Link and bearing for rotary coupling.

摘要

A link for use in a link-type rotary coupling (10). The link has an elastomeric bearing (35) which incorporates a pair of cavities (36C, 36D) that provide discontinuities for preventing the transfer of tensile stresses in the elastomeric layers when the link (10) is tensioned axially while permitting the elastomeric layers (40 to 46) to accept compressive stresses when the link (10) is compressed axially. The resulting link (10) is durable.
