Mokhoa oa ho khetha sebaka se nepahetseng?

Ha u khetha sebaka se nepahetseng sa koloi, lintlha tse 'maloa li hloka ho nahanoa, 'me boima ba koloi ke bona bo bohlokoa ka ho fetisisa. Sena se ama ka kotloloho ts'ebetso ea koloi, bophelo ba ts'ebeletso le polokeho. Mona ke lintlha tsa bohlokoa tse lokelang ho nahanoa ha u khetha sebaka se nepahetseng:

1. Fumana Mefuta ea Moroalo eo ho Hlokahalang ho Jara
Ho latela ts'ebeliso, li-bearings li tla ba le mefuta e fapaneng ea meroalo. Sena se etsa qeto ea mofuta le moralo oa bere e hlokahalang. Mefuta e tloaelehileng ea meroalo e kenyelletsa:
• Radial Load: Mofuta ona oa mojaro o na le perpendicular ho axis e potolohang. Meroalo ea mahlaseli e atisa ho ba teng ha meroalo e sebelisoa ka thōko ho shaft e potolohang. Ka mohlala, ka li-motor, boima ba rotor le matla leha e le afe a eketsehileng a radial a tsoang lebanta kapa tsamaiso ea pulley e tla fana ka mojaro oa mahlaseli holim'a li-motor bearings.
• Moroalo oa Axial: Meroalo ea Axial e sebelisoa ka mokhoa o ts'oanang le motsoako o potolohang 'me o tloaelehile lits'ebetsong moo matla a sebelisoang ho latela tataiso ea axis. Mohlala o tloaelehileng ke oa li-hubs tsa mabili a makoloi, moo motsu o hlahisoang nakong ea ho potlakisa, ho braking, kapa ho reteleha, ho theha boima ba axial holim'a libering tsa mabili.
• Mojaro o Kopantsoeng: Lits'ebetsong tse ngata, li-bearings li tlas'a motsoako oa meroalo ea radial le axial. Meroalo ena e kopantsoeng e hloka li-bearings tse khonang ho sebetsana le mefuta e 'meli ea mojaro. Mohlala o sebetsang ke oa litsamaiso tsa ho fanyeha ha likoloi, moo li-bearings tsa mabili li mamellang meroalo e mebe ka bobeli ho tloha boima ba koloi le meroalo ea axial ho tloha ho reteleha le ho braking.
• Moroalo oa Motsotsoana: Ha matla a sebelisoa perpendicular ho axis ea bearing ka sebaka se itseng ho tloha bohareng ba setsi, moroalo oa motsotsoana o thehoa, o fellang ka nako ea ho khumama le khatello e eketsehileng holim'a ho beleha. Meroalo e joalo e atisa ho bonoa tsamaisong ea tsamaiso.

2. Khetha Right Bearing Type
Ho itšetlehile ka mefuta ea mojaro, maemo a ts'ebetso, le litlhoko tsa kopo, mefuta e fapaneng ea li-bearings e khethoa. Mefuta e tloaelehileng ea likoloi bakeng sa lisebelisoa tsa likoloi e kenyelletsa:
• Deep Groove Ball Bearings: E loketse ho sebetsana le meroalo e le 'ngoe ea radial kapa axial, kapa meroalo e kopantsoeng. Li-bearings tsena li sebelisoa haholo libakeng tsa mabili a likoloi le li-shafts tsa koloi.
• Cylindrical Roller Bearings: E etselitsoe ho sebetsana le meroalo e meholo ea radial ha e ntse e amohela meroalo e meng ea axial. Tsena li sebelisoa hangata lits'ebetsong tse jereng meroalo e boima.
• Angular Contact Ball Bearings: E loketse ho sebetsana le meroalo ea radial le axial ka nako e le 'ngoe. Tsena li sebelisoa hangata lits'ebetsong tsa ho emisoa ha likoloi le li-hubs tsa mabili.
• Nale Bearings: Haholo-holo e sebelisoa bakeng sa lisebelisoa tse phahameng tsa mahlaseli a mahlaseli libakeng tse thibetsoeng.

3. Ho Jara Mojaro Bokhoni
Bere e 'ngoe le e' ngoe e na le boima bo lekantsoeng ba mojaro, e bolelang boima bo boholo boo e ka bo khonang ka nako e itseng ha e ntse e boloka ts'ebetso e tsitsitseng. Bophahamo ba moroalo oa ho jara bo itšetlehile ka thepa ea eona, moralo le boholo ba eona. Mojaro o feteletseng o ka baka ho roala pele ho nako, ho hloleha, le ho ama hampe botsitso le polokeho ea sistimi.

4. Nahana ka Maemo a Ts'ebetso le Tikoloho
Ntle le matla a mojaro, tikoloho ea ts'ebetso ea bering e bapala karolo ea bohlokoa ts'ebetsong ea khetho. Ka mohlala:
• Mocheso: Haeba bethe ea koloi e sebetsa maemong a mocheso o phahameng kapa o tlase, lisebelisoa le mekhoa ea ho tlotsa e khonang ho mamella mocheso o feteletseng li hloka ho khethoa.
• Mongobo le Khoho: Libakeng tse mongobo kapa tse senyang, li-bearings tse nang le liphahlo tse sireletsang kapa litiiso li lokela ho khethoa ho lelefatsa bophelo ba tsona ba ts'ebeletso.
• Lebelo: Li-bearings tse sebetsang ka lebelo le phahameng li hloka ho ba le khohlano e tlase le boima bo phahameng ba mojaro, ho bolelang hore li-bearings tse nepahetseng li ka hlokahala.

5. Ho Bearing Size Selection
Ho jara boholo bo lokela ho khethoa ho latela litlhoko tse khethehileng tsa moralo oa koloi. Saese e tlameha ho netefatsa boima bo lekaneng ba mojaro ha ho nahanoa ka mathata a sebaka. Bearing e kholo haholo e ka 'na ea se ke ea kena mohahong o kopanetsoeng oa likoloi, athe bering e nyenyane haholo e ka' na ea se ke ea tšehetsa mojaro o hlokahalang.

6. Ho Bearing Lubrication le Tlhokomelo
Lubrication e nepahetseng ke ea bohlokoa bakeng sa ho jara ts'ebetso. Lubrication e sebetsang hantle e ka lelefatsa bophelo ba tšebeletso ea bere haholo. Ha u khetha li-bearings, ho bohlokoa ho nahana ka mokhoa oa ho tlotsa (oli kapa grease) le makhetlo a mangata a ho tlotsa, haholo-holo libakeng tse lebelo le phahameng kapa mocheso o phahameng.

7. Bokhoni ba Mojaro le Ntlha ea Tšireletso
Ha u khetha li-bearings, ntho ea polokeho e atisa ho nkoa e le ho etsa bonnete ba hore ho beleha ho ka sebetsana le meroalo e ka khonehang kapa li-spikes tsa tšohanyetso. Sebaka se khethiloeng se lokela ho ba le matla a lekaneng a mojaro ho thibela ho hlōleha ha maemo a thata.
