Tsamba la Deta Yaukadaulo: Msonkhano Wozungulira Wokhala ndi Ntchito Yaikulu wa Zitsulo Zofukula Madzi za Liebherr R974/HS870

Chizindikiro cha Zikalata: LIEBHERR-R974-HS870-Bottom-Roller-Assy-CQCTrack
Gulu: Gawo la Pansi pa Galimoto | Dongosolo la Crawler | Gawo Losinthira

1. Chidule cha Akuluakulu & Chidule cha Zigawo

Chikalatachi chikupereka tsatanetsatane waukadaulo wa Track Bottom Roller Assembly (yomwe imadziwikanso kuti Carrier Roller kapena Lower Roller), gawo lofunika kwambiri pa ntchito ya Liebherr R974 ndi HS870 series hydraulic excavators. Gululi lapangidwa kuti ligwire ntchito pansi pa katundu wosasunthika komanso wosinthasintha m'malo ovuta monga migodi, miyala, ndi zomangamanga zolemera. Manambala a zigawo omwe atchulidwa (kuphatikiza10007992, 5209249, 5601511, 9109493() zokhudzana ndi msonkhano wapaderawu ndi zigawo zake zazing'ono kapena mitundu yakale. Monga njira ina yabwino kwambiri yogulitsira pambuyo pake, opanga monga CQCTrack (gawo lapadera la HELI Group) amapanga zigawozi kuti zikwaniritse kapena kupitirira zomwe zidazo zimagwira ntchito, zomwe zimapereka yankho lolimba komanso lotsika mtengo pakukonza magalimoto pansi pa galimoto.

2. Ntchito Yoyamba & Udindo Wogwira Ntchito Mu Dongosolo Lokwawa

Cholumikizira cha Bottom Roller ndi gawo lofunika kwambiri la njira yoyendera, ndipo chimagwira ntchito zitatu zofunika:

• Kugawa Kulemera ndi Kulemera: Imathandizira mwachindunji gawo lalikulu la kulemera kwakukulu kwa makina (R974/HS870 ikhoza kupitirira matani 80-100), kusamutsa katundu kuchokera ku chimango chachikulu kudzera mu chimango cha track roller ndikuyika mu unyolo wa track.
• Malangizo ndi Kulinganiza Njira: Chozungulirachi chili ndi ma flange opangidwa bwino mbali zonse ziwiri omwe amatsogolera m'mphepete mwa maulalo a unyolo wa njira ("nsapato"). Izi zimaletsa kusokonekera kwa njanji kumbali ndikuwonetsetsa kuti njirayo ikuyenda bwino m'galimoto yonse yapansi panthaka.
• Kusamalira Kutsika kwa Track: Kumasunga kuchuluka koyenera kwa kupsinjika ndi kutsika kwa pre-tension m'gawo lapamwamba la unyolo wa track, zomwe ndizofunikira kwambiri kuti sprocket igwire bwino ntchito, kuchepetsa kugwedezeka, komanso kutumiza mphamvu moyenera.

3. Mafotokozedwe Atsatanetsatane Aukadaulo & Kapangidwe ka Uinjiniya

3.1. Kugwiritsa Ntchito & Chizindikiro cha OEM:

• Mitundu Yoyamba ya Makina: Liebherr R974 Litronic, HS870, ndi mitundu yawo.
• Manambala a Zigawo za OEM:10007992, 5209249, 5601511, 5601611, 9109493, 2105021(Ziwerengerozi zitha kufanana ndi ma assemblies athunthu, ma roller osiyanasiyana, kapena ma configurations a zida. Wopanga wovomerezeka monga CQCTrack amasunga database yolumikizirana kuti atsimikizire kulondola).

3.2. Kapangidwe ndi Kapangidwe ka Makina:

• Mtundu: Chotsekera Chonyamula Zinthu Zolemera Chotsekedwa ndi Chopaka Mafuta (S&L).
• Nyumba/Kupanga: Yopangidwa ndi chitsulo cha alloy chokhala ndi mpweya wambiri, cholimba kwambiri (monga 40Mn2, 50Mn) pogwiritsa ntchito closed-die forging. Njirayi imatsimikizira kuti tirigu umayenda bwino nthawi zonse, kukana kukhudza kwambiri, komanso mphamvu yotopa kwambiri poyerekeza ndi zida zopangidwa ndi chitsulocho.
• Shaft: Yopangidwa mwaluso kwambiri kuchokera ku chitsulo cholimba cha chromium alloy (monga, 42CrMo), chomwe chimapereka mphamvu yayikulu yolimba komanso kukana kuwonongeka pa mabearing a journal.
• Kapangidwe ka Flange: Kapangidwe ka flange kawiri kuti kapereke chitsogozo chabwino komanso choletsa unyolo wa njanji.

3.3. Sayansi ya Zinthu ndi Zachitsulo:

• Gulu la Zinthu: Zitsulo za Alloy za High-Carbon, Boron, kapena Chromium-Manganese.
• Kutentha: Malo owonongeka kwambiri amawongoleredwa kuti apeze kuuma kwa pamwamba pa 55-60 HRC (Rockwell C Scale), zomwe zimapangitsa kuti chikwamacho chikhale cholimba komanso cholimba chokhala ndi pakati wolimba komanso wonyamula mantha.
• Kumaliza: Kuphulitsa ndi mfuti kuti muchepetse kupsinjika ndi kukonzekera pamwamba, kutsatiridwa ndi utoto wolimba kwambiri komanso wosagwira dzimbiri (nthawi zambiri umakhala ndi epoxy primer ndi polyurethane topcoat).

3.4. Dongosolo Lopangira ndi Kutseka (Chinthu Chachikulu Cholimba):

• Mtundu wa Bearing: Ma bearing ozungulira okhala ndi mizere iwiri, olemera komanso opindika. Izi zimasankhidwa chifukwa cha mphamvu yawo yayikulu yonyamula ma radial komanso kuthekera koyendetsa katundu wocheperako wa axial.
• Njira Yotsekera: Kusonkhanitsira zisindikizo zamitundu yosiyanasiyana, zamtundu wa labyrinth. Izi nthawi zambiri zimakhala ndi: Kudzola: Kudzazitsidwa kale ndi mafuta a lithiamu complex okhala ndi kutentha kwambiri, opanikizika kwambiri (EP) omwe adapangidwa kuti asunge kukhuthala ndi kukhuthala pansi pa mikhalidwe yonse yogwirira ntchito.
  • Chisindikizo Choyamba: Chisindikizo cha milomo cha nitrile (NBR) kapena polyurethane (PU).
  • Chisindikizo Chachiwiri: Chisindikizo cha nkhope choyandama kapena mlomo wowonjezera wa fumbi.
  • Njira Yopingasa: Njira yovuta, yopangidwa ndi makina yomwe imachotsa zinthu zodetsa (silika, matope, fumbi) m'chipinda chonyamulira.

4. Njira Zopangira ndi Kutsimikizira Ubwino ku CQCTrack (HELI)

Monga wopanga wapadera, CQCTrack imagwiritsa ntchito njira yolimba yopangira:

1. Kupanga ndi Kupanga: Ma billet osaphika amatenthedwa ndi kupangidwa pansi pa kupanikizika kwakukulu kuti apange chopukutira chopanda kanthu, kuonetsetsa kuti chitsulo chili bwino kwambiri.
2. Machining: Malo ozungulira ndi oboola a CNC (Computer Numerical Control) amagwiritsidwa ntchito popangira makina akunja kwa chozungulira, ma flange, ndi chibowo chamkati mpaka ku tolerances zolimba (nthawi zambiri IT7-IT8).
3. Kutentha: Zigawozo zimayendetsedwa ndi njira yozimitsira ndi kutenthetsa, kenako zimayikidwa pamalo okhazikika pamwamba pa payipi ndi ma flange.
4. Kumanga ndi Kutseka: Maberiya ndi zisindikizo zimakanikizidwa pamalo ake m'chipinda choyera. Kenako chipangizocho chimadzazidwa ndi mafuta okwanira.
5. Kulamulira Ubwino (QC):
   • Kuyang'anira Miyeso: Kutsimikizira kwa CMM (Coordinate Measuring Machine) kwa miyeso yonse yofunika.
   • Kuyesa Kulimba: Mayeso a Rockwell ndi Brinell pamalo enaake.
   • Kuyesa Magwiridwe Antchito: Kuyesa kwa torque yozungulira ndi kuthamanga kuti zitsimikizire kuti ntchito yake ndi yolondola komanso kuti chisindikizocho chikugwira ntchito bwino.
   • Chitsimikizo cha Zinthu: Zitsimikizo za mphero za zipangizo zopangira ndi kusanthula kapangidwe ka mankhwala.

5. Nkhani Yokhudza Kupeza Zinthu ndi Kupereka Zinthu

• Kuzindikiritsa Wopanga: CQCTrack imagwira ntchito ngati fakitale yodzipereka yopangira zida zoyendera pansi pa galimoto mkati mwa chilengedwe cha HELI Group. HELI ndi kampani yodziwika padziko lonse lapansi yamakampani, yomwe imapereka zomangamanga zofunikira, luso la kafukufuku ndi chitukuko, komanso njira zoyendetsera bwino (monga ISO 9001, ISO 14001) popanga zida zamakina zapamwamba kwambiri padziko lonse lapansi.
• Kufotokozera Mtengo: Kupeza chinthu ichi kuchokera ku fakitale ngati CQCTrack kumapereka njira ina yochokera ku Mtengo m'malo mwa zida zenizeni za OEM. Zimaphatikiza mitengo yochokera ku fakitale mwachindunji ndi uinjiniya womwe umapangidwa kuti upirire mikhalidwe yovuta yomwe Liebherr R974/HS870 idapangidwira.

6. Chidule cha Ubwino Waukulu wa Ukadaulo

• Kulemera Kwambiri: Yopangidwa kuti igwire ntchito yolemera kwambiri komanso yodzaza ndi zida zogwirira ntchito m'migodi.
• Kulimbana ndi Kutupa Kwambiri: Kulimba kwa induction yozama kumawonjezera nthawi yogwira ntchito m'malo omwe amagwiritsidwa ntchito kwambiri.
• Kuchotsa Kuipitsidwa Kwambiri: Dongosolo lotsekera la magawo ambiri limateteza bearing, yomwe ndi gawo lofunika kwambiri la gawoli.
• Uinjiniya Wabwino Kwambiri: Makina opangira CNC amatsimikizira kuti akugwirizana bwino ndi chimango cha track roller ndi unyolo wa track womwe ulipo.
• Kapangidwe Kolimba: Thupi lopangidwa limapereka umphumphu wosayerekezeka komanso kukana kugwedezeka.

Pomaliza, Track Bottom Roller Assembly yomwe yatchulidwa pa Liebherr R974/HS870 ikuyimira chipambano chachikulu cha uinjiniya wolemera wa pansi pa galimoto. Opanga monga CQCTrack, pogwiritsa ntchito luso la mafakitale la HELI Group, amabwerezabwereza ndikupereka zinthuzi modzipereka kwambiri ku khalidwe la zinthuzo, kulondola kwa mawonekedwe ake, komanso kulimba kwa magwiridwe antchito komwe kumafunikira kuti ntchito zamafakitale ziyende bwino maola 24 pa tsiku, masiku 7 pa sabata.
