SANY SSY009115264 SY750 Track Bottom Roller Assembly-Wopanga zida zoyendera pansi pa galimoto zolemera-HELI(cqctrack)

1. Kuzindikiritsa Zigawo ndi Tanthauzo la Ntchito

Cholumikizira cha Track Bottom Roller (Nambala ya Chigawo cha OEM:SSY009115264) ndi gawo lalikulu lonyamula katundu mkati mwa kapangidwe ka msewu wapansi wa excavator ya SANY SY750 yolemera kwambiri. Yopangidwa ndi HELI (CQCTRACK) ngati chosinthira chokonzedwa bwino, gawoli—lomwe limatchedwanso lower roller kapena track roller—limayikidwa mwachindunji ku chimango cha msewu ndipo limapanga kulumikizana kwakukulu pakati pa kulemera kwakukulu kwa makina ndi unyolo wa njanji. Ntchito yake yayikulu ndikuchirikiza kulemera konse kwa makinawo pamene akuthandizira kuyenda bwino kwa msewu kudutsa malo ovuta kwambiri.

2. Udindo Wofunika Kwambiri pa Ntchito ndi Zofunikira pa Kugwira Ntchito

Pa makina a sikelo ya SY750 (matani pafupifupi 75-85), chozungulira chapansi chimagwira ntchito pansi pamavuto aakulu, zomwe zimafuna uinjiniya wapadera:

• Chonyamulira Cholemera Chachikulu: Chimathandizira mwachindunji kulemera kosasinthasintha komanso kosinthasintha kwa chofukula, ndikutumiza mphamvu zoyankhira pansi kupita mmwamba kudzera mu chimango cha njanji. Chiyenera kupirira katundu waukulu wa radial panthawi yokumba, kunyamula, ndi kuyenda.
• Chitsogozo ndi Kukhazikika kwa Unyolo wa Njira: Chimapereka njira yopitilira komanso yolimba kuti maulumikizidwe a unyolo wa njira ndi ma bushings aziyendamo, kusunga bata la mbali ndikuletsa kusokonekera kwa njanji pansi pa kupsinjika kwakukulu kwa mbali.
• Kuchepetsa Kugwedezeka ndi Kugwedezeka: Kumagwira ntchito ngati mzere woyamba wodzitetezera pochotsa katundu wokhudzana ndi ngozi kuchokera ku nthaka yosalinganika, mipando ya miyala, ndi zopinga zina, kuteteza pansi pa galimoto yonse ndi kapangidwe kake kapamwamba ku kuwonongeka koyambitsidwa ndi mantha komanso kutopa kwa woyendetsa.
• Kusamalira Zodetsa: Kapangidwe kake ndi njira yake yotsekera iyenera kuchotsa mwamphamvu tinthu tomwe timayabwa (silika, fumbi lachitsulo) ndi chinyezi, zomwe ndi zinthu zazikulu zomwe zimapangitsa kuti mabearing awonongeke msanga komanso kuti mabearing alephere kugwira ntchito m'migodi.

3. Zambiri Zokhudza Uinjiniya ndi Zinthu Zake

Njira yopangira HELI ya chipangizochi imagwiritsa ntchito zinthu zofunika kwambiri zomwe zingagwiritsidwe ntchito pochimba migodi:

• Thupi Lozungulira & Ma Flanges:
  • Zipangizo: Zopangidwa ndi chitsulo chopangidwa ndi boron (monga 50B kapena zina zofanana). Izi zimapangitsa kuti zikhale zolimba, zolimba, komanso zosagwirizana ndi kuwonongeka.
  • Kutentha: Malo othamanga akunja ndi ma flange amalimba kwambiri pogwiritsa ntchito carburizing, kenako amatenthedwa. Izi zimapangitsa kuti malo ouma kwambiri (HRC 58-63) akhale ndi kuya kokwanira kupirira zaka zambiri zokhuzana ndi kugwedezeka, mothandizidwa ndi pakati pamphamvu komanso yogwira mtima.
  • Kukonza Machining: Kukonza CNC kumaonetsetsa kuti malo olumikizirana ndi makinawo ndi olondola, mawonekedwe a flange, komanso kukhazikika kwa pamwamba pa flange. Kutalika ndi makulidwe a flange zimapangidwa kuti zikhale ndi unyolo wa track womwe umagwiritsidwa ntchito pa SY750.
• Dongosolo Loyendetsera Shaft & Bearing:
  • Shaft: Yopangidwa ndi chitsulo chozimitsidwa komanso chofewa (42CrMo4). Ma bearing journals amaphwanyidwa bwino, ndipo nthawi zambiri amachiritsidwa ndi induction hardening kapena plasma nitriding kuti asawonongeke ndi dzimbiri komanso kuwonongeka.
  • Kapangidwe ka Bearing: Imagwiritsa ntchito ma roller bearing akuluakulu kwambiri, okhala ndi mizere iwiri kapena ma roller bearing ozungulira okhala ndi ma dynamic load ratings owonjezereka. Izi zimayikidwa kale ndipo zimakonzedwa kuti zigwire mphamvu zambiri za excavator ya migodi.
  • Kuyika: Shaft nthawi zambiri imakhala yolumikizidwa ndi flange kapena bolt, yokhazikika bwino mkati mwa thupi la roller kuti isazungulire ndikuwonetsetsa kuti torque yonse yadutsa kudzera mu ma bearing.
• Ukadaulo Wosindikiza Wapamwamba:
  • Chisindikizo cha katiriji chokhala ndi zigawo zambiri ndi chokhazikika. Dongosololi nthawi zambiri limaphatikiza:
    1. Chisindikizo chachikulu cha milomo chopangidwa ndi hydrogenated nitrile (HNBR) kuti chiteteze kutentha kwambiri komanso mankhwala.
    2. Chisindikizo chachiwiri choyandama kapena labyrinth yachitsulo kuchokera kuchitsulo kupita kuchitsulo.
    3. Chopondera chakunja ndi mlomo wa fumbi kuti zichotse zinyalala zazikulu.
  • M'bowo lotsekedwa muli mafuta a lithiamu complex okhala ndi kukhuthala kwakukulu, okhazikika komanso osasunthika okhala ndi zowonjezera zodzoladzola zolimba (monga molybdenum disulfide) zotetezera mafuta odzola m'malire.
• Kapangidwe ka Mafuta Odzola ndi Kusamalira: Kali ndi mafuta olemera ogwiritsira ntchito pokonzanso nthawi. Mapangidwe ena amatha kukhala ndi valavu yochepetsera mafuta kuti apewe kuwonongeka kwa chisindikizo chifukwa cha kupanikizika kwambiri.

4. Mbiri Yopangira: Mphamvu za HELI (CQCTRACK)

Kupanga kwa HELI kwa gawoli kumagwiritsa ntchito luso lake pa zida zazikulu kwambiri zoyendera pansi pa galimoto:

• Kuphatikizika kwa Njira Yoyima: Kulamulira kwathunthu kuyambira kusankha zitsulo zachitsulo ndi kupanga zida zotsekedwa, mpaka kukonza, kukonza kutentha, ndi kusonkhanitsa.
• Kupangira ndi Kutentha: Kumagwiritsa ntchito makina osindikizira olemera kwambiri kuti akwaniritse kuyenda bwino kwa tirigu. Zitofu zotenthetsera zomwe zimayendetsedwa ndi kompyuta komanso mizere yotenthetsera zimatsimikizira kuuma kofanana komanso kozama.
• Ndondomeko Yoyesera ndi Ubwino:
  • Chitsimikizo cha Zinthu: Kutsatira kwathunthu ndi malipoti oyesera mankhwala ndi makina.
  • Kuyesa Kosawononga (NDT): Kupaka utoto (DPI) kapena kuyang'anira tinthu tating'onoting'ono ta magnetic (MPI) pa malo onse ofunikira pambuyo popangira ndi kukonza.
  • Kutsimikizira kwa Miyeso: Kuyang'ana kwa Makina Oyezera Ogwirizana (CMM) kwa geometry yomaliza.
  • Kuyesa Magwiridwe Antchito: Kuyesa mphamvu yozungulira ndi kuyesa kuthamanga kwa chisindikizo potengera zitsanzo kuti zitsimikizire umphumphu wa msonkhano.

5. Chidziwitso cha Kugwiritsa Ntchito, Kugwirizana ndi Utumiki

• Kugwiritsa Ntchito Kwambiri kwa Chitsanzo: SANY SY750 Crawler Excavator (Kukonza Migodi).
• Kuphatikiza Dongosolo: Mayunitsi angapo amayikidwa pansi pa chimango cha njanji, molunjika mothandizira chingwe chapansi cha unyolo wa njanji.
• Moyo Wovala ndi Kuyang'anira: Moyo wogwiritsidwa ntchito ndi wofunika kwambiri pa ola limodzi. Kuwonongeka kumayesedwa pa kukula kwa roller external diameter ndi flange. Kuyang'ana pafupipafupi ngati pali kutuluka kwa chisindikizo, mawonekedwe osasinthika, kapena kutayika kwa kuzungulira ndikofunikira.
• Malangizo Osinthira: Chifukwa cha malo ovuta ogwirira ntchito, ma roller apansi nthawi zambiri amasinthidwa m'ma seti mbali iliyonse. Kuti galimoto yanu ikhale ndi moyo wabwino komanso magwiridwe antchito, kusintha kwawo kuyenera kugwirizanitsidwa ndi momwe unyolo wa njanji, sprocket, ndi idler zimagwirira ntchito kuti zipewe kuwonongeka mwachangu pazinthu zatsopano.
• Njira Yabwino Yogwirira Ntchito: Kusunga mphamvu yoyenera panjira ndi kupewa kuyenda kosalekeza pamwala wolimba komanso wakuthwa ndikofunikira kwambiri kuti ma roller azikhala nthawi yayitali.

6. Mapeto

TheSANY SSY009115264 SY750 Track Bottom Roller AssemblyChopangidwa ndi HELI (CQCTRACK) chapangidwa ngati gawo lofunika kwambiri lolimba kwa imodzi mwa ma excavator akuluakulu kwambiri m'gulu lake. Malingaliro ake a kapangidwe kake amalimbikitsa moyo wautali wa ntchito pansi pa mikhalidwe yopitilira, yolemera kwambiri, komanso yoipitsidwa kwambiri pogwiritsa ntchito zipangizo zapamwamba zopangira, kutentha kwambiri, makina onyamula katundu wambiri, komanso chisindikizo cholimba cha magawo ambiri. Kwa oyang'anira kukonza migodi ndi eni zida, gawoli likuyimira njira yodalirika, yotsimikizika yogwira ntchito yomwe imathandizira kupanga kofunikira komanso kupezeka kwa ntchito zamakono zamigodi, zomwe zimathandiza mwachindunji kuchepetsa ndalama zonse za umwini wa excavator ya SANY SY750.
