<p>COMPRESSION MOUNTING A compression mounting comprises a body of elastomer and a pair of load-transmitting devices that engage and cover two opposed and spaced apart surfaces of the elastomeric body. The two load-transmitting devices are disposed and configured to expose a circumferential surface of the body of elastomer. At least a circumferential portion of the surfaces so exposed is completely covered and enclosed by a shell or housing. The shell includes a filamentary structure that provides a plurality of substantially parallel and juxtaposed filament portions oriented to circumscribe the surface of the elastomeric body. The filament portions are less extensible than the elastomer of the elastomeric body. A matrix material encases the filament portions and flexibly bonds adjacent filament portions to one another. The shell snugly fits the surface of the elastomeric body and is more resistant to circumferential expansion than the elastomeric body. The shell thus impedes, at least, the circumferential expansion of the elastomeric body in response to compression loads exerted on the body through the loadtransmitting devices. As a result, the capacity of the mounting to support compressive loads is increased relative to a mounting incorporating unconfined elastomer. The matrix material permits adjacent filament portions to move in parallel planes relative to each other so that the shell and the mounting can deflect in response to torsional loads.</p> |
