Mafotokozedwe Aukadaulo Okwanira: HITACHI ZX450/ZX470/ZX490 Excavator Track Idler Assembly / Guide Wheel Assembly (P/N: YA60041974) – OEM & ODM Wopanga: HELI (CQCTRACK)

1. Kuzindikira Zigawo ndi Kuphatikiza Machitidwe

Gulu la Track Idler Assembly, lomwe limatchedwanso kuti Track Guide Wheel Assembly (Nambala Yoyamba ya Gawo: YA60041974), ndi gawo la kutsogolo, lopangidwa mwaluso kwambiri lomwe limaphatikizidwa ndi makina oyendera pansi pa galimoto a HITACHI ZX450, ZX470, ndi ZX490. Lopangidwa ndi HELI (CQCTRACK) monga wogulitsa Zida Zoyambirira (OEM) komanso mnzake wa Wopanga Mapangidwe Oyambirira (ODM), chipangizochi ndi chitsogozo chenicheni komanso chomaliza cha mphamvu ya unyolo wa njanji ya mgodi wofukula. Kapangidwe kake ndi magwiridwe ake ndizofunikira kwambiri pakuwonetsetsa kuti chingwe cha njanji chili chokhazikika, kugwirira bwino nsapato za njanji, komanso kutumiza mphamvu moyenera panthawi yoyendetsa ndi kuzungulira.

2. Ntchito Zoyambira ndi Ntchito ya Kinematic

• Malangizo ndi Kulinganiza Unyolo wa Track: Amapereka malo olimba komanso ozungulira omwe amatsogolera bwino maulumikizidwe a unyolo wa track, kuonetsetsa kuti unyolowo ukuyenda bwino nthawi zonse pamene unyolo ukulowa m'njira yapamwamba, motero amaletsa kuyenda ndi kusokonekera kwa njanji.
• Kulamulira Mphamvu Yosinthasintha: Monga malo okhazikika a silinda yolumikizira ya hydraulic kapena yodzaza mafuta, choyimitsa chimatumiza mphamvu yosinthika kutsogolo ku unyolo wonse wa njanji. Kusunga mphamvu yoyenera ndikofunikira kwambiri pochepetsa kutayika kwa mphamvu, kuchepetsa "kuthyoka" kwa njanji, komanso kupewa kuwonongeka msanga kwa ma pini, bushings, ndi mano a sprocket.
• Kutaya Katundu Wokhudzana ndi Impact Load: Kumayamwa ndi kugawa katundu woyima ndi wopingasa pamene unyolo wa njanji umalumikizana panthawi yoyenda pa makina pamwamba pa malo osakhazikika, kuteteza chimango cha njanji ndi ma weld omangidwa ku kutopa kwa nkhawa.
• Kukhazikika kwa Gauge ya Pansi pa Gari: Kumagwira ntchito ngati nangula wa kapangidwe ka kutsogolo komwe kumatanthauzira ndikusunga gauge yolondola ya njanji (mtunda pakati pa mizere yapakati ya njanji zofananira), wofunikira kwambiri kuti makina azikhala olimba komanso kuti azitsatira mzere wowongoka.

3. Kapangidwe Kakang'ono ndi Uinjiniya Wazinthu

Njira yopangira ya HELI ya ODM/OEM yaYA60041974Kupanga kumaphatikizapo zitsulo zapamwamba komanso makina olondola:

• Wheel/Rim ya Idler: Yopangidwa ndi chitsulo chopangidwa ndi alloy (monga 50Mn kapena chofanana nacho). Malo oyendetsera galimoto amapangidwa ndi induction stirring kuti apeze kuuma kozama komanso kolamulidwa (nthawi zambiri kuuma kwa HRC 58-62, ndi kuuma kwa HRC 30-40), kuonetsetsa kuti palibe kuvulala komwe kumachitika chifukwa cha kukhudzana ndi track bushing pamene ikusunga mphamvu ya impact.
• Chipinda Cholumikizira ndi Shaft Chokhazikika: Chili ndi shaft yachitsulo champhamvu kwambiri, yokonzedwa ndi kutentha yomwe imapindidwa kapena kuyikidwa makiyi ndikukanikizidwa mu flange hub yopangidwa. Majenerali okhala ndi shaft amakhala osalala bwino mpaka a micron ndipo nthawi zambiri amakhala olimba kwambiri okhala ndi chrome kapena nitride kuti azitha kuwonongeka bwino komanso kupewa dzimbiri pamalo olumikizirana ndi bearing.
• Kapangidwe ka Bearing Kokhala ndi Mphamvu Yaikulu: Kamagwiritsa ntchito ma Bearings a Tapered Roller Bearings (TRBs) kapena ma Bearings a Double-Row Spherical Roller Bearings ofanana. Kapangidwe kameneka kamasankhidwa makamaka kuti kayang'anire katundu waukulu wa radial kuchokera ku kulemera kwa makina ndi katundu wolemera wa axial thrust wopangidwa panthawi yotembenuza mwamphamvu komanso ntchito yozungulira yomwe imachitika ndi ma excavator a ZX450-490 class.
• Dongosolo Lotsekera Zinthu Zambiri Lapamwamba: Lili ndi chisindikizo cha nkhope chozungulira chomwe chimaphatikizidwa ndi chisindikizo cha mbali yoyandama komanso choteteza fumbi chakunja cha multi-labyrinth. Dongosolo loteteza katatu ili lili ndi mafuta a lithiamu-complex okhala ndi kukhuthala kwakukulu, kupanikizika kwakukulu (EP) kuti apange chotchinga chosalowa madzi motsutsana ndi tinthu tating'onoting'ono tomwe timapanga zinthu (fumbi la miyala, silica) ndi kulowa kwa madzi, ngakhale pansi pa kusamba kwamphamvu.
• Zopangira Zosinthira: Zimaphatikizapo mphete zolimba komanso zophwanyika kapena zotchingira zosinthika zopangidwa ndi bronze yothira mafuta kapena chitsulo cholimba pamwamba. Izi zimalumikizana ndi chotchingira chosinthira cha chimango cha njanji, zomwe zimathandiza kuti chiziyenda bwino pamene chikupangidwa ngati zinthu zoteteza chidendene chapakati ndi kapangidwe ka chimango.
• Makonzedwe Opaka Mafuta: Amayikidwa ndi zolumikizira zamagetsi zamtundu wa hydraulic (monga ST-type) kuti zithandize kukonza bwino malo olumikizirana ndi malo otsetsereka.

4. Kuthekera kwa HELI (CQCTRACK) OEM/ODM Kupanga Zinthu

Pa msonkhano wa YA60041974, HELI imagwira ntchito motsatira malamulo okhwima a OEM ndi ODM:

• Kutsatira kwa OEM: Amapanga zinthu motsatira miyezo ya Hitachi Engineering Standards (HES), kuphatikizapo chitsimikizo cha zinthu zonse, kutsata miyezo, ndi kutsimikizira magwiridwe antchito, nthawi zambiri kuti ziperekedwe mwachindunji ku mizere yolumikizira ya Hitachi kapena ma netiweki ovomerezeka a magawo.
• Ukatswiri wa ODM: Umapereka ntchito zonse zopangira (DFM) ndi zomangamanga, kupereka mayankho okonzedwa mwamakonda monga kukweza zinthu, kuwonjezera chisindikizo, kapena kukonza kulemera kwa malo enaake ogwirira ntchito popanda kusokoneza zofunikira pakugwira ntchito.
• Kuyenda Kogwirizana kwa Kupanga: Kumagwiritsa ntchito njira yopangira yozungulira: Kapangidwe ka CNC forging die → kupanga yokha → kuziziritsa kolamulidwa → makina okhwima → kuchepetsa kupsinjika → kukonza komaliza → kukonza kutentha pogwiritsa ntchito kompyuta → kupukuta ndi kupukuta → kuyeretsa kwa ultrasound → kukhazikitsa mabearing/seal → kuyika chizindikiro cha laser → kuyesa komaliza.
• Kutsimikizira Ubwino ndi Kutsata Zinthu: Kumagwiritsa ntchito dongosolo lonse la lipoti la mayeso a zinthu (MTR). Gulu lililonse limayesedwa mosawononga (MPI/DPI), kutsimikizira kuuma kwa kuuma, kuyesa kuthamanga kwa chisindikizo, ndi kusanthula kwa torque yozungulira. Zigawo zimalembedwa ndi ma code apadera a malo kuti zitsatire bwino.

5. Mafotokozedwe Aukadaulo & Deta Yogwirira Ntchito

• Kukhulupirika kwa Miyeso: Kumagwirizana ndendende ndi Diameter yakunja (OD) yomwe Hitachi adatchula, Upana wonse, Diameter ya Bore, Kutalika kwa Flange, ndi Pattern ya Bolt.
• Kuchuluka kwa Mphamvu Yonyamula: Yopangidwa kuti ipitirire zofunikira za mphamvu yonyamula ya mndandanda wa ZX450-490, zomwe zimapangitsa kuti pakhale chitetezo chochepa malinga ndi ISO 10262 kapena miyezo yofanana ya makina osuntha nthaka.
• Kugwira Ntchito kwa Chisindikizo: Kuyesedwa kuti kupirire kumiza ndi kusamba ndi mphamvu motsatira ISO 3457 (kutseka kosasinthasintha) ndi mafuta ochepa kapena kulowa kwa zinthu zodetsa.
• Kulekerera Zachilengedwe: Yopangidwira kutentha kogwira ntchito kuyambira -25°C mpaka +80°C, yokhala ndi mafuta ndi zomatira zomwe zafotokozedwa moyenerera.

6. Kugwiritsa Ntchito, Kukonza & Kusinthasintha

• Kugwiritsa Ntchito Mwachindunji: Mitundu ya Hitachi ZX450LC, ZX470LCH, ZX490LCH, ndi mitundu yawo yosiyanasiyana.
• Kusinthana: Kulowa m'malo mwachindunji, m'malo mwa bolt-for-bolt pa cholumikizira choyambirira cha Hitachi YA60041974. Kufotokozera m'malo kuyenera kutsimikizira nthawi zonse kuchuluka kwa manambala a makina kuti musinthe mainjiniya.
• Kuyeza Kuvala ndi Moyo Wotumikira: Miyeso yofunika kwambiri ya kuvala ikuphatikizapo kuchepetsa OD ya mkombero ndi kuchepera kwa flange. Kuyeza pafupipafupi poyerekeza ndi zofunikira za fakitale ndikofunikira. Moyo wotumikira umakulitsidwa mwa kusunga mphamvu yoyenera ya njanji ndikutsuka zinyalala kuchokera m'bowo pakati pa idler ndi chimango cha njanji.
• Kusintha Kochokera ku Dongosolo: Kuti galimoto yonyamula katundu igwire bwino ntchito komanso kuti igwire bwino ntchito, kusintha galimoto yonyamula katundu kuyenera kuyesedwa pamodzi ndi momwe galimotoyo ilili (mapini ndi ma bushing), ma sprocket (malire kapena gulu lonse), ndi ma carrier rollers kuti apewe kuwonongeka mwachangu kwa zida zatsopano.

Mapeto

HITACHI YA60041974 Track Idler/Guide Wheel Assembly ya ZX450/ZX470/ZX490 excavators, yopangidwa ndi HELI (CQCTRACK), ikuwonetsa kugwirizana kwa OEM kulondola ndi kusinthasintha kwa kupanga kwa ODM. Kapangidwe kake, kozikidwa pa sayansi yapamwamba kwambiri ya zinthu, kutentha kwapamwamba, komanso njira yotsekera zinthu zambiri, imapereka kulimba ndi kudalirika kofunikira pa ntchito zovuta kwambiri zofukula ndi migodi. Monga wopanga wovomerezeka, HELI imawonetsetsa kuti gawo lofunika kwambiri la pansi pa galimoto silimangokwaniritsa komanso limatha kupitirira miyezo yolimba yokhazikitsidwa ndi Hitachi, kupatsa ogwiritsa ntchito gawo lomwe limatsimikizira kukhazikika kwa makina, kugwira ntchito bwino, komanso moyo wautali wa ntchito pamakina onse oyendera.
