Abstract
A mass-balancing transmission of an internal combustion engine (1) is provided, having a transmission housing (8) and a balancing shaft (6) with a bearing point (10, 11) at which the balancing shaft is mounted radially in a bearing seat (12, 13) of the balancing housing, and having an unbalanced section (9) which is formed in one part with the bearing point of the originally shaped balancing shaft. The bearing point is set back radially compared to the unbalanced section with the result that the diameter relationship: d2>d1 applies for the external envelope circle d1 of the bearing point and the external envelope circle d2 of the unbalanced section. Considered in the axial direction of the balancing shaft, the external envelope circle d2 of the unbalance section and the external envelope circle d1 of the bearing point extend offset to one another with an eccentricity of e.
