Thechain hub sprocketchemucheri chinotakura hukuru hwekukanganisa mukuita basa.Kana iyo yekuchera inonyunguduka, mamiriro ekushushikana anowedzera kusafarirwa.Muzhinji, kana mucheki achimhanya kwe350,000 h kana zvakadaro, cheni hub sprokcet sprocket mazino anogona kudonha kana kutsemuka, uye chimiro chezino chinopfeka uye zino rakatyoka chiitiko pachikamu chejoinhi. yezvikamu zviviri zve chain hub sprocket zvakanyanya kukomba.Zvakaratidzirwa nekudzidzira kuti kushandisa kuisa welding kugadzirisa ring gear iri nyore uye inokurumidza, uye inogona kuvimbisa kushanda kwemuchina wose.
Maererano nekukuvadza kweketani hub sprocket , sarudza nzvimbo yegomba rakagadziriswa uye chikamu chakakanganisika chinotsiviwa, uye wozogura chikamu chemazino kuti chitsiviwa nekucheka gasi.Ita zvinopinza zvinoenderana nezvikamu zve sprocket zvinoda kugadziriswa, kana kucheka chikamu chirinani chemazino e sprocket kubva pachikamu chinowirirana cheimwe yekare giya remhete ine vimbiso yepitch, uye cheka chimiro chegorofu pajunction.sarudza nzvimbo yekuisa gomba rekugadzirisa, rova uye ugadzirise muchikamu chinoenderana chechain hub sprocket, uye teerera kuti uone chokwadi chekugadzirisa gomba.Kuitira kuti uve nechokwadi chokuti weld ine simba rakakwirira uye rinogona kutsungirira kukanganisa kukuru uye kudengenyeka, dhayamita ye Φ4 mm yakabatana 507 electrode inosarudzwa.I electrode inofanira kubikwa kwe 1 h pa 250 ~ 350 ℃ isati yashandiswa.Ax3500 DC arc welding machine DC reverse welding method, ikozvino i130 ~ 140 A.
Usati welding, preheat welding surface kusvika 200 ℃ ne 2 hombe gasi welding pfuti.Ne backfire weld, iyo yekupedzisira weld inogona kushatirisa yaimbova weld, iyo inobatsira kubvisa yakaomeswa microstructure yakagadzirwa neyaimbova weld.Nekuti groove iri yakakura, iyo yekutanga weld inofanira kunge yakashongedzwa zvishoma zvishoma kuti ideredze hupamhi hwekusanganiswa uye kuderedza kabhoni yesimbi.Paunenge uchivhara arc, kutarisisa kunofanirwa kubhadharwa kuzadza gomba rearc kudzivirira kuburitsa arc gomba rakatsemuka.Mushure mekucheka, kurumidza nyundo weld uye mativi ese maviri nenyundo diki yakanongedza kuzorodza kushushikana kusvika kune dense pitting spots mu weld. .Ramba uchipisa kana weld yatonhora inenge 200 ℃. Nzira yewelding yeweld yega yega mushure mekutanga weld yakafanana neyeyekutanga weld.Iyo electrode inogona kuzungunuswa zvishoma.Kuti udzivise pores, usazununguke zvakanyanya. Mushure mekugadzira, kuti ubvise iyo yakaoma tishu uye kushushikana, iyo welding musono uye mativi ese ari maviri inopisa kusvika 600 ~ 650 ℃ neokisijeni acetylene murazvo, uye kupisa kunochengeterwa. 20 min.Zvadaro, musono welding wakafukidzwa neasbestos, hydrated lime poda kana jecha rakaoma, uye welding seam inotonhora zvishoma nezvishoma kusvika kune imwe nzvimbo yekushisa.Shandisa vhiri rekuporesa kuti uporese weld, kuitira kuti chain hub sprocket kugadziriswa kwapera.
