I-HELI (ebizwa ngokuba yi-CQCTRACK), inkokheli yehlabathi ye-ODM (Original Design Manufacturing) kwizisombululo eziphantsi kwesithuthi esinzima, igxile kubunjineli nasekuveliseni iindibano zokuqhuba ezibalulekileyo zezixhobo zemigodi ezikumgangatho ophezulu. Le fayile yobugcisa inika inkcazelo epheleleyo ye-Final Drive Wheel / Track Sprocket Assembly yethu—isisombululo esidibeneyo ngokupheleleyo, esisebenza kakuhle esenzelwe indawo ethe ngqo, ekumgangatho ophezulu yenombolo yenxalenye ye-KOMATSU engu-21N2731191, eyenzelwe ngokukodwa i-KOMATSU PC1250 heavy-duty mining crawler excavator.

1. Isishwankathelo seMveliso: I-Integrated Final Drive Sprocket ye-Severe-Duty Propulsion

I-Final Drive Wheel/Sprocket Assembly yindibaniselwano yokudluliselwa kwamandla kwi-crawler excavator. Kwiimashini zodidi lwemigodi ezifana neKomatsu PC1250, eli candelo alidlulisi nje i-torque; kufuneka limelane noxinzelelo olukhulu lwe-torsional, imithwalo yomothuko omkhulu ngenxa yokunyathela phezu kwelitye eliqhushumbisiweyo, kunye nokuguga okungapheliyo. Ukungaphumeleli apha kubangela ukungashukumi ngokupheleleyo komatshini kunye neendleko zokulungisa ezigqithisileyo. Indlela ye-HELI ye-ODM idibanisa i-sprocket kunye ne-final drive interface kwi-assembly enye, ethembekileyo, eyenzelwe ukusebenza ngcono kwiindawo ezinzima zemigodi.

2. Isayensi yezinto ezibonakalayo kunye nendlela yoBunjineli be-ODM

Ifilosofi yethu yoyilo ijolise kwiindlela ezithile zokusilela ezibonwa kwimisebenzi yokwemba yeklasi ye-PC1250.

A. Isiqinisekiso seMetallurgical Foundation kunye neZinto:
Le ndibano yenziwe ngeentsimbi ezimbini ze-alloy ezahlukeneyo, ezisetyenziswa ngokukodwa:

• Umzimba weGiya/weSprocket: Sisebenzisa intsimbi ye-alloy yokuqinisa i-case efana ne-SAE 9310 (okanye i-DIN 18CrNiMo7-6). Le ntsimbi ye-nickel-chromium-molybdenum ikhethwe ngenxa yamandla ayo angaqhelekanga e-core (≥ 1100 MPa UTS) kunye nokuqina kwayo okugqwesileyo, okuvumela i-case enzulu, eqinileyo ngaphandle kokuphazamisa i-ductile, i-core enganyangekiyo yokudinwa efunekayo kumazinyo egiya kunye nee-sprocket lugs.
• IiGiya zePlaneti zangaphakathi kunye neeShafts: Kwezi zinto zixineneyo kakhulu, singasebenzisa iintsimbi ezicociweyo nge-vacuum-degas, ezikumgangatho we-carburizing (umz., i-SAE 8620) ukuqinisekisa ukuba isakhiwo esicocekileyo asinazo izinto ezinokubangela ukuqhekeka okanye ukuqhekeka.
• Zonke izinto ezingenayo ziqinisekisiwe ngeengxelo zovavanyo lwe-mill kwaye zixhomekeke ekuqinisekisweni kwe-spectrographic yangaphakathi.

B. Ukwenziwa Okuphambili kunye Noomatshini Abarhabaxa:
Izinto ezibalulekileyo zesakhiwo ziqala njengee-blanks ezenziwe ngobuchule obuchanekileyo. Le nkqubo:

• Ilungelelanisa iGrain Flow ecaleni kwendlela yamazinyo egiya kunye nee-sprocket lugs, inyusa ubomi bokudinwa ngezihlandlo ezi-2-3 xa kuthelekiswa nezinye iindlela ezenziwe ngomatshini ukusuka kwi-barstock.
• Isusa i-Internal Porosity kwaye iphucula uxinano, idala isakhiwo esifanayo esikwaziyo ukumelana nomthwalo ohamba ngesantya esiphezulu ngaphandle kokuqaliswa kokuqhekeka kwangaphakathi.

C. Ukwenziwa kweMishini ye-CNC echanekileyo kunye nokuveliswa kwezixhobo:
Izikhewu ezenziweyo neziqhelekileyo zenziwa ngomatshini we-CNC onama-axis amaninzi kunye nokusika izixhobo ezikhethekileyo.

• Ukuveliswa Kwamazinyo Egiya: Amazinyo okugqibela egiya aqhutywayo anqunyulwa kusetyenziswa i-CNC gear hobbling kulandele i-profile grinding ukuze kufezekiswe ukuchaneka kwe-AGMA Class 11 okanye ngaphezulu. Oku kuqinisekisa ukuhlanganiswa okupheleleyo kweegiya zangaphakathi zeplanethi, kunciphisa ingxolo, ukuveliswa kobushushu, kunye noxinzelelo lwendawo.
• Ukulungiswa kweProfayili yamazinyo eSprocket: Amazinyo esprocket angaphandle agutywa ngeprofayili ye-involute eguquliweyo kunye ne-root fillet elungiselelweyo. Uyilo lwethu lwe-ODM lungabandakanya i-geometry yamazinyo angafaniyo ukuze kulawulwe ngcono ukusasazwa komthwalo ongafaniyo ngexesha lokubandakanyeka kunye nokwahlukana, ukunciphisa uxinzelelo oluphezulu.
• I-Hub kunye ne-Interface Machining: I-mounting hub, ii-splines (okanye isangqa se-precision bolt), kunye neendawo ezibalekayo ze-seal zenziwe ngomatshini ogqityiweyo ukuya kumlinganiselo we-IT6 okanye ngaphezulu. Oku kuqinisekisa ukuqina okugqibeleleyo, kususa ukungalingani, kwaye kuqinisekisa ujongano olungenako ukuvuza kunye ne-drive housing yokugqibela.

D. Unyango lobushushu olunezigaba ezininzi:
Iindawo ezahlukeneyo zendibano zifumana iinkqubo zobushushu ezilungiselelwe wena.

1. I-Deep-Case Carburizing: Lonke i-gear/sprocket body iphantsi kwenkqubo ye-deep-case gas carburizing elawulwa yikhompyutha.
2. Ukucima igesi enoxinzelelo oluphezulu: Ukucima igesi okulawulwayo, okunoxinzelelo oluphezulu kunciphisa ukugqwetheka kobushushu ngelixa kufezekiswa imeko ye-martensitic efunekayo.
3. Unyango lweCryogenic (Olukhethwayo kwiNkonzo Enzima): Ukuze kubekho uzinzo olukhulu kunye nokumelana nokuguguleka, izinto zingaphathwa ngonyango olunzulu lwe-cryogenic ukuguqula i-austenite egciniweyo ibe yi-martensite.
4. Ukulinganisela okuBini: Inkqubo yokulinganisela okubini inciphisa uxinzelelo lwangaphakathi kwaye imisela iimpawu zokugqibela zoomatshini.
   • Iinkcukacha zeziphumo:
     • Ubunzulu beTsheyisi yamazinyo yeGiya/yeSprocket: 7.0 – 8.5 mm kwi-550 HV.
     • Ubunzima bomphezulu: 60 - 64 HRC.
     • Ukuqina kunye nokuqina kweCore: 38 - 42 HRC kunye namaxabiso aphezulu eCharpy V-notch.

E. Ukudibanisa, Ukutywina kunye nokuHlanganisa kokugqibela:
Iigiya zeplanethi zangaphakathi ezisemgangathweni, iibheringi, kunye nezitywini ezisebenzayo zihlanganiswe kwigumbi elicocekileyo elilawulwa yimozulu.

• Inkqubo Yokuvala: Sisebenzisa izitywina ze-labyrinth ezidityaniswe nezitywina ze-radial ezinemilebe emininzi ezisebenza nzima ezenziwe ngerabha ye-hydrogenated nitrile butadiene (HNBR) ukuze zikwazi ukumelana nobushushu, izinto ezirhabaxa, kunye nokuqhekeka kwe-lubricant.
• Ukuthambisa: Iindibano zizaliswe yioyile yegiya yokwenziwa esebenza kakhulu, enoxinzelelo olugqithisileyo (EP) echazwe kwizicelo zemigodi.

3. Ukuqinisekiswa koMgangatho weMigodi kunye nokuqinisekiswa kokusebenza

Yonke indibano iphantsi komgaqo-nkqubo wokuqinisekisa ogqibeleleyo:

1. I-Geometric & Dimensional Metrology: Uhlolo olupheleleyo lwe-3D CMM luqinisekisa i-geometry yamazinyo egiya, i-sprocket pitch, ubukhulu be-hub, kunye nokuqina kwendibano.
2. Uhlalutyo loBulukhuni kunye neMikroskopu: Ukuqinisekiswa kobunzulu betyala ngovavanyo lobunzima obuncinci kunye nokuhlolwa kwe-metallographic yeekhuphoni zesampulu.
3. Uvavanyo Olungonakalisiyo (NDT): I-100% MPI yazo zonke iindawo ezibalulekileyo kunye ne-100% UT yeendawo ezinoxinzelelo oluphezulu (iingcambu zamazinyo, ii-hub fillets).
4. Uvavanyo Lokusebenza Nokusebenza: Iyunithi nganye idlula kumjikelo wokusebenza ogcweleyo kwisixhobo sokuvavanya esilinganisa i-torque yokusebenza kunye nesantya. Olu vavanyo luqinisekisa:
   • Ukusebenza kakuhle nangokuzolileyo.
   • Ukungabikho kokuvuza kweoyile.
   • Umthwalo ochanekileyo webheri kunye nokunyuka kobushushu.

4. Inzuzo ye-HELI (CQCTRACK) ye-ODM kwiinqanawa zemigodi

• Uyilo Oludibeneyo Lokuthembeka: Siyila i-sprocket kunye ne-final drive interface njengenkqubo enye, sisusa ukungalingani okunokwenzeka kunye neendawo ezibuthathaka ezifumaneka kwiindawo ezizimeleyo.
• Umjikelo woBomi oQikelelweyo kwiindawo ezirhabaxa: Udibaniso lwe-metallurgy ye-premium, ukuqina kwe-deep-case, kunye ne-geometry yegiya/i-sprocket ephuculiweyo inika ubomi benkonzo obongezelelekileyo nobuqikelelweyo, nto leyo enciphisa ixesha lokungasebenzi elicwangcisiweyo.
• Ukutshintshwa ngokuthe ngqo ngeenkcukacha eziphuculweyo: Yenzelwe ukutshintshwa okungenamthungo ngelixa ibandakanya ukuphuculwa kwezinto kunye noyilo olusekelwe kwidatha yentsimi evela kwizicelo zemigodi.
• Ulawulo Olupheleleyo Lokuvelisa Oluthe Tye: Ukususela ekubumbeni ukuya ekuhlanganisweni kokugqibela, ulawulo lwethu lwangaphakathi luqinisekisa ukulandeleka, ukhuseleko lwekhonkco lokubonelela, kunye nomgangatho ohambelanayo, okumgangatho wemigodi.
