Abstract

A mass equalization gear mechanism of an internal combustion engine is provided, having a gear mechanism housing (8) with bearing points (16, 17, 18), at least one equalization shaft (6) with a drive section (9) and an imbalance section (12) and rolling bearings (10, 11, 15) by which the equalization shaft is mounted in the bearing points. In this context, the gear mechanism housing is hydraulically sealed, with the result that the imbalance section and at least one of the rolling bearings is hydraulically separated from the drive section and is provided with autonomous lubrication.
