Abstract

A balancing device (100) for an internal com­bustion engine (500) is provided. The balancing device comprises two parallel balance shafts (200, 300) mutually coupled to rotate in opposite directions about a respective rotational axis (X200, X300). Each of the balance shafts (200, 300) comprises an eccentric weight (205, 305) having a center of mass (G205, G305) offset from the rotational axis thereof (X200, X300). The eccentric weights (205, 305) are radially misaligned with each other, and each of the balance shafts (200, 300) comprises a staggered portion (225, 325). Each staggered portion (225, 325) has an axis (Y225, Y325) that is offset from the rotational axis thereof (X200, X300), thereby defining a throw (230, 330) of the balance shaft (200, 300), which is radially aligned with the eccentric weight (305, 205) of the other balance shaft (300, 200) and is arranged to allow the rotation of said eccentric weight (305, 205).
