Dab tsi yog cov hom sib txawv ntawm cov bearings ceramic?

 

Cov kabmob ua los ntawm cov khoom siv ceramicsuav nrog zirconia ceramic bearings, silicon nitride ceramic bearings, thiab silicon carbide ceramic bearings. Cov ntaub ntawv tseem ceeb siv rau hauv cov bearings no yog zirconia (ZrO2), silicon nitride (Si3N4), thiab silicon carbide (SiC), uas muaj qhov nyuaj siab, tiv taus kev hnav siab, tiv taus kub siab, cov khoom siv kho tshuab zoo heev, thiab tiv taus oxidation.

 

Tshwj xeeb, cov bearings ceramic tuaj yeem faib ua pawg los ntawm cov khoom siv raws li hauv qab no:

 

Zirconium OxideCov kabmob ua los ntawm cov khoom siv ceramicCov nplhaib bearing thiab cov khoom dov yog ua los ntawm zirconia (ZrO2) cov khoom siv ceramic. Lub tawb feem ntau yog ua los ntawm polytetrafluoroethylene (PTFE), tab sis cov khoom siv tshwj xeeb xws li iav fiber reinforced nylon 66 (RPA66-25), cov yas engineering tshwj xeeb (PEEK, PI), stainless hlau (AISI SUS316), thiab tooj dag (Cu) kuj siv tau.

 

Silicon NitrideCov kabmob ua los ntawm cov khoom siv ceramicCov nplhaib bearing thiab cov khoom dov yog ua los ntawm silicon nitride (Si3N4). Piv rau ZrO2 bearings, lawv muaj kev ceev thiab lub peev xwm thauj khoom siab dua thiab tuaj yeem tiv taus qhov kub siab dua.

 

Silicon carbide ceramic bearings: Cov nplhaib bearing thiab cov khoom dov yog ua los ntawm silicon carbide (SiC), muaj cov khoom zoo heev xws li kev nyuaj siab, kev hnav tsis kam, kev nruj, thiab kev sib txhuam tsawg.

 

Tsis tas li ntawd xwb, cov bearings ceramic tuaj yeem raug cais los ntawm cov qauv raws li hauv qab no:

 

Cov kabmob ceramic tag nrhoOb lub nplhaib thiab cov khoom dov yog ua los ntawm cov khoom siv ceramic. Lub tawb muaj ntau yam kev xaiv, xws li polytetrafluoroethylene (PTFE), nylon 66, polyetherimide (PEEK), polyimide (PI), stainless hlau, lossis tshwj xeeb aerospace txhuas.

 

Cov kabmob ceramic sib xyaw: Cov nplhaib yog ua los ntawm cov hlau bearing lossis stainless hlau, thaum cov khoom dov yog cov pob ceramic. Lawv muaj cov yam ntxwv zoo heev xws li qhov ceev qis, qhov nyuaj siab, kev tiv thaiv kev hnav, kev ruaj khov, thiab kev sib txhuam tsawg, thiab lawv lub neej kev pabcuam ntev dua.

 

Cov kabmob ua los ntawm cov khoom siv ceramictuaj yeem faib ua pawg los ntawm daim ntawv thov raws li nram no:

 

Cov kabmob ceev ceev: Feem ntau siv rau hauv cov khoom siv ceev ceev, siab raug. Lawv muaj qhov elasticity qis thaum muaj kev ntxhov siab, lub zog compressive siab, lub teeb yuag, thiab qhov kub thiab txias ntau yam.

 

Cov kabmob kub siab: Siv rau hauv cov khoom siv kub siab, muaj peev xwm tiv taus qhov kub txog li 1200 ℃, thiab muaj cov khoom siv zoo rau tus kheej.

 

Cov kabmob uas tiv taus xeb: Siv rau hauv qhov chaw ib puag ncig hnyav uas xav tau kev tiv taus cov kua qaub muaj zog, alkalis, cov khoom sib xyaw organic, lossis dej hiav txwv.

 

Cov kabmob tiv thaiv hlau nplaum: Tsis yog hlau nplaum, siv rau hauv cov khoom siv demagnetizing, cov cuab yeej precision, thiab lwm yam, zoo tiv thaiv arcing thiab tawg ntawm cov khoom.

 

Cov kabmob rwb thaiv hluav taws xob: Muaj kev tiv taus siab, tiv thaiv kev arcing thiab kev tawg ntawm cov khoom, feem ntau siv rau hauv cov khoom siv hluav taws xob.

 

Cov kabmob nqus tsev: Cov khoom siv zoo rau tus kheej, siv rau hauv qhov chaw nqus tsev siab heev.
