I-CAT-E345B/E349D i-front idler assembly/1156366/2487255/umkhiqizi wezingxenye ze-chassis zokwakha ezisindayo kanye nomhlinzeki

1. Ukubuka Konke Komhlangano We-Front Idler

Iinhlangano ye-idler yangaphambiliiyisici esibalulekile ohlelweni lwe-undercarriage lwe-Caterpillar E345 kanye ne-E349 excavators. Isebenza njengesiqondiso kanye nendlela yokuqinisa imizila, iqinisekisa ukusebenza okubushelelezi kanye nokuqondana okufanele ngesikhathi semisebenzi yokumba. I-idler assembly isebenza ngokubambisana ne-recoil spring kanye ne-hydraulic track adjuster ukuze kugcinwe ukucindezeleka okuhle kakhulu kwemizila futhi kuncishiswe ukushaqeka ngesikhathi sokusebenza.

Izingxenye ezibalulekile zesistimu zifaka:

• Isondo Lokuvilapha Ngaphambili: Isondo eliyinhloko eliqondisayo eligcina ukuhambisana komzila.
• Intwasahlobo Yokubuyela Emuva: Imunca imiphumela futhi inciphise ukucindezeleka engaphansi kwesihlalo.
• Isilungisi Sethrekhi Ye-Hydraulic: Sivumela ukulungiswa okunembile kokucindezeleka kwethrekhi.
• Ama-Bearings kanye nama-Seals asekelayo: Qinisekisa ukujikeleza okubushelelezi futhi uvimbele ukungcola.

Imininingwane Yobuchwepheshe

Ngokusekelwe kumamodeli afanayo e-Caterpillar (njenge-345C), i-front idler assembly ye-E345/E349 cishe inezici ezifanayo:

• Isisindo: Cishe ama-589 kg (1300 lb) wokuhlanganiswa okuphelele (kufaka phakathi idler, intwasahlobo yokuhlehla, kanye ne-hydraulic adjuster).
• Izinto: Ngokuvamile zenziwe ngensimbi enamandla amakhulu njenge-40Mn/45Mn, enobulukhuni bomphezulu obuyi-HRC 50-56 kanye nokujula okuqinile okungu-5-8 mm ukuze kumelane nezimo ezihudulayo.
• I-Axial End Play: Imininingwane evela kumamodeli afanayo iphakamisa ukuthi isikhala se-axial siphakathi kuka-0.26 mm (0.010 in) okungenani kanye no-1.26 mm (0.050 in) esiphezulu ukuze kusebenze kahle 2.
• Ukugcotshwa: Kudinga uwoyela we-SAE 30-CD (cishe amalitha angu-0.625 ± 0.30) ukuze kugcotshwe ngaphakathi, kanye namafutha athile (njengekhatriji yamafutha ye-5P-0960) ezindaweni zangaphandle zokuthwala.

Izinqubo Zokufaka

Ukufakwa okufanele kubalulekile ukuze kuhlale isikhathi eside futhi kusebenze kahle. Nazi izinyathelo ezibalulekile ezisekelwe eziqondisweni ze-Caterpillar:

1. Ukulungiselela: Hlanza zonke izindawo ze-配合 kahle ukuze ususe ukungcola kanye nemfucumfucu. Qinisekisa ukuthi i-idler, izisekelo zesipilingi sokubuyela emuva, kanye nama-hydraulic cylinder bearing awanamonakalo 1.
2. Ukuphakamisa Nokubeka Indawo: Sebenzisa imishini yokuphakamisa efanele ngenxa yesisindo esinzima:
   • Intwasahlobo yokubuyela emuva: ~279 kg (615 lb)
   • Isilungisi sethrekhi ye-hydraulic: ~52 kg (115 lb)
   • Ukuhlanganiswa okugcwele: ~589 kg (1300 lb)

Ukugcinwa Nokuhlolwa

Ukugcinwa njalo kuqinisekisa ukuthembeka futhi kwandisa impilo yesevisi:

• Ukuhlolwa Kokucindezela: I-idler assembly kufanele igcine umfutho womoya ongu-245-265 kPa (36-38 psi) okungenani imizuzwana engu-30 uma ihlolwa nge-pipe plug port. Lokhu kuhlola ubuqotho bezimbobo zangaphakathi.
• Ukuhlolwa Kwesivalo: Ngesikhathi sokuhlanganiswa, qiniseka ukuthi izivalo zobuso zerabha zihlanzekile, zomile, futhi azisontekile. Izindandatho zesivalo zensimbi kumele zibe yisikwele futhi zihlale kahle. Gcoba izindandatho ze-O nge-lubricant evunyelwe (6V-4876).
• Ukugcoba: Sebenzisa amafutha namafutha anconyiwe kuphela. Ukugcoba okungalungile kungaholela ekugugeni nasekuhlulekeni kusenesikhathi.
• Ukuhlolwa Kokuqedwa: Qapha njalo i-axial end play ukuqinisekisa ukuthi ihlala ngaphakathi kwemingcele ethile
