'Mele o sintered o entsoeng ka mokhoa oa metallurgy ea phofo o na le masoba 'me o na le melemo ea tekheniki ea ho fetola palo, boholo, sebopeho le kabo ea masoba ka bolokolohi haholoanyane ts'ebetsong ea tlhahiso. Ha o sebelisa masoba a 'mele o sintered, o koaheloa ka 10%-40% (karolo ea bophahamo) ea oli e tlotsang, 'me o sebelisoa boemong ba phepelo ea oli ea hau. Nakong ea ts'ebetso, mocheso oa bearing oa phahama, 'me kaha coefficient ea katoloso ea oli e kholo ho feta ea tšepe, e kena ka bohona holim'a metsi ho tlotsa bearing. Libearing tse kenngoeng ka oli li ka sebelisoa nako e telele ka oli e le 'ngoe, 'me hangata li sebelisoa maemong ao ho leng thata ho tlatsa mafura.

Li-bearing tse itlotsangLi arotsoe ka li-bearing tse itlotsang tse kopantsoeng, li-bearing shaft tse tiileng tse itlotsang tse kentsoeng ka hare, li-bearing tse itlotsang tse entsoeng ka thepa ea bimetallic, le li-bearing tse khethehileng tse itlotsang tse entsoeng ka thepa.

 

E 'ngoe ea mefuta e meholo ea li-bearing tse tiileng tse itlotsang tse koahetsoeng ka letsoho (tse bitsoang JDB) ke bearing e ncha e tlotsitsoeng e nang le litšobotsi tsa bearing ea tšepe le bearing ea setlolo e se nang oli, e tlatsitsoeng ke matrix ea tšepe 'me e tlotsitsoe ka thepa e entsoeng ka ho khetheha ea setlolo e tiileng.

 

E na le litšobotsi tsa bokhoni bo phahameng ba ho jara, ho hanyetsa tšusumetso, ho hanyetsa mocheso o phahameng, bokhoni bo matla ba ho itlotsa, jj., e loketse haholo bakeng sa mojaro o boima, lebelo le tlase, ho pheta-pheta kapa ho sotha le liketsahalo tse ling tse thata ho tlotsa le ho etsa filimi ea oli, 'me ha e tšabe khoholeho ea metsi le ho senyeha ha li-acid tse ling. Lihlahisoa li 'nile tsa sebelisoa haholo mechineng ea ho lahla e tsoelang pele ea tšepe, lisebelisoa tsa ho phutholla, mechini ea merafo, hlobo, mechini ea ho phahamisa, mechini ea masela, tlhahiso ea matla a moea, likepe, li-turbine tsa mouoane, li-turbine tsa metsi, mechini ea ho etsa ente le mela ea tlhahiso ea lisebelisoa.

Phapang pakeng tsali-bering tse kenngoeng ka oli le li-bering tse itlotsang

 

1. Bearing e kentsweng ka oli e entsoe ka phofo ea tšepe e kopantsoeng, ka sebaka sa sebopeho sa 10-40%; Matrix ea bearing e itlotsang e kentsoeng ka hare ke casting ea centrifugal; Botenya ba substrate bo phahame haholo, matla a ho kopanya a phahame ho feta a li-bearing tse kentsweng ka oli, 'me bophelo ba tšebeletso bo bolelele ho feta ba li-bearing tse kentsweng ka oli.

 

2. Thepa e tlotsang ea bearing e kenngoeng ka oli ke oli e tlotsang, 'me filimi ea oli e na le botenya bo lekaneng ho felisa ho kopana ka ho toba pakeng tsa libaka tse peli tsa khohlano. Nakong ena, ho na le khohlano feela pakeng tsa limolek'hule tse metsi, kahoo coefficient ea khohlano e nyane haholo (f = 0.001 ~ 0.008), e leng se fokotsang khohlano le ho tsofala haholo. Thepa e tlotsang e kenelletsoeng ka bearing e itlotsang ke thepa e tiileng e tlotsang, e ka ntseng e e-na le phello e ntle ea ho tlotsa esita le tlas'a maemo a se nang oli, e ka netefatsang ho tlotsa ho sa khaotseng le ho tšoarellang, 'me bophelo ba eona bo sebetsang ba ho tlotsa bo tsamaellana le bophelo ba matrix;

 

Oli e tlotsang e ka har'a bearing e kentsweng ka oli e fetoha habonolo ebile e bonolo ho e lahla, 'me tahlehelo ea filimi ea oli e tlotsang e potlakisoa tlas'a mocheso o phahameng le khatello e phahameng, 'me phello e loketseng ea ho tlotsa e ke ke ea fumanoa; Ka har'a graphite copper sleeve, setlolo se tiileng se fetisetsoa kapa se khutlisetsoa morao holim'a khohlano ka khohlano, 'me setlolo se tiileng se ka har'a lesoba kapa groove se fetisetsoa kapa se khutlisetsoa morao ho etsa filimi e tiileng ea phetisetso e nang le setlolo se setle, se khomaretsoeng ka tieo le sekoahelo se ts'oanang holim'a khohlano, e leng se fokotsang khohlano le ho tsofala haholo. Ha khohlano e ntse e tsoela pele, setlolo se tiileng se kentsweng se fanoa khafetsa holim'a khohlano, ho netefatsa ho tlotsa ho hotle ha para ea khohlano nakong ea ts'ebetso ea nako e telele.
