Abstract
The paper presents a solution for coupling two shafts with non-coplanar axes using an intermediary element. The intermediary part is connected with the ground via a spherical pair while, to the shafts, two point-surface contacts are used. For the proposed model, the positional analysis, a CAD model and numerical validation of the solution are presented. The advantage of the tetrapod coupling consists in constructive simplicity and controlled reliability by the possibility of replacing the higher pairs of the intermediary element with linkages with lower pairs.
