CAT-E345B/E349D kutsogolo kwa idler/1156366/2487255/wopanga ndi wogulitsa zida zomangira zolemera

1. Chidule cha Msonkhano wa Front Idler

Themsonkhano wa idler wakutsogolondi gawo lofunika kwambiri mu dongosolo la pansi pa galimoto la Caterpillar E345 ndi E349 excavators. Limagwira ntchito ngati chitsogozo ndi njira yolimbikitsira njanji, kuonetsetsa kuti zikuyenda bwino komanso zikugwirizana bwino panthawi yogwira ntchito yofukula. Chogwirira ntchito chogwirira ntchito chimagwira ntchito limodzi ndi recoil spring ndi hydraulic track adjuster kuti chikhale ndi mphamvu yokwanira yogwirira njanji ndikuyamwa ma shock panthawi yogwira ntchito.

Zigawo zazikulu za dongosololi ndi izi:

• Gudumu Loyendetsa Lotsogola: Gudumu lalikulu lotsogolera lomwe limasunga mzere wolunjika.
• Kasupe Wobwerera M'mbuyo: Amayamwa mphamvu ndi kuchepetsa kupsinjika kwa galimoto yoyenda pansi pa galimoto.
• Chosinthira cha Hydraulic Track: Chimalola kusintha molondola mphamvu ya track.
• Ma Bearings ndi Zisindikizo Zothandizira: Onetsetsani kuti zinthu zikuyenda bwino komanso kupewa kuipitsidwa.

Mafotokozedwe Aukadaulo

Kutengera mitundu yofanana ya Caterpillar (monga 345C), gulu la kutsogolo la idler la E345/E349 mwina lili ndi makhalidwe ofanana:

• Kulemera: Pafupifupi 589 kg (1300 lb) pa chogwirira chonse (kuphatikiza idler, recoil spring, ndi hydraulic adjuster).
• Zipangizo: Kawirikawiri zimapangidwa ndi chitsulo champhamvu kwambiri monga 40Mn/45Mn, chokhala ndi kuuma kwa pamwamba kwa HRC 50-56 komanso kuya kolimba kwa 5-8 mm kuti chipirire malo owuma.
• Kusewera kwa Axial End: Mafotokozedwe ochokera ku mitundu yofanana akuwonetsa kuti pali kusiyana kwa axial pakati pa 0.26 mm (0.010 in) ndi 1.26 mm (0.050 in) kuti igwire bwino ntchito.
• Kupaka mafuta: Kumafuna mafuta a SAE 30-CD (pafupifupi malita 0.625 ± 0.30) kuti mafuta amkati alowe, ndi mafuta enaake (monga katiriji wa mafuta a 5P-0960) pa malo onyamulira akunja.

Njira Zokhazikitsira

Kukhazikitsa bwino ndikofunikira kwambiri kuti zinthu zigwire bwino ntchito komanso kuti zigwire ntchito kwa nthawi yayitali. Nazi njira zofunika kutsatira malangizo a Caterpillar:

1. Kukonzekera: Tsukani bwino malo onse a 配合 kuti muchotse dothi ndi zinyalala. Onetsetsani kuti chogwirira ntchito, zothandizira masika obwerera, ndi ma hydraulic silinda bearing siziwonongeka.
2. Kunyamula ndi Kuyika Malo: Gwiritsani ntchito zida zoyenera zonyamula chifukwa cha kulemera kwake:
   • Kasupe wobwerera m'mbuyo: ~279 kg (615 lb)
   • Chosinthira njira ya hydraulic: ~52 kg (115 lb)
   • Kusonkhanitsa kwathunthu: ~589 kg (1300 lb)

Kukonza ndi Kuyesa

Kukonza nthawi zonse kumathandizira kuti zinthu zikhale zodalirika komanso zimawonjezera nthawi yogwira ntchito:

• Kuyesa Kupanikizika: Cholumikizira chopanda mphamvu chiyenera kusunga mpweya wa 245-265 kPa (36-38 psi) kwa masekondi osachepera 30 chikayesedwa kudzera mu payipi ya pulagi ya chitoliro. Izi zimayang'ana kukhulupirika kwa zisindikizo zamkati.
• Kuyang'anira Zisindikizo: Mukakhazikitsa, onetsetsani kuti zisindikizo za mphira ndi zoyera, zouma, komanso zosapindika. Mphete zosindikizira zachitsulo ziyenera kukhala za sikweya komanso zokhazikika bwino. Pakani mafuta a O-rings ndi mafuta ovomerezeka (6V-4876).
• Kupaka mafuta: Gwiritsani ntchito mafuta ndi mafuta ofunikira okha. Kupaka mafuta molakwika kungayambitse kuwonongeka msanga komanso kulephera kugwira ntchito.
• Kuwunika Kuchotsera: Yang'anirani nthawi zonse kusewera kwa axial end kuti muwonetsetse kuti ikupitirirabe mkati mwa zolekerera zomwe zatchulidwa
