Gear shaft forgings zvinoenderana nechimiro cheaxis, shaft inogona kukamurwa kuita crankshaft uye yakatwasuka shaft mapoka maviri.Zvinoenderana nekutakura kugona kwe shaft, inogona kukamurwazve kuita:
(1) Shaft inotenderera, kana ichishanda, inotakura nguva yekukotama uye torque.Ndiyo shaft yakajairika mumichina, senge shaft mune zvakasiyana-siyana zvinoderedza.
(2) mandrel, anoshandiswa kutsigira zvikamu zvinotenderera zvinongotakura nguva yekukotama uye usafambise torque, kumwe kutenderera kwemandrel, senge njanji yemotokari shaft, imwe mandrel haitenderere, senge inotsigira pulley shaft, nezvimwe.
(3) drive shaft, inonyanya kushandiswa kuendesa torque pasina kukotama nguva, senge refu optical shaft ye crane mobile mechanism, shaft yekutyaira yemota, nezvimwe.
