Li-bulldozer bearings ke likarolo tse sebetsang hantle tse etselitsoeng-mosebetsi o boima oa kaho joalo ka libulldozer, tse nang le mesebetsi ea mantlha. Ke karolo ea bohlokoa e ts'ehetsang likarolo tse potolohang kapa tse thellang, ho fokotsa sekhahla sa khohlano ea ho sisinyeha, 'me e jara mojaro o moholo o hlahisoang nakong ea ts'ebetso ea lisebelisoa, ho netefatsa ts'ebetso e nepahetseng le e tsitsitseng ea li-bulldozer. Moralo oa eona le ts'ebetso ea eona li hloka ho ikamahanya le maemo a khethehileng a ts'ebetso ea libulldozer - mojaro o phahameng, ho thothomela ho matla, lerole le phahameng, phapang e kholo ea mocheso le maemo a mang a thata.
Joalo ka likarolo tsa mantlha tsa phetisetso le ts'ehetso, li-bulldozer bearings li ajoa haholo lits'ebetsong tse ngata tsa bohlokoa tsa lisebelisoa. Tšebeliso ea bona e hloka ho bapisa ka nepo litšobotsi tsa mojaro, mekhoa ea ho sisinyeha, le maemo a tikoloho likarolong tse fapaneng. Tse latelang ke libaka tsa eona tsa mantlha tsa ts'ebeliso le litšobotsi:
Seseteme ea phetisetso ke "borokho" lipakeng tsa matla a bulldozer ho tloha enjineng ho ea mochining oa ho tsamaea, 'me li-bearings li hloka ho mamella litlamorao tse kopaneng tsa torque e phahameng, matla, le ho potoloha{0}}ka lebelo le phahameng:
Phetiso: Tšehetso ea "gear shaft" e ka hare e itšetlehile ka li-roller bearings (tse khonang ho mamella meroalo ea radial le axial) le li-cylindrical roller bearings (tse ikamahanyang le matla a radial ka lebelo le phahameng) ho netefatsa phetisetso e tsitsitseng ea matla nakong ea ho fetoha ha gear le ho fokotsa liphoso tsa meshing.
Drive shaft: Drive shaft e kopanyang gearbox le axle ea ho khanna, 'me li-bearings tsa eona hangata li ikamahanya le-li-roller bearings, tse ka ikamahanyang le ho kheloha hanyenyane ha shaft ea drive e bakoang ke liphoso tsa ho instola kapa likotola, ho qoba ho jamming.
Drive axle: Li-bearings tse sehlohlolong se seholo le phapang li hloka ho mamella torque e kholo ea phetisetso ea ho qetela, 'me lirolara tse nang le mela e habeli li sebelisoa hangata ho hasanya meroalo ka ho matlafatsa matla a ho ikopanya. Tsamaiso ea ho tsamaea e amana ka ho toba le fatše, 'me li-bearings li hloka ho mamella boima ba bulldozer ka boeona (lithane tse mashome) le matla a ho arabela fatše nakong ea ho khanna le ho sebetsa:
Drive wheel: Karolo ea mantlha e tsamaisang tšebetso ea pina, 'me li-bearings hangata li kholo-lirolara tse nang le mela e habeli. Reng e ka ntle ke ho kena-kenana le tšitiso e lumellanang le hub ea lebili, 'me selikalikoe se ka hare se tsitsitse ho halofo ea shaft, e ka mamellang meroalo e boima ea radial le axial thrust, ho etsa bonnete ba hore pina ha e thelle kapa ho kheloha.
Mabili a tšehetsang le a tšehetsang: Ho thetheha haufi le pina ho ts'ehetsa 'mele, li-bearings li hloka ho ba le khanyetso e matla le ho tiisoa. Li-roller bearings tse tiisitsoeng (tse kang li-cylindrical roller bearings tse nang le mehele ea ho tiisa rabara) hangata li sebelisoa ho thibela mobu le lehlabathe ho kena - haholo-holo libakeng tse seretse, merafong le libakeng tse ling, ho hlōleha ha tiiso ho ka baka ho apara ka potlako.
Lebili la tataiso: le tataisa tsela ea pina, 'me li-bearings tsa lona hangata li ikamahanya le li-roller bearings, tse ka ikamahanyang le ho kheloha ha li-angles tse bakoang ke ho fetoha ha pina le ho fokotsa "gnawing" ea pina.
Li-bulldozers, lisebelisoa tse theolelang, le lisebelisoa tse ling tse sebetsang li tla hlahisa litlamorao tse matla le matla a morao nakong ea ts'ebetso, 'me li-bearings li hloka ho feto-fetoha le maemo le ho hanyetsa tšusumetso:
Bulldozer blade hinge shaft: Ho hinge shaft e kopanyang lehare la bulldozer le moqomo oa oli o phahamisang, li-bearings tse kopaneng (li-radial joint bearings kapa li-angular joint joint bearings) li sebelisoa ho lumella lehare hore le sothe ka lehlakoreng le itseng nakong ea ho phahamisa le ho thekesela, ho qoba khatello ea maikutlo e bakoang ke likhokahano tse thata. Maemo a mang a sebelisa-li-bearings tse kopantsoeng tsa ho itlotsa (ho kenyeletsoa le mafura a tiileng) ho fokotsa litšenyehelo tse bakoang ke ho tlotsa oli khafetsa.
Sesebelisoa sa ho hlephisa: Moqomo o kopanyang pakeng tsa meno a hlephisang le foreimi e hloka ho mamella tšusumetso ha e kenngoa mobung o thata kapa lejoeng. Hangata ke bethe e kholo ea sliding kapa rolara e tiisitsoeng, e lekanyang matla a ho hanyetsa le bokhoni ba ho buffer.
Tšebeliso ea libering tsa bulldozer e hloka ho fihlela litlhoko tse tharo tsa mantlha:
Ho jara meroalo e boima: E entsoe ka sebopeho (rolara e tsamaisang mohala) le thepa (tšepe e phahameng-ea matla a ho jara) ho ikamahanya le boima ba lithane tse mashome;
Mamello ea tikoloho: Sebopeho se tiisitsoeng (labyrinth, double lip seal) le tse senyehileng-lisebelisoa tse manganga li hanela khoholeho ea lerōle, seretse, metsi le mocheso o phahameng;
Ho ikamahanya le maemo a matla: Li-bearings tse khethehileng tse kang centering le manonyeletso li lumella ho kheloha hanyenyane kapa ho senyeha ha likaroloana, ho qoba ho hlōleha ha pele ho bakoang ke khatello ea kelello e thata.
