Crankshaft nikimwe mubice byingenzi muri moteri yaka imbere, kandi ubuzima bwumurimo akenshi bugena ubuzima bwumurimo wa moteri yaka imbere. Mu 1920, Isosiyete y'Abanyamerika Clark yakoresheje ikorana buhanga rya induction ryavumbuwe vuba aha kugirango ikinyamakuru crankshaft gikomere, cyatezimbere cyane kurwanya abrasion ya crankshaft, bityo bizamura ubuzima bwakazi bwa moteri yaka imbere.

Mu myaka ya vuba aha, kuvunika umunaniro wa crankshaft byagaragaye cyane, kandi inkomoko yumunaniro ahanini iboneka kumpande zegeranye zumutwe wikinyamakuru gihuza ikinyamakuru. Kubera iyo mpamvu, abayikora benshi basabye ibisabwa kugirango bongere imbaraga zumunaniro wa crankshaft. Urufunguzo rwo kunoza umunaniro wa crankshaft ni ukongera imbaraga zo kwikuramo ibisigisigi bya crankshaft. Kwinjiza gukomera kwa crankshaft yuzuye (harimo ibinyamakuru) nuburyo bwatoranijwe bwo kubona impagarara nini zisigaye zo kwikuramo za> 600MPa zuzuye. Isosiyete y'Abayapani yakoze urukurikirane rw'ibizamini byo kunaniza umunaniro kuri moteri yo gutwika imbere. Ubushakashatsi bwerekanye ko induction izengurutswe ikomye cyane ifite imbaraga z'umunaniro mwinshi (996MPa), imbaraga z'umunaniro uzengurutswe ni uwa kabiri (890MPa), naho igikonjo cya nitride ni icya gatatu (720MPa). Ibigo byabanyamerika nabyo bifite amakuru asa. Kuzimya Crankshaft muri rusange ikoresha kuzimya "igice cyo guhinduranya inductor", kizwi kandi nk'uburyo bwo kuzimya Elotherm (Elotherm). Ni uko sensor yomekwa ku kinyamakuru, hanyuma igikonjo gishyuha kandi amazi akazimya mugihe cyo kuzunguruka (hari nigihe usanga ikinyamakuru crankshaft gishyuha ubushyuhe bwo kuzimya hanyuma kigahinduka pisine kugirango gikonje kandi kizimye). Ubu buryo ntabwo bworohereza gusa kwinjira no gusohoka kwa sensor ya crankshaft, byoroshya ibikorwa byigikoresho cyo kuzimya imashini, ariko kandi bikemura no gucamo umwobo wamavuta, ubugari butaringaniye bwagace gakomeye, uburebure butaringaniye bwurwego rukomeye Ibibazo nkibinini Guhindura.

Abantu mu nganda muri rusange bemeza ko uburyo bwo kuzimya Eluosen ari iterambere rikomeye mu buhanga bwo kuzimya crankshaft. Amakuru yerekana ko gukomera kwinjizwa ryibinyamakuru bya crankshaft bishobora kongera ubuzima bwa moteri kugeza kumasaha 8000, mugihe kuzimya induction yibinyamakuru na fillets bishobora kongera ubuzima bwa moteri kumasaha 10,000. Tekinoroji yingenzi igomba gukemurwa kugirango igere kuzimya ni tekinoroji yo gukwirakwiza ingufu. Kuzimya Crankshaft "igice cya kabiri cya inductor" kuzimya bikubiyemo ikoranabuhanga ryinshi, nko gutanga amashanyarazi inshuro nyinshi, ibikoresho byo kuzimya imashini hamwe na inductor, nibindi. Iri koranabuhanga naryo ni ingenzi cyane, ariko ubwo buhanga bwakemuwe bwa mbere mugihugu cyanjye muntangiriro ya 1980.

Ikigaragara ni uko kuzimya ubushyuhe bwa crankshaft kuzuza bigomba gukorwa neza. Imbaraga zo gushyushya imbere imbere yigitereko ninyuma yigitereko zigomba guhinduka, ni ukuvuga, imbaraga zimbere yigitereko zigomba kuba nini, kandi imbaraga zo hanze yikigega zigomba kuba nto. Iri koranabuhanga ryitwa tekinoroji yo gukwirakwiza ingufu. Inguni zizengurutse inguni nini nini ntoya yazimye. Ikoranabuhanga nugutanga ingufu 100% mugihe ushyushye imbere yigitereko, na 60% (cyangwa 70%) mugihe ushyushya hanze yigitereko, kandi nkuko igikonjo kizunguruka, inguni yiyongera (cyangwa igabanuka) kumubare runaka buri 15 ° Imbaraga.
