Selelekela
Li-rolara tsa mela e mene li fumaneha ka meralo e mengata:
● e nang le cylindrical kapa tapered bore
● e butsoe kapa e tiisitsoe
Mela e mene ea li-cylindrical roller bearings li sebelisoa hoo e batlang e le feela bakeng sa melala ea mekotla ea litepisi tsa leloala, li-calender le li-roller.Hobane hangata li kenngoa ka mokhoa oa ho kena-kenana le tšitiso molaleng oa moqolo, li-bearings tsa li-cylindrical roller li loketse hantle bakeng sa lisebelisoa tsa leloala moo lebelo la ho bilika le leng holimo.
Hobane li-rolara tsa mela e mene li ka nka meroalo feela ea radial, li hokahantsoe hammoho le li-groove tse tebileng kapa li-angular ball bearings, kapa ka li-roller bearings (ebang ke radial kapa thrust design) tse amohelang meroalo ea axial.
Likarolo le Melemo
● Bokhoni bo ikhethang ba ho jara mojaro o phahameng
Ka lebaka la palo e phahameng ea li-roller, li-bearings tsa cylindrical roller tsa mela e mene li loketse meroalo e boima haholo ea radial.
● Khohlano e tlase (Roller end / flange contact area)
Moralo o bulehileng oa flange, mmoho le moralo oa lirolara le pheletso ea bokaholimo, li khothaletsa sebopeho sa filimi ea lubricant e bakang khohlano e tlase.
● Bophelo bo bolelele ba tšebeletso
Boemo ba "logarithmic roller" bo fokotsa khatello ea kelello ho motho ea kopanang le roller / peisong le kutloelo-bohloko le ho kheloha ha shaft.
● Botšepehi bo ntlafalitsoeng ba ts'ebetso
Qetello ea bokaholimo holim'a marang-rang a lirolara le litselana tsa lebelo e ts'ehetsa ho etsoa ha filimi ea lubricant ea hydrodynamic.
● E ka arohanngoa ebile e ka fapanyetsanoa
Likarolo tse arohaneng tsa li-bearings tsa XRL tsa mela e mene ea cylindrical li ka fetoha.Sena se thusa ho hlongoa le ho theoloa, hammoho le tlhahlobo ea tlhokomelo.
● Bokhoni ba lebelo le phahameng
Liqapi tsa cage li loketse lebelo le phahameng, ho potlakisa ka potlako le ho jara tlhōrō.
● Bophahamo bo tlase bo fapaneng
Bophahamo bo tlase ba li-rolara tse nang le mela e mene ea li-cylindrical roller bo lumella hore ho be le bophara bo boholo ba molala ha bo bapisoa le bophara ba moqolo.
Tšebeliso
Mefuta e mene ea li-cylindrical rolara hangata e arohanngoa, ke hore, lesale la ka hare la conical le nang le lesale la ka hare la rolara le kopano ea ho boloka li ka kenngoa ka thoko ho lesale la ka ntle la conical (lesale la ka ntle).
