Abstract
The invention relates to a method for the production of a drop-forged balancing shaft for a mass balancing gear of an internal combustion engine. The balancing shaft has an unbalanced plane formed by the rotational axis thereof and an eccentric mass center of gravity, and at least one bearing journal, the outer lateral surface of which serves as a track for a rolling bearing supporting the balancing shaft in the internal combustion engine. To this end, the balancing shaft is to be forged in a forging die having a parting plane extending in the direction of the rotational axis and rotated in relation to the unbalanced plane.
