Iyo crankshaft chikamu chakakosha cheinjini. Chinhu chayo chinogadzirwa nekabhoni structural simbi kana nodular cast iron. Iine zvikamu zviviri zvakakosha: bhuku guru, rodhi rekubatanidza tsvimbo (nezvimwe). Iyo huru yejenari yakaiswa pane cylinder block, iyo yekubatanidza tsvimbo mutsipa yakabatana nehombe yemusoro wetsvimbo yekubatanidza, uye diki rekubatanidza tsvimbo gomba rakabatana necylinder piston, inova yakajairwa crank slider mechanism.

Iyo huru yekubereka ye crankshaft inowanzonzi yakakura bearing. Kufanana netambo yekubatanidza, iyo zvakare inotsvedza yakakamurwa kuita hafu mbiri, inova iyo huru fani (yekumusoro uye yakaderera mabhengi). Gwenzi repamusoro rinotakura rinoiswa mugomba guru rekutakura chigaro chemuviri; iyo yepasi inotakura yakaiswa muhombe yekutakura chivharo. Iyo huru inotakura chivharo uye chikuru chinotakura chivharo chemuviri chakabatanidzwa pamwe chete nemabhoti makuru anotakura. Izvo zvinhu, chimiro, kuisirwa uye kugadzika kweiyo huru inotakura zvakangofanana neiyo yekubatanidza tsvimbo inotakura. Kuti uendese mafuta kune yekubatanidza tsvimbo huru inotakura musoro, maburi emafuta nemagirovha emafuta anowanzo kuvhurwa pane hombe yekutakura padhi, uye iyo yepasi inotakura iyo huru inotakura kazhinji haina kuvhurika nemakomba emafuta uye migero yemafuta nekuda kwekuremerwa kwepamusoro. . Paunenge uchiisa iyo huru yekubereka kwe crankshaft, teerera kune chinzvimbo uye kutungamira kwekubereka.
