1. Isifinyezo Esiphezulu kanye Nokubuka Konke Kwengxenye

Lo mbhalo unikeza incazelo ephelele yobuchwepheshe be-Track Bottom Roller Assembly (eyaziwa nangokuthi i-Carrier Roller noma i-Lower Roller), ingxenye ebalulekile yomsebenzi we-Liebherr R974 kanye ne-HS870 series hydraulic excavators. Lo mhlangano wenzelwe ukusebenza ngaphansi kwemithwalo eqinile neguquguqukayo ezindaweni ezinzima njengezimayini, ukumba, kanye nokwakhiwa okunzima. Izinombolo zezingxenye ezibhekiselwe kuzo (kufaka phakathi10007992, 5209249, 5601511, 9109493) iphathelene nale nhlangano ethile kanye nezingxenye zayo ezincane noma izinguqulo zangaphambilini. Njengendlela ehlukile yekhwalithi ephezulu, abakhiqizi abanjengo-CQCTrack (isigaba esikhethekile se-HELI Group) bakhiqiza lezi zingxenye ukuze bahlangabezane noma badlule imininingwane yokusebenza kwemishini yokuqala, benikeza ikhambi eliqinile nelingabizi kakhulu lokulungisa inqola engaphansi kwemoto.

2. Umsebenzi Oyinhloko kanye Nendima Yokusebenza Ngaphakathi Kohlelo Lokukhasa

I-Bottom Roller Assembly iyisici esibalulekile sohlelo lwethrekhi lokukhasa, esenza imisebenzi emithathu ebalulekile:

• Ukusabalalisa Ukuthwala Imithwalo Nesisindo: Isekela ngqo ingxenye enkulu yesisindo esikhulu sokusebenza komshini (i-R974/HS870 ingadlula amathani angu-80-100), idlulisela umthwalo usuka kufreyimu enkulu ngefreyimu ye-track roller bese ungena ku-track chain.
• Isiqondiso Nokulungiswa Kwethrekhi: I-roller inezingcezu ezifakwe ngomshini oqondile kuzo zombili izinhlangothi eziqondisa unqenqema lwangaphakathi lwezixhumanisi zethrekhi ("izicathulo"). Lokhu kuvimbela ukuphuma kwesitimela eceleni futhi kuqinisekisa ukuthi ithrekhi isebenza kahle kuyo yonke indawo engaphansi kwenqola.
• Ukuphathwa Kokugoba Kwethrekhi: Kugcina inani elifanele lokucindezelwa kanye nokugoba engxenyeni engenhla yethrekhi, okubalulekile ekubandakanyekeni kahle kwe-sprocket, ukunciphisa ukudlidliza, kanye nokudluliswa kwamandla okulungile.

3. Imininingwane Yobuchwepheshe Eningiliziwe kanye Nomklamo Wobunjiniyela

3.1. Ukusebenza kanye ne-OEM Reference:

• Amamodeli Omshini Oyinhloko: i-Liebherr R974 Litronic, i-HS870, kanye nezinhlobo zawo.
• Izinombolo Zezingxenye ze-OEM:10007992, 5209249, 5601511, 5601611, 9109493, 2105021(Lezi zinombolo zingahambisana nokuhlanganiswa okuphelele, ama-roller ngamanye, noma ukucushwa kwekhithi. Umkhiqizi oqinisekisiwe njenge-CQCTrack ugcina isizindalwazi esibhekisela kuzo zonke izinhlobo ukuze athole ukunemba).

3.2. Umklamo Nokwakhiwa Kwemishini:

• Uhlobo: I-Roller Yesithwali Esinzima Esivalwe Futhi Esigcotshwe (S&L).
• Indlu/Ukwakha: Kwenziwe ngensimbi ye-alloy enekhabhoni ephezulu, enamandla amakhulu (isb., 40Mn2, 50Mn) ngokusebenzisa ukwakhiwa kwe-closed-die. Le nqubo iqinisekisa ukugeleza kokusanhlamvu okuqhubekayo, ukumelana nokushayisana okuphezulu, kanye namandla okukhathala angavamile uma kuqhathaniswa nezingxenye ezibunjiwe.
• Umgodi: Wenziwe ngomshini oqondile ngensimbi eqinile ye-chromium alloy (isb., 42CrMo), enikeza amandla aphezulu okudonswa kanye nokumelana nokuguguleka kuma-jenali bearings.
• Umklamo weFlange: Ukucushwa okunezinhlangothi ezimbili ukuze kunikezwe isiqondiso esihle kanye nokugcinwa kweketanga lomzila.

3.3. Isayensi Yezinto Ezibalulekile kanye Nensimbi:

• Izinga Lezinto: Izinsimbi ze-alloy ze-High-Carbon, i-Boron, noma i-Chromium-Manganese.
• Ukwelashwa Kokushisa: Izindawo ezigugile ezibucayi zilawulwa yi-Induction Hardening ukuze kufezwe ubulukhuni bomphezulu obungu-55-60 HRC (Rockwell C Scale), okuholela esikhaleni esijulile nesiqinile esinomgogodla oqinile, obamba ukushaqeka.
• Ukuqeda: Ukudubula ngesibhamu ukuze kuncishiswe ukucindezeleka nokulungiselela ubuso, kulandelwe uhlelo lokupenda olunamathelayo kakhulu nolungagqwali (ngokuvamile i-epoxy primer kanye ne-polyurethane topcoat).

3.4. Uhlelo Lokuthwala Nokuvala (Isisekelo Sokuqina):

• Uhlobo Lokuthwala: Ama-roller bearings anemigqa emibili, anzima futhi aqinile. Lawa akhethwa ngenxa yomthamo wawo ophezulu womthwalo we-radial kanye nekhono lokuphatha imithwalo yokudonsa ye-axial ephakathi nendawo.
• Uhlelo Lokuvala: Ukuhlanganiswa kwesivalo esinezithiyo eziningi, isitayela se-labyrinth. Lokhu kuvame ukuqukatha: Ukugcoba: Kugcwaliswa kusengaphambili ngegrisi ye-lithium complex enokushisa okuphezulu, enomfutho owedlulele (EP) eyenzelwe ukugcina ukuthamba kanye nokugcoba ngaphansi kwazo zonke izimo zokusebenza.
  • Isivalo Esiyinhloko: Isivalo sezindebe esinobubanzi be-nitrile (NBR) noma i-polyurethane (PU).
  • Isiciko Sesibili: Isisiciko sobuso esintantayo noma udebe lothuli olwengeziwe.
  • Indlela Yokugedla: Indlela eyinkimbinkimbi, eyenziwe ngomshini engafaki ukungcola okuhudulayo (i-silica, udaka, uthuli) ekamelweni lokuthwala.

4. Inqubo Yokukhiqiza Nokuqinisekiswa Kwekhwalithi e-CQCTrack (HELI)

Njengomkhiqizi okhethekile, i-CQCTrack isebenzisa inqubo yokukhiqiza eqinile:

1. Ukwakha Nokwakha: Ama-billet aluhlaza ayashiswa futhi akhiwe ngaphansi kwengcindezi ephezulu ukuze kudale i-roller engenalutho, okuqinisekisa ubuqotho bensimbi obufanele.
2. Umshini: Izikhungo zokujika ze-CNC (Computer Numerical Control) kanye nezokubhoboza zisetshenziselwa ukushibilikisa ububanzi bangaphandle be-roller, ama-flange, kanye ne-internal bore kuya ekubekezeleleni okuqinile (ngokuvamile i-IT7-IT8).
3. Ukwelashwa Kokushisa: Izingxenye zidlula enkambisweni yokucima nokushisa elawulwayo, kulandelwe ukuqina kokufakwa kwendawo ebusweni obungaphandle bokugijima kanye nama-flange.
4. Ukuhlanganiswa Nokuvalwa: Ama-bearings kanye nezivalo kucindezelwa endaweni endaweni ehlanzekile yegumbi. Iyunithi ibe isigcwaliswa ngobuningi obuqondile bamafutha.
5. Ukulawulwa Kwekhwalithi (QC):
   • Ukuhlolwa Kobukhulu: Ukuqinisekiswa kwe-CMM (Umshini Wokulinganisa Ohlanganisayo) kwazo zonke izilinganiso ezibalulekile.
   • Ukuhlolwa Kokuqina: Ukuhlolwa kweRockwell neBrinell ezindaweni ezithile.
   • Ukuhlolwa Kokusebenza: Ukuhlolwa kwe-torque ejikelezayo kanye nokuhlolwa kokuphelelwa yisikhathi ukuqinisekisa ukusebenza kahle kanye nokusebenza kahle kwesivalo.
   • Isitifiketi Sezinto Ezisetshenziswayo: Izitifiketi Zokugaya izinto zokusetshenziswa kanye nokuhlaziywa kokwakheka kwamakhemikhali.

5. Umongo Wokuthola Nokuhlinzeka Ngempahla

• Ukuhlonza Umkhiqizi: I-CQCTrack isebenza njengefektri ezinikele yezingxenye zezimoto ezingaphansi kwenqola ngaphakathi kwe-ecosystem ye-HELI Group. I-HELI iyinkampani yezimboni eyaziwayo emhlabeni wonke, enikeza ingqalasizinda edingekayo, ikhono locwaningo nokuthuthukiswa, kanye nezinhlelo zokuphatha ikhwalithi (isb., i-ISO 9001, i-ISO 14001) yokukhiqiza izingxenye zemishini zezinga lomhlaba.
• Isiphakamiso Senani: Ukuthola le ngxenye efektri efana ne-CQCTrack kunikeza okunye okusekelwe enanini kunezingxenye zangempela ze-OEM. Kuhlanganisa amanani aqondile avela efektri nobunjiniyela obuklanyelwe ukumelana nezimo ezidingayo i-Liebherr R974/HS870 eklanyelwe zona.

6. Isifinyezo Sezinzuzo Eziyinhloko Zobuchwepheshe

• Umthamo Ophakeme Womthwalo: Wenzelwe izisindo ezinkulu kanye nemithwalo yokushaqeka yemishini yokumba izimayini.
• Ukumelana Nokuguguleka Okuthuthukisiwe: Ukuqina kokufakwa okujulile kwandisa kakhulu impilo yesevisi ezindaweni eziguguleka kakhulu.
• Ukukhishwa Kokungcola Okuthuthukisiwe: Uhlelo lokuvala olunezigaba eziningi luvikela i-bearing, uhlelo olubaluleke kakhulu lwengxenye.
• Ubunjiniyela Bokucacisa: Umshini wokugaya we-CNC uqinisekisa ukuhambisana okuphelele futhi uhambisana nohlaka lwe-track roller olukhona kanye nochungechunge lwe-track.
• Ukwakhiwa Okuqinile: Umzimba ohlanganisiwe unikeza ubuqotho besakhiwo obungenakuqhathaniswa kanye nokumelana nokushayisana.

Ekuphetheni, i-Track Bottom Roller Assembly echazwe kwi-Liebherr R974/HS870 imelela isiqongo sobunjiniyela bezimoto ezithwala abantu abasebenza kanzima. Abakhiqizi abanjengo-CQCTrack, besebenzisa ikhono lezimboni le-HELI Group, baphinda futhi banikeze lezi zingxenye ngokuzibophezela okuqinile ekhwalithini yezinto ezibonakalayo, ukunemba kobukhulu, kanye nokuqina kokusebenza okudingekayo ekusebenzeni kwezimboni amahora angama-24 ngosuku, izinsuku eziyi-7 ngesonto.
