Abstract: A flexible coupling between two shafts. The flexible coupling includes a spacer element inserted between an actuating shaft or a drive shaft and an actuated shaft or a load shaft. The flexible coupling includes an assembly of articulated connecting rods at both points of connection. The articulated connecting rods respectively linking the two elements to be connected. All of the connecting rods on both ends being articulated in ball joints used to facilitate the rotation of the connecting rods in any direction.

Abstract: A flexible coupling between two shafts, including a spacer element inserted between the actuating shaft or drive shaft and the actuated shaft or load shaft, and an assembly of articulated connecting rods at both points of connection (between the drive shaft and the spacer element and between same and the load shaft), said articulated connecting rods respectively linking the two elements to be connected, being tangentially arranged in relation to the coupling shaft and angularly spaced around same, a circumferential phase shift of 60°, all of the connecting rods on both ends being articulated in ball joints used to facilitate the rotation of the connecting rods in any direction, so that the coupling can adapt itself to all of the potential disalignments that may occur, both radially and axially, or When there is play between the spacer and the load, since, on the opposite side, an axially arranged connecting rod prevents the occurrence of axial play between same.
