev xwm ntau ntxiv rau kev tsim cov khoom tsis zoo ntawm cov kabmob me me, ib yam dab tsi uas yuav pab tau rau cov khoom ntim tsawg ntawm cov kws tshwj xeeb bearings.

 

Lubrication

 

Lubrication tej zaum yuav tau garnered feem ntau mloog. Nrog 13% ntawm cov kabmob tsis ua haujlwm vim yog lub luag haujlwm lubrication, bearing lubrication yog qhov chaw nrawm nrawm ntawm kev tshawb fawb, txhawb nqa los ntawm kev kawm thiab kev lag luam ib yam nkaus. Tam sim no muaj ntau yam tshwj xeeb lubricants ua tsaug rau ib tug xov tooj ntawm yam tseem ceeb: ib tug dav ntau yam ntawm cov zoo hluavtaws roj, ib tug ntau dua xaiv ntawm thickeners siv nyob rau hauv roj siv thiab ntau ntau yam ntawm lubricant additives los muab, piv txwv li, ntau dua load peev xwm. los yog ntau dua corrosion kuj. Cov neeg siv khoom tuaj yeem hais qhia cov roj uas tsis muaj suab nrov, cov roj roj siab ceev, cov roj nplua nyeem rau qhov kub thiab txias, cov roj tsis muaj dej tsis zoo thiab cov tshuaj tiv thaiv, cov roj nplua nyeem siab thiab cov roj huv huv.

 

Kev tsom xam hauv computer

 

Lwm qhov chaw uas cov kabmob kev lag luam tau ua haujlwm zoo yog los ntawm kev siv cov kabmob simulation software. Tam sim no, kev ua tau zoo, lub neej thiab kev ntseeg siab tuaj yeem txuas ntxiv mus dhau qhov uas tau ua tiav ib xyoo caum dhau los yam tsis tau ua qhov kev sim siv sij hawm kim lossis kev sim teb. Advanced, kev tsom xam ntawm dov lub caij bearings tuaj yeem muab kev pom tsis zoo rau kev ua haujlwm ntawm cov kabmob, ua kom pom cov kabmob xaiv tau zoo thiab zam kev tsis ua haujlwm ntxov ntxov.

 

Txoj kev ua neej qaug zog siab heev tuaj yeem tso cai rau kev kwv yees qhov tseeb ntawm lub caij thiab kev sib tw kev nyuaj siab, kev sib cuag tav, ntug kev ntxhov siab, thiab kev sib cuag truncation. Lawv kuj tso cai rau tag nrho cov system deflection, load tsom xam thiab bearing misalignment tsom xam. Qhov no yuav muab cov ntaub ntawv engineers los hloov kho cov kabmob tsim kom haum rau cov kev ntxhov siab uas tshwm sim los ntawm cov ntawv thov tshwj xeeb.

 

Lwm qhov zoo dua yog tias simulation software tuaj yeem txo cov sijhawm thiab cov peev txheej siv rau theem kev sim. Qhov no tsis yog tsuas yog ua kom ceev cov txheej txheem kev txhim kho tab sis kuj txo cov nqi hauv cov txheej txheem.

 

Nws yog qhov tseeb tias cov ntaub ntawv tshiab kev tsim kho nrog rau cov cuab yeej ua haujlwm siab tshaj plaws yuav muab cov kws ua haujlwm paub txog kev tsim thiab xaiv cov bearings rau kev ua tau zoo thiab ua haujlwm ntev, ua ib feem ntawm tag nrho cov qauv. Kev tshawb fawb txuas ntxiv thiab kev txhim kho hauv cov haujlwm no yuav yog qhov tseem ceeb hauv kev ua kom cov kabmob txuas ntxiv mus thawb cov ciam teb rau xyoo tom ntej.
