Abstract
A flexible shaft coupling device having two hubs with teeth extending from each hub toward the other hub. The teeth are in parallel alignment and spaced from each other. There are projections on a flexible elastomeric belt which fill the gaps between adjacent pairs of teeth. The projections are connected by a flexible pleated connector to absorb start-up forces and increase the life of the belt. A retainer band is mounted around the belt to keep the belt securely in place.
Claims17
A shaft coupling comprising:
- first and second hubs, each having respective first and second faces;
- first and second pluralities of teeth extending from the respective first and second faces, the teeth on the first face in parallel alignments with the teeth on the second face, the aligned teeth forming gaps between adjacent pairs of aligned teeth;
- a split, flexible belt having opposed edges and an inside and an outside surface, a plurality of spaced projections on the inside surface, each of the projections occupying one of the gaps between adjacent pairs of aligned teeth,
- connecting means comprising a bridging member having a pleated cross-sectional configuration for connecting at least two of the spaced projections to each other, the connecting means having a flexible portion for absorbing impact forces transmitted between the first and second hubs, and
- an endless retainer band adapted for mounting around the belt to retain the belt in a securely wrapped condition around the teeth.
