Cov yam ntxwv, qhov sib txawv thiab kev siv ntawm kaum plaub hom bearings
Cov kabmob yog cov khoom tseem ceeb hauv cov khoom siv kho tshuab. Nws lub luag haujlwm tseem ceeb yog txhawb nqa lub cev tig kom txo qhov kev sib txhuam ntawm cov khoom siv thaum lub sijhawm kis. Cov kabmob raug muab faib ua cov kabmob centripetal thiab cov kabmob thrust raws li cov lus qhia sib txawv lossis lub kaum sab xis. Raws li hom khoom dov, nws raug muab faib ua: pob kabmob, cov kabmob menyuam. Raws li seb nws puas tuaj yeem sib dhos, nws raug muab faib ua: cov kabmob sib dhos, cov kabmob tsis sib dhos (cov kabmob tawv). Raws li tus lej ntawm cov kem ntawm cov khoom dov, nws raug muab faib ua: ib kab kabmob, ob kab kabmob, thiab ntau kab kabmob. Raws li seb cov khoom puas tuaj yeem sib cais, nws raug muab faib ua: cov kabmob sib cais thiab cov kabmob tsis sib cais. Tsis tas li ntawd, muaj kev faib tawm los ntawm cov qauv duab thiab qhov loj me. Tsab xov xwm no feem ntau qhia txog cov yam ntxwv, qhov sib txawv thiab kev siv sib xws ntawm 14 cov kabmob sib xws.
