Crankshaft, kaya ndi crankshaft ya injini yamagalimoto, crankshaft ya injini yam'madzi kapena pampu yamagetsi yamafakitale, imagwira ntchito yophatikizika yopindika ndikusinthiratu katundu wa torsion panthawi yozungulira. Magawo owopsa a crankshaft, makamaka fillet yosinthira pakati pa magazini ndi crank Nthawi zina, crankshaft imasweka chifukwa cha kupsinjika kwakukulu.

Chifukwa chake, machitidwe amafunikira kuti crankshaft ikhale ndi mphamvu zokwanira kuwonetsetsa kuti crankshaft sisweka panthawi yogwira ntchito. Pakalipano, kugwiritsa ntchito kuwomberedwa kuwombera kusintha kukana kutopa kwa crankshafts kwagwiritsidwa ntchito kwambiri pamagwiritsidwe osiyanasiyana, ndipo zotsatira zake ndi zokhutiritsa.

Poyerekeza ndi chilema cha njira yachikhalidwe yogubuduza, chifukwa cha kuchepa kwa ukadaulo wa crankshaft processing, ngodya zozungulira za magazini iliyonse zimakhala zovuta kufananiza ndi chogudubuza, chomwe nthawi zambiri chimayambitsa kuluma kwa ngodya zozungulira, ndi crankshaft pambuyo pakugudubuza. imapunduka kwambiri, osati bwino. Njira yowombera ndikugwiritsa ntchito ma pellets okhala ndi mainchesi oyendetsedwa bwino komanso mphamvu zina kuti apange ma pellets amtundu wina pansi pa kuthamanga kwa mpweya wothamanga kwambiri ndikuwapopera mosalekeza pazitsulo za crankshaft, monga kumenya nyundo ndi zing'onozing'ono zosawerengeka. nyundo zopangira pamwamba pa crankshaft Pangani mapindikidwe amphamvu kwambiri a pulasitiki ndikupanga ntchito yozizira yolimba. Kunena mwachidule, chifukwa crankshaft imayendetsedwa ndi mphamvu zosiyanasiyana zodulira makina panthawi yokonza, kugawanika kwa nkhawa pamtunda wake, makamaka kusintha kwa gawo la crankshaft, kumakhala kosagwirizana kwambiri, ndipo kumakhala ndi zovuta zina panthawi ya ntchito. ndi zophweka Kupsinjika maganizo kumachitika ndipo moyo wotopa wa crankshaft umachepa. Njira yowomberedwa ndikuyambitsa kupanikizika kwapang'onopang'ono kuti muchepetse kupsinjika komwe gawolo lidzalandira m'tsogolomu, potero kumathandizira kukana kutopa komanso moyo wotetezeka wa chogwiriracho.

Kuphatikiza apo, ma crankshaft forging blanks amapangidwa mwachindunji kuchokera kuzitsulo zachitsulo kapena kupangidwa kuchokera kuzitsulo zotentha. Ngati njira zopangira ndi kugubuduza sizikuyendetsedwa bwino, nthawi zambiri pamakhala kugawanika kwa zigawo, mbewu zowoneka bwino za kapangidwe koyambirira, komanso kugawa kwamkati kosamveka m'malo osasowekapo. Ndi zolakwika zina zazitsulo ndi zamagulu, potero kuchepetsa kutopa kwa crankshaft, njira yolimbikitsira imatha kukonzanso kapangidwe kake ndikuwongolera kwambiri kutopa kwake.
