Abstract:
1. An unbalanced shaft for the compensation of at least one of inertial forces or mass moments of inertia of an internal combustion engine, comprising: an unbalanced portion, a mass center of gravity of which runs eccentrically with respect to an axis of rotation of the unbalanced shaft for generating a shaft imbalance, a bearing portion adjacent to the unbalanced portion, and a bearing ring which is attached to the bearing portion and an outer surface area of the bearing ring serves as a raceway for rolling bodies of a rolling bearing rotationally supporting the unbalanced shaft and an inner surface area of which, in a bearing circumferential region extending in an imbalance direction, is set back radially with respect to an outer enveloping circle of the unbalanced portion, and for the purpose of mounting the bearing ring onto the bearing portion, the following geometric relations are provided: with d d e=a center offset between d
