I. Pre-Replacement Preparations
Sarudzo Yenzvimbo
Inoda ivhu rakasimba uye rakati sandara (semuenzaniso, kongiri), kudzivirira nzvimbo yakapfava kana yakatenuka kudzivirira midziyo kuti ienderere mberi.
Kugadzirira Tool
Zvishandiso zvinokosha: Torque wrench (inokurudzirwa 270N · m tsanangudzo), hydraulic jack, cheni hoist, pry bar, copper drift, high-simba track shoe bolts.
Chengetedzo giya: Hard hat, anti-slip magirovhosi, magirazi, tsvimbo dzekuchengetedza kuchengetedza.
Equipment Securing
Dzima injini uye ubatanidze bhureki rekupaka. Chengetedza nzira isina kuchinjwa yedivi nemapuranga wedges; shandisa hydraulic tsigiro tsvimbo kudzikamisa furemu kana zvichidikanwa.
II.Excavator Track ShoeRemoval Process
Release Track Tension
Sunungura tensioning cylinder girisi nipple kuti ubvise mafuta ehydraulic zvishoma nezvishoma kusvika track yaserera (sag>5cm).
Bvisa OldExcavatorTrack Shoes
Bvisa madhaka / marara kubva mumigwagwa yenzira (yakakwirira-inomanikidza mvura jet inokurudzirwa).
Sunungura mabhaudhi achipikisa wachi nechipanera che torque; isa mafuta anopinda mukati kana kucheka mabhaudhi ane ngura zvakanyanya.
Bvisa mabhaudhi nealternate kuti udzivise kushushikana mupfungwa pamaketani.
III. NewExcavatorTrack ShoeInstallation
Alignment
Nyatsorongedza zvitsvatrack shoesnema chain link maburi. Pinza mapini uye simbisa munwe-mabhaudhi pakutanga.
Torque Bolt Kusimbisa
Simbisa mabhaudhi mune diagonal kutevedzana kaviri:
Chekutanga: 50% yakajairika torque (~ 135N·m)
Chechipiri: 100% yakajairika torque (270N · m).
Isa thread-locking adhesive kudzivirira vibration-induced kusunungura.
IV. Debugging & Inspection
Gadzirisa Track Tension
Isai girisi muhumburumbira, simudza gwara rimwe 30-50cm kubva pasi, woyera sag (3-5cm). Kunyanya kunetseka kunowedzera kupfeka; kusakwana kukakavara ngozi derailment.
Test Run
Idle tracks kwemaminitsi mashanu. Tarisa uone ruzha rusina kujairika/jamming. Ongororazve bolt torque uye cheni kuita.
Critical Notes
Chengetedzo Chekutanga: Inorambidzwa kutanga kufamba nemakwara akamiswa. Pfeka giya rekudzivirira panguva yese yekusassembly.
Bolt Management: Inosungirwa kushandiswa kweOEM-simba mabhaudhi; kushandisazve mabhaudhi ekare hazvibvumidzwe.
Kuzora: Isa girisi isingapindi mvura (NLGI Giredhi 2+) kumapini emaketani mushure mekuiswa.
Operational Adaptation: Dzivisa mitoro inorema / materu kwemaawa gumi ekutanga. Tarisa chimiro chebhaudhi zuva nezuva panguva yekupwanya.
Zano: Pamamiriro ezvinhu akaoma (semuenzaniso, chain link kupfeka) kana kukanganisa kwehydraulic system, bvunza nyanzvi.
Kuti uwane kubvunza nezve shangu, tapota taura nesu kuburikidza nemashoko ari pasi apa
