Abstract
Abstract An isolation mount for damping radial vibration as well as axial vibrations without attendant shear forces to the elastomeric medium. A toroidal casing has a plate extending through its radially outer wall and terminating with flanges on its radially inner edge near a cylindrical core of the casing. Elastomeric O-rings are disposed on either side of the plate so as to be captured between the respective flange and oppositely disposed casing wall. Relative movement between the plate and the casing then results in compressive loads to certain portions of one or both of the O-rings, regardless of whether the relative motion is in the axial or radial direction.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
136 words
An improved isolation mount of the type having first and second mount members connectible to respective elements susceptible to relative axial and radial vibration and having a damping means therebetween to dampen relative axial vibrations wherein the improvement comprises: (a) a cylindrical wall extending axially from the first mount member and at least partially engaging throughout its circumference the damping means; (b) a cylindrical wall extending axially from the second member and at least partially engaging throughout its circumference the damping means, said first mount member cylindrical wall and said second mount member cylindrical wall having said damping means disposed therebetween to dampen relative radial vibrations between the first and second mount means, and wherein said second mount member cylindrical wall limits relative axial movement between said first and second mount members to a predetermined degree.
Claim 2
Dependent Claim
136 words
