Menene hanyoyin aiwatarwa da yawa don crankshaft wuya shigar da hardening?

1) Wurin crankshaft ba ya jujjuyawa, yi amfani da nau’in inductor mai buɗewa don dumama jaridar da za a yi zafi, da kuma yin quenching na ruwa. Daga baya, an ƙera na’ura mai ɗaukar hoto ta atomatik don yin babban adadin kashe wuyan ƙugiya. Amfanin shine ƙarancin ƙarfin aiki, amma rashin lahani shine yanki mai taurare bai yi daidai ba, kamar faɗin taurare mai taurare a saman matattu na jaridar sanda mai haɗawa da matattun matattu. Yankin yana kunkuntar da sauransu. An yi amfani da wannan tsari sama da shekaru 60, kuma a yanzu ana samar da wasu guraben guraben motoci da taraktoci ta amfani da wannan tsari.

2) Crankshaft juyawa dumama, Semi-annular inductor ana amfani da taro samar a kan Semi-atomatik ko cikakken atomatik crankshaft quenching inji kayan aikin. Amfanin shi ne cewa zafin jiki na yanki mai taurare yana da daidaituwa, kuma nisa ya dace ta hanyar bugun wutar lantarki da sauran fasaha. Amfanin shi ne cewa ana iya buga shi. Fillet quenching, don inganta ƙarfin gajiya na crankshaft, a halin yanzu tsari ne na crankshaft da ake amfani da shi sosai.

3) Ƙaƙwalwar ƙira ba ta jujjuya ba, kuma babban nada mai rabin zobe yana haɗe tare da naɗaɗɗen rabin zobe don dumama jaridar crankshaft, wanda ake kira tsarin Sharp-c. Amfanin shi ne cewa lokacin zafi yana da ɗan gajeren lokaci, lokacin zafi na jarida ya kai kimanin 4s, yanki na kayan aiki ya fi na na’urar kashe wutar lantarki, kuma inductor yana da tsawon rai. Koyaya, wannan tsari baya warware fasahar crankshaft fillet quenching.

4) Crankshaft jujjuya quenching yana ɗaukar nau’in inductor nau’in rabin zobe, wanda kusan ya rufe mujallar crankshaft. Amfanin wannan tsari shine babban aikin dumama da ɗan gajeren lokaci. A halin yanzu, ana amfani da shi ne kawai a kan ƙugiya na mota.
