Heavy duty resilient coupling assembly

A resilient coupling assembly comprising a housing member having a generally cylindrical bore opening to the exterior thereof, a shank member having a generally cylindrical portion received in said bore with an annular space between said bore and said cylindrical portion of said members, a one-piece circumferentially continuous bushing of a resilient elastomeric material received between said members and constructed and arranged with a generally circular outer surface portion in engagement with said cylindrical bore of said housing member and a generally inner surface portion in engagement with said cylindrical portion of said shank member, said bushing having a plurality of circumferentially spaced retainer passages each extending generally radially through said bushing and opening into both said cylindrical bore and said cylindrical portion of said members, and a plurality of bearing inserts each received in only one of said retainer passages and between said cylindrical bore and cylindrical portion of said members, each of said bearing inserts being dimensioned to provide a clearance between each bearing insert and said cylindrical bore and cylindrical portion of said members when said members are unloaded, said bushing being compressible to at least the extent of said clearance without rupture of said resilient elastomeric material.
