Cov yam ntxwv, qhov sib txawv thiab kev siv ntawm kaum plaub hom bearings
Cov kabmob yog cov khoom tseem ceeb tshaj plaws hauv cov tshuab thiab khoom siv. Nws lub luag haujlwm tseem ceeb yog txhawb nqa lub cev tig kom txo qhov sib txhuam ntawm cov khoom siv thauj khoom thaum lub sijhawm kis.
Raws li qhov kev taw qhia ntawm tus kabmob lossis lub kaum sab xis ntawm tus kabmob, cov kabmob no muab faib ua: radial bearing, thrust bearing.
Raws li hom dov khoom, nws muab faib ua: pob bearing, roller bearing.
Raws li seb nws puas tuaj yeem sib dhos, nws muab faib ua: tus kheej-aligning bearing, tsis-tus kheej-aligning bearing (rigid bearing).
Raws li tus naj npawb ntawm cov kem ntawm cov khoom dov, nws muab faib ua: ib kab bearing, ob kab bearing, thiab ntau kab bearing.
Raws li seb cov khoom puas tuaj yeem sib cais, nws muab faib ua: cov kabmob sib cais tau, cov kabmob tsis sib cais.
Tsis tas li ntawd xwb, muaj kev faib tawm los ntawm cov qauv thiab qhov loj.
Tsab xov xwm no feem ntau qhia txog cov yam ntxwv, qhov sib txawv thiab kev siv sib xws ntawm 13 tus kabmob sib xws.
