Cov hauv qab no yuav tsum tau txiav txim siab thaum xaiv qhov kawg ntawm lub cev muaj zog txhawb nqa (xws li lub cev muaj zog qhov kawg): (1) kev tswj xyuas qhov tseeb ntawm cov khoom siv tsav; (2) qhov xwm txheej ntawm cov khoom uas tau tsav los ntawm lub cev muaj zog; (3) cov kabmob lossis cov kabmob sib xyaw ua ke yuav tsum muaj peev xwm tiv taus qee qhov axial quab yuam. Raws li cov qauv tsim los saum toj no, qhov sib sib zog nqus groove pob bearings feem ntau yog siv los ua thawj qhov kev xaiv rau lub cev muaj zog qhov kawg ntawm cov kabmob me me thiabnruab nrab motors.
Sib sib zog nqus groove pob bearings yog cov feem ntau siv dov bearings. Thaum sib sib zog nqus groove pob bearings yog siv, lub cev muaj zog bearing txhawb system qauv yog heev yooj yim thiab yooj yim los tswj. Sib sib zog nqus groove pob bearings feem ntau yog siv los dais radial loads, tab sis thaum lub radial clearance ntawm cov kabmob yog nce, lawv muaj cov yam ntxwv ntawm angular hu pob bearings thiab tuaj yeem dais ua ke radial thiab axial loads; Thaum qhov ceev yog siab thiab thrust pob bearings tsis haum, lawv tuaj yeem siv los dais cov axial ntshiab. Piv nrog rau lwm hom bearings nrog tib qhov tshwj xeeb thiab qhov ntev li qhov sib sib zog nqus groove pob bearings, hom kabmob no muaj qhov zoo ntawm kev sib txhuam coefficient qis thiab siab txwv ceev, tab sis qhov tsis zoo yog tias nws tsis cuam tshuam-resistant thiab tsis haum rau cov kabmob hnyav.
Tom qab qhov sib sib zog nqus groove pob bearing yog ntsia rau ntawm ncej, radial haum ntawm ncej los yog vaj tse nyob rau hauv ob qho tib si cov lus qhia yuav raug txwv nyob rau hauv lub axial clearance ntau yam ntawm cov kabmob. Nyob rau hauv cov kev taw qhia radial, cov kabmob thiab cov ncej tau txais kev cuam tshuam zoo, thiab cov kabmob thiab qhov kawg npog cov kabmob chamber lossis vaj tse txais kev cuam tshuam me me. Lub hom phiaj tseem ceeb ntawm kev xaiv qhov haum no yog los xyuas kom meej tias kev ua haujlwm tshem tawm ntawm cov kabmob yog xoom lossis tsis zoo me ntsis thaum lub sijhawm ua haujlwm ntawm lub cev muaj zog, kom kev ua haujlwm ntawm cov kabmob zoo dua. Nyob rau hauv cov kev taw qhia axial, axial haum ntawm qhov chaw ntawm cov kabmob thiab cov khoom muaj feem xyuam yuav tsum tau txiav txim siab ua ke nrog rau cov xwm txheej tshwj xeeb ntawm cov kabmob floating kawg. Lub nplhaib puab ntawm cov kabmob yog txwv los ntawm cov kabmob txoj haujlwm txwv cov kauj ruam (lub xub pwg nyom) ntawm tus ncej thiab cov kabmob tuav lub nplhaib, thiab lub nplhaib sab nraud ntawm cov kabmob yog tswj los ntawm qhov haum rau cov kabmob thiab cov kabmob chamber, qhov siab ntawm qhov nres ntawm sab hauv thiab sab nrauv ntawm cov kabmob, thiab qhov ntev ntawm cov kabmob chamber.
(1) Thaum lub ntab kawg xaiv cov kabmob sib cais nrog cov nplhaib sab hauv thiab sab nrauv, lub nplhaib sab nraud ntawm cov kabmob ntawm ob qhov kawg yog sib npaug nrog tsis muaj kev tshem tawm axial.
(2) Thaum lub ntab kawg xaiv cov kabmob uas tsis sib cais, qee qhov ntev ntawm axial clearance yog sab laug ntawm lub nplhaib sab nraud ntawm cov kabmob thiab nres ntawm cov kabmob npog, thiab qhov haum ntawm lub nplhaib sab nraud thiab cov kabmob chamber yuav tsum tsis txhob nruj heev.
(3) Thaum lub cev muaj zog tsis muaj qhov tseeb qhov kawg thiab ntab kawg, qhov sib sib zog nqus groove pob bearings feem ntau yog siv rau ntawm ob qho kawg, thiab kev sib raug zoo yog tias lub nplhaib sab nraud ntawm cov kabmob txwv tau kaw nrog lub hau sab hauv thiab muaj qhov sib txawv ntawm lub nplhaib sab nraud thiab lub hau npog sab hauv ntawm axial; los yog lub nplhaib sab nraud ntawm cov bearings ntawm ob qho kawg yog txuam nrog tsis muaj axial clearance nruab nrab ntawm lub nplhaib sab nrauv ntawm cov kabmob thiab cov kabmob npog, thiab muaj qhov sib txawv ntawm lub nplhaib sab nraud thiab lub hau npog sab hauv ntawm axial kev taw qhia.
Cov kev sib raug zoo saum toj no yog tag nrho cov kev sib raug zoo tsim nyog tau txheeb xyuas theoretically. Qhov tseeb bearing configuration yuav tsum phim cov kev khiav hauj lwm tej yam kev mob ntawm lub cev muaj zog, nrog rau tej yam tsis xws li clearance, tshav kub kuj, precision, thiab lwm yam.
Nws yuav tsum raug sau tseg tias qhov kev tshuaj ntsuam saum toj no tsuas yog rauhorizontally ntsia motors, thaum rau vertically ntsia lub cev muaj zog, ob qho tib si xaiv cov bearings thiab cov kev sib raug zoo sib xws yuav tsum muaj cov cai tshwj xeeb.
