Hnub Tim: Plaub Hlis 3, 2026

1. Kev Txheeb Xyuas Txog Kev Siv Tshuab: Lub Luag Haujlwm Tseem Ceeb ntawm Cov Khoom Siv Thauj Khoom Hauv Cov Tsheb Thauj Khoom Loj Doosan

Lub log tsheb thauj khoom—tseem hu ua lub log tsheb thauj khoom sab saud lossis lub log tsheb thauj khoom sab saud—yog ib qho tseem ceeb tab sis feem ntau tsis quav ntsej hauv lub kaw lus hauv qab ntawm cov tshuab khawb av loj. Thaum cov log tsheb thauj khoom hauv qab dais lub tshuab qhov hnyav tag nrho rau hauv av, cov log tsheb thauj khoom ua lub luag haujlwm sib txawv tab sis tseem ceeb ib yam: lawv coj thiab txhawb nqa qhov seem sab saud (rov qab) ntawm txoj saw hlau thaum nws mus ncig los ntawm lub sprocket tsav rov qab mus rau lub idler pem hauv ntej. Yog tsis muaj cov log tsheb thauj khoom ua haujlwm zoo, txoj saw hlau yuav sag ntau dhau, nplawm hnyav thaum mus ncig ceev ceev, thiab muaj kev pheej hmoo loj heev—tshwj xeeb tshaj yog thaum tig ntse lossis thaum hla thaj chaw tsis sib xws ntawm cov chaw khawb av.

Rau cov neeg ua haujlwm ntawm Doosan DX480, DX500, thiab DX520 excavators—49–52 tuj chav kawm tshuab hnyav uas tau siv dav hauv kev khawb av loj, kev khawb pob zeb, kev tsim kho hnyav, kev tsim kho vaj tse, thiab kev khawb av loj—qhov kev ntseeg tau ntawm lub rooj sib dhos ntawm cov menyuam nqa khoom cuam tshuam ncaj qha rau kev sib dhos ntawm txoj kev, lub neej ntawm cov khoom hauv qab, thiab tag nrho lub sijhawm ua haujlwm ntawm lub tshuab. Cov ntaub ntawv kev lag luam qhia tias cov khoom hauv qab tuaj yeem sawv cev rau ntau dua 30% ntawm tag nrho cov nqi kho khoom siv, ua rau kev txiav txim siab yuav khoom paub zoo tseem ceeb rau kev ua kom zoo tshaj plaws tag nrho cov nqi ntawm kev muaj.

Tsab ntawv tshaj tawm no muab kev tshuaj xyuas txog ob tus lej ntawm Doosan OEM—20010500002C thiab 20010500028—uas sawv cev rau cov khoom sib dhos tseem ceeb rau DX480, DX500, thiab DX520 cov platforms excavator hnyav. Kev tsom mus rau qhov no yog rauCQC TRACK(HELI MACHINERY MANUFACTURING CO., LTD.), ib lub chaw tsim khoom sib xyaw ua ke nrog ntau tshaj 20 xyoo ntawm kev tshwj xeeb hauv cov khoom siv hauv qab hnyav, thiab vim li cas nws txoj haujlwm ua lub hauv paus tseem ceeb rau cov kws tshaj lij thoob ntiaj teb uas tab tom nrhiav OEM-zoo chassis Cheebtsam ntawm cov nqi sib tw.

2. Kev Txheeb Xyuas Tus lej ntawm qhov chaw thiab Kev Sib Xws ntawm Lub Tshuab

Kev nkag siab txog kev sib raug zoo ntawm Doosan cov lej OEM thiab lawv cov ntawv thov tshuab sib xws yog qhov tseem ceeb rau kev nrhiav qhov tseeb. Cov lej uas tau hais hauv qhov kev tshuaj xyuas no xav tau kev txhais lus zoo raws li cov ntaub ntawv muaj, cov ntawv teev khoom, thiab cov ntaub ntawv sib txuas.

2.1 Cov lej tseem ceeb thiab lawv cov ntawv thov

Ib qho variant zoo sib xws, 200105-00002B, tau raug sau tseg tias yog lub rooj sib dhos carrier roller sib xws nrog DX420 thiab DX520 platforms, lees paub tias 200105xxxx tsev neeg ntawm cov lej ntu suav nrog ntau lub qauv Doosan excavator loj. Qhov kev sib txuas lus no yog qhov tshwj xeeb tshaj yog rau cov kws tshaj lij kev yuav khoom uas tswj cov nkoj sib xyaw thoob plaws 40–52 tuj.

Rau cov qauv Doosan DX500LCA/520LCA-HD, cov ntaub ntawv qhia txog kev teeb tsa hauv qab tsheb thauj khoom uas ruaj khov dua nrog 3 lub log sab saud (cov log nqa khoom), 9 lub log qis dua, thiab 3 lub tiv thaiv kev sib tw rau ib lub thav duab. Kev tsim qauv hauv qab tsheb thauj khoom hnyav no muaj cov qauv X-zoo li tus nrog lub caij nplooj ntoos hlav thiab lub log tsis sib dhos ua ke, lub thav duab tsheb thauj khoom ruaj khov, thiab cov txuas kaw uas ua rau nws tus kheej lubricating.

2.2 Cov Lus Qhia Txog Lub Tshuab Platform

Cov tshuab uas siv rau cov khoom siv thauj khoom no ua haujlwm hauv chav kawm hnyav 49–52 tuj, nrog rau cov lus qhia nram qab no:

Cov koob Doosan DX480/520LCA-K muaj qhov hnyav tshaj plaws hauv nws chav kawm thiab lub hauv qab ntev thiab dav heev, uas tso cai rau cov neeg teb xov tooj ua haujlwm nyuaj thiab hnyav nrog kev ruaj khov siab tshaj plaws. Cov koob DX520LCA-K crawler excavator, nrog qhov hnyav ua haujlwm ntawm 52,200 kg, tau tsim nrog cov yam ntxwv siab heev rau kev tsim khoom ntau dua, kev ruaj khov ntau dua ntawm qhov chaw, thiab cov nqi ua haujlwm qis dua.

2.3 Kev Txheeb Xyuas Tus Naj Npawb Cheebtsam Hauv Qab Tsheb

Rau cov neeg tsav tsheb thauj khoom thiab cov kws tshaj lij kev yuav khoom, kev suav cov khoom kom raug yog qhov tseem ceeb rau kev txiav txim kom raug. Cov ntaub ntawv pov thawj los ntawm ntau qhov chaw lees paub qhov ntau ntawm cov khoom hauv qab no rau Doosan DX480 thiab DX520:

Cov ntaub ntawv sau tseg txog plaub lub log sab saud (cov log nqa khoom) rau ib lub tshuab lees paub tias DX480 thiab DX520 cov tshuab khawb av siv ob lub log nqa khoom rau ib sab ntawm txoj kev. Rau qhov kev teeb tsa DX500LCA/520LCA-HD, muaj peb lub log sab saud rau ib sab, ua rau tag nrho rau lub rau ib lub tshuab. Qhov kev hloov pauv no qhia txog qhov tseem ceeb ntawm kev txheeb xyuas qhov kev teeb tsa hauv qab tsheb ua ntej xaj.

3. Kev Ua Haujlwm Engineering thiab Kev Tsim Kho Tshuab ntawm Carrier Rollers

3.1 Lub Luag Haujlwm

Lub rooj sib dhos ntawm lub log tsheb thauj khoom ua peb txoj haujlwm tseem ceeb uas cuam tshuam ncaj qha rau lub neej ntev ntawm lub tsheb thauj khoom:

1. Kev Taw Qhia Sab Sauv: Cov menyuam nqa khoom coj txoj saw hlau rov qab (sab saud) thaum nws mus los ntawm lub sprocket tsav rov qab mus rau pem hauv ntej idler. Tus qauv tsim ob-flange coj txoj saw hlau txuas kom ruaj ntseg, tiv thaiv kev plam sab thiab nplawm ntau dhau thaum mus ncig ceev ceev. Kev taw qhia kom zoo tswj hwm txoj kev sib dhos, tiv thaiv kev co sab nraud, thiab txo qhov hnav ntawm ob txoj saw hlau thiab cov hniav sprocket.

2. Kev Tswj Xyuas Qhov Ntshaw Dynamic: Thaum lub idler pem hauv ntej thiab lub cuab yeej kho qhov chaw tswj hwm qhov nro ntawm txoj kev, cov menyuam nqa khoom pab tswj kev hloov pauv ntawm qhov nro uas tshwm sim thaum lub tshuab nrawm, qeeb, lossis tig. Lub luag haujlwm no tseem ceeb heev thaum tig ceev ntawm cov chaw khawb av, qhov twg txoj kev sab saud muaj zog loj heev uas tuaj yeem ua rau derail yog tias tsis coj kom zoo.

3. Kev Txhawb Nqa Txoj Kev Sib Tw thiab Kev Tiv Thaiv Kev Ncab: Lub luag haujlwm tseem ceeb ntawm cov menyuam nqa khoom yog txhawb nqa txoj kev thiab tiv thaiv txoj kev sib tw kom tsis txhob sag ntau dhau, txo kev co thaum lub sijhawm txav mus los thiab tiv thaiv txoj kev kom tsis txhob swb mus rau sab. Txoj kev sag ntau dhau tuaj yeem ua rau txoj saw hlau kov lub thav duab ntawm txoj kev, ua rau hnav sai dua thiab ua rau kev tawm tsam.

4. Kev Tiv Thaiv Kab Mob: Cov menyuam nqa khoom siv cov txheej txheem kaw zoo heev los tsim kom muaj kev tiv thaiv zoo tiv thaiv cov av nkos, xuab zeb, thiab dej noo - cov kab mob feem ntau hauv kev khawb av thiab chaw khawb pob zeb. Qhov no tiv thaiv cov kabmob sab hauv thiab ua kom lub neej ua haujlwm ntev dua.

3.2 Cov Qauv Tsim Kho Vaj Tse

Ib lub rooj sib dhos ua tiav ntawm Doosan carrier roller muaj cov khoom hauv qab no:

Cov menyuam khiav ua raws li "welding → vertical CNC lathe precision machining" txheej txheem, tshem tawm cov kev ua yuam kev concentricity los ntawm kev ua haujlwm tom qab vuam thiab txhim kho qhov tseeb geometric thiab kev ruaj khov ua haujlwm.

4. Cov Lus Qhia Txog Khoom Siv thiab Cov Qauv Kev Kho Mob Kub

4.1 Kev Xaiv Khoom Siv

Cov menyuam nqa khoom zoo rau Doosan excavators yog tsim los ntawm cov hlau alloy qib siab xaiv rau lawv cov khoom muaj zog tshwj xeeb, toughness, thiab hnav tsis kam. Cov khoom siv feem ntau teev rau excavator track rollers yog 50Mn alloy steel (AISI 1050 sib npaug), ib qho carbon-manganese alloy siab uas paub txog kev ua kom tawv thiab hnav tsis kam.

Lub cev log yog forged los ntawm 50Mn puag ncig hlau nrog zoo hardenability, kom ntseeg tau tias cov qauv noob sib npaug thiab tshem tawm cov voids sab hauv uas yuav ua rau tsis ua haujlwm ua ntej lub sijhawm.

4.2 Cov Lus Qhia Txog Kev Kho Mob Kub

Kev ua tau zoo ntawm lub tsheb thauj khoom khiav yog nyob ntawm nws cov qauv kho cua sov:

Cov kab automation kho cua sov siv cov txheej txheem quenching tag nrho los tsim cov menyuam, ua tau raws li cov kev cai nruj rau cov khoom siv hauv kev khawb av. Rau lub cev menyuam, cov txheej txheem quenching thiab tempering ua ke nrog qhov nruab nrab zaus quenching nto ua kom muaj zog thiab hnav tsis kam, thaum lub ncej raug kho tib yam kom ua tiav qhov nyuaj ntawm HRC 52-60 nrog lub txheej tawv ntawm 3-6 hli.

4.3 Lub Peev Xwm Thauj Khoom thiab Cov Kev Ntsuas Kev Ua Tau Zoo

Cov khoom zoo uas tsim los ntawm cov ntaub ntawv zoo tuaj yeem siv tau ntev dua 20-30% dua li cov khoom pheej yig dua, ua rau muaj kev txuag nyiaj mus sij hawm ntev.
