Abstract
A mass balancing mechanism and method of assembly of the same is provided. The mass balancing mechanism compensates mass forces and/or mass moments of inertia of an internal combustion engine and includes two compensation shafts and a traction drive which connects a driven pinion of the crankshaft to drive pinions of the compensation shafts through a traction mechanism. Rotation of the compensation shafts is achieved through a spur gearing with two meshing spur gears arranged between one of the drive pinions and the associated compensation shaft, one of the spur gears being connected to the one drive pinion and the other of the spur gears being connected to the associated compensation shaft. For adjusting the tooth flank lash between the spur gears, an eccentric bearing having a rotationally fixable eccentric raceway is provided by the invention.
