Ichain hub sprocketye-excavator ithwala umthwalo omkhulu wempembelelo kwinkqubo yokusebenza.Xa i-excavator ijika, imeko yoxinzelelo ayithandeki ngakumbi. Ngokubanzi, xa i-excavator iqhuba i-350,000 h okanye kunjalo, i-chain hub sprokcet amazinyo e-sprocket angawa okanye aphuke, kunye nokunxiba imilo yezinyo kunye nesiganeko esaphukileyo kwindawo edibeneyo. kweziqingatha ezibini ze-sprocket ye-hub ye-chain ibaluleke kakhulu.Ibonakaliswe ngokuziqhelanisa ukuba ukusebenzisa i-welding yokufaka ukulungisa i-ring gear ilula kwaye ikhawuleza, kwaye inokuqinisekisa ukusebenza komatshini wonke.
Ngokomonakalo we-chain hub sprocket, misela indawo yomgodi oqingqiweyo kunye necandelo elonakeleyo eliza kutshintshwa, uze unqumle icandelo lamazinyo ukuba litshintshwe ngokusika igesi.Yenza ukufakwa ngokweengxenye ze-sprocket ezifuna ukulungiswa, okanye unqumle icandelo elingcono lamazinyo e-sprocket ukusuka kwindawo ehambelanayo yenye i-ring ring endala kunye nesiqinisekiso se-pitch, kwaye unqumle i-groove shape kwi-junction.misela indawo yokufaka umngxuma wokulungisa, uyibethe kwaye uyilungise kwindawo ehambelanayo ye-hub hub sprocket , kwaye ubeke ingqalelo ukuqinisekisa ukuchaneka kwendawo yokulungisa umngxuma.Ukuze uqinisekise ukuba i-weld inamandla aphezulu kwaye inako ukumelana nempembelelo enkulu kunye nokunyakaza, ububanzi be-Φ4 mm edibeneyo ye-507 electrode ikhethiwe.I-electrode kufuneka ibhakwe i-1 h kwi-250 ~ 350 ℃ ngaphambi kokusetyenziswa.Ax3500 DC umatshini we-arc welding we-DC reverse welding method, okwangoku yi-130 ~ 140 A.
Ngaphambi kwe-welding, fudumeza umphezulu we-welding malunga ne-200 ℃ kunye ne-2 enkulu ye-welding ye-gas gun. Nge-backfire weld, i-weld yokugqibela inokucaphukisa i-weld yangaphambili, enenzuzo yokuphelisa i-microstructure eqinile eyenziwa yi-weld yangaphambili.Ngenxa yokuba i-groove enkulu, i-weld yokuqala kufuneka idityaniswe kancinci kancinci ukunciphisa ububanzi bokudibanisa kunye nokunciphisa umxholo wekhabhoni yensimbi.Xa usebenzisa i-welding, i-electrode ijika phambili malunga ne-15 ° kwaye iqhubela phambili kumgca othe tye.Xa uvala i-arc, kufuneka kuhlawulwe ingqalelo ekuzaliseni umgodi we-arc ukuphepha ukuvelisa i-arc pit crack.Emva kwe-welding, khawuleza udibanise i-weld kunye namacala omabini ngesando esincinci esicacileyo ukuze ukhulule uxinzelelo kude kubekho iindawo ezixineneyo zokuphonswa kwi-weld. .Qhubeka ukuwelda xa i-weld iphola malunga ne-200 ℃.Indlela ye-welding ye-weld nganye emva kwe-weld yokuqala iyafana neyokuqala.I-electrode inokujikwa kancinci.Ukuze ugweme ama-pores, musa ukujingi kakhulu. Emva kwe-welding, ukuze kupheliswe izicubu eziqinileyo kunye noxinzelelo, i-welding seam kunye namacala omabini afudunyezwe malunga ne-600 ~ 650 ℃ nge-oksijini yomlilo we-acetylene, kwaye ubushushu bugcinelwe. 20 imiz.Emva koko, i-welding seam igutyungelwe nge-asbestos, i-hydrated ye-lime powder okanye isanti eyomileyo, kwaye i-welding seam ipholile ngokucothayo ukuya kwi-room temperature.Sebenzisa ivili lokugulisa ukugulisa i-weld, ukwenzela ukuba ukulungiswa kwe-chain hub sprocket kugqityiwe.
