A mechanism for varying the relative angular velocity of two shafts (31,32) in a proportionally continuous manner is described. The main feature of this mechanism is to comprise, between said two shafts (31,32), a transmission unit (12) comprising at least one plurality of members (19, 20) rotating about an axis, each of said members (19, 20) being able to establish a connection engagement between one of said two shafts (31,32) and a rotating element (13,14) over a limited extent of rotation of said shaft, the distance of said members from the axis of said one of said two shafts or of said rotating element, when in said connection engagement position, being able to be varied by adjustment means (7) in order to vary the relative angular velocity of said two shafts in a proportionally continuous manner. |
