1. Isishwankathelo soLawulo kunye noBuchule beCandelo

Olu xwebhu lubonelela ngengcaciso epheleleyo yobuchwephesha beTrack Bottom Roller Assembly (ekwaziwa ngokuba yiCarrier Roller okanye iLower Roller), into ebalulekileyo kumsebenzi we-Liebherr R974 kunye ne-HS870 series hydraulic excavators. Le ndibano yenzelwe ukusebenza phantsi kwemithwalo enzima neguquguqukayo kwiindawo ezinzima ezifana nokwemba, ukumba, kunye nokwakhiwa okunzima. Amanani eenxalenye akhankanyiweyo (kuquka10007992, 5209249, 5601511, 9109493) malunga nale ndibano ithile kunye nezinto zayo ezincinci okanye iinguqulelo zangaphambili. Njengendlela eyahlukileyo yomgangatho ophezulu emva kwemarike, abavelisi abanjengoCQCTrack (icandelo elikhethekileyo leQela le-HELI) bavelisa ezi zinto ukuze zihlangabezane okanye zidlule iinkcukacha zokusebenza kwezixhobo zokuqala, bebonelela ngesisombululo esomeleleyo nesingabizi kakhulu sokugcinwa kwesithuthi esingaphantsi kwesithuthi.

2. Umsebenzi oPhambili kunye neNdima yokuSebenza ngaphakathi kwiNkqubo yokuKhasa

I-Bottom Roller Assembly yinxalenye ebalulekileyo yenkqubo yendlela yokukhasa, eyenza imisebenzi emithathu ebalulekileyo:

• Ukusasazwa koMthwalo kunye noBunzima: Ixhasa ngokuthe ngqo inxalenye enkulu yobunzima obukhulu bokusebenza komatshini (i-R974/HS870 ingadlula iitoni ezingama-80-100), idlulisela umthwalo ukusuka kwifreyimu ephambili ngesakhelo serola yethrekhi ukuya kwitsheyini yethrekhi.
• Isikhokelo kunye noLungelelaniso lweNdlela: Irola ineeflanges ezilungisiweyo ngokuchanekileyo kumacala omabini ezikhokela umda wangaphakathi weekhonkco zethrekhi ("izihlangu"). Oku kuthintela ukuphuma kwereyile ecaleni kwaye kuqinisekisa ukuba indlela ihamba kakuhle kuyo yonke indawo engaphantsi kwesithuthi.
• Ulawulo lwe-Track Sag: Igcina ubungakanani obuchanekileyo be-pre-tension kunye ne-sag kwicandelo eliphezulu le-track chain, nto leyo ibalulekileyo ekusebenzeni kakuhle kwe-sprocket, ukunciphisa ukungcangcazela, kunye nokudluliselwa kwamandla ombane ngokugqibeleleyo.

3. Iinkcukacha zoBugcisa ezineenkcukacha kunye noYilo loBunjineli

• Indlu/Ukufakelwa: Yenziwe ngentsimbi ye-alloy enekhabhoni ephezulu, enamandla aphezulu (umz., 40Mn2, 50Mn) nge-closed-die forging. Le nkqubo iqinisekisa ukuhamba kweenkozo okuqhubekayo, ukumelana okuphezulu kwempembelelo, kunye namandla okudinwa angaqhelekanga xa kuthelekiswa nezinto ezibunjiweyo.
• Ishaft: Yenziwe ngokuchanekileyo ngentsimbi eqinileyo ye-chromium alloy (umz., 42CrMo), inika amandla aphezulu okutsalwa kunye nokumelana nokuguguleka kwiibheringi zejenali.
• Uyilo lweFlange: Ulwakhiwo olunemiphetho emibini ukuze kubonelelwe ngesikhokelo esihle kunye nokugcinwa kwekhonkco lendlela.

3.3. Isayensi yezinto eziphathekayo kunye nesinyithi:

• Udidi lwezinto: Iintsimbi ze-alloy ze-High-Carbon, i-Boron, okanye i-Chromium-Manganese.
• Unyango Lobushushu: Iindawo ezigugileyo ezibalulekileyo zilawulwa yi-Induction Hardening ukuze kufikelelwe kubunzima bomphezulu obuyi-55-60 HRC (Rockwell C Scale), nto leyo ebangela ukuba ityesi enzulu nehlala ixesha elide enomongo oqinileyo, obamba ukuthuthumela.
• Isiphelo: Ukudutyulwa kweembumbulu ukuze kuncitshiswe uxinzelelo kunye nokulungiswa komphezulu, kulandele inkqubo yepeyinti enamathelayo kakhulu, engangenisi umhlwa (ngesiqhelo i-epoxy primer kunye ne-polyurethane topcoat).

3.4. Inkqubo yoBearing kunye nokutywina (Isiseko sokuqina):

• Uhlobo lweeBheri: Iibheringi zerola ezixineneyo ezimiqolo emibini, ezinzima. Ezi zikhethwa ngenxa yomthamo wazo ophezulu womthwalo weradial kunye nokukwazi ukulawula imithwalo yokutyhala ye-axial ephakathi.
• Inkqubo yokutywina: Indibano yesitywina esinemiqobo emininzi, esifana ne-labyrinth. Oku kudla ngokuquka oku: Ukuthambisa: Kuzaliswa kwangaphambili ngegrisi ye-lithium complex enobushushu obuphezulu, enoxinzelelo olugqithisileyo (EP) eyenzelwe ukugcina i-viscosity kunye nokuthambisa phantsi kwazo zonke iimeko zokusebenza.
  • Itywina eliPhambili: Itywina lemilebe ye-nitrile (NBR) okanye i-polyurethane (PU).
  • Itywina lesibini: Itywina lobuso elidadayo okanye umlebe wothuli owongezelelweyo.
  • Indlela yeLabyrinth: Indlela enzima, eyenziwe ngomatshini engabandakanyi izinto ezingcolisayo (i-silica, udaka, uthuli) kwigumbi lokuthwala.

4. Inkqubo yoMveliso kunye noQinisekiso loMgangatho eCQCTrack (HELI)

Njengomvelisi okhethekileyo, i-CQCTrack isebenzisa inkqubo yemveliso engqongqo:

1. Ukwakha nokwakha: Iibhilethi eziluhlaza ziyafudunyezwa kwaye zenziwe phantsi koxinzelelo oluphezulu ukuze i-roller ingabi nanto, ukuqinisekisa ukuthembeka kwesinyithi okufanelekileyo.
2. Umatshini: Iziko lokujika kunye nelokubhitya le-CNC (Computer Numerical Control) zisetyenziselwa ukutshixa ububanzi bangaphandle berola, iiflanges, kunye nebhore yangaphakathi ukuya kwii-tight tolerances (ngesiqhelo i-IT7-IT8).
3. Unyango lobushushu: Ezi zinto zilawulwa yinkqubo yokucima nokulungisa, kulandele ukuqina kwe-induction kwindawo engaphandle kunye neeflanges.
4. Ukuhlanganiswa kunye nokutywinwa: Iibheringi kunye nezitywino zicinezelwa kwindawo ecocekileyo kwigumbi. Emva koko iyunithi izaliswa ngomthamo ochanekileyo wegrisi.
5. Ulawulo loMgangatho (QC):
   • Uhlolo lweMilinganiselo: Ukuqinisekiswa kweCMM (uMatshini wokulinganisa oQokelelweyo) kwazo zonke izilinganiso ezibalulekileyo.
   • Uvavanyo loBulukhuni: Uvavanyo lweRockwell noBrinell kwiindawo ezithile.
   • Uvavanyo Lokusebenza: Uvavanyo lwe-torque ejikelezayo kunye novavanyo lokuphelelwa ngamandla ukuqinisekisa ukusebenza kakuhle kunye nokusebenza ngokuchanekileyo kwesitywina.
   • Isiqinisekiso sezinto: Iziqinisekiso zokugaya izinto eziluhlaza kunye nohlalutyo lokwakheka kweekhemikhali.

5. Umxholo we-Sourcing kunye ne-Supply Chain

• Ukuchongwa koMvelisi: I-CQCTrack isebenza njengomzi-mveliso ozinikeleyo wezinto ezingaphantsi kwesithuthi ngaphakathi kwenkqubo yendalo yeQela le-HELI. I-HELI yinkampani yemizi-mveliso eyaziwayo kwihlabathi liphela, ebonelela ngeziseko eziyimfuneko, amandla ophando nophuhliso, kunye neenkqubo zolawulo lomgangatho (umz., i-ISO 9001, i-ISO 14001) zokwenza izixhobo zoomatshini ezikumgangatho wehlabathi.
• Ingcebiso yeXabiso: Ukufumana eli candelo kumzi-mveliso ofana ne-CQCTrack kunika enye indlela esekwe kwiXabiso kwiindawo zokwenyani ze-OEM. Idibanisa amaxabiso ngqo avela kumzi-mveliso kunye nobunjineli obulungiselelwe ukumelana neemeko ezinzima ezenzelwe zona i-Liebherr R974/HS870.

6. Isishwankathelo seeNzuzo zobuChwepheshe eziphambili

• Umthamo woMthwalo oPhezulu: Yenzelwe ubunzima obukhulu kunye nemithwalo yoxinzelelo yemigodi yokumba.
• Ukumelana Nokukrala Okuphuculweyo: Ukuqina kokufakelwa okunzulu kwandisa ubomi benkonzo kwiindawo ezinxitywa kakhulu.
• Ukususwa kongcoliseko oluPhambili: Inkqubo yokutywina enamanqanaba amaninzi ikhusela ibhereyitha, eyona nkqubo ibaluleke kakhulu kwicandelo.
• Ubunjineli Bokuchaneka: Umatshini wokugaya i-CNC uqinisekisa ukuhambelana ngokugqibeleleyo kwaye uhambelana nesakhelo se-track roller kunye ne-track chain ekhoyo.
• Ulwakhiwo Oluqinileyo: Umzimba oqingqiweyo unika ukuqina kolwakhiwo olungenakuthelekiswa nanto kunye nokumelana nempembelelo.

Ukuqukumbela, iTrack Bottom Roller Assembly echazwe kwiLiebherr R974/HS870 imele incopho yobunjineli bezithuthi eziphantsi kwesithuthi esinzima. Abavelisi abanjengoCQCTrack, besebenzisa ubuchule bemizi-mveliso beHELI Group, bayaphinda kwaye bahambise ezi zinto ngokuzibophelela ngokuqinileyo kumgangatho wezinto eziphathekayo, ukuchaneka kobukhulu, kunye nokuqina kokusebenza okufunekayo ekusebenzeni kwemizi-mveliso iiyure ezingama-24 ngosuku, iintsuku ezisixhenxe ngeveki.
