Ibha Yensimbi Eyindilinga ye-SAE8620H /GB 20CrNiMo Steel Bar
Izici
Insimbi ye-8620 alloy yakhiwe (ngokuhlelwa kokwehla kwephesenti) insimbi, ikhabhoni, i-silicon, i-molybdenum, i-manganese, i-nickel, i-chromium, isulfure ne-phosphorus.Lezi zakhi zesithako kufanele zibe phakathi kwamaphesenti athile esisindo ukuze udale ingxubevange engu-8620.Kunconywa ukuthi insimbi iqiniswe yi-carburization elandelwa namafutha, ngokuphambene namanzi, cisha.Inesilinganiso esimaphakathi sokuminyana kwama-alloys ensimbi angu-.28 lb. per inch square, nakuba amandla ayo aqinile - inani lesisindo engakwazi ukulibamba ngaphambi kokuphuka - liphansi, ku-536.4 Mpa.Isilinganiso samandla ensimbi ama-alloys angama-758 kuya ku-1882 Mpa.
Lapho ingxubevange ye-8620 ishiswe ngendlela efanele - ishisiswe kumazinga okushisa amisiwe bese ivezwa kumenzeli oqukethe ikhabhoni, inqubo enezela ungqimba olwengeziwe lwekhabhoni ngaphandle kwensimbi, ngaleyo ndlela iyenze ibe namandla - isetshenziselwa ukwenza umshini onjalo. izingxenye njengamagiya, ama-crankshafts, namaringi egiya.I-Carburized 8620 alloy inamandla futhi ihlala isikhathi eside, yingakho ikhethwa kulezi zingxenye.

Isicelo sebha yensimbi ye-SAE8620H
Okuvame ukusetshenziselwa ukukhiqiza izingxenye ezibalulekile ezinamandla amakhulu kanye nepulasitiki enhle, kanye nokukhiqiza izingxenye ezibalulekile ezinezidingo ezikhethekile zokusebenza ngemuva kokwelashwa kwe-nitriding:
Ama-arbors, ama-bushings, abalandeli be-Cam, izikhonkwane zokugqoka, ama-bearings, ama-sprockets, amagiya nama-shafts, izinja ze-Clutch, ama-Compressor bolts, ama-extractors, ama-fan shafts, ama-Heavy Duty Gears, ama-Pump Shafts, ama-Sprocket, ama-Tappets, ama-Wear pin, ama-Wire Guide njll. Noma ingasetshenziselwa izinhlelo zokusebenza ezishubile kakhulu ezingangcwatshwanga kodwa ngokuqiniswa nokufutheka.Isetshenziswa kakhulu yiyo yonke imikhakha yezimboni yezingxenye namashafti adinga ukumelana nokugqoka okuphezulu, amandla aphezulu aphezulu kanye nezakhiwo ezinomthelela.
