Crankshaft nigice cyingenzi kizunguruka cya moteri nigice cyingenzi cya moteri. Ukurikije imbaraga nuburemere bifite, igikonjo kigomba kugira imbaraga zihagije kandi zikomeye, kandi hejuru yikinyamakuru bigomba kuba bitarwanya kwambara, gukora kimwe, kandi bifite uburimbane bwiza.

Kuvura Nitriding

Bitewe n'akamaro ka crankshaft, kuvura ubushyuhe bwa crankshaft bifite ibisabwa cyane kugirango déformation. Kubintu byinshi byakozwe na crankshafts, ion nitriding ubushyuhe bukoreshwa mubusanzwe kugirango ubuziranenge bwibicuruzwa. Kubyuma bya karubone cyangwa ibyuma cyangwa ibyuma bito bito, abantu bakunze gukoresha tekinoroji ya nitride (ubushyuhe buke bwa karubone, nitrocarburizing). Umubare munini wimikorere yerekanye ko ubukana no kwinjira murwego rwa nitride bifitanye isano rikabije nubushyuhe, igihe hamwe nubushakashatsi. Ubushyuhe bwo kugenzura ubushyuhe bwa ion yoroshye nitriding bugomba kuba hejuru ya 540 ℃ no munsi yubushyuhe bwo gusaza, kandi ubushyuhe bukwiye bugomba gutoranywa ukurikije ibisabwa byihariye byibice.

Ubushuhe bwa ion nitriding bwo kuvura bufite ihinduka rito, rishobora kwemeza neza guhinduka. Igice cyera kandi cyerurutse kandi cyacengewe ni kimwe, ubunini bwurwego rwinjiye burashobora kugenzurwa, uburyo bwo kuvura ni bugufi, kandi imikorere ni myinshi. Kugeza ubu, itanura rya ion nitriding ryakozwe nisosiyete yacu ryageze ku musaruro mwinshi wa crankshafts, kandi ubwiza bwa nitriding buri hejuru, bwakirwa neza nabakiriya.
