ABSTRACT:
The device comprises a driving hub (4, 18) coaxially connected to one shaft (20) and oscillatably engaging a number of planetary gear elements (8, 25) homogeneously distributed around the axis of said hub. The planetary gear elements (8, 25) are engaged between a driven crown wheel (6, 21) which is coaxially fastened to a second shaft (3, 23) and an intermediate crown wheel (7, 24) oscillatably linked to the driven crown wheel (6, 21). The planetary gear elements (8, 25) driven in rotation by the hub (4, 18), are guided by the driven crown wheel (6, 21) and the intermediate crown wheel (7, 24) according to an elliptic path submitting them to a cyclic reciprocating movement relative to the axis of the driving hub (4, 18). An actuator (12, 35) tends to cause the driven crown wheel (6, 21) and intermediate crown wheel (7, 24) to rotate in opposite ways in view of transmitting resultant forces counteracting their being driven by the hub (4, 18) to the planetary gear elements (8, 25).
