I-crankshaft iyingxenye eyinhloko ejikelezayo yenjini futhi ingxenye ebaluleke kakhulu yenjini. Ngokwamandla nomthwalo ewuthwalayo, i-crankshaft idinga ukuba namandla anele kanye nokuqina, futhi ingaphezulu lejenali lidinga ukumelana nokugqoka, lisebenze ngokufanayo, futhi libe nokulingana okuhle.

Ukwelashwa kwe-Nitriding

Ngenxa yokubaluleka kwe-crankshaft, ukwelashwa kokushisa kwe-crankshaft kunezidingo eziqinile kakhulu zokuguqulwa. Kuma-crankshaft akhiqizwa ngobuningi, ukwelashwa kokushisa kwe-ion nitriding ngokuvamile kusetshenziswa ukuthuthukisa ikhwalithi yomkhiqizo. Ngensimbi ye-carbon steel noma i-cast iron noma i-low alloy steel, abantu bavame ukusebenzisa ubuchwepheshe be-ion soft nitriding (izinga lokushisa eliphansi ikhabhoni, i-nitrocarburizing). Inombolo enkulu yemikhuba ibonise ukuthi ubulukhuni kanye nokungena kwesendlalelo se-nitrided kunobudlelwane obunzima nokushisa, isikhathi nokugxila. Ibanga lokulawula izinga lokushisa le-ion nitriding ethambile kufanele libe ngaphezu kuka-540℃ futhi libe ngaphansi kwezinga lokushisa lokuguga, futhi izinga lokushisa elifanele kufanele likhethwe ngokuya ngezidingo ezithile zezingxenye.

Ukwelashwa kokushisa kwe-ion nitriding kune-deformation encane, engaqinisekisa ngempumelelo ukuguquguquka. Isendlalelo esimhlophe nesigqamile kanye nesendlalelo se-permeated siyafana, ubukhulu bongqimba obufakwe ngaphakathi buyalawuleka, umjikelezo wokwelapha mfushane, futhi ukusebenza kahle kuphezulu. Njengamanje, isithando somlilo se-ion nitriding esikhiqizwe yinkampani yethu sesizuze ukukhiqizwa okukhulu kwama-crankshafts, futhi izinga le-nitriding liphezulu, elamukelwa kahle ngamakhasimende.
