Kev xam thiab ntsuas lub peev xwm ntawm cov kabmob yog qhov tseem ceeb los xyuas kom meej tias nws tuaj yeem txhawb nqa cov khoom siv tau zoo yam tsis muaj kev ua haujlwm ntxov ntxov. Nov yog cov kauj ruam uas koom nrog hauv txoj haujlwm no:
1. Txiav txim siab hom kev thauj khoom: Qhia txog hom kev thauj khoom uas cov kabmob yuav raug. Qhov no tuaj yeem suav nrog radial loads, axial loads, lossis ob qho tib si ua ke.
2. Xam cov load sib npaug: Nyob rau hauv rooj plaub uas muaj ob qho tib si radial thiab axial loads, nws yog tsim nyog los xam qhov sib npaug load. Qhov no yog ua los ntawm kev hloov cov khoom sib txawv rau hauv ib qho kev thauj khoom ua haujlwm ntawm cov kabmob qhov chaw.
3. Txiav txim siab dynamic load ntsuam xyuas (C): dynamic load ntsuam xyuas yog ib tug siv tus nqi muab los ntawm cov bearing chaw tsim tshuaj paus thiab sawv cev rau lub load uas ib tug bearing yuav muaj ib tug xam 90 feem pua kev ntseeg ntawm kev ua tiav ib tug tsawg kawg nkaus ib lab revolutions. Nws yog feem ntau teev nyob rau hauv cov khw catalog rau txawv bearing hom thiab ntau thiab tsawg.
4. Txiav txim siab qhov kev nyab xeeb (SF): Qhov kev nyab xeeb yog siv rau qhov ntsuas qhov ntsuas qhov hnyav kom suav nrog kev hloov pauv hauv kev ua haujlwm, tsis paub tseeb hauv kev kwv yees, thiab lwm yam. Qhov tsim nyog kev nyab xeeb yog nyob ntawm daim ntawv thov thiab feem ntau yog muab los ntawm cov tuam txhab bearing lossis cov qauv kev lag luam.
5. Xam qhov yooj yim dynamic load ntsuam xyuas (C0): Muab cov dynamic load ntsuam xyuas (C) los ntawm qhov kev nyab xeeb yam (SF). Qhov no muab tus nqi hloov kho uas qhia txog lub peev xwm ntawm cov kabmob raws li cov ntawv thov tshwj xeeb.
6. Ntsuam xyuas cov xwm txheej thauj khoom: Sib piv cov kev ntsuas qhov nruab nrab dynamic load (C0) nrog rau qhov tseeb load. Yog hais tias qhov tseeb load tsawg tshaj li qhov xam load peev xwm, lub bearing yuav tsum tau tuav lub load txaus. Yog hais tias qhov tseeb load tshaj lub peev xwm load, nws yog tsim nyog los xaiv ib tug loj bearing los yog xav txog lwm txoj kev daws teeb meem.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev suav cov peev txheej yuav tsum tau ua raws li cov qauv kev lag luam tsim thiab cov txheej txheem tsim khoom lag luam. Tsis tas li ntawd, tej yam xws li ceev, kub, lubrication, thiab mounting tej yam kev mob yuav tsum tau txiav txim siab los xyuas kom meej lub load peev xwm ntsuas. Hauv cov ntawv thov nyuaj, nws raug nquahu kom sab laj nrog cov tuam txhab tsim khoom lossis cov kws tshaj lij kev lag luam rau kev pabcuam hauv kev suav cov peev txheej.
