Cov kabmob yog cov khoom tseem ceeb hauv kev tsim khoom siv hauv kev lag luam. Qhov nyuaj ntawm cov kabmob yog qhov nyuaj dua, qhov hnav tsis kam ntawm cov kabmob yog qhov nyuaj dua, thiab qhov muaj zog ntawm cov khoom yog qhov nyuaj dua, yog li ntawd, kom ntseeg tau tias cov kabmob tuaj yeem tiv taus cov khoom hnyav dua thiab ua haujlwm tau ntev dua. Yog li ntawd, nws qhov nyuaj sab hauv yog qhov tseem ceeb heev rau nws lub neej kev pabcuam thiab qhov zoo.
Rau qhov kev sim qhov nyuaj ntawm cov hlau thiab cov hlau uas tsis yog ferrous bearing qhov chaw tom qab quenching thiab tempering thiab tiav cov bearing qhov chaw thiab cov hlau uas tsis yog ferrous bearing qhov chaw, cov txheej txheem sim tseem ceeb suav nrog Rockwell hardness test method, Vickers hardness test method, tensile strength test method thiab Leeb hardness test method, thiab lwm yam. Ntawm lawv, thawj ob txoj kev yog ntau dua thiab feem ntau siv hauv kev sim, thiab Brinell method kuj yog ib txoj kev yooj yim thiab feem ntau siv, vim nws qhov kev sim indentation loj thiab siv tsawg dua.
Txoj kev kuaj mob Rockwell hardness yog siv dav hauv kev lag luam bearing, thiab nws cov yam ntxwv tseem ceeb yog yooj yim thiab ceev.
Lub vijtsam kov digital zaub Rockwell hardness tester yooj yim rau kev siv. Nws tsuas yog yuav tsum tau thauj lub zog kuaj thawj zaug thiab lub tshuab ntsuas hardness yuav tau txais tus nqi hardness.
Txoj kev ntsuas qhov nyuaj ntawm Vickers yog tsom rau kev ntsuas qhov nyuaj ntawm tus ncej thiab lub tog raj kheej ntawm tus kabmob. Nws yuav tsum txiav thiab ua qhov kev sim qauv kom tau txais tus nqi nyuaj ntawm Vickers.
