    • Joint section is provided in a connection between a journal section and one of two arms supporting a crankpin and between the crankpin and the other of the arms. In each of the joint sections, a plurality of bolts are arranged along an imaginary circle substantially concentric to the axis of the journal section or crankpin, for fastening together the components. Radius of at least one of the journal section and crankpin is greater than a distance between axis lines of the journal section and crankpin. Blanks of shaft components are worked to provide thereon positioning sections, and the components are provisionally attached together to provide a crankshaft blank. The crankshaft blank is worked and then diassembled to attach thereto float bearings and a connecting rod integrally having a big end. Then, the crankshaft is re-assembled to make a crankshaft assembly.
    • 联接部分设置在轴颈部分和支撑曲柄销之间以及在曲柄销和另一个臂之间的两个臂中的一个之间的连接。 在每个接合部分中,多个螺栓沿着与轴颈部分或曲柄销的轴线大致同心的假想圆布置,用于将部件紧固在一起。 轴颈部分和曲柄销中的至少一个的半径大于轴颈部分和曲柄销的轴线之间的距离。 轴组件的坯件被加工以在其上提供定位部分,并且部件临时地附接在一起以提供曲轴坯料。 加工曲轴坯料,然后将其组装起来,以将浮子轴承和连接杆整体地连接在一起。 然后,将曲轴重新组装成曲轴组件。
