摘要：
PROBLEM TO BE SOLVED: To construct large a counterweight without increasing the processes and the costs. SOLUTION: This forged crankshaft includes a counterweight 8 provided with a gradient for mould releasing in such an arrangement that the gradient is large (θ1) in the part nearer the mould mating surface P and small (θ1) in the farther part. This varying gradient for mould release allows large size construction of counterweight using a finite space. The process does not include any mechanical processing after forging, which can prevent increase in the processes and the costs.
