Mekhoa ea Nts'etsopele ea Lisebelisoa tsa ho Roller Bearing

 

In ho bearing e bilikanangtlhahiso, thepa ea thepa e khetholla ka ho toba nako ea bophelo ba bearing, botšepehi le maemo a sebetsang a ts'ebetso. Hona joale, likarolo tsa bearing li ntse li entsoe haholo-holo ka tšepe e nang le chromium e nang le khabone e ngata, joalo ka GCr15 le GCr15SiMn e tloaelehileng. Lilemong tsa morao tjena, ka nts'etsopele ea lisebelisoa tse lebisang lebelong le phahameng, meroalo e boima, mocheso o phahameng le maemo a rarahaneng a ts'ebetso, thepa ea bearing le eona e ntse e ntlafatsoa khafetsa, haholo-holo e bonts'a litaelo tse latelang tsa nts'etsopele:

 

1. Tšepe e nang le ho tiea ho hoholo

 

Ho fihlela litlhoko tsa likarolo tse kholo tsa ho bea tse nang le mabota a teteaneng, indasteri e ntlafalitse butle-butle litšepe tse nang le ho tiea ha matla, tse kang GCr15SiMo le GCr18Mo. Lisebelisoa tsena li ka fumana sebopeho se tšoanang se thatafetseng ka litekanyo tse kholo tsa ho tšela, ho ntlafatsa matla le bophelo ba mokhathala ba likarolo, 'me li loketse li-bearing tse kholo le lisebelisoa tse boima.

 

2. Tšepe e Tiileng ea ho Beha ka Holimo

 

Tšepe e thatafalitsoeng holim'a GCr4 e atisa ho sebelisoa lisebelisoa tse boima tse kang likoloi tsa terene le li-roller mills. Ka ho sebelisa ho futhumatsa ha induction ea maqhubu a mahareng le ho pholisa ka potlako, lera le thatafalitsoeng la botebo bo itseng le ka thehoa holim'a likarolo, e leng se etsang hore bearing e be thata haholo holim'a bokaholimo le ho tiea ho hoholo ha mantlha, ka hona ho ntlafatsa ho hanyetsa mokhathala le ho hanyetsa tšusumetso.

 

3. Mefuta e Mecha ea Tšepe e sa Khaotseng e Behellang

Litšepe tse sa ruseng tsa setso tse kang 9Cr18 le 9Cr18Mo (440C) li na le khanyetso e ntle ea mafome, empa li na le tšekamelo ea ho etsa li-carbide tse mafome, tse amang bophelo ba mokhathala le boleng ba bokaholimo. Tšepe e sa ruseng ea martensitic ea 0.7C-13Cr e ntlafalitsoeng lilemong tsa morao tjena, ka ho fokotsa khabone le chromium le ho fokotsa li-carbide tsa eutectic, e ntlafatsa ts'ebetso ea mokhathala oa ho kopana, ho tiea, le khanyetso ea mafome ea li-bearings. E sebelisoa hangata ho li-bearings tse nepahetseng tse sa ruseng, joalo ka li-bearings tsa hard drive le li-bearings tsa lisebelisoa tsa bongaka.

 

4. Tšepe e nang le motsoako o matla haholo

 

Litšepe tse nang le li-bearing tsa letoto la GT, ka lebaka la sebopeho se ntlafalitsoeng sa alloy, li ntlafatsa matla a matrix le ho tiea le ho ntlafatsa botsitso ba ho tenyetseha. Li loketse meralo ea li-bearing tse boima kapa tse bobebe, li na le bophelo bo botle ba ts'ebeletso tlas'a maemo a hloekileng a ho tlotsa.

 

5. Tšepe e hanelang ho silafala

 

Litšebelisong tse sebetsang, lerōle kapa likaroloana tse tsofalang ka har'a oli e tlotsang li ka etsa masoba holim'a bokaholimo ba bearing, e leng se lebisang ho tsepamisoeng ha khatello ea maikutlo le ho khathala pele ho nako. Ho rarolla bothata bona, Japane e ntlafalitse letoto la TF la litšepe tse hanelang tšilafalo (tse kang TF, HTF, STF, NTF, jj.).

 

Ka ho ntlafatsa dikarolelano tsa dikahare tsa khabone le dielemente tsa alloy, thepa e bopa dikharbide tse ntle tse ngata mme e eketsa austenite e bolokilweng, ka hona e fokotsa kgatello ya maikutlo mathokong a ho kenella. Phihlelo e sebetsang e bontsha hore di-bearing tse entsweng ka di-steel tsa letoto la TF di ka ba le nako ya bophelo e telele ka makgetlo a 4-10 tlasa maemo a tshilafatso a silafetseng.

 

6. Tšepe e nang le mocheso o phahameng e nang le tšepe e nang le mocheso o phahameng

Ha dibering tse tlwaelehileng tsa GCr15 di sebediswa dibakeng tse pakeng tsa 100℃ le 200℃, "sebaka se sesweu se kganyang" se thatafalang hanyane se hlaha habonolo hodima lera le ka tlase ho thepa, ka hona se fokotsa bophelo ba ho bea. Ho rarolla bothata bona, ditshipi tse nang le mocheso o phahameng jwalo ka NTJ2 le KUJ7 di se di ntshetsitswe pele. Ka ho eketsa ka nepo dikahare tsa dielemente tse kang Cr, Si, le Mo, ho thehwa ha dibaka tse tshweu tse kganyang ho a hatelloa, ho dumella dibering ho boloka nako e ntle ya bophelo le botsitso ba tekanyo esita le ho 150℃.～180℃. Lisebelisoa tsena li sebelisoa haholo lienjeneng tsa likoloi, lijenereithara le lisebelisoa tse sebetsang ka mocheso.

 

7. Tšepe e nang le mocheso o phahameng

Maemong a tshebetso a mocheso o phahameng le lebelo le phahameng jwalo ka sefofane, thepa ya setso ha e a lekana. Ditshepe tsa pele tse nang le mocheso o phahameng jwalo ka T1, T2, T10, le M50, le hoja di na le boima bo phahameng ba mocheso o phahameng, di na le dikahare tse ngata tsa alloy le ditjeo tse phahameng.

 

Lilemong tsa morao tjena, Europe le United States li thehile moloko o mocha oa litšepe tsa carburizing tse nang le mocheso o phahameng, tse kang M50NiL, CBS1000, le RBD. Har'a tsona, M50NiL ke eona e sebelisoang haholo. Kamora carburizing, li-carbide tse tšesaane lia thehoa holim'a metsi, li hlahisa khatello e setseng ea khatello. Matla a eona a mantlha a ka fihla makhetlo a 2.5 ho feta a M50, e leng se fellang ka bophelo bo phahameng ba mokhathala. Hona joale, e sebelisoa haholo-holo masimong a lisebelisoa tsa maemo a holimo joalo ka li-bearing tsa shaft tsa aero-engine. Ka kakaretso, nts'etsopele ea thepa ea ho bea e bilikanang e ntse e tsoela pele ho ea matla a phahameng, ts'epo e phahameng, khanyetso ea tšilafalo, khanyetso ea mafome, le ts'ebetso ea mocheso o phahameng. Ka nts'etsopele ea lifofane, lisebelisoa tse ncha tsa matla, le tlhahiso ea maemo a holimo, lipatlisiso le ts'ebeliso ea thepa e ncha ea ho bea e tla tsoela pele ho teba, e fana ka tšehetso e matla ea tekheniki bakeng sa ho ntlafatsa ts'ebetso ea ho bea.
