Ha u khetha bearing, u lokela ho nahana ka lintlha tse 'maloa tsa bohlokoa.Ntlha ea pele eo ho lokelang ho nahanoa ka eona ke mojaro oo ho o jara.Ho na le mefuta e 'meli ea meroalo.
-Axial load : e tsamaellanang le axis ea ho potoloha
-Radial load: perpendicular to the axis of rotation
Mofuta o mong le o mong oa ho jara o etselitsoe ho ts'ehetsa meroalo ea axial kapa radial.Li-bearings tse ling li ka jara mefuta e 'meli ea meroalo: re li bitsa meroalo e kopaneng.Ka mohlala, haeba ho jara ha hao ho tlameha ho jara moroalo o kopantsoeng, re khothalletsa hore u khethe seqha sa tapered.Haeba o hloka bering e ka mamellang meroalo e phahameng ea radial, re khothaletsa hore ho be le cylindrical roller bear.Ka lehlakoreng le leng, haeba ho jara ha hao ho hloka ho tšehetsa meroalo e bobebe, ho tšeloa bolo ho ka lekana, kaha hangata li-bearings tsena li theko e tlaase.
Lebelo la ho potoloha ke ntlha e 'ngoe e lokelang ho nahanoa.Li-bearings tse ling li khona ho mamella lebelo le holimo.Kahoo, dibering rolara cylindrical le dibering nale rolara le koaletsoeng na le lebelo le phahameng rotational bapisoa le dibering ntle koaletsoeng.Leha ho le joalo, ka linako tse ling lebelo le phahameng le tla ka litšenyehelo tsa mojaro.
Hape u lokela ho nahana ka ho kheloha ho ka khonehang;li-bearings tse ling ha li tšoanelehe bakeng sa sena, mohlala li-bearings tsa bolo ea mela e 'meli.Ka hona, tlhokomelo e lokela ho lefshoa kahong ea li-bearings: li-bearings tse tsosolositsoeng le li-bearings tse chitja li na le tšekamelo ea ho se lumellane ho itseng.Re khothaletsa hore o sebelise li-bearings tse ikamahanyang le tsona ho itokisa, e le hore u lokise ka bohona liphoso tse bakoang ke ho kobeha ha shaft kapa liphoso tse ntseng li eketseha.
Hape, maemo a ts'ebetso a bohlokoa haholo ha u khetha sebaka se loketseng.Ka hona, hoa hlokahala ho sekaseka tikoloho ea ts'ebetso eo ho eona ho tla sebetsa.Li-bearings tsa hau li ka ba tlas'a mefuta e fapaneng ea litšila.Lisebelisoa tse ling li ka baka tšitiso ea lerata, litšisinyeho le/kapa ho thothomela.Ka hona, li-bearings tsa hau li tlameha ho khona ho mamella lits'oants'o tsena ka lehlakoreng le leng mme li se ke tsa baka tšitiso ka lehlakoreng le leng.
Ntlha e 'ngoe ea bohlokoa e lokelang ho nahanoa ke ho beha bophelo.Lintho tse sa tšoaneng, tse kang lebelo kapa ho sebelisoa khafetsa, li ka ama bophelo ba ho beleha.
Ho khetha mokhoa oa ho tiisa ke senotlolo sa ho netefatsa hore li-bearings tsa hau li sebetsa hantle le ka nako e telele;ka hona, ke habohlokoa ho etsa bonnete ba hore li-bearings li lula li sirelelitsoe hantle ho litšila leha e le life le lintho tse ka ntle tse kang lerōle, metsi, maro a senyang kapa esita le lisebelisoa tse sebelisoang.Khetho ena e itšetlehile ka mofuta oa lubricant, maemo a tikoloho (ka hona hape le mofuta oa tšilafalo), khatello ea mokelikeli le lebelo.
Ho u fa sebaka se setle sa ho qala, khatello ea mokelikeli ke eona ntho e ka sehloohong khethong ea mokhoa oa ho tiisa.Haeba khatello e phahame ka ho lekaneng (mohlala, sebakeng sa 2-3 bar), tiiso ea mochine e loketse.Ho seng joalo, khetho e tla amana ka ho toba le mofuta oa lubricant, grease kapa oli.Ka mohlala, bakeng sa lubrication ea mafura, tharollo e tloaelehileng ka ho fetisisa ke: li-deflectors kapa gaskets, mechine e entsoeng ka mochine kapa e moqotetsane e nang le li-grooves;tabeng ea ho tlotsa oli, mokhoa oa ho tiisa hangata o
