Raws li ib qho tseem ceeb ntawm niaj hnub tshuab, kev ua tau zoo thiab kev ua haujlwm nruj ntawm cov khoom siv sib luag, cov ntaub ntawv ntawm cov khoom siv sib luag, pom cov ntsiab lus kev kawm tom qab nws los ntawm tus kws tshaj lij tom qab nws los ntawm kev tshaj lij Qhov Kev Xav .
Ua ntej, cov txheej txheem ntsuas pib nrog cov tsos tshuaj xyuas {{}} Cov kauj ruam ntawm cov kabmob me me yuav cuam tshuam cov kabmob ntawm cov kabmob ntawm cov kabmob.
Tom ntej no yog qhov tseeb qhov tseeb kev sim . qhov ntsuas tuab ntawm cov kabmob {{2} Txoj kev sib tw ntawm kev sib hloov kev sib hloov thiab sib txuam ntawm cov kabmob {}}
Kev sim tawv yog tom qab ntawd, thiab lub hardness ntawm cov kabmob tau sim siv cov khoom lag luam uas muaj peev xwm ua tau zoo thiab kev hloov chaw ua haujlwm ruaj khov thiab hloov chaw ua haujlwm hauv ib puag ncig thiab hloov chaw ua haujlwm ua haujlwm {2}
Ib qho ntxiv, metallographic tsom xam kuj tseem yog qhov tseem ceeb ntawm cov txheej txheem kev sim siab, yog qhov cuam tshuam nrog cov qauv kev sib tw, Cov kabmob .
Tom qab ua tiav cov kev ntsuam xyuas saum toj no, kev ntsuas kev ua haujlwm tsis sib xws
Cov txheej txheem ntsuas ntawm nyias-walled babbitt alloy bearings cov txheej txheem zoo thiab kev ua tau zoo ntawm cov khoom lag luam nruj thiab ruaj khov rau hauv {}}
