Kev nrhiav kom muaj lub neej ntev dua, kev ceev dua, thiab kev ua haujlwm zoo dua hauv tshuab yog qhov tsis muaj kev txwv. Txawm hais tias lub geometry tseem ceeb ntawm lub pob sib sib zog nqus tseem tsis tau hloov pauv mus tas li, kev hloov pauv ntsiag to tab tom tshwm sim ntawm theem khoom siv. Cov tiam tom ntej ntawm cov bearings no tab tom txav mus dhau cov hlau ib txwm muaj, suav nrog cov khoom siv ceramic engineering siab heev, kev kho qhov chaw tshiab, thiab cov ntaub ntawv sib xyaw ua ke los rhuav tshem cov kev txwv kev ua tau zoo yav dhau los. Qhov no tsis yog kev txhim kho me ntsis xwb; nws yog kev hloov pauv paradigm rau cov ntawv thov hnyav.
Kev Sawv Cev ntawm Hybrid thiab Full-Ceramic Bearings
Qhov kev hloov pauv tseem ceeb tshaj plaws ntawm cov khoom siv yog kev siv cov khoom siv ua vaj tse engineering, feem ntau yog Silicon Nitride (Si3N4).
Cov Pob Bearings Sib Xyaws Sib Sib Zog: Cov no muaj cov nplhaib hlau ua ke nrog cov pob silicon nitride. Cov txiaj ntsig yog kev hloov pauv:
Qhov Ceev Tsawg Dua & Txo Lub Zog Centrifugal: Cov pob ceramic sib dua li hlau li 40%. Thaum muaj kev kub ceev (DN > 1 lab), qhov no txo qhov hnyav centrifugal ntawm lub nplhaib sab nraud, ua rau muaj kev kub ceev txog li 30%.
Kev Ruaj Khov & Kev Nyuaj Siab: Kev tiv taus kev hnav zoo ua rau lub neej qaug zog ntev dua nyob rau hauv cov xwm txheej zoo tagnrho.
Kev rwb thaiv hluav taws xob: Tiv thaiv kev puas tsuaj los ntawm kev hluav taws xob arcing (fluting) hauv cov cav hloov pauv zaus (VFD), ib hom kev ua tsis tiav.
Ua Haujlwm Thaum Kub Dua: Ua haujlwm tau nrog tsawg lubrication lossis nyob rau hauv qhov kub thiab txias dua li cov hlau bearings.
Cov Bearings Tag Nrho-Ceramic: Ua los ntawm silicon nitride lossis zirconia tag nrho. Siv rau hauv qhov chaw muaj kev kub ntxhov tshaj plaws: kev siv tshuaj lom neeg tag nrho, lub tshuab nqus tsev siab heev uas tsis tuaj yeem siv cov roj nplua nyeem, lossis hauv cov tshuab magnetic resonance imaging (MRI) uas xav tau tsis muaj hlau nplaum.
Kev Tsim Kho Qhov Chaw Siab Tshaj Plaws: Lub Hwj Chim ntawm Ob Peb Microns
Qee zaum, qhov kev txhim kho muaj zog tshaj plaws yog ib txheej me me ntawm qhov chaw ntawm cov hlau txheem.
Cov Txheej Txheem Carbon Zoo Li Pob Zeb Diamond (DLC): Ib txheej txheej uas tawv heev, du heev, thiab tsis sib txhuam ntau uas siv rau cov kab sib tw thiab cov pob. Nws txo qhov hnav ntawm cov nplaum thaum lub sijhawm pib (kev nplua nplua ciam teb) thiab muab ib qho kev thaiv tiv thaiv kev xeb, ua rau lub neej ua haujlwm ntev dua hauv cov xwm txheej tsis zoo.
Cov Txheej Txheem Physical Vapor Deposition (PVD): Cov txheej txheem Titanium Nitride (TiN) lossis Chromium Nitride (CrN) ua rau qhov chaw tawv dua thiab txo qhov sib txhuam, zoo tagnrho rau cov ntawv thov nrog kev nplua siab lossis kev nplua me ntsis.
Kev Siv Laser Texturing: Siv lasers los tsim cov qhov me me lossis cov channel ntawm qhov chaw sib tw. Cov no ua haujlwm ua cov chaw khaws roj nplua nyeem, ua kom ntseeg tau tias muaj zaj duab xis tas li, thiab tuaj yeem txo qhov sib txhuam thiab qhov kub ua haujlwm.
Kev Tsim Kho Tshiab hauv Polymer thiab Composite Technology
Cov Cages Polymer Tiam Tom Ntej: Tshaj li cov qauv polyamide, cov ntaub ntawv tshiab xws li Polyether Ether Ketone (PEEK) thiab Polyimide muab kev ruaj khov thermal zoo heev (kev ua haujlwm tas mus li > 250 ° C), kev tiv thaiv tshuaj lom neeg, thiab lub zog, ua rau cov tawb sib dua, ntsiag to dua rau cov ntawv thov ua haujlwm hnyav.
Cov Khoom Siv Fiber-Reinforced Composites: Kev tshawb fawb tseem tab tom ua rau cov nplhaib ua los ntawm cov polymers carbon-fiber reinforced (CFRP) rau kev siv ceev ceev, sib dua xws li aerospace spindles lossis miniature turbochargers, qhov twg txo qhov hnyav yog qhov tseem ceeb.
Kev Sib Koom Tes thiab Kev Xav Txog Yav Tom Ntej
Kev siv cov ntaub ntawv siab heev no yeej tsis yog yam tsis muaj teeb meem. Feem ntau lawv xav tau cov cai tsim tshiab (cov coefficients thermal expansion sib txawv, elastic moduli), cov txheej txheem machining tshwj xeeb, thiab muaj tus nqi pib siab dua. Txawm li cas los xij, lawv tus nqi Tag Nrho ntawm Kev Muaj Tswv (TCO) hauv kev siv raug yog qhov sib tw tsis muaj qhov sib tw.
Xaus Lus: Kev Tsim Kho Tus Ciam Teb ntawm Qhov Ua Tau
Yav tom ntej ntawm cov kabmob sib sib zog nqus tsis yog hais txog kev ua kom cov hlau zoo xwb. Nws yog hais txog kev sib xyaw cov khoom siv nrog kev tsim kho tshuab zoo nkauj. Los ntawm kev siv cov kabmob sib xyaw ua ke, cov khoom siv DLC-coated, lossis cov cages polymer siab heev, cov engineers tam sim no tuaj yeem teev cov kabmob sib sib zog nqus uas ua haujlwm sai dua, ntev dua, thiab nyob rau hauv ib puag ncig uas tau suav tias txwv tsis pub ua. Qhov kev hloov pauv no ua rau cov khoom siv ua kom ntseeg tau tias cov khoom siv tseem ceeb no yuav txuas ntxiv ua kom tau raws li qhov xav tau ntawm cov tshuab niaj hnub no, los ntawm cov dav hlau hluav taws xob mus rau cov cuab yeej khawb tob. Lub sijhawm ntawm cov kabmob "ntse khoom siv" tau los txog.
