Lub xyoo dhau los, kev tshawb fawb hauv tsev thiab txawv teb chaws thiab kev txhim kho ntawm cov mos txwv tau ua tiav cov txiaj ntsig zoo thiab kev nce qib ntau.Hauv tshuab cov cuab yeej siv tshuaj, tshuaj lom neeg, aerospace thiab lwm cov teb tau thov siv thiab ua si tau cov txiaj ntsig.
Tej hub bearings muaj cov zoo li nram qab no zoo dua tag nrho cov hlau-bearings:
1. Kev sib hloov ceev thiab nrawm nrawm muaj peev xwm - nws tuaj yeem ua haujlwm hauv cov xwm txheej ntawm dn tus nqi ntau dua 3 lab, thiab tuaj yeem txo qhov kev sib tw, hnav thiab kub;
2. Kev pab lub neej ntev thiab hnav tsis kam - lub neej kev qaug zog ntawm txhua tus-tej hub bearings xav tias 10-50 lub sij hawm ntev dua li ntawm txhua-hlau steel, thiab lub neej kev pabcuam ntawm kev sib xyaw tej hub kuj yog li 3-5 zaug. ntev tshaj qhov uas ntawm txhua yam-steel bearings;
3, qhov kev xav tau rau lubrication yog tsawg heev - cov khoom siv ceramic txhuam kev sib txhuam coefficient yog tsawg, kev siv cov roj-lubricated ceramic bearings, nyob rau hauv cov ntaub ntawv ntawm lubricating roj thinning los yog roj tsis zoo, nws lub peev xwm lubrication tsis qis dua li cov roj sib tov uas feem ntau siv hauv cov kabmob hlau;
4. Abrasion tsis kam - vim hais tias cov khoom siv pob zeb (ceramic) yog qhov khoom siv tsis tau ntxiv, nws yuav tiv taus xeb thiab hnav;
5. High rigidity - vim yog lub siab elastic modulus ntawm cov ntaub ntawv ceramic, lawv cov rigidity yog 15-20% loj dua qhov ntawm cov hlau tsis zoo;
6. Qhov kub ua haujlwm siab - tag nrho cov kab nrig ceramic tuaj yeem ua haujlwm kub siab dua 500C;
7. Tsawg torque - raws li cov qauv, lub zog lub zog ntawm cov kabmob ceramic yog txo los ntawm 1/3;
8. Lub tshuab tsis muaj hlau nplaum thiab tsis muaj qhov ncaj ncees - cov nplaim hluav taws xob tsis muaj kev puas tsuaj los ntawm cov hlau nplaum lossis hluav taws xob.
Nrog rau kev txhim kho ntawm cov kev tshawb fawb thiab cov neeg coob ntawm cov kev sib tawg hauv kev tsim tshuab, cov roj hmab ceramic yuav muaj kev cia siab hauv cov liaj teb ntawm kev kub ceev, siab kub thiab tiv thaiv corrosion.
