Abstract
A flexible shaft coupling device having two hubs with jaws extending from each hub toward the other hub. A flexible elastomeric belt or cushions fill the gaps between adjacent pairs of jaws. A retaining ring is mounted around the belt or cushions to keep the belt or cushions securely in place. There are a plurality of locking pins adjacent to the edges of the retaining ring and preferably on the interior surface of the ring. These are received in grooves cut in the exterior surface of the belt. When the retaining ring is placed over the belt, the belt is retained between the locking pins. Raised portions or nubs are placed at the entrance and exits of the grooves so that when the ring is rotated with respect to the belt, the locking pins pass over the nubs to securely lock the retaining ring around the edges of the belt. Alternatively the edges of the belt or cushions are tapered to engage the pins in locking engagement.
