ABSTRACT:
A seal ring of resilient material is disposed in a groove to provide a seal in a clearance space between a stationary member and a rotating member. The seal ring is cold-formed to provide axial undulations, prior to assembly, so that the seal ring has a greater effective width than the groove width whereby, during assembly, the seal ring is placed in an interference fit within a groove in one member and is contained within the groove to facilitate the assembly of the members without damage to the seal ring. Initial operation of the members, with oil having a temperature above ambient, causes the seal ring to relax from the cold-formed configuration to permit the seal to move radially in the grooved member until sealing contact with the other member occurs thereby restricting leakage between the members.
