Rau kev xaiv ntawm qhov kawg ntawm lub cev muaj zog bearing kev txhawb nqa (xa mus rau qhov ruaj), cov hauv qab no yuav tsum tau txiav txim siab: (1) Kev tswj xyuas qhov tseeb ntawm cov khoom siv tsav; (2) Qhov xwm txheej ntawm lub cev muaj zog tsav; (3) Bearing lossis bearing ua ke Yuav tsum muaj peev xwm tiv taus ib qho kev quab yuam axial. Kev sib xyaw cov qauv tsim ntawm peb yam saum toj no, hauv cov motors me me thiab nruab nrab, qhov sib sib zog nqus groove pob bearings feem ntau yog siv los ua thawj qhov kev xaiv rau lub cev muaj zog taag kawg bearings.
Sib sib zog nqus groove pob bearings yog cov feem ntau siv dov bearings. Thaum siv qhov sib sib zog nqus groove pob bearings, cov qauv ntawm lub cev muaj zog txhawb nqa qhov system yooj yim heev, thiab kev saib xyuas kuj yooj yim. Sib sib zog nqus groove pob bearings yog tsuas yog siv los dais radial loads, tab sis thaum lub radial clearance ntawm cov bearings yog nce, lawv muaj cov yam ntxwv ntawm angular hu pob bearings thiab muaj peev xwm dais ua ke radial thiab axial loads; thrust pob tsis haum rau kev kub ceev Thaum siv los ua cov kabmob, nws kuj tuaj yeem siv los dais axial load. Piv nrog rau lwm hom bearings nrog tib yam specifications thiab qhov ntev li qhov sib sib zog nqus groove pob bearings, hom bearings no muaj qhov zoo ntawm kev sib txhuam me me coefficient thiab siab txwv ceev, tab sis qhov tsis zoo yog tias nws tsis tiv taus qhov cuam tshuam thiab tsis haum rau hnyav hnyav.
Tom qab qhov sib sib zog nqus groove pob bearing yog ntsia rau ntawm ncej, nyob rau hauv qhov ntau ntawm axial clearance ntawm cov kabmob, radial haum ntawm ncej lossis lub tsev nyob rau hauv ob qho tib si cov lus qhia yuav raug txwv.Nyob rau hauv cov kev taw qhia radial, cov kabmob thiab cov ncej txais kev cuam tshuam haum, thiab cov kabmob thiab qhov kawg npog cov kabmob chamber lossis plhaub tau 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 me ntsis thaum lub sijhawm ua haujlwm ntawm lub cev muaj zog. Tsis zoo, yog li kev khiav haujlwm ntawm cov kabmob zoo dua.Nyob rau hauv cov kev taw qhia axial, axial kev koom tes ntawm qhov chaw cov kabmob thiab cov khoom sib txuas yuav tsum tau txiav txim siab ua ke nrog cov xwm txheej tshwj xeeb ntawm cov kabmob uas tsis yog qhov chaw.Lub nplhaib puab ntawm cov kabmob yog txwv los ntawm cov kabmob txoj haujlwm txwv cov kauj ruam (ncej xub pwg) ntawm tus ncej thiab cov kabmob tuav lub nplhaib, thiab lub nplhaib sab nraud ntawm cov kabmob yog tswj los ntawm kev ua siab ntev ntawm cov kabmob thiab cov kabmob chamber, qhov siab ntawm qhov kev txiav txim siab 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, cov nplhaib sab nraud ntawm cov kabmob ntawm ob qho kawg tau txais axial clearance-free haum.
(2) Thaum cov kabmob tsis sib cais raug xaiv rau qhov kawg ntab, qee qhov ntev ntawm axial clearance yog tshwj tseg ntawm lub nplhaib sab nraud ntawm cov kabmob thiab cov seam ntawm cov kabmob npog, thiab qhov haum ntawm lub nplhaib sab nraud thiab cov kabmob chamber. tsis yooj yim kom 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 ntawm lub nplhaib sab nraud ntawm cov kabmob txwv thiab lub hau sab hauv yog daig, thiab muaj axial. qhov sib txawv ntawm lub hau sab nrauv thiab lub hau sab nrauv; Los yog tsis muaj axial clearance nruab nrab ntawm lub nplhaib sab nraud ntawm cov kabmob ntawm ob qho kawg thiab sab nrauv ntawm cov kabmob, thiab muaj qhov axial clearance ntawm lub hau thiab sab hauv.
Cov kev sib raug zoo saum toj no yog kev sib raug zoo tsim nyog raws li kev txheeb xyuas theoretical. 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 tsis kam, thiab raug nyob rau hauv lub xaiv ntawm lub cev muaj zog bearings, raws li zoo raws li bearings. Lub radial haum kev sib raug zoo nrog cov kabmob chamber, thiab lwm yam.
Nws yuav tsum tau muab sau tseg tias cov saum toj no tsom xam tsuas yog rau kab rov tav ntsia motors, tab sis rau vertically ntsia motors, yuav tsum muaj tej yam kev cai nyob rau hauv cov nqe lus ntawm kev xaiv ntawm bearings thiab muaj feem xyuam rau kev sib raug zoo.
