Ngokusekelwe kokuhlangenwe nakho kwethu komkhakha, singathanda ukwabelana ngolwazi oluthile mayelana nezinto zokusetshenziswa kanye nokwelashwa okushisa kwama-crankshafts esitimela.
Izinto zokusetshenziswa eziyinhloko zama-crankshafts esitimela sikadizili yinsimbi engumgunyathi ne-ductile iron. Ama-crankshaft ensimbi eyakhiwe, ngenxa yamandla awo aphezulu nokuqina, asetshenziswa kakhulu ezitimeleni zesimanje zikadizili ezinamandla aphezulu. I-42CrMoA ne-42CrMo4 ziphakathi kwezinto ezisetshenziswa kakhulu kuma-crankshaft esitimela sikadizili ngenxa yamandla azo aphezulu nokuba lukhuni. Ngenxa yokuthi ama-crankshafts athwala imithwalo emikhulu eshintshanayo ngesikhathi sokusebenza kwangempela, izinto zokusetshenziswa kufanele zibe namandla aqine kakhulu futhi akhiqize, ukunwetshwa, ukuncishiswa kwendawo, namandla anomthelela. Ngaphezu kwalokho, izinto ngokwazo kufanele zihlangabezane nokuhlanzeka okuphezulu (okuqukethwe kwe-hydrogen nokufakwa okungezona ezensimbi, njll.) kanye nokunemba okuphezulu (okuhlangabezana namazinga emboni kaloliwe efana ne-TB/T3475.1-2017). Izinqubo zokwelashwa kokushisa (i-crankshaft rolling, i-surface nitriding, kanye ne-medium-frequency induction harding) nazo zidinga amazinga aphezulu okumelana nokuguga kanye nokumelana nokukhathala. Ngenxa yemikhawulo engokwemvelo kanye nokukhubazeka, ama-ductile iron crankshaft awasasetshenziswa ezitimeleni zika-diesel.
