Ukuqina Kwezinga Lokumba: I-Hitachi EX1800 / EX1900 Track Sprocket Wheel Assembly

1. Isingeniso: Umgogodla Wokumba Okusezingeni Eliphezulu

Emkhakheni wezimayini ezinkulu, ukumba amatshe, kanye nokwakhiwa kwezakhiwo ezisindayo, uchungechunge lwe-Hitachi EX1800 kanye ne-EX1900 lumelela isiqongo sokusebenza kahle kokumba imigodi ye-hydraulic. Njengoba isisindo sokusebenza sidlula amathani angu-180 metric kanye namandla okubamba amabhakede afinyelela kumamitha ayi-15 cubic, le mishini isebenza ngaphansi kwezimo ezingapheli—imithwalo enamandla kakhulu, izinto ezihudulayo, kanye nemijikelezo yokushintsha eqhubekayo.

I-Track Sprocket Wheel Assembly (ebizwa nangokuthi i-track chain sprocket assy) iyisici esibalulekile se-drivetrain esiguqula amandla e-hydraulic abe yi-traction. Emisebenzini yokumba ebhande lethusi laseChile, ezimayini zeplatinum zaseNingizimu Afrika, noma emasimini ensimbi aseRussia, ukuthembeka kwalesi simiso kuqondisa ngqo imigomo yokukhiqiza kanye nezindleko ngethani.

Lesi sihloko sinikeza ukuhlaziywa kobuchwepheshe okujulile kwenhlangano ye-sprocket yekhwalithi ye-OEM ekhonjwe ngezinombolo zezingxenye1028990,4451622, futhi4637264, ekhiqizwe ngaphansi kwezinqubo eziqinile zeI-CQC TRACK—okukhethekileifektri yomthombofuthiumenziizingxenye ze-EXC ezithwala ngaphansi kwenqola ezisindayo.

2. Imininingwane Yobuchwepheshe Nokushintshana

2.1 Ukuhlonza Ingxenye

Izinombolo ezintathu zezingxenye zihambisana nokwehluka kwe-sprocket assembly esetshenziswa kuwo wonke amapulatifomu e-Hitachi EX1800 kanye ne-EX1900:

• 1028990: Ngokuvamile ibhekisela ekuhlanganisweni kwesondo eliphelele le-sprocket (ihabhu + indandatho) yokulungiswa kwedrayivu yokugcina ethile.
• 4451622: Ngokuvamile ihlotshaniswa nendandatho ye-sprocket ehlukanisiwe noma ukuhlanganiswa kwamayunithi e-EX1900 emodeli yakamuva.
• 4637264: Ngokuvamile limelela ikhithi yesigaba se-sprocket noma indandatho yokuguguleka ye-bolt-on, okuvumela ukushintshwa kwensimu ngaphandle kokususa injini yokugcina yokushayela.

Lezi zingxenye zenzelwe ukuhlangana neyunithi yokunciphisa ukuhamba ye-Hitachi (ngokuvamile enesixhumi esinama-splined noma esinama-bolt) futhi zenzelwe amaketanga ethrekhi ane-pitch engu-317 mm noma engu-350 mm, kuye ngokuthi i-undercarriage ihlelwe kanjani.

2.2 Izici Zokwakha Ezinzima

Ngokungafani nezingxenye zomgubungeli zosayizi ophakathi, i-sprocket ye-EX1800/EX1900 yakhelwe ukumelana:

• Ukudluliselwa kwe-Torque Ephakeme: Amandla okujikeleza afinyelela ku-1,500 kN·m.
• Ukuguguleka Okukhulu: Ukuthintana okuqhubekayo nedwala eliqinile, insimbi, kanye nomthwalo osindayo.
• Ukulayisha Okushaqisayo: Kubangelwa indawo engalingani kanye nezinguquko ezisheshayo zendlela.

Ukuhlanganiswa ngokuvamile kungokwesakhiwo esihlukaniswe ngezigaba, esiqukethe izingxenye eziningi zamazinyo eziboshiwe (ngokuvamile izingxenye ezintathu kuya kwezinhlanu nge-sprocket ngayinye) ezingashintshwa ngazinye, okunciphisa kakhulu isikhathi sokulungisa kanye nezindleko zempahla yezingxenye ezisele.

3. Ukwelashwa Kwensimbi Nokushisa Kwezimo Zokumbiwa Kwezimayini

Ukuze ifaneleke njengengxenye ye-EXC yemoto engaphansi kwemoto esezingeni eliphezulu, i-sprocket kumele idlule imininingwane ejwayelekile yezinto ezibonakalayo.I-CQC TRACKisebenzisa inqubo yokukhiqiza ehambisana ne-ISO 9001:2015 kanye nemikhuba emihle kakhulu yezimboni zezimayini.

3.1 Ibanga Lezinto Ezibalulekile

• Insimbi Ehlanganisiwe: Insimbi ye-chromium-molybdenum ene-alloy ephezulu (isb., 40CrNiMo noma elinganayo) ekhethelwe ukuqina okujulile kanye nokumelana nokukhathala kokuthintana okugoqekayo.
• Izakhiwo Zomshini: Amandla okukhiqiza ≥ 900 MPa, amandla okudonsa ≥ 1,080 MPa, okuqinisekisa ubuqotho besakhiwo ngaphansi kwemithwalo ephezulu.

3.2 Iphrothokholi Yokwelapha Ukushisa

• Ngokuqinisa: Indandatho yonke ye-sprocket idlula ekuqiniseni nasekucimeni ukuze kufezwe ubulukhuni obufanayo be-core (35-40 HRC).
• Ukuqina Kwephrofayili Yamazinyo: Izinhlangothi zamazinyo kanye nerediyasi yezimpande kuqiniswa yi-induction kufinyelele ku-52-58 HRC kuze kube ngu-12-15 mm, okudala indawo engagugi ngenkathi kugcinwa umongo oqinile ukuze umunce imithelela.
• Ukulinganisela: Umjikelezo wokulinganisela olawulwayo unciphisa ukucindezeleka okusele futhi unciphise ingozi yokusabalala kwemifantu ezindaweni ezibandayo (isb., ukumbiwa kwemigodi yaseSiberia).

3.3 Ukuqinisekiswa Kwekhwalithi

Iqoqo ngalinye lokukhiqiza libhekene nalokhu:

• Ukuhlolwa kwe-Ultrasonic (UT): Ukuthola izikhala zangaphakathi noma okufakiwe ku-forging.
• Ukuhlolwa Kwezinhlayiya ZikaMagnetic (MPI): Ukuhlolwa okungu-100% kwendawo yezinyo kanye nemigodi yamabholidi.
• Ukuqinisekiswa Kobukhulu: Ukuqinisekiswa kwe-CMM kobubanzi bephimbo, iphrofayili yamazinyo, kanye nokunemba kwesiyingi sebhawodi kufinyelele ngaphakathi kuka-±0.5 mm.

4. Izidingo Zemakethe Yesifunda kanye Namaphrofayili Ohlelo Lokusebenza

I-Hitachi EX1800 kanye ne-EX1900 zisetshenziswa ezindaweni zokumba ezidinga kakhulu emhlabeni kanye nezindawo zokwakha ezisindayo. Ukuhlanganiswa kwe-sprocket kumele kuhambisane nemininingwane yokusebenza kwesifunda.

5. Ubuchwepheshe Bokukhiqiza:I-CQC TRACKnjengeFektri Yomthombo

Njengefektri ezinikele kanye nomkhiqizi wezingxenye ze-EXC ezithwala ngaphansi kwemoto ezisindayo, i-CQC TRACK iyazihlukanisa ngokuhlanganiswa okuqondile kanye nobuchwepheshe bobunjiniyela.

5.1 Amakhono Emboni

• Ukwakha Nokubumba: Izintambo zokwakha zangaphakathi ezikwazi ukukhiqiza ama-sprocket blanks afinyelela ku-2,500 mm ububanzi.
• Imishini ye-CNC: izikhungo zomshini ezine-axis ezi-5 zokufaka iphrofayili yamazinyo enembile kanye nokubhoboza imigodi yebholidi.
• Izinsiza Zokwelapha Ukushisa: Amaseli okuqinisa ukungeniswa okuzenzakalelayo anokuqapha izinga lokushisa ngesikhathi sangempela ukuqinisekisa ukujula kokuqina okuhambisanayo.
• Umugqa Wokumboza: Ukusetshenziswa kwe-polyurethane noma i-epoxy ehlala isikhathi eside yokumelana nokugqwala ezindaweni zasolwandle nezinomswakama ophezulu.

5.2 Ukusekelwa Kobunjiniyela

I-CQC TRACK inikeza:

• Ubunjiniyela Obubuyela Emuva: Amandla okuphinda ama-sprocket kusuka kumasampula agugile, okuqinisekisa i-geometry eqondile yamamodeli akudala.
• Ukwenza ngokwezifiso: Ukuguqulwa kwamaphrofayili ezinyo noma amaphethini ebholidi ukuze kuhambisane nokucushwa kokugcina okungekhona okujwayelekile.
• Imibhalo Yobuchwepheshe: Ukuhlinzekwa kwemidwebo yobukhulu, amaphrofayili obulukhuni, kanye nezitifiketi zezinto (EN 10204 3.1) ukuze kuhlangatshezwane nezidingo zokuthengwa.

5.3 Ukuhambisana kwe-OEM

Izinhlangano zezinombolo zezingxenye1028990, 4451622, 4637264zenzelwe ukufanisa noma ukudlula imininingwane yokuqala ye-Hitachi, okunikeza:

• Ukushintshana: Ukushintshana kwebhawodi ngqo ngaphandle kokuguqulwa.
• Ukushintshana Kwezingxenye: Ukuhambisana nama-bolts ezingxenye ze-OEM kanye nama-washer.

6. Ukuthuthukiswa Kwezindleko Zomjikelezo Wempilo

Kuma-mining fleet amakhulu, ukulungiswa kwe-subcar kumelela ingxenye enkulu yezindleko zokusebenza. Ukukhetha i-sprocket assembly efanele kuthinta:

• Ukugqokwa Kwezintambo Zomkhondo: Amazinyo e-sprocket aqiniswe kahle andisa impilo yokubopha ngokugcina ukuhlangana kwephimbo okulungile.
• Ukunciphisa Isikhathi Sokungasebenzi: Imiklamo ehlukaniswe ngezigaba ivumela ukushintshwa kwezingxenye zamazinyo ngazinye ngaphansi kwamahora ama-4, uma kuqhathaniswa nokushintshwa kokuhlanganiswa okugcwele okungathatha ishifti ephelele.
• Ukuphathwa Kwempahla: Ukubeka izingxenye zesitoko esikhundleni samasondo aphelele kunciphisa imali yempahla kanye nendawo yokugcina impahla.

7. Isiphetho: Ubunjiniyela Besikhathi Esiphezulu Sokusebenza

I-Hitachi EX1800 kanye ne-EX1900 zenzelwe ukukhiqiza, kodwa izingxenye zazo ezingaphansi kwenqola zinquma ukusimama kwalowo mkhiqizo. I-Track Sprocket Wheel Assembly—kungakhathaliseki ukuthi ibizwa ngokuthi i-1028990, 4451622, noma i-4637264—kumele ilethe ukuqina okungaguquguquki, ukulingana okunembile, kanye nokulungiswa okulula.

Ukubambisana nefektri ekhethekile yomthombo kanye nomkhiqizi ofana ne-CQC TRACK kuqinisekisa:

• I-Metallurgy Yezinga Lokumbiwa: Yenzelwe ukuguguleka kanye nokushayisana.
• Uchungechunge Lokuphakelwa Komhlaba Wonke: Izinhlelo zokufaka impahla ezilungiselelwe izikhungo zezimayini zesifunda (i-Antofagasta, iGoli, iYakutia, i-Alberta, njll.).
• Ukulandelela kanye Nesitifiketi: Imibhalo egcwele yokwanelisa amazinga okuthengwa kwezimayini.

Kubasebenzi bezimayini, abanikazi bemishini, kanye nabasabalalisi be-aftermarket, ukutshala imali ekuhlanganisweni kwe-sprocket ye-premium akuyona nje into yokufaka esikhundleni—kuyisinyathelo esihlakaniphile sokunciphisa izindleko ngethani nokwandisa ukusetshenziswa kwempahla.
