Crankshaft chimwe chezvikamu zvakakosha muinjini yekupisa yemukati, iyo musana weinjini, ndicho chikamu chakakosha kutakura mutoro wekukanganisa uye kufambisa simba.

Iyo crankshaft inonyanya kuumbwa nemberi kweiyo crankshaft, iyo huru shaft mutsipa, iyo yekubatanidza tsvimbo yemagazini, crank, bharanzi block, kumashure kweiyo crankshaft, nezvimwewo. iyo piston yekubatanidza tsvimbo boka mune yekunze inobuda torque, uye inogona kutyaira vharafu yeinjini yekupisa yemukati uye zvimwe zvakasiyana siyana. Mamiriro ekushanda uye kushushikana kwe crankshaft yakaoma kwazvo, uye inoiswa pasi peiyo komputa mhedzisiro ye periodic shanduko mukumanikidza gasi, centrifugal simba uye inertial simba panguva yebasa. Naizvozvo, mukugadzirisa nekugadzira, kurongeka kwedimensional, kurongeka kwenzvimbo uye kushata kwepamusoro kwechikamu chimwe nechimwe che crankshaft zvine zvakakwirira zvinodiwa.

Iyo crankshaft inowanzokandwa kubva pakati kabhoni simbi, yepakati kabhoni alloy simbi kana ductile iron
