A flexible coupling has an outer bush 2, an intermediate bush 3 and an inner bush 1 coaxially located within one another. One layer 4 of elastomeric material is disposed between and bonded to bushes 1 and 3, and another layer 5 of elastomeric material is disposed between and bonded to bushes 2 and 3. Radial projections 7, 9 on flanges 6, 8 of the bushes 1, 2 and axial projections 10 on bush 3 can interengage to limit relative rotation of the bushes. The coupling can be employed for pivotally linking buckets of a dredge bucket chain. <IMAGE> |
