Letoto la ho Beha Roller

Li-roller bearing ke likarolo tsa bohlokoa tsa ho nepahala tse sebelisoang haholo mechineng ea masela, likopanong tsa likoloi, li-gearbox tsa indasteri le mechini e boima, li bapala karolo ea bohlokoa ho fokotseng khohlano le ho netefatsa motsamao o boreleli oa ho potoloha. Ka sebopeho, li-roller bearing tse tloaelehileng li na le mandrel 1 le li-bearing tse nepahetseng tse kentsoeng lipheletsong ka bobeli, tse entsoeng ka boqapi ho mamella maemo a thata a ts'ebetso libakeng tse fapaneng tsa indasteri. Jwalo ka likarolo tsa mantlha lits'ebetsong tsa phetisetso ea mechini, ts'epo ea tsona e ama ka kotloloho katleho, bophelo ba nako le polokeho ea ts'ebetso ea lisebelisoa tsohle.

Letoto la di-roller bearing le arotswe ka mokgwa o hlophisehileng ho latela maemo a mabedi a bohlokwa: sebopeho le moralo. Dikarohano tsa sebopeho di kenyeletsa di-roller bearing tsa cylindrical, di-roller bearing tse tapered, di-roller bearing tse chitja, le di-roller bearing tsa nale, e nngwe le e nngwe e etseditswe ho latela ditlhoko tse ikgethang tsa mojaro le sebaka. Diphetoho tsa moralo di akaretsa ditlhophiso tsa mola o le mong kapa mela e mmedi, meralo e flanged kapa e seng flanged, meaho e kwetsweng kapa e bulehileng, eo kaofela e ntlafaditsweng ho sebetsana le metswako e fapaneng ya meroalo e boima ya radial, meroalo ya axial, lebelo le phahameng la ho potoloha, le ho se dumellane ha shaft.

Ho utloisisa mefuta e meholo ea li-roller bearings ke habohlokoa bakeng sa ho etsa liqeto tse nang le tsebo mabapi le khetho:

Li-roller bearings tsa cylindrical li ipabola ho sebetsana le meroalo e boima ea radial le lebelo le phahameng la ho potoloha, 'me li ka amohela ho falla hanyane ha axial ntle le haeba masale ka bobeli a flanged - e leng se etsang hore e be a loketseng li-roller tsa mochini oa masela le li-shaft tsa motlakase. Li-roller bearings tse tapered li etselitsoe ho tšehetsa meroalo e kopaneng ea axial e phahameng ea radial le ea tataiso e le 'ngoe, 'me hangata li sebelisoa ka bobeli li-hub tsa mabili a likoloi le li-gearbox tsa indasteri ho leka-lekanya matla a mahlakoreng a mabeli.

Li-bearing tse chitja li hlahella ka bokhoni ba tsona ba ho sebetsana le meroalo e boima ea radial, meroalo ea axial e habeli, le ho lokisa ho se lumellane ha shaft ka bohona ho bakoang ke liphoso tsa ho kenya kapa ho kheloha ha ts'ebetso, e leng se etsang hore li lokele lisebelisoa tse boima joalo ka litsamaiso tsa conveyor le mechini ea merafo. Li-bearing tse nang le nale, tse nang le sebopeho se senyenyane le boima bo phahameng ba mojaro ha li bapisoa le boholo ba tsona, ke khetho e holimo bakeng sa lits'ebetso tse nang le sebaka se fokolang sa ho kenya, joalo ka lipompo tsa hydraulic le li-transmission tsa likoloi.

Li-bearing tsa roller tsa Thrust, ho kenyeletsoa le li-bearing tsa nale tse tšusumetsang, li entsoe ka ho khetheha ho mamella meroalo e phahameng ea axial, e sebelisoang hangata ho li-spindle tsa lisebelisoa tsa mochini le mekhoa ea lifti.

Ts'ebetso ea ho khetha roller bearing e nepahetseng e kenyelletsa tlhahlobo e felletseng ea liparamente tsa bohlokoa tsa ts'ebetso:
pele, hlwaya mofuta le boholo ba meroalo (radial, axial, kapa e kopaneng);
sa bobedi, fumana lebelo le hlokahalang la ho potoloha le boemo ba ho nepahala (bohlokwa bakeng sa ditshebediso tse nepahetseng haholo jwalo ka mechini ya CNC);
ea boraro, nahana ka mefuta ea mocheso o sebetsang (ho khetha li-bearings tse nang le thepa e loketseng e hanelang mocheso);
'me qetellong, hlahloba lithibelo tsa sebaka ho netefatsa hore bearing e lekana ka har'a enfelopo ea moralo oa lisebelisoa.
