Txhawm rau ua kom yooj yim rau kev sib piv nrog zawv zawg kabmob, txhuam kev sib txhuam ntawm dov bearings tuaj yeem xam raws cov kabmob sab hauv txoj kab los ntawm cov qauv hauv qab no:
* * * * * * * * * * * * * * * *
M=uPd / 2
* * * * * * * * * * * * * * * *
Ntawm no,
M: txhuam sij hawm, mn.m {kgf.mm}
U: txhuam coefficient, kev sib txhuam 1
P: cov kabmob load, N {KGF}
D: nominal ris ntawm cov kabmob, hli
Kev sib txhuam coefficient u zoo heev cuam tshuam los ntawm kev coj tus kheej, cov kabmob kis, kev nrawm nrawm, nrawm nrawm hom, thiab lwm yam. Cov nqi siv ntawm kev sib txhuam coefficient thaum kev sib hloov ruaj khov nyob rau hauv cov xwm txheej dav dav yog qhia hauv cov lus 1.
Rau cov kabmob ncaj qha, u=0.01-0. {{2}},, qee zaus txog 0.1-0. 2.
