Kev Kho Mob Kub Carburizing rau Cov Gears: Txhim Kho Lub Zog, Kev Ruaj Khoov & Kev Ua Tau Zoo

Hauv cov tshuab xa hluav taws xob niaj hnub no, cov iav yuav tsum ua haujlwm nyob rau hauv qhov xwm txheej hnyav heev, lub zog siab, kev sib hloov tas mus li, cov khoom hnyav, kev hloov pauv ceev, thiab kev ua haujlwm ntev. Cov hlau alloy ib txwm muaj, txawm tias muaj qhov tawv zoo, feem ntau tsis tuaj yeem tiv taus cov ntawv thov nyuaj xws li tsis muaj kev puas tsuaj ntawm qhov chaw, cov hniav pitting, scuffing, hnav, thiab qaug zog tawg. Txhawm rau kov yeej cov teeb meem no, kev kho cua sov ua ib kauj ruam tseem ceeb hauv kev tsim iav, thiab ntawm txhua txoj kev,carburizingsawv tawm ua ib qho ntawm cov txheej txheem ua kom tawv nqaij zoo tshaj plaws.

Carburizing (tseem hu ua case hardening) yog ib txoj kev siv hlau uas qhia cov pa roj carbon rau hauv txheej saum npoo ntawm cov iav hlau ntawm qhov kub siab. Tom qab quenching, qhov saum npoo hloov mus ua ib lub rooj plaub martensitic tawv thaum lub hauv paus tseem muaj zog thiab tiv taus kev poob siab. Qhov kev sib xyaw ua ke no tawv sab nraud, tawv sab hauv. yog vim li cas cov iav carburized siv dav hauv kev sib kis tsheb, cov iav kev lag luam, cov tshuab hnyav, cov khoom siv mining, cov tsav tsheb aerospace, thiab cov neeg hlau.

Carburizing yog dab tsi?

Carburizing yog kev kho cua sov raws li diffusion ua ntawm qhov kub feem ntau ntawm 880 ° C - 950 ° C. Thaum lub sijhawm ua haujlwm, cov iav raug cua sov hauv huab cua nplua nuj carbon. Cov pa roj carbon atoms diffuse rau hauv txheej txheej ntawm cov hlau, ua rau nws cov pa roj carbon ntau ntxiv. Tom qab soaking rau lub sijhawm xav tau, cov iav raug quenched sai sai los tsim ib lub rooj plaub martensitic hardened.

Qhov tob ntawm cov pa roj carbon nkag mus rau hauv lub thawv hu ua qhov tob ntawm lub thawv, thiab tuaj yeem tswj tau los ntawm kev hloov pauv qhov kub thiab txias, lub sijhawm tuav, thiab lub peev xwm ntawm cov pa roj carbon. Feem ntau, qhov tob ntawm lub thawv uas xav tau yog txij li 0.8 hli txog 2.5 hli, nyob ntawm seb daim ntawv thov, qhov loj ntawm lub iav, thiab lub peev xwm thauj khoom xav tau.

Vim li cas Gears thiaj xav tau Carburizing?

Kev siv carburizing tsis yog tsuas yog hais txog kev ua kom tawv xwb; nws tseem ua rau kev ua haujlwm zoo dua hauv kev ua haujlwm tiag tiag. Cov txiaj ntsig tseem ceeb suav nrog:

1. Kev Tiv Thaiv Kev Hnav Siab
   Qhov chaw tawv tawv tiv thaiv kev hnav abrasive, pitting, micro-spalling, thiab kev puas tsuaj ntawm qhov chaw.

2. Muaj Peev Xwm Nqa Tau Ntau Dua
   Cov iav carburized tuaj yeem nqa cov khoom hnyav dua thiab xa cov torque siab dua yam tsis muaj kev hloov pauv.

3. Txhim Kho Lub Zog Khoov Hniav
   Lub plawv mos mos thiab yoog tau nqus tau kev poob siab thiab kev cuam tshuam, txo qhov kev pheej hmoo ntawm kev tawg hniav.

4. Lub Neej Qaug Zog Zoo Tshaj Plaws
   Cov iav carburized tuaj yeem ua haujlwm rau kaum tawm txhiab teev hauv cov xwm txheej siab.

5. Txo Kev Sib Txhuam & Kev Tsim Kub
   Kev sib koom tes ntawm cov hniav du dua ua kom muaj kev sib kis ntsiag to thiab siv hluav taws xob ntau dua.

Vim yog cov txiaj ntsig no, carburizing tau dhau los ua kev kho cua sov txheem rautshebcov iav, tshwj xeeb tshaj yog raucov iav bevel, helical iav, nplhaib iav, sib txawv iav, thiab kis tau tus ncej.

Cov Txheej Txheem Carburizing Kauj Ruam Yog Kauj Ruam

Ib qho txheej txheem carburizing tag nrho suav nrog ntau theem, txhua qhov cuam tshuam rau kev ua tau zoo kawg:

1. Ua Ntej Kub thiab Austenitizing

Cov iav raug cua sov mus rau qhov kub carburizing qhov twg hlau hloov mus ua austenite. Cov qauv no tso cai rau carbon kom diffuse tau yooj yim.

2. Kev Sib Kis Cov Pa roj Carbon thiab Kev Tsim Cov Ntaub Ntawv

Cov iav tau tuav rau hauv ib puag ncig uas muaj cov pa roj carbon ntau (roj, lub tshuab nqus tsev, lossis cov khoom siv carburizing khov). Cov pa roj carbon atoms diffuse mus rau hauv, tsim ib lub thawv tawv tom qab quenching.

3. Kev tua hluav taws

Kev txias sai hloov cov txheej saum npoo uas muaj cov pa roj carbon ntau mus ua martensite—tawv heev thiab tiv taus kev hnav.

4. Kev kub ntxhov

Tom qab quenching, tempering yog qhov yuav tsum tau ua kom txo qhov brittleness, txhim kho toughness, thiab stabilize lub microstructure.

5. Kev Siv Tshuab Kawg / Kev Sib Tsoo

Cov iav kho cua sov feem ntau raug sib tsoo lossis lapping kom ua tiav cov qauv hniav raug, cov qauv sib cuag du, thiab kev tswj suab nrov zoo tshaj plaws.

Hom Carburizing rau Gears

Muaj ntau yam thev naus laus zis carburizing tau tsim tawm, txhua tus muaj cov txiaj ntsig tshwj xeeb.

Ntawm lawv,nqus tsev carburizingyog qhov nyiam dua rau cov iav precision vim nws cov ntaub ntawv faib tawm sib xws, kev phooj ywg ib puag ncig, thiab kev cuam tshuam tsawg.

Kev Xaiv Khoom Siv Rau Carburizing

Tsis yog txhua cov hlau yog cov uas siv tau rau carburizing. Cov ntaub ntawv zoo tshaj plaws yog cov hlau sib xyaw uas muaj cov pa roj carbon tsawg uas muaj zog thiab lub plawv tawv.

Cov hlau carburizing feem ntau:

• 16MnCr5

• 20CrMnTi

• 8620 / 4320 Hlau

• 18CrNiMo7-6

• SCM415 / SCM420

Cov hlau no tso cai rau lub thawv tawv tob thaum tseem tswj tau lub hauv paus ruaj khov, ductile - zoo meej rau cov iav hnyav.

Cov Yam Zoo Hauv Cov Gears Carburized

Yuav kom ua tiav kev ua tau zoo ruaj khov, yuav tsum tswj tau ntau yam tseem ceeb:

1. Kev sib sau ua ke ntawm cov pa roj carbon ntawm qhov chaw

2. Qhov tob ntawm cov ntaub ntawv siv tau (ECD)

3. Qib austenite khaws cia

4. Kev cuam tshuam thiab kev ruaj khov ntawm qhov ntev

5. Kev sib npaug ntawm qhov nyuaj (58–62 HRC ntawm qhov chaw)

Ib qho txheej txheem carburizing uas tswj tau zoo ua kom cov iav ua haujlwm tau zoo rau ntau xyoo nrog kev saib xyuas tsawg kawg nkaus.

Cov ntawv thov ntawm Carburized Gears

Carburizing yog siv dav hauv cov lag luam uas qhov kev ntseeg tau, kev ua kom raug, thiab kev ua haujlwm siab yog qhov tseem ceeb:

• Cov gearboxes thiab differential systems ntawm tsheb

• Tsheb laij teb, kev khawb av thiab cov khoom siv hnyav

• Cov khoom siv robotics thiab automation

• Cov iav kis ntawm cua turbine

• Cov tsav tsheb aerospace thiab turbine transmissions

• Cov txheej txheem tsav nkoj hauv dej hiav txwv

Txhua qhov chaw uas cov iav yuav tsum tiv taus kev poob siab, kev nyuaj siab thiab kev ntxhov siab ntev, kev siv carburizing yog qhov kev daws teeb meem ntseeg siab tshaj plaws.

Kev kho cua sov carburizing hloov cov iav hlau ib txwm mus rau hauv cov khoom ua tau zoo uas muaj peev xwm nyiaj dhau qhov chaw nyuaj. Cov txheej txheem no ua kom lub ntsej muag muaj zog tiv thaiv kev hnav thiab qaug zog thaum khaws cia lub hauv paus sab hauv kom tiv taus kev cuam tshuam. Thaum cov tshuab hloov zuj zus mus rau qhov muaj zog ntau dua thiab ua haujlwm tau zoo, cov iav carburized yuav tseem yog cov thev naus laus zis tseem ceeb hauv kev tsim kho niaj hnub thiab cov kab ke xa hluav taws xob.
