Phunzirani kukonza ma excavator chain hub sprocket mu mphindi 5

Thechain hub sprocketya excavator imanyamula katundu wokhudzidwa kwambiri pogwira ntchito.Pamene chofukula chimapendekeka, kupsinjika maganizo kumakhala kosasangalatsa. Kawirikawiri, pamene chofukula chikugwira ntchito kwa maola 350,000 kapena kuposerapo, mano a chain hub sprokcet sprocket amatha kugwa kapena kusweka, ndipo mawonekedwe a dzino amavala ndi kusweka kwa dzino pa gawo lolumikizana. mwa theka ziwiri za chain hub sprocket ndizovuta kwambiri. Zatsimikiziridwa ndi chizolowezi kuti kugwiritsa ntchito kuwotcherera lowetsani kukonza mphete ndizosavuta komanso zachangu, ndipo zimatha kutsimikizira kugwira ntchito kwa makina onse.
Malinga ndi kuwonongeka kwa unyolo likulu sprocket , dziwani malo a dzenje lokhazikika ndi gawo lowonongeka kuti lisinthidwe, ndiyeno kudula gawo la mano kuti m'malo ndi kudula gasi.Pangani zoyikapo molingana ndi magawo a sprocket omwe akuyenera kukonzedwa, kapena dulani gawo labwinoko la mano a sprocket kuchokera pagawo lofananira la giya lina lakale la mphete ndi chitsimikizo cha phula, ndikudula mawonekedwe a groove pamphambano.dziwani malo a dzenje loyikapo, limenyeni ndikulikonza mu gawo lolingana la chain hub sprocket, ndipo tcherani khutu kuti muwonetsetse kuti malo opangira dzenje ali olondola. kupirira kukhudzidwa kwakukulu ndi kugwedezeka, m'mimba mwake wa Φ4 mm olowa 507 electrode amasankhidwa.Elekitirodi iyenera kuphikidwa kwa 1 h pa 250 ~ 350 ℃ musanagwiritse ntchito.Ax3500 DC arc kuwotcherera makina DC reverse kuwotcherera njira, panopa ndi 130 ~ 140 A.
Pamaso kuwotcherera, preheat kuwotcherera pamwamba pafupifupi 200 ℃ ndi 2 lalikulu mpweya kuwotcherera mfuti.Ndi backfire weld, chowotcherera otsiriza akhoza kukwiyitsa weld wakale, amene n'kopindulitsa kuthetsa anaumitsa microstructure opangidwa ndi weld wakale.Chifukwa poyambira ndi chachikulu, chowotcherera choyamba chiyenera kuwotcherera pang'ono pang'ono kuti achepetse m'lifupi mwa kuphatikizika ndi kuchepetsa mpweya wazitsulo. Mukamagwiritsa ntchito kuwotcherera, electrode imapendekera kutsogolo pafupifupi 15 ° ndikupita patsogolo molunjika.Mukatseka arc, chidwi chiyenera kulipidwa pakudzaza dzenje la arc kuti musapangitse ming'alu ya arc. Pambuyo pakuwotcherera, mwachangu nyundo yowotcherera ndi mbali zonse ziwiri ndi nyundo yaying'ono yoloza kuti muchepetse kupsinjika mpaka pakhale madontho wandiweyani. .Pitirizani kuwotcherera pamene kuwotcherera kuzizira pafupifupi 200 ℃.Njira yowotcherera ya weld iliyonse itatha kuwotcherera koyamba ndi yofanana ndi yoyamba.Elekitirodi imatha kugwedezeka pang'ono.Pofuna kupewa pores, musagwedezeke kwambiri. Pambuyo kuwotcherera, kuti athetse minofu yowuma ndi kupsinjika, msoko wowotcherera ndi mbali zonse ziwiri zimatenthedwa mpaka 600 ~ 650 ℃ ndi lawi la oxygen la acetylene, ndipo kutentha kumasungidwa. 20 min.Kenako, kuwotcherera msoko wokutidwa ndi asibesitosi, hydrated laimu ufa kapena mchenga wouma, ndi kuwotcherera msoko pang'onopang'ono utakhazikika kwa firiji.Gwiritsani ntchito gudumu kupukuta kupukuta kuwotcherera, kuti unyolo likulu sprocket kukonza anamaliza.
