ABSTRACT:
It comprises a motor shaft (1); a driven member (5), revolving at different speeds; two reduction members (6, 7) comprising each a series of driving elements (10, 11). The two reduction members (6, 7) are coaxial between themselves and with respect to the motor shaft (1) and it comprises at least one rotor (12) driven by the motor shaft (1) comprising at least three pairs of actuating members (15, 16; 17, 18; 19, 20), one of the actuating members (15, 17, 19) of each pair cooperating with driving elements (10) of one of the reduction members (6), whereas the other actuating member (16, 18, 20) of each pair cooperates with driving elements (11) of the other reduction member (7). The relative rotative movement betwen the two reduction members (6, 7) is caused by an instantaneous rotation of the rotor (12), resting on one of the reduction members (6), around a point located on a line connecting the centers of rotation of the actuating members (15, 16) of the pair meshing with the corresponding driving elements (10, 11) and causing the driving of the other reduction member (7).
