1. Isifinyezo Esiphezulu: I-Heli CQCTRACK njengoMkhiqizi Womthombo Ochwepheshe Wezingxenye Ezingaphansi Kwezinqola Ze-KOMATSU Mini Excavator

Embusweni oncike ekuqondeni kwemisebenzi yokumba i-mini kuya kwephakathi (iklasi lamathani angu-1-13), i-track roller assembly—ebizwa ngokuthi i-track bottom roller noma i-lower roller—imelela isici esiyinhloko esithwala umthwalo ngaphakathi kohlelo lwe-track carriage. Le ngxenye yenza umsebenzi obalulekile wokusekela isisindo somshini ogcwele, isabalalisa ingcindezi ethwala umhlaba ngokulinganayo kulo lonke uchungechunge lwe-track, iqondise i-track chain kahle ohlakeni lwe-track carriage, inciphise ukungqubuzana phakathi kwezixhumanisi ze-track kanye nesakhiwo se-track carriage, futhi imunce ukushaqeka okuvela endaweni engalingani ukuze kuthuthukiswe ukuzinza komshini kanye nenduduzo yomqhubi. Kumapulatifomu e-KOMATSU PC80, PC90, PC100, PC120, kanye ne-PC130—ama-excavator aguquguqukayo asetshenziswa kabanzi ekwakheni amadolobha, ekuhleleni insimu, ezinsizeni, ekuthuthukisweni kwengqalasizinda, kanye nasezinhlelweni zokuhambisa umhlaba ezilula—i-track roller assembly imele njengengxenye ebalulekile enquma ukuzinza komshini, ukuhambisana kwe-track, kanye nokuphila isikhathi eside kwe-track carriage iyonke.

Imishini ye-Heli (i-CQCTRACK) izisungule njengomkhiqizi ohamba phambili womthombo wobungcweti kanye nomhlinzeki wezingxenye ze-undercarriage zezinhlelo zokusebenza ze-KOMATSU mini excavator. Njengomkhiqizi ozinikele, i-CQCTRACK isebenza ngaphakathi kwe-ecosystem ebanzi ye-HELI Group, ihlinzeka ngengqalasizinda edingekayo, ikhono le-R&D, kanye nezinhlelo zokuphatha ikhwalithi zokukhiqiza izingxenye ze-undercarriage ezisezingeni lomhlaba. Leli phepha elimhlophe lobuchwepheshe lihlinzeka ngokuhlaziywa okuphelele kobunjiniyela be-KOMATSU 820220032, 2033000110, 2033000111, 2033000140, 20E30K1580, kanye ne-22B3000010 Track Roller Assemblies, eyenzelwe ngqo amapulatifomu e-PC80-PC130 series excavator kanye nezinhlobo zawo.

Ngokuhlanganisa isayensi yezinto eziqinile (kusetshenziswa ama-alloy asezingeni eliphezulu njengezinsimbi ze-50Mn, 40MnB, kanye ne-35MnB), ubuchwepheshe bokubumba obuqinile obuvaliwe obunokuhamba okusanhlamvu okulungiselelwe, izinqubo zokwelapha ukushisa ezithuthukisiwe ezifinyelela ama-gradienti obuqinile obuhle kakhulu (ubuso be-52-58 HRC obunomongo oqinile, ukujula kwecala elingu-8-12mm), ukwakheka kokuvala okunezigaba eziningi okuqinisekiswe ukumelana nokungcola, kanye nezinqubo zokukhiqiza eziqinisekisiwe ze-ISO 9001:2015, i-Heli CQCTRACK inikeza izinhlangano ze-track roller ezifinyelela ukulingana kokusebenza okubhaliwe—nangezilinganiso ezithile ngale—kwezincazelo zemishini yokuqala.

Kwabochwepheshe bokuthenga, onjiniyela bokulungisa izimoto, kanye nabaphathi bemishini abafuna ukwandisa izindleko zobunikazi zemikhumbi yabo emincane ye-KOMATSU PC-series esebenza ekwakheni nasekulungiseni imvelo, lo mbhalo usebenza njengomhlahlandlela wobuchwepheshe oqondile wokubhekisela kanye nokuthola ulwazi.

2. Ukuhlonza Iphothifoliyo Yomkhiqizo kanye ne-Cross-Reference Matrix

Ukuqinisekisa ukunemba kokuthengwa kanye nokuhlanganiswa okungenamthungo ezinhlelweni zezimoto ezingaphansi kwemoto ezikhona, i-matrix yokuhlonza elandelayo ebanzi ichaza iphothifoliyo ephelele yezingxenye ezimbozwe ngaphansi kwale ncazelo.

2.1 Ukuhlanganiswa Kwesistimu ngaphakathi Kokuhlanganiswa Kwezinqola Ezingaphansi Kwemoto

I-Track Roller Assembly ayisebenzi njengesakhi esihlukanisiwe kodwa yakha isakhi esibalulekile esithwala umthwalo ngaphakathi kohlelo oluhlanganisiwe lwe-subcarriage:

• Ukwakhiwa Kwezinqola Ezingaphansi Kwemoto: Ama-roller ethrekhi afakwa ohlakeni lwe-track roller ngokusebenzisa ama-bracket okufaka i-shaft, abekwe phansi kwe-track ukuze asekele isisindo somshini futhi aqondise uchungechunge lwethrekhi.
• Umongo Wokusebenza: Lawa ma-roller athwala isisindo esiphelele sokusebenza kwe-excavator, esabalalisa ingcindezi ethwala umhlabathi futhi aqinisekise ukuzinza komshini ngesikhathi sokumba, ukuphakamisa, kanye nokusebenza kokuhamba. Imizimba yama-roller ensimbi eqinile kanye nemishayo enamandla amakhulu zenzelwe ukusekela isisindo esiphelele somshini futhi zimunce imithwalo yomthelela onamandla.
• Ukucushwa kweFlange: Kuye ngokuthi ikuphi ngaphakathi kwenqola engaphansi, ama-roller angaba yi-single-flange (afakwe ezindaweni zangaphandle) noma abe yi-double-flange (afakwe ezindaweni zangaphakathi ukuze anikeze isiqondiso esiseceleni).
• Ukucushwa Kokufaka: I-assembly inezindawo zokufaka ezisebenza ngomshini onembile (iziphetho zeshaft ezinezimbobo zebholidi) ezibopha i-roller ohlakeni lwethrekhi ukuze ifakelwe indawo eqondile eyakhelwe ngobukhulu besitayela se-OEM ukuze ifakelwe indawo ngokushesha ngebholidi kusetshenziswa amathuluzi ajwayelekile okusebenzela.

3. Ukwakhiwa Kobunjiniyela: I-Anatomy ye-Heli CQCTRACK KOMATSU PC80-PC130 Mini Excavator Track Roller Assemblies

Ukuphila isikhathi eside kokusebenza kwanoma iyiphi i-track roller assembly esebenza kuzinhlelo zokusebenza zomgubhu omncane wobungcweti kunqunywa ukusebenzisana okuhlangene kwezinhlelo ezincane ezinhlanu ezibalulekile zobunjiniyela: isakhiwo segobolondo le-roller, i-shaft metallurgy, uhlelo lokuthwala, ukwakheka kokuvala, kanye nohlelo lokugcoba. Onjiniyela be-Heli CQCTRACK ngayinye yalezi zinhlelo ezincane ngokunemba okufanele isicelo se-excavator sekilasi esingu-1-13 ton ezimweni zokusebenza ezahlukahlukene.

• Ukwakheka kwe-closed-die ngaphansi kokucindezela okunembile kubumba i-billet, okudala ukwakheka okuhlukile kokusatshalaliswa kokugeleza kwefayibha yezinto zangaphakathi okulandela i-roller contour.
• I-Flash iyasikwa, futhi isikhala esingenalutho esibunjiwe sihlolwa ngokubonakalayo.

4.2.3 Inqubo Yokwelapha Ukushisa

I-Heli CQCTRACK isebenzisa inqubo yokwelapha ukushisa enezigaba ezimbili ukuze kufezwe izakhiwo ezinhle kakhulu zemishini:

Isigaba 1: Ukucima Nokusheshisa (Q+T)

• Ukuqinisa: Umzimba we-roller ushiswa kuze kufike ezingeni lokushisa elibucayi ukuze kuguqulwe isakhiwo esincane.
• Ukucima: Ukupholisa okusheshayo kuguqula isakhiwo esincane sibe yi-martensite—isakhiwo esiqinile, esingagugi.
• Ukushisa: Ukushisa kabusha okulawulwayo kunciphisa ukucindezeleka kwangaphakathi ngenkathi kugcina ukuqina kwengaphakathi.

Isigaba 2: Ukuqina Kokungeniswa / Ukucima Ubuso

• Ukuqina Okukhethiwe: Ukuqina kokufakwa komoya kudala ikesi elijulile, eliqinile njalo ebusweni obugijimayo kanye nezinhlangothi ze-flange—ngokuvamile i-HRC52-58 enobubanzi obungu-8mm-12mm.
• Ukucubungula Okulawulwa Yikhompyutha: Zonke izinhlaka ziqashwa ngedijithali ukuqinisekisa ukujula kwecala okuhambisanayo.
• Imininingwane Efinyelelwe: Ubulukhuni bomphezulu 52-58 HRC kanye nokujula kwekesi 8-12mm.

Ithebula 4: Imininingwane Yokuqina—I-KOMATSU PC80-PC130 Track Roller Assembly
