Patent ID: 8881705

Claim:
Mass-balancing transmission of an internal combustion engine, comprising a transmission housing and a balancing shaft with a bearing point at which the balancing shaft is supported in a radial direction in a bearing seat of the transmission housing and with an unbalanced section that is formed integrally with the bearing point of the balancing shaft, the bearing point is set back in the radial direction relative to the unbalanced section, so that, for an outer envelope circle d1 of the bearing point and for an outer envelope circle d2 of the unbalanced section, the following diameter relationship is applicable: d2>d1, and viewed in an axial direction of the balancing shaft, the outer envelope circle d2 of the unbalanced section and the outer envelope circle d1 of the bearing point are offset relative to each other by an eccentricity e, wherein the outer envelope circle d1 of the bearing point is completely within the outer envelope circle d2 of the unbalanced section, so that eccentricity e≦½·(d2−d1).
