Patent ID: 8375916

Claim:
A mass balancing mechanism for balancing mass forces and/or mass torques of an internal combustion engine, said mechanism comprising a balancing shaft comprising an axis of rotation, a mass center of gravity spaced from said axis of rotation and further comprising at least one bearing peg on which said balancing shaft is mounted for rotation in a mounting location of the internal combustion engine, said bearing peg including two axially spaced cylindrical bearing peg sections that define a recess which extends substantially or entirely outside of the axis of rotation relative to the mass center of gravity, the mounting location is configured as a rolling bearing, said bearing peg projects radially beyond at least one adjoining shaft section at least within a fractional periphery, and at least one radially outwards extending rib is arranged within this fractional periphery between the shaft section and an associated one of the bearing peg sections, said rib being arranged at an angle of inclination to the axis of rotation of the balancing shaft and serving as a shovel for pressure or suction delivery of lubricating oil mist into the rolling bearing which is produced during operation of the internal combustion engine.
