Abstract
A spherical rod end assembly includes a seal component in the form of a fastener or a washer, or a combination thereof. The seal component has a flexible, resilient skirt, affixed to a metal body, which skirt overlies and seals the cavity within which the ball of the assembly is seated, to exclude dirt and other foreign matter, and to enhance lubrication.
Claims21
A spherical rod end assembly comprising:
- a spherical rod end having a head portion with an opening of spheric cross section therewithin, and with exterior surfaces on opposite sides of said head portion surrounding said opening;
- a ball pivotably seated within said opening of said rod end head portion, said ball having a bore therethrough;
- and fastener means comprised of a plurality of components, a first of said components of said fastener means having a shank portion extending through said bore of said ball, and a second of said components being engaged on said shank portion of said first component, at least one component of said fastener means being a seal component comprised of a rigid body element with a peripheral marginal portion, and a sealing element having an inner portion continuously surrounding said marginal portion of said body element and sealingly affixed thereto, and having a flexible, resilient composite wall portion extending from about said inner portion, said wall portion being outwardly flared and terminating at a flexible peripheral lip in movable sealing engagement with said exterior surface of said head portion adjacent thereto, and being comprised of an outside shell made of a tough, dense, nonporous material, and a lining made of a foraminous material integral with said shell and at least substantially covering the interior face of said wall portion.
A seal component adapted for use in a spherical rod end assembly, or the like, comprising a rigid body element with a peripheral marginal portion, and a sealing element having an inner portion continuously surrounding said marginal portion of said body element and sealingly affixed thereto, and having a flexible, resilient, composite wall portion extending from about said inner portion, said wall portion being outwardly flared and terminating at a flexible outer peripheral lip, and being comprised of an outside shell made of a tough, dense, nonporous material, and a lining made of a foraminous material integral with said shell and at least substantially covering the inner face of said wall portion.
