Lisebelisoa tsa ho jara tse sebelisoang lipompong tsa centrifugal li arotsoe haholo ka mekhahlelo e 'meli: lisebelisoa tsa tšepe le lisebelisoa tse seng tsa tšepe.

Metallic Material

Lisebelisoa tsa tšepe tse sebelisoang hangata bakeng sa li-bearings tse thellang li kenyelletsa li-alloys tse nang le li-alloys (tse tsejoang hape e le li-alloys tsa Babbitt kapa li-alloys tse tšoeu), tšepe e sa sebetseng ho apara, li-alloys tsa koporo le aluminium.

1. Bearing Alloy

Likarolo tse ka sehloohong tsa motsoako oa li-alloys (tse tsejoang hape e le li-alloys tsa Babbitt kapa li-alloys tse tšoeu) ke thini, loto, antimony, koporo, antimoni le koporo, tse sebelisetsoang ho ntlafatsa matla le ho thatafala ha motsoako. Boholo ba likarolo tsa alloy tse nang le li-alloy li na le lintlha tse tlase tsa ho qhibiliha, kahoo li loketse maemo a ho sebetsa ka tlase ho 150 ° C.

2. Alloy e entsoeng ka koporo

Li-alloys tse entsoeng ka koporo li na le conductivity e phahameng ea mocheso le ho hanyetsa ho apara hantle ho feta tšepe. 'Me motsoako o entsoeng ka koporo o na le machinability e ntle le lubricity,' me lerako la eona le ka hare le ka phethoa, 'me le kopana le bokaholimo bo boreleli ba shaft. 

Lintho tse se nang tšepe

1. PTFE

E na le thepa e ntle ea ho itlotsa le botsitso bo phahameng ba mocheso. Coefficient ea eona ea likhohlano e nyane, ha e monye metsi, ha e khomarele, ha e chese, 'me e ka sebelisoa tlas'a boemo ba -180 ~ 250 ° C. Empa ho boetse ho na le mefokolo joalo ka katoloso e kholo ea mela, botsitso bo fokolang ba sebopeho, le ho se sebetse hantle ha mocheso. E le ho ntlafatsa ts'ebetso ea eona, e ka tlatsoa le ho matlafatsoa ka likaroloana tsa tšepe, likhoele, graphite le lintho tse sa tloaelehang.

2. Graphite

Ke thepa e ntle ea ho itlotsa, 'me hobane e bonolo ho e sebetsa,' me ha e ntse e le fatše, e boreleli, kahoo ke thepa ea khetho bakeng sa libere. Leha ho le joalo, thepa ea eona ea mechine e fokola, 'me e hanyetsa matla le matla a ho jara mojaro a fokola, kahoo e loketse feela liketsahalo tsa mojaro o bobebe. E le ho ntlafatsa thepa ea eona ea mochine, litšepe tse ling tse nang le fusible tse nang le khanyetso e ntle ea ho apara hangata li kenngoa. Lisebelisoa tse sebelisoang hangata ke Babbitt alloy, koporo alloy le antimony alloy. 

3. Rabara

Ke polymer e entsoeng ka elastomer, e nang le elasticity e ntle le ho monyeha ha letsoalo. Leha ho le joalo, conductivity ea eona ea mocheso e futsanehile, ho sebetsa ho thata, mocheso o amohelehang oa ho sebetsa o ka tlase ho 65 ° C, 'me o hloka metsi a potolohang ho tlotsa le ho pholile ho sa khaotse, kahoo ha a sebelisoe ka seoelo.

4. Carbide

E na le letoto la lintho tse ntle tse kang boima bo phahameng, ho hanyetsa ho roala, matla a matle le ho tiea, ho hanyetsa mocheso, le ho hanyetsa kutu. Ka hona, li-bearings tse thellang tse sebetsoang ka eona li na le ts'ebetso e nepahetseng e phahameng, ts'ebetso e tsitsitseng, boima bo phahameng, matla a matle, le ho tšoarella, empa li theko e boima.

5. SiC

Ke mofuta o mocha oa lintho tse entsoeng ka maiketsetso tse se nang tšepe. Ho thatafala ha ka tlase ho ba daemane. E na le khanyetso e ntle ea corrosion ea lik'hemik'hale, khanyetso ea ho roala, ho hanyetsa mocheso o phahameng, matla a phahameng a mochine, ts'ebetso e ntle ea ho itlotsa, ho hanyetsa mocheso o phahameng oa mocheso, ntho e nyenyane ea likhohlano, mocheso o phahameng oa mocheso, le coefficient e tlaase ea mocheso. E ka sebelisoa haholo E sebelisoa ho petroleum, metallurgy, indasteri ea lik'hemik'hale, mechine, sefofane le matla a nyutlelie le likarolo tse ling, hangata e sebelisoa e le lisebelisoa tse ferekaneng tsa libere tse thellang le litiiso tsa mechine.
