HITACHI YA60041974 ZX450 ZX470 ZX490 Track Idler Assy / Track Guide Log Sib Dhos–Lub tshuab khawb hnyav Track chassis Cheebtsam OEM&ODM chaw tsim khoom-HELI(cqctrack)

Cov Lus Qhia Txog Kev Siv Tshuab: HITACHI ZX450/ZX470/ZX490 Excavator Track Idler Assembly / Guide Wheel Assembly (P/N: YA60041974) - OEM & ODM Chaw Tsim Khoom: HELI (CQCTRACK)

1. Kev Txheeb Xyuas Cheebtsam & Kev Sib Koom Ua Ke ntawm Lub Tshuab

Lub Rooj Sib Tham Idler, uas hloov pauv tau hu ua Track Guide Wheel Assembly (Tus lej seem qub: YA60041974), yog lub hauv ntej-kawg, precision-engineered chassis Cheebtsam integral rau lub undercarriage system ntawm HITACHI ZX450, ZX470, thiab ZX490 qauv hnyav-duty excavators. Tsim los ntawm HELI (CQCTRACK) ua tus neeg muab khoom qub (OEM) thiab tus khub tsim qauv qub (ODM), lub rooj sib txoos no yog qhov kev taw qhia mus tom ntej thiab qhov kawg ntawm kev nruj rau txoj saw hlau ntawm lub excavator. Nws txoj kev tsim thiab kev ua tau zoo yog qhov tseem ceeb rau kev ua kom ruaj khov ntev, kev sib koom ua ke ntawm txoj hlua khau kom zoo, thiab kev xa hluav taws xob zoo thaum lub sijhawm tsav thiab kev sib hloov rov qab.

2. Cov Haujlwm Ua Haujlwm Tseem Ceeb & Lub Luag Haujlwm Kinematic

• Kev Taw Qhia thiab Kev Sib Tov ntawm Cov Hlau Sib Tsoo: Muab ib qho chaw ruaj khov, tig tau uas coj cov khoom sib txuas ntawm cov hlau sib dhos kom meej, ua kom muaj kev sib txuas axial tas mus li thaum cov hlau nkag mus rau hauv txoj kev thauj khoom sab saud, yog li tiv thaiv kev taug kev sab nraud thiab kev tawm ntawm txoj kev.
• Kev Tswj Xyuas Kev Nruj Nruj: Raws li qhov chaw khi rau lub tog raj kheej hydraulic lossis roj-filled tensioning track, lub idler xa cov zog mus tom ntej mus rau tag nrho cov saw hlau. Kev tswj hwm qhov nro zoo tshaj plaws yog qhov tseem ceeb rau kev txo qis kev poob zog, txo cov kab "snap" lossis whip, thiab tiv thaiv kev hnav ua ntej ntawm cov pins, bushings, thiab cov hniav sprocket.
• Kev Tshem Tawm Lub Hnyav Uas Cuam Tshuam: Nqus thiab faib cov khoom hnyav thawj zaug ntsug thiab kab rov tav thaum txoj saw hlau sib cuag thaum lub tshuab mus ncig ntawm cov chaw tsis sib xws, tiv thaiv lub thav duab txoj kev thiab cov qauv vuam los ntawm kev qaug zog ntawm kev ntxhov siab.
• Kev Ruaj Ntseg ntawm Lub Tsheb Thauj Khoom: Ua haujlwm ua lub hauv paus ruaj khov uas txhais thiab tswj qhov ntsuas kev sib tw kom raug (qhov deb ntawm cov kab nruab nrab ntawm cov kev sib tw sib luag), tseem ceeb rau kev ruaj khov ntawm lub tshuab thiab kev taug qab ncaj.

3. Kev Tsim Kho Kom Paub Ntxiv & Kev Tsim Khoom Siv

HELI txoj kev tsim khoom ODM/OEM rauYA60041974kev sib dhos ua ke suav nrog kev ua hlau metallurgy thiab kev ua haujlwm raug:

• Lub Log Idler/Rim: Ua los ntawm cov hlau forged thiab normalized alloy steel (piv txwv li, 50Mn lossis sib npaug). Qhov chaw khiav dej num raug kev kho kom tawv kom ua tiav qhov nyuaj, tswj tau qhov nyuaj (feem ntau qhov nyuaj ntawm qhov chaw ntawm HRC 58-62, nrog rau qhov nyuaj ntawm HRC 30-40), kom ntseeg tau tias muaj kev tiv thaiv kev sib txhuam ntau heev tiv thaiv kev sib cuag ntawm txoj kev thaum tseem khaws lub zog cuam tshuam.
• Lub Hub & Ncej Sib Txuas Ua Ib Ke: Muaj lub ncej hlau sib xyaw ua ke uas muaj zog heev, kho cua sov uas yog splined lossis keyed thiab nias rau hauv lub hub flange forged. Cov ntawv xov xwm ntawm lub ncej bearing yog precision-ground rau micron-level tolerances thiab feem ntau hard chrome plated lossis nitrided rau kev hnav zoo dua thiab tiv taus corrosion ntawm cov npoo sib cuag ntawm cov bearing.
• Kev Teeb tsa Bearing Muaj Peev Xwm Loj: Siv ob khub sib phim ntawm cov kabmob loj Tapered Roller Bearings (TRBs) lossis Double-Row Spherical Roller Bearings. Kev teeb tsa no yog xaiv tshwj xeeb los tswj cov khoom thauj radial loj heev los ntawm qhov hnyav ntawm lub tshuab thiab cov khoom thauj axial loj heev uas tsim thaum lub sijhawm tig thiab kev ua haujlwm ntawm sab ntawm ZX450-490 chav kawm excavators.
• Lub Tshuab Sealing Ntau Yam Txheej Txheem: Muaj lub foob radial ntsej muag ua ke nrog lub foob sab ntab thiab lub tiv thaiv plua plav sab nraud ntau lub labyrinth. Lub tshuab tiv thaiv peb npaug no muaj cov roj lithium-complex uas muaj viscosity siab, siab heev (EP) los tsim kom muaj kev thaiv tsis pub cov khoom me me (hmoov av, silica) thiab cov kua nkag mus, txawm tias nyob hauv qhov chaw ntxuav siab.
• Cov Cheebtsam Sib Txuas Kev Kho: suav nrog cov nplhaib tawv thiab cov nplhaib hnav hauv av lossis cov bushings swb hloov tau ua los ntawm cov tooj dag sintered uas muaj roj lossis cov hlau uas tawv saum npoo. Cov no sib txuas nrog cov swb hloov kho ntawm lub thav duab, ua rau kev txav mus los du thaum tsim los ua cov khoom siv los tiv thaiv lub hauv paus idler thiab cov qauv thav duab.
• Kev Siv Lubrication: Muaj cov roj hydraulic-style grease fittings (piv txwv li, ST-hom) los pab txhawb kev saib xyuas niaj hnub ntawm ob qho chaw tseem ceeb ntawm lub cev thiab cov nplaim sliding bushing.

4. HELI (CQCTRACK) OEM/ODM Kev Muaj Peev Xwm Tsim Khoom

Rau YA60041974 sib dhos, HELI ua haujlwm raws li cov txheej txheem OEM thiab ODM nruj:

• Kev Ua Raws Cai OEM: Tsim cov khoom raws li Hitachi Engineering Standards (HES) raws nraim, suav nrog daim ntawv pov thawj tag nrho cov khoom siv, kev ua raws li qhov ntev, thiab kev lees paub kev ua tau zoo, feem ntau yog rau kev xa khoom ncaj qha rau Hitachi cov kab sib dhos lossis cov khoom siv tau tso cai.
• Kev Paub Txog ODM: Muab kev tsim qauv rau kev tsim khoom (DFM) thiab kev pabcuam tsim khoom tiav, muab cov kev daws teeb meem xws li kev hloov kho cov khoom siv, kev txhim kho lub foob, lossis kev ua kom qhov hnyav zoo rau cov chaw ua haujlwm tshwj xeeb yam tsis muaj kev cuam tshuam rau cov lus qhia ua haujlwm.
• Kev Tsim Khoom Ua Ke: Siv cov txheej txheem tsim khoom kaw-voj: CNC forging tuag tsim → automated forging → tswj kev txias → kev ua haujlwm tsis zoo → kev txo kev ntxhov siab → kev ua tiav machining → kev kho cua sov computer → sib tsoo & honing → kev ntxuav ultrasonic → kev teeb tsa bearing / foob tsis siv neeg → laser cim → kev sim zaum kawg.
• Kev Paub Zoo & Kev Taug Qab Tau: Siv Daim Ntawv Qhia Txog Kev Ntsuas Khoom Siv (MTR) tag nrho. Txhua pawg khoom raug kuaj tsis ua puas tsuaj (MPI/DPI), kev txheeb xyuas qhov tob ntawm qhov tawv, kev kuaj lub zog ntawm lub foob, thiab kev tshuaj xyuas lub zog tig. Cov khoom muaj cim nrog cov lej tshwj xeeb rau kev taug qab tau tag nrho.

5. Cov Lus Qhia Txog Kev Siv Tshuab & Cov Ntaub Ntawv Kev Ua Haujlwm

• Kev Ncaj Ncees ntawm Qhov Ntev: Ua raws li Hitachi qhov tau teev tseg Sab Nraud Txoj Kab uas hla (OD), Dav Tag Nrho, Txoj Kab uas hla ntawm lub qhov, Qhov Siab ntawm lub flange, thiab Tus Qauv Bolt.
• Kev Ntsuas Kev Thauj Khoom Dynamic: Tsim los kom dhau qhov yuav tsum tau ua rau ZX450-490 series, suav nrog qhov tsawg kawg nkaus kev nyab xeeb raws li ISO 10262 lossis cov qauv zoo sib xws rau cov tshuab txav av.
• Kev Ua Haujlwm ntawm Lub Qhov (seal): Sim kom tiv taus kev sib xyaw thiab kev ntxuav siab raws li ISO 3457 (static sealing) nrog tsawg kawg nkaus roj tawm lossis cov pa phem nkag.
• Kev Tiv Thaiv Ib Puag Ncig: Tsim los rau qhov kub thiab txias ua haujlwm ntawm -25 ° C txog + 80 ° C, nrog rau cov roj thiab cov khoom sib xyaw ua ke tau teev tseg raws li qhov tsim nyog.

6. Daim Ntawv Thov, Kev Txij Nkawm & Kev Hloov Pauv

• Daim Ntawv Thov Ncaj Qha: Hitachi cov qauv ZX450LC, ZX470LCH, ZX490LCH, thiab lawv cov koob sib txawv.
• Kev Hloov Tau: Ib qho kev hloov ncaj qha, ntsia hlau rau ntsia hlau rau thawj Hitachi YA60041974 sib dhos. Kev sib txuas lus yuav tsum ib txwm txheeb xyuas cov lej ntawm lub tshuab rau kev hloov kho engineering.
• Kev Ntsuas Kev Hnav thiab Lub Neej Ua Haujlwm: Qhov tseem ceeb ntawm kev hnav suav nrog kev txo qis OD ntawm lub log thiab kev nyias nyias ntawm qhov dav ntawm lub flange. Kev ntsuas tsis tu ncua raws li cov lus qhia ntawm lub Hoobkas yog qhov tseem ceeb. Lub neej ua haujlwm tau zoo tshaj plaws los ntawm kev tswj hwm qhov nruj ntawm txoj kev thiab ntxuav cov khib nyiab ntawm qhov sib txawv ntawm lub idler thiab txoj kev.
• Kev Hloov Kho Raws Li Lub Tshuab: Rau kev txuag hluav taws xob thiab kev ua tau zoo tshaj plaws, kev hloov pauv idler yuav tsum tau soj ntsuam ua ke nrog rau qhov xwm txheej ntawm txoj saw hlau (pins & bushings), sprocket (rims lossis tag nrho cov khoom sib dhos), thiab cov menyuam nqa khoom kom tsis txhob hnav sai sai rau cov khoom tshiab.
