Litsamaisong tsa phetiso ea motlakase tsa sejoale-joale, li-gear li lebelletsoe ho sebetsa tlas'a maemo a feteletseng torque e phahameng, ho potoloha ho tsoelang pele, meroalo e boima, lebelo le feto-fetohang, le lipotoloho tse telele tsa mosebetsi. Litšepe tsa motsoako oa setso, leha li na le bothata bo botle ba tlhaho, hangata li ke ke tsa mamella lits'ebetso tse joalo tse boima ntle le ho hloleha ha bokaholimo, ho taboha ha meno, ho thibana, ho tsofala le ho petsoha ha mokhathala. Ho hlola liphephetso tsena, kalafo ea mocheso e ba mohato oa bohlokoa tlhahisong ea li-gear, 'me har'a mekhoa eohle,ho kenya ka har'a carburizinge hlahella e le e 'ngoe ea mekhoa e sebetsang ka ho fetisisa ea ho thatafatsa bokaholimo.

Carburizing (e boetse e bitsoa ho tiisa likhechana) ke mokhoa oa metallurgical o kenyang khabone ka holim'a lera la likere tsa tšepe mochesong o phahameng. Kamora ho tima, bokaholimo bo fetoha khechana e thata ea martensitic ha karolo ea mantlha e ntse e boloka ho tiea le ho hanyetsa ho tšoha. Motsoako ona o thata kantle, o thata kahare Ke ka lebaka leo li-gear tse nang le carburised li sebelisoang haholo ho li-transmission tsa likoloi, li-gearbox tsa indasteri, mechini e boima, lisebelisoa tsa merafo, li-drive tsa lifofane le liroboto.

Carburizing ke eng?

Carburizing ke kalafo ea mocheso e thehiloeng ho hasana e etsoang mochesong o tloaelehileng o pakeng tsa 880°C - 950°C. Nakong ea ts'ebetso, li-gear li futhumatsoa sepakapakeng se nang le khabone e ngata. Liathomo tsa khabone li kenella ka holim'a lera la tšepe, li eketsa khabone ea eona. Kamora ho inela ka nako e hlokahalang, li-gear li tima ka potlako ho etsa lebokose le thata la martensitic.

Botebo ba ho kenella ha khabone bo bitsoa botebo ba khetla, 'me bo ka laoloa ka mocheso o fapaneng, nako ea ho tšoara, le bokhoni ba khabone. Ka kakaretso, botebo ba khetla e reriloeng bo tloha ho 0.8 mm ho isa ho 2.5 mm, ho latela ts'ebeliso, boholo ba gear, le bokhoni ba mojaro bo hlokahalang.

Ke Hobane'ng ha Li-Gear li Hloka Carburizing?

Ho kenya carburizing ha se feela taba ea ho eketsa thatafalo; ho ntlafatsa ts'ebetso haholo maemong a sebele a mosebetsi. Melemo ea bohlokoa e kenyelletsa:

1. Khanyetso e Phahameng ea ho Aparela
   Bokaholimo bo thatafetseng bo thibela ho tsofala ha mapetso, ho taboha ha mapetso, ho qhalana ha mapetso le tshenyo ya mokhathala wa bokaholimo.

2. Bokgoni bo Phahameng ba ho Jara Mejaro
   Li-gear tse nang le carburised li ka jara meroalo e boima 'me tsa fetisa torque e phahameng ntle le ho fetoha.

3. Matla a Ntlafetseng a ho Koba Meno
   Karolo e bonolo ea ductile e monya ho thothomela le ho otla ha leino, e fokotsa kotsi ea ho robeha ha leino.

4. Bophelo bo Phahameng ba Mokhathala
   Li-gear tse nang le khabone li ka sebetsa lihora tse mashome a likete maemong a phahameng.

5. Ho Fokotsa Khohlano le Tlhahiso ea Mocheso
   Ho kenya meno hantle ho netefatsa phetiso e khutsitseng le e bolokang matla haholoanyane.

Ka lebaka la melemo ena, ho sebelisa carburizing e se e le mokhoa o tloaelehileng oa ho phekola mocheso bakeng salikoloili-gear, haholo-holo bakeng sali-bevel gear, li-gear tse helical, li-gear tse llang, li-gear tse fapaneng, le li-shaft tsa phetisetso.

Mokhoa oa ho Khaola Carburing Mohato ka Mohato

Ts'ebetso e felletseng ea ho kenya carburing e kenyelletsa mekhahlelo e 'maloa, e' ngoe le e 'ngoe e ama ts'ebetso ea ho qetela:

1. Ho Futhumatsa Pele le ho Koahela

Likere li futhumatsoa ho fihlela mochesong oa carburizing moo tšepe e fetohang austenite. Sebopeho sena se lumella khabone ho hasana habonolo.

2. Ho Hasana ha Khabone le ho Thehoa ha Nyeoe

Likere li tšoaroa tikolohong e nang le khabone e ngata (khase, vacuum, kapa sesebelisoa se tiileng sa khabone). Liathomo tsa khabone lia ata ka hare, li etsa lebokose le thatafetseng ka mor'a ho tima.

3. Ho tima

Ho phodisa ka potlako ho fetola lera la bokaholimo ba khabone e ngata hore e be martensite—e thata haholo ebile e hanela ho tsofala.

4. Ho leka-lekanya

Kamora ho tima, ho nolofatsa hoa hlokahala ho fokotsa ho robeha ha bonolo, ho ntlafatsa ho tiea le ho tsitsisa sebopeho sa microstructure.

5. Ho Qetela ho Sila/Ho Sila

Li-gear tse phekotsoeng ka mocheso hangata lia siloa kapa lia qaptjoa ho fihlela sebopeho se nepahetseng sa meno, mokhoa o boreleli oa ho ama le ho laola lerata hantle.

Mefuta ea Carburizing bakeng sa Likere

Ho se ho ntshetswe pele mahlale a mmalwa a ho kenya di-carburizing, e nngwe le e nngwe e na le melemo e ikgethang.

Har'a bona,ho belisa ka vacuume ntse e ratoa haholo bakeng sa li-gear tse nepahetseng ka lebaka la kabo ea eona ea mabokose a tšoanang, botsoalle tikolohong, le ho sotha ho fokolang.

Khetho ea Thepa bakeng sa Carburizing

Hase litšepe tsohle tse amohelang khabone. Thepa e ntle ke litšepe tse nang le khabone e tlase tse thatafatsang hantle le ho tiea ha karolo e ka hare.

Litšepe tse tloaelehileng tsa carburizing:

• 16MnCr5

• 20CrMnTi

• Tšepe ea 8620/4320

• 18CrNiMo7-6

• SCM415 / SCM420

Litšepe tsena li lumella ho thatafala ha khetla e tebileng ha ka nako e ts'oanang li boloka karolo ea mantlha e tiileng, e ductile—e loketse likere tse boima.

Lintlha tsa Boleng ho Li-Gear tse nang le Carburised

Ho fihlella tshebetso e tsitsitseng, lintlha tse 'maloa tsa bohlokoa li tlameha ho laoloa:

1. Ho hlaka ha khabone holim'a metsi

2. Botebo bo sebetsang ba nyeoe (ECD)

3. Boemo ba austenite bo bolokiloeng

4. Ho sotha le botsitso ba litekanyo

5. Ho tšoana ha thatafalo (58–62 HRC holim'a metsi)

Ts'ebetso e laoloang hantle ea ho kenya li-carburing e netefatsa hore li-gear li sebetsa ka mokhoa o tšepahalang ka lilemo tse ngata ntle le tlhokomelo e ngata.

Litšebeliso tsa Li-Gear tse nang le Carburised

Carburizing e sebelisoa haholo liindastering moo ho tšepahala, ho nepahala le mamello e phahameng ea mojaro li hlokahalang:

• Li-gearbox tsa likoloi le litsamaiso tsa phapang

• Terekere, merafo le lisebelisoa tse boima

• Liroboto le li-gear tsa othomathiki

• Li-gearbox tsa turbine ea moea

• Li-drive tsa lifofane le li-transmission tsa turbine

• Mekhoa ea ho tsamaisa likepe

Hohle moo li-gear li lokelang ho mamella ho thothomela, khatello le khatello ea nako e telele ea ho potoloha, ho kenya carburizing ke tharollo e tšepahalang ka ho fetisisa.

Kalafo ea mocheso ea carburing e fetola li-gear tse tloaelehileng tsa tšepe hore e be likarolo tse sebetsang hantle tse khonang ho mamella tikoloho e thata. Ts'ebetso ena e matlafatsa bokaholimo khahlanong le ho tsofala le mokhathala ha ka nako e ts'oanang e boloka karolo e thata ea kahare bakeng sa ho hanyetsa tšusumetso. Ha mechini e ntse e fetoha ho ea ho matla a mangata le bokhoni bo phahameng, li-gear tse carburing li tla lula e le theknoloji ea bohlokoa boenjiniere ba sejoale-joale le litsamaiso tsa phetisetso ea motlakase.
