Li-Roller Bearings tse chitja
Li-bearing tse chitja tsa li-roller ke karolo ea bohlokoa mechineng e boima ea indasteri, e nang le moralo o rarahaneng oa li-roller tse mela e 'meli tse li khethollang ho litharollo tse tloaelehileng tsa li-bearing. Lesale le ka ntle le entsoe ka tsela e le 'ngoe ea mabelo e chitja e arolelanoang, ha lesale le ka hare le ithorisa ka litsela tse peli tsa mabelo tse entsoeng ka nepo tse sekametseng ka lehlakoreng le itseng mabapi le axis e bohareng ea bearing. Sebopeho sena se bohlale sa sebopeho ke lejoe la motheo la ts'ebetso ea tsona e ikhethang, e li fa bokhoni ba tlhaho ba ho ikamahanya bo etsang hore li hanele haholo ho se lumellane hantle ha axial, ho kheloha ha likhutlo tsa matlo a bearing, le ho kobeha ha shaft.
Ho fapana le dibering tse tlwaelehileng tse thatafallwang ke ho se nepahale ha ho kenngwa, dibering tse chitja tse chitja di ipabola dibakeng tseo diphoso tsa angular di ke keng tsa qojwa ka lebaka la ho kgeloha ha shaft kapa ho se lokise hantle ha ntlo, e leng se netefatsang tshebetso e tsitsitseng esita le maemong a thata a kopano.
E 'ngoe ea litšobotsi tsa bohlokoa tse hlahelletseng tsa li-roller bearings tse chitja ke ts'ebetso ea tsona e phahameng ea ho ikamahanya. Tsela ea ho matha e chitja lesale le ka ntle e nolofalletsa lesale le ka hare le li-roller tse bōpehileng joaloka moqomo ho potoloha hantle, e leng se etsang hore shaft e se ke ea tsamaea hantle ho fihlela sebakeng se itseng - e leng tšobotsi ea bohlokoa haholo mechineng e boima moo ho leng thata ho boloka ho tsamaea hantle.
Ho tlatsetsang sena ke bokgoni ba tsona bo ikhethang ba ho jara boima bo phahameng: mola o habeli wa dirolara tse bōpehileng joaloka moqomo o aba boima ka ho lekana sebakeng se seholo sa ho kopana, o di dumella ho sebetsana ka katleho le meroalo e feteletseng ya radial, matla a maholo a ho tshoha, esita le meroalo e kopaneng ya radial le axial. Moralo ona o tiileng o netefatsa hore di ka mamella ditlhoko tse thata tsa tshebetso ya indasteri ntle le ho beha tshebetso kotsing kapa ho tshwarella.
Melemo ea li-roller bearings tse chitja e etsa hore e be khetho e ratoang bakeng sa lits'ebetso tsa indasteri lefatšeng ka bophara. Bophelo ba tsona bo bolelele ba ts'ebeletso ke molemo o ikhethang, haholo-holo bakeng sa mefuta e koetsoeng e etselitsoeng ho thibela tšilafalo e bakoang ke lerōle, litšila le mongobo - tšobotsi ea bohlokoa libakeng tse thata tsa indasteri moo lithōle li ka khutsufatsang bophelo ba li-bearings haholo.
Li-bearing tse chitja tse koetsoeng le tsona li hloka tlhokomelo e fokolang, kaha li tla li tlotsitsoe esale pele 'me li felisa tlhoko ea ho tlotsoa khafetsa, ho fokotsa nako ea ho sebetsa le litšenyehelo tsa ts'ebetso.
Ho tenyetseha ha tsona ke molemo o mong oa bohlokoa: li khona ho sebetsana ka mokhoa o se nang mathata le meroalo e kopaneng ea mahlaseli a maholo le a axial, e leng se etsang hore li lokele mefuta e fapaneng ea lits'ebetso ntle le tlhoko ea li-bearing tse khethehileng. Ho feta moo, kaho ea tsona e matla e netefatsa ho hanyetsa ho tsofala, esita le tlas'a ts'ebetso e tsoelang pele ea mojaro o boima, e fa likhoebo litharollo tse tšepahalang le tse theko e tlaase tsa ho bea tse ntlafatsang ts'ebetso ea mechini ka kakaretso.
