ABSTRACT:
A drive coupling for interconnecting a pair of rotatable shafts includes a rigid spider that has four coplanar arms. Adjacent arms of the spider are oriented generally perpendicular to each other. A rigid element is disposed between each pair of adjacent arms of the spider. A body of elastomer is secured between each rigid element and each adjacent arm of the spider. One pair of diametrically opposed rigid elements can be connected to one of the rotatable shafts. The other pair of diametrically opposed rigid elements can be connected to the other rotatable shaft. When torque is being transmitted through the coupling, the bodies of elastomer are loaded primarily in compression. Angular misalignment of the shafts is accommodated primarily by shear deflection of the bodies of elastomer.
