Seal for rotating means

Abstract

There is disclosed sealing means for effecting a seal between two adjacent members, one of which rotates relative to the other, comprising a convoluted resilient metal ring bonded to an elastomeric support member; the convoluted wall of the ring provides radial resiliency whereby dimensional displacement of the sealed members may be accommodated and a substantially leak-free fit obtained, thereby preventing fluid leakage between the members, while at the same time allowing the seal to tolerate high peripheral speeds between the members and to resist and compensate for wear. An elastomeric support member acts as a supplemental seal to the ring and provides additional elasticity for accomodating lateral displacement of the rotatable member, while maintaining an effective fluid-tight seal.
