Crankshaft ndiye gawo lalikulu lozungulira la injini komanso gawo lofunikira kwambiri la injini. Malingana ndi mphamvu ndi katundu umene imanyamula, crankshaft iyenera kukhala ndi mphamvu zokwanira komanso zolimba, ndipo pamwamba pa magaziniyi sayenera kuvala, kugwira ntchito mofanana, ndikukhala bwino.

Chithandizo cha nitriding

Chifukwa cha kufunikira kwa crankshaft, chithandizo cha kutentha kwa crankshaft chimakhala ndi zofunika kwambiri pakuwonongeka. Kwa ma crankshaft opangidwa ndi misa, chithandizo cha kutentha kwa ion nitriding nthawi zambiri chimagwiritsidwa ntchito kukonza zinthu. Pazitsulo za carbon kapena iron iron kapena low alloy steel, anthu nthawi zambiri amagwiritsa ntchito teknoloji ya ion soft nitriding (carbon carbon, nitrocarburizing). Zochita zambiri zawonetsa kuti kuuma ndi kulowa kwa nitrided wosanjikiza kumakhala ndi ubale wopitilira muyeso ndi kutentha, nthawi komanso kukhazikika. Kuwongolera kutentha kwa ion nitriding yofewa kuyenera kukhala pamwamba pa 540 ℃ ndi pansi pa kutentha kwa ukalamba, ndipo kutentha koyenera kumayenera kusankhidwa malinga ndi zofunikira za magawo.

Chithandizo cha kutentha kwa ion nitriding chimakhala ndi mawonekedwe ang'onoang'ono, omwe amatha kuwonetsetsa kuti mapindikidwewo. Choyera choyera ndi chowala komanso chopindika ndi yunifolomu, makulidwe amtundu wa permeated amatha kulamuliridwa, chithandizo chamankhwala chimakhala chachifupi, ndipo mphamvu yake ndi yapamwamba. Pakalipano, ng'anjo ya ion nitriding yopangidwa ndi kampani yathu yakwanitsa kupanga ma crankshafts ambiri, ndipo khalidwe la nitriding ndilokwera, lomwe limalandiridwa bwino ndi makasitomala.
