A planetary gear system comprises an input shaft (5), an output shaft (1) and at least one meshing gear-pair (Z1, Z2) connecting the input shaft (5) to the output shaft (1). One of the gears (Z2) of said gear-pair is eccentrically mounted relative to the input shaft (5). The system includes at least one crank member (2) having a first bearing end engaged with the eccentrically mounted gear (Z2) and a second bearing end, offset with respect to the first, which is engaged with either a further gear (Z3) or a fixed member (9, Figure 2). The system is provided with balancing means (6). <IMAGE> |
