Elastic coupling with hub and ring - has hub and ring grooves forming bearing shells for elastomer rollers turning freely

摘要

The elastic coupling comprises elastomer rollers (3) with axes (4) parallel to those (5,6) of the hub (5) and outer ring (6) between which they are enclosed. The rollers fit in grooves (8,9) in both. The grooves form bearing shells in which the rollers turn freely on their axes. The external diameter of the hub can be only slightly less than the internal one of the ring, so as to form a seat for movement between them with the roller removed. The depth of the bearing shells and the clearance between hub and ring can be such that when in use the rollers can turn freely on their axes. ADVANTAGE - Greatly increased roller life.
