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) and to a driven system (5), mutually facing and mutually frontally cooperating through respectively a first (6) and a second (7) mechanically cooperating means, at least the first transmitting means (2) rotating around a main rotation axis (R-R), the first mechanically cooperating means (6) being adapted to apply a series of points of force to the second mechanically cooperating means (7) so that a set of positions, instant by instant occupied in the space by each one of such points of force, individually considered, substantially describes a Lemniscate curve as Mobius ring, the thrust system (4) being slanted with respect to the main rotation axis (R-R) and symmetrical and coaxial with a slanted axis (R' -R' ) around which the curves of such points of force are symmetrically distributed, further comprising rotation-preventing means (8) adapted to prevent the rotation of the single point of force with respect to the main rotation axis (R-R). |
