Abstract:
1. A balancing shaft for a single- or multi-cylinder engine comprising at least one unbalanced weight portion and at least one bearing point, which is associated with the at least one unbalanced weight potion, the bearing point comprising a radial peripheral surface which extends, only in part, over a periphery of the bearing point so that a centrifugal force resulting from rotation of the balancing shaft is situated in a region of the bearing point which is formed by the peripheral surface extending, in part, over the periphery of the bearing point, and comprising a raceway which surrounds the partially formed peripheral surface of the bearing point and is connected to the bearing point by a non-positive and/or positive and/or cohesive joint, wherein the peripheral surface of the bearing point comprises a receiving region for receiving the raceway, and at least an axially outer edge region or at least an annular region of the raceway which is connected to at least an axial side surface of the receiving region with a non-positive and/or positive and/or cohesive fit or in that the raceway comprises a support portion in the axial direction on its running surface and adjacent thereto, which support portion extends in the radial direction, at least in part, but does not extend over the entire periphery and is connected to the receiving region or the main body.
