Crankshaft, kaya ndi crankshaft ya injini yamagalimoto, crankshaft ya injini yam'madzi kapena pampu yapampu ya mafakitale, imayendetsedwa ndi kusinthasintha kopindika ndikusinthana katundu panthawi yozungulira. Magawo owopsa a crankshaft, makamaka fillet yosinthira pakati pa magazini ndi crankshaft. Panthawiyi, crankshaft nthawi zambiri imasweka chifukwa cha kupsinjika kwakukulu. Chifukwa chake, machitidwe amafunikira kuti crankshaft ikhale ndi mphamvu zokwanira kuwonetsetsa kuti crankshaft sisweka panthawi yogwira ntchito. Pakalipano, kusintha kukana kutopa kwa crankshaft poyang'ana kuwombera kwagwiritsidwa ntchito mosiyanasiyana, ndipo zotsatira zake ndi zokhutiritsa.

Poyerekeza ndi zolakwika za chikhalidwe chogubuduza, ndiko kuti, chifukwa cha kuchepa kwa teknoloji yopangira crankshaft, ngodya zozungulira za magazini iliyonse zimakhala zovuta kuti zifanane ndi odzigudubuza, omwe nthawi zambiri amayambitsa kuluma ndi kudula pamakona ozungulira, ndipo crankshaft itatha kugudubuza imapunduka kwambiri. ,osati mogwira mtima. Limagwirira wa kuwombera peening ndi ntchito kuwombera particles ndi m'mimba mwake mosamalitsa ndi mphamvu inayake. Pansi pa kayendedwe ka mpweya wothamanga kwambiri, kutuluka kwa kuwombera kumapangidwa ndikupopera mosalekeza pamwamba pazitsulo za crankshaft, monga nyundo ndi nyundo zosawerengeka, kotero kuti pamwamba pa crankshaft ndi nyundo. Amapanga mapindikidwe amphamvu kwambiri a pulasitiki, amapanga wosanjikiza wozizira wowumitsa ntchito. M'mawu osavuta, chifukwa crankshaft imakhudzidwa ndi mphamvu zosiyanasiyana zodulira makina panthawi yokonza, kugawa kwapang'onopang'ono pamtunda wake, makamaka pakusintha kwa gawo la crankshaft, kumakhala kosagwirizana kwambiri, ndipo kumakhala kupsinjika kwakanthawi pakugwira ntchito. ndikosavuta kupsinjika Kupsinjika kwa dzimbiri kumachitika ndipo moyo wotopa wa crankshaft umachepa. Njira yowomberedwa ndikuwongolera kupsinjika komwe kudzakhalako komwe magawowo adzakumana nawo pakadutsa kagawo kakang'ono ka ntchito poyambitsa kupsinjika kwanthawi yayitali, potero kumathandizira kukana kutopa komanso moyo wotetezeka wa chogwiriracho.

Kuphatikiza apo, ma crankshaft forging blanks amapangidwa mwachindunji kuchokera kuzitsulo zachitsulo kapena zitsulo zopangidwa ndi zitsulo zotentha. Ngati njira zopangira ndi kugubuduza sizikuyendetsedwa bwino, nthawi zambiri pamakhala kugawikana kwa zigawo zomwe zikusowekapo, mbewu zowoneka bwino za kapangidwe koyambirira, komanso kugawa kosafunikira kwa zomanga zamkati. ndi zina zofooka zachitsulo ndi bungwe, potero kuchepetsa kutopa moyo wa crankshaft, ndi ndondomeko kulimbikitsa akhoza konza dongosolo la bungwe ndi bwino kwambiri ntchito yake kutopa.
