<p>A kinematism is described, with orbital movement (1) with fixed orientation comprising at least one first (2) and one second (3) motion transmitting means, 'respectively connected to a thrust system (4, 12) and to a driven system (24, 26), mutually facing and mutually frontally cooperating through respective first and second mechanically cooperating means, at least the first transmitting means (2) being rotating around a main rotation axis (R-R), the first mechanically cooperating means being adapted to apply a series of points of force to the second mechanically cooperating means in such a way that a set of positions, instant by instant occupied in the space by each one of the points of force, individually considered, substantially describes a Lemniscate curve as Mobius ring, the thrust system (4, 12) being slanted with respect to the main rotation axis (R-R) and symmetrical with and coaxial to a slanted axis (R' -R' ) around which the curve of the points of force are symmetrically distributed, the kinematism (1) further comprising rotation-preventing means (5, 5' ) adapted to prevent a rotation of a single point of force with respect to the main rotation axis (R-R); the rotation- preventing means (5, 5' ) are composed of at least one rotation-preventing ring (5, 5') constrained to the thrust system (4, 12) through a first pin (6, 6') and a second pin (7, 7 ' ) that are diametrically opposite, the rotation-preventing ring (5, 5') being further constrained to a fixed reference support or carter (8, 14) of the kinematism (1) through a third pin (9, 9') and a fourth pin (10, 10') that are diametrically opposite and arranged orthogonal with respect to the axis of the first pin (6, 6') and the second pin (7, 7').</p> |
