HELI (CQCTRACK): ODM-Engineered Final Drive Wheel / Track Sprocket Assembly rau KOMATSU PC1250 Mining Excavators (Part No.21N2731191)

HELI (hu ua CQCTRACK), yog ib lub tuam txhab ODM (Original Design Manufacturing) thoob ntiaj teb uas ua haujlwm hnyav, tshwj xeeb hauv kev tsim kho thiab tsim cov khoom siv tsav tsheb tseem ceeb rau cov khoom siv khawb av zoo tshaj plaws. Cov ntaub ntawv kev siv tshuab no muab kev piav qhia txog peb lub Log Tsav Tsheb Kawg / Track Sprocket Assembly—ib qho kev daws teeb meem ua haujlwm siab uas tsim los ua qhov hloov pauv ncaj qha, zoo dua rau KOMATSU qhov lej 21N2731191, uas tau tsim tshwj xeeb rau KOMATSU PC1250 lub tshuab khawb av hnyav.

1. Txheej txheem cej luam khoom: Kev sib xyaw ua ke kawg tsav sprocket rau kev tsav tsheb hnyav

Lub Log Tsav Kawg/Sprocket Sib Dhos yog qhov sib txuas ntawm lub zog xa mus rau hauv lub tshuab khawb av. Rau cov tshuab khawb av zoo li Komatsu PC1250, cov khoom no tsis yog tsuas yog xa lub zog torque xwb; nws yuav tsum tiv taus kev ntxhov siab loj heev, kev poob siab loj heev los ntawm kev tsoo pob zeb tawg, thiab kev hnav tsis tu ncua. Yog tias qhov ua tsis tiav ntawm no ua rau lub tshuab tsis txav tau thiab cov nqi kho kim heev. HELI txoj hauv kev ODM sib xyaw ua ke lub sprocket thiab lub tshuab tsav kawg rau hauv ib qho kev sib dhos, kev ntseeg siab-optimized, tsim los ua kom zoo dua hauv qhov chaw khawb av hnyav tshaj plaws.

2. Kev Tshawb Fawb Txog Khoom Siv & ODM Engineering Methodology

Peb lub tswv yim tsim qauv yog ua ntej, tsom mus rau cov hom kev ua tsis tiav tshwj xeeb uas pom hauv PC1250-chav kawm mining operations.

A. Kev Tshawb Fawb Txog Metallurgical Foundation & Material Certification:
Lub rooj sib txoos yog tsim los ntawm ob qho sib txawv, daim ntawv thov tshwj xeeb alloy steels:

• Lub cev iav/Sprocket: Peb siv cov hlau sib xyaw ua ke xws li SAE 9310 (lossis DIN 18CrNiMo7-6). Cov hlau nickel-chromium-molybdenum no raug xaiv rau nws lub zog tseem ceeb (≥ 1100 MPa UTS) thiab kev ua kom tawv zoo, uas ua rau lub cev tob, tawv yam tsis cuam tshuam rau lub hauv paus ductile, tiv taus qaug zog uas tsim nyog rau cov hniav iav thiab cov sprocket lugs.
• Cov Gears & Shafts Sab Hauv: Rau cov khoom sib txuas siab no, peb yuav siv cov hlau uas tau nqus cua, carburizing-grade (piv txwv li, SAE 8620) kom ntseeg tau tias cov qauv huv si tsis muaj cov khoom uas tuaj yeem pib ua rau pitting lossis spalling.
• Txhua yam khoom siv nkag los tau ntawv pov thawj nrog cov ntawv qhia kev kuaj ntawm lub Hoobkas thiab raug kuaj xyuas spectrographic hauv tsev.

B. Kev Forging thiab Kev Siv Tshuab Rough Machining:
Cov ntsiab lus tseem ceeb ntawm cov qauv pib ua cov khoom seem uas raug tsim los ntawm kev tuag. Cov txheej txheem no:

• Ua kom cov Grain Flow sib phim raws li cov duab ntawm cov hniav iav thiab cov sprocket lugs, ua rau lub neej qaug zog ntev dua 2-3 npaug piv rau lwm cov kev xaiv uas siv tshuab los ntawm barstock.
• Tshem tawm qhov porosity sab hauv & txhim kho qhov ceev, tsim kom muaj cov qauv zoo sib xws uas muaj peev xwm tiv taus kev thauj khoom siab yam tsis muaj kev tawg sab hauv.

C. Kev Ua Haujlwm CNC Precision & Gear Manufacturing:
Cov khoom ua los ntawm cov hlau forged thiab cov khoom ua los ntawm cov hlau normalized raug siv ntau lub tshuab CNC machining thiab kev txiav iav tshwj xeeb.

• Kev Tsim Cov Hniav Iav: Cov hniav iav tsav kawg raug txiav siv CNC gear hobbling ua raws li kev sib tsoo profile kom ua tiav AGMA Class 11 lossis siab dua qhov tseeb. Qhov no ua kom muaj kev sib txuas zoo meej nrog cov iav planetary sab hauv, txo qis suab nrov, tsim cua sov, thiab kev ntxhov siab hauv zos.
• Kev Txhim Kho Cov Hniav Sprocket: Cov hniav sprocket sab nraud raug milled nrog cov qauv hloov pauv thiab cov hauv paus hniav zoo. Peb tus qauv ODM yuav suav nrog cov qauv hniav tsis sib xws kom tswj tau qhov kev faib khoom tsis sib xws thaum lub sijhawm sib koom thiab sib cais, txo qhov kev ntxhov siab siab tshaj plaws.
• Kev Siv Lub Hub & Interface Machining: Lub mounting hub, splines (lossis precision bolt circle), thiab cov nplaim seal-running surfaces yog finish-machined rau qhov kam rau siab ntawm IT6 lossis zoo dua. Qhov no lav qhov concentricity zoo meej, tshem tawm qhov tsis sib npaug, thiab ua kom muaj qhov interface tsis xau nrog lub tsev tsav kawg.

D. Kev Kho Mob Kub Ntau Qib Uas Muaj Kev Cai:
Cov cheeb tsam sib txawv ntawm lub rooj sib txoos raug hloov kho raws li cov txheej txheem thermal.

1. Kev Siv Cov Roj Sib Tsoo Sib Nraus: Tag nrho lub cev iav/sprocket raug tswj los ntawm lub khoos phis tawj, cov txheej txheem siv cov roj sib tsoo sib nraus sib nraus.
2. Kev Tua Hluav Taws Xob Siv Roj Siab Siab: Kev tswj hwm, kev tua hluav taws xob siv roj siab siab txo qhov kev cuam tshuam ntawm thermal thaum ua tiav qhov xwm txheej martensitic xav tau.
3. Kev Kho Mob Cryogenic (Xaiv tau rau Kev Pabcuam Hnyav): Rau qhov ruaj khov tshaj plaws thiab tiv taus kev hnav, cov khoom yuav raug kho kom tob tob kom hloov cov austenite uas khaws cia rau hauv martensite.
4. Ob Chav Tempering: Cov txheej txheem tempering ob theem txo cov kev ntxhov siab sab hauv thiab teeb tsa cov khoom siv kho tshuab kawg.
   • Cov Lus Qhia Txog Qhov Tshwm Sim:
     • Qhov tob ntawm cov hniav iav/Sprocket: 7.0 – 8.5 hli ntawm 550 HV.
     • Qhov Nyuaj Ntawm Qhov Chaw: 60 - 64 HRC.
     • Core Hardness & Toughness: 38 - 42 HRC nrog cov nqi Charpy V-notch siab.

E. Kev Sib Dhos, Kev Sib Kaw & Kev Sib Koom Ua Zaum Kawg:
Cov iav sab hauv planetary, bearings, thiab cov foob ua haujlwm siab uas tau sib sau ua ke hauv chav huv uas tswj tau huab cua.

• Sealing System: Peb siv cov labyrinth seals ua ke nrog cov khoom siv hnyav, ntau daim di ncauj radial seals tsim los ntawm hydrogenated nitrile butadiene roj hmab (HNBR) rau kev tiv taus cua sov, abrasives, thiab roj nplua nyeem tawg.
• Kev Siv Lubrication: Cov khoom sib dhos tau ntim nrog cov roj iav ua haujlwm siab, siab heev (EP) hluavtaws uas tau teev tseg rau cov ntawv thov khawb av.

3. Kev Pov Thawj Zoo thiab Kev Ua Haujlwm Zoo hauv Kev Khawb Av

Txhua lub rooj sib txoos raug rau ib qho kev lees paub tseeb:

1. Kev Ntsuas Geometric & Dimensional Metrology: Kev tshuaj xyuas tag nrho 3D CMM lees paub qhov geometry ntawm cov hniav iav, sprocket pitch, hub dimensions, thiab kev sib dhos ua ke.
2. Kev Tshuaj Xyuas Qhov Nyuaj & Microstructure: Kev txheeb xyuas qhov tob ntawm cov ntaub ntawv los ntawm kev sim micro-hardness thiab kev kuaj xyuas metallographic ntawm cov qauv coupons.
3. Kev Ntsuas Tsis Ua Rau Puas Tsuaj (NDT): 100% MPI ntawm txhua qhov chaw tseem ceeb thiab 100% UT ntawm cov chaw muaj kev ntxhov siab siab (cov hauv paus hniav, cov hub fillets).
4. Kev Kuaj Xyuas Kev Khiav thiab Kev Ua Haujlwm: Txhua chav tsev raug kuaj xyuas ib lub voj voog khiav uas tau thauj khoom ntawm lub tshuab kuaj uas ua qauv qhia txog lub zog ua haujlwm thiab qhov ceev. Qhov kev kuaj no xyuas kom meej tias:
   • Kev ua haujlwm du thiab ntsiag to.
   • Tsis muaj roj xau.
   • Kev thauj khoom ua ntej thiab qhov kub nce kom raug.

4. Qhov Zoo ntawm HELI (CQCTRACK) ODM rau Cov Tub Rog Khawb Av

• Kev Tsim Kho Kom Muaj Kev Ntseeg Tau: Peb tsim lub sprocket thiab qhov kawg drive interface ua ib qho system, tshem tawm qhov tsis sib xws thiab cov ntsiab lus tsis muaj zog pom muaj nyob rau hauv cov khoom sib cais.
• Lub Neej Kwv Yees Tau Hauv Cov Chaw Sib Txhuam: Kev sib xyaw ua ke ntawm cov hlau zoo tshaj plaws, kev ua kom tawv tob, thiab cov qauv iav/sprocket zoo tshaj plaws ua rau lub neej kev pabcuam ntev dua, kwv yees tau, txo cov sijhawm tsis ua haujlwm uas tsis tau teem sijhawm tseg.
• Kev Hloov Ncaj Qha nrog Cov Lus Qhia Txhim Kho: Tsim los rau kev sib pauv tsis muaj kev sib txuas thaum suav nrog cov khoom siv thiab kev txhim kho tsim los ntawm cov ntaub ntawv hauv daim teb los ntawm cov ntawv thov khawb av.
• Kev Tswj Xyuas Kev Tsim Khoom Ntsug Tag Nrho: Txij li kev sib tsoo mus rau kev sib dhos zaum kawg, peb txoj kev tswj hwm hauv tsev ua kom muaj kev taug qab, kev ruaj ntseg ntawm cov khoom xa tuaj, thiab kev sib xws, zoo li qib kev khawb av.
