Ceramic bearings

Ceramic bearings, tseem hu ua hybrid bearings, yog tsim los ntawm cov khoom siv ceramic (Si3N4 lossis ZrO2) thiab cov nplhaib hlau lossis ceramic. Lawv tau siv dav hauv ntau daim ntawv thov kev lag luam vim lawv qhov kev ua tau zoo dua piv rau cov kabmob hlau tsoos.

Khoom siv:
Ceramic bearings feem ntau yog ua los ntawm silicon nitride (Si3N4) lossis zirconia (ZrO2) vim lawv cov khoom siv zoo heev. Lawv muaj lub zog siab, hardness, thiab nruj, nrog rau cov thermal conductivity tsawg, coefficient ntawm thermal expansion, thiab ntom piv rau cov tsoos hlau bearings.

Qhov ntau thiab tsawg:
Ceramic bearings tuaj nyob rau hauv ntau qhov ntau thiab tsawg, los ntawm me me (ob peb millimeters) mus rau loj heev (ob peb meters inch). Qhov loj tshaj plaws yog nyob rau hauv thaj tsam ntawm 5-50 millimeters inch.

Daim ntawv thov:
Ceramic bearings yog siv nyob rau hauv ntau hom kev lag luam, xws li:

- Cov ntawv thov kev kub ceev: Ceramic bearings tuaj yeem tiv taus qhov nrawm dua li cov kabmob hlau ib txwm muaj, ua rau lawv zoo tagnrho rau cov tshuab ua haujlwm siab xws li turbines, compressors, thiab motors.
- Kev siv kub heev: Ceramic bearings tuaj yeem ua haujlwm ntawm qhov kub siab dua li cov kabmob hlau, ua rau lawv tsim nyog siv rau hauv qhov chaw kub kub xws li cov chaw tsim khoom thiab cov nroj tsuag tshuaj.
- Corrosive ib puag ncig: Ceramic bearings yog resistant rau corrosion, ua rau lawv haum rau siv nyob rau hauv hnyav tshuaj ib puag ncig xws li nyob rau hauv cov roj thiab roj kev lag luam.
- Kev siv kho mob thiab kho hniav: Ceramic bearings yog biocompatible thiab tuaj yeem siv rau hauv cov khoom siv kho mob thiab kho hniav xws li cov pob qij txha thiab kev kho hniav.

Qhov zoo:
Qhov zoo ntawm ceramic bearings muaj xws li:

- Kev ua tau zoo dua: Ceramic bearings muaj kev sib txhuam qis dua, nruj dua thiab ua rau qaug zog ntxiv piv rau cov kabmob hlau, ua rau kev txhim kho kev ua haujlwm thiab lub neej ntev dua.
- Kev saib xyuas qis: Ceramic bearings xav tau kev saib xyuas tsawg dua li cov kabmob hlau, nrog rau kev pabcuam ntev dua thiab txo qis kev xav tau lubrication.
- Tsis kam hnav thiab corrosion: Ceramic bearings yog cov resistant rau hnav thiab corrosion, ua rau lawv haum rau hnyav ib puag ncig.
- Lub teeb yuag: Ceramic bearings yog qhov hnyav dua li cov kabmob hlau, ua rau txo qis kev siv zog thiab txhim kho kev ua haujlwm ntawm cov tshuab.

Qhov tsis zoo:
Qhov tsis zoo ntawm ceramic bearings muaj xws li:

- Tus nqi siab dua: Ceramic bearings yog kim dua rau kev tsim khoom dua li cov kabmob hlau tsoos, ua rau cov nqi siab dua rau cov neeg siv khoom kawg.
- Brittle: Cov ntaub ntawv ceramic yog nkig ntau dua li cov hlau, ua rau lawv yooj yim rau kev ua tsis tiav yog tias muaj kev ntxhov siab lossis poob siab.
- rhiab heev rau kev teeb tsa tsis raug: Ceramic bearings tuaj yeem nkag siab rau kev teeb tsa tsis raug tshaj li cov kabmob hlau, xav tau kev saib xyuas ntau dua thiab kev txawj ntse thaum lub sijhawm teeb tsa.
