Qhov ceev ntawm lub cev muaj zog bearing yog tsuas yog txwv los ntawm qhov kub thiab txias tshwm sim los ntawm kev sib txhuam thiab kub hauv cov qauv bearing.Thaum qhov ceev tshaj ib qho kev txwv, cov kabmob yuav tsis tuaj yeem tig mus txuas ntxiv vim qhov kub hnyiab, thiab lwm yam. Qhov kev txwv ceev ntawm cov kabmob yog hais txog qhov txwv tus nqi ntawm qhov ceev uas cov kabmob tuaj yeem tig tsis tu ncua yam tsis muaj kev sib txhuam ntawm cov cua sov uas yuav ua rau. kub hnyiab.Yog li ntawd, kev txwv ceev ntawm cov kabmob yog nyob ntawm ntau yam xws li hom, qhov loj thiab qhov tseeb ntawm cov kabmob, cov txheej txheem lubrication, qhov zoo thiab qhov ntau ntawm cov roj nplua nyeem, cov khoom siv thiab hom ntawm lub tawb, thiab cov khoom thauj.

Cov kev txwv ceev ntawm ntau yam bearings siv roj lubrication thiab roj lubrication (roj da dej lubrication) tau teev nyob rau hauv txhua lub rooj loj.Cov txiaj ntsig sawv cev rau tus qauv tsim cov kabmob raws li kev thauj khoom dav dav (C / P≥13, Fa/Fr≤0.25 los yog li ntawd ) yog tus nqi txwv ntawm qhov kev sib hloov ceev thaum tig ntawm qhov ceev.Kho qhov kev txwv ceev: load mob C / P <13 (uas yog, qhov sib npaug dynamic load P tshaj li ntawm 8% ntawm qhov yooj yim dynamic load ntsuas C), los yog thaum lub axial load nyob rau hauv lub load ua ke tshaj 25% ntawm radial load. , nws yuav tsum Siv kab zauv (1) los kho qhov txwv ceev.ua = f1·f2·n…………(1) Kho qhov txwv, rpm, kev kho coefficient ntsig txog kev thauj khoom (Daim duab 1), kev kho coefficient ntsig txog qhov tshwm sim (Fig. 2), qhov txwv ceev raws li kev thauj khoom dav dav, rpm (saib cov bearing size table) Basic dynamic load rating, N{kgf} equivalent dynamic load, N{kgf} radial load, N{kgf} axial load, N{kgf} ncej motor thiab high-speed rotation Kev ceev faj: Bearings thaum tig ntawm siab ceev, tshwj xeeb tshaj yog thaum qhov ceev nyob ze los yog tshaj 70% ntawm qhov txwv ceev sau tseg nyob rau hauv lub dimension, cov teeb meem hauv qab no yuav tsum tau them rau:

(1) Siv cov bearings siab

(2) Txheeb xyuas qhov kev tshem tawm sab hauv ntawm cov kabmob (xav txog qhov kub nce hauv cov kabmob) Kev txo qis)

(3) Tshawb xyuas cov khoom siv ntawm lub tawb (4) Txheeb xyuas cov txheej txheem lubrication.
