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.
Claims4
A mass equalization gear mechanism of an internal combustion engine comprising a gearbox housing with bearing points, at least one balancing shaft with a drive section and an imbalance section, and rolling bearings by which the balancing shaft is supported at the bearing points, the gearbox housing is sealed hydraulically such that the imbalance section and at least one of the rolling bearings are separated hydraulically relative to the drive section and are provided with autonomous lubrication, the mass equalization gear mechanism is arranged within an oil pan of the internal combustion engine, an axis of the balancing shaft runs geodetically underneath a nominal oil circuit operating level of the internal combustion engine in a rest state thereof and above a nominal oil level of the autonomous lubrication when the engine is in the rest state.
