<p>The present invention relates to a ball-type spherical variator mechanism designed to transmit circular rotary motion automatically between shafts and/or axes. It is comprised of two shafts (1, 16) which are arranged coaxially. Each of them can transmit or receive the motion. The transmission of the motion and its variation in a rotary circular motion of a secondary shaft (16) with respect to the primary shaft (1) is obtained as a consequence of the relative motion of three fundamental components which form a sort of bearing. Said components are a spherical ball (15) integral with the primary shaft (1), balls (18) or systems of intermediary balls and an external ring (20) fixed to the secondary shaft (16). Said ring (20) may rotate in both directions on an axis which is perpendicular to the axis which contains the primary and secondary shafts. By rotating the external ring (12) in one direction or the other the motion of the primary shaft (1) is transmitted to the secondary shaft (16). The motion of said ring (12) is obtained by means of actuation control and force mechanisms which are associated with the primary (1) and secondary (16) shafts.</p> |
