Patent ID: 8210018

Claim:
A method of making a compensation shaft out of a drop-forged shaft blank, said compensation shaft comprising a shaft section having a mass center of gravity which extends eccentric to an axis of rotation of the compensation shaft and which, together with the axis of rotation, creates an unbalanced mass plane which extends substantially perpendicular to a die parting plane, said shaft section comprising a base body and a rib with a height H starting from the base body while extending, with regard to the axis of rotation, in a direction of the unbalanced mass plane oriented away from the mass center of gravity, the method comprising: separating forging ridges formed in the die by trimming the forged shaft blank into a shape close to a final contour of the base body at trimming points on both sides of the unbalanced mass plane, with a distance S 2 between trimming points being substantially smaller than a distance S 1 between the forging ridges prior to separation.
