Abstract
An elastomer-containing rod end isolator. The isolator includes a handle for connection to a load and inner and outer members. The outer member is a pocket and the inner member is spherical or nearly so. The pocket and the inner member are concentric and the inner member has two continuous exterior legs extending in a circular path. An elastomer fills most of the space between members.
Claims9
An isolator comprising:
- an outer member including an axial outer periphery defining an opening disposed about a central axis and a pocket defined in a radial interior surface of the outer member that extends from the outer periphery through the outer member, wherein the pocket includes a first section disposed contiguous with and extending from the outer periphery that is parallel to the central axis and a second section disposed contiguous with and extending from the first section that is non-parallel to the central axis;
- an inner member disposed substantially concentric within said outer member, the inner member including an axial outer face defining an aperture disposed about the central axis and a radial outer surface that extends across the inner member, wherein the outer surface includes a first portion disposed contiguous with and extending from the outer face that is parallel to the central axis and a second portion disposed contiguous with and extending from the first portion that is non-parallel to the central axis;
- and an elastomeric isolator disposed between said inner and outer members and substantially occupying a space defined between said inner and outer members, the elastomeric isolator including an axially inwardly extending groove defined by groove walls separated by a gap width, wherein the groove extends circumferentially about a periphery of the elastomeric isolator and is disposed between the first section and the first portion, wherein a groove depth defined by an axial extent of the groove walls is greater than the gap width and the groove walls are parallel to the central axis.
An isolator comprising:
- an outer member including an axial outer periphery defining an opening disposed about a central axis and a pocket defined in a radial interior surface of the outer member that extends from the outer periphery through the outer member, wherein the pocket includes a major section that is non-parallel to the central axis;
- an inner member disposed substantially concentric within said outer member, the inner member including an axial outer face defining an aperture disposed about the central axis and a radial outer surface that extends across the inner member, wherein the outer surface includes a first portion disposed contiguous with and extending from the outer face that is parallel to the central axis and a second portion disposed contiguous with and extending from the first portion that is non-parallel to the central axis;
- and an elastomeric isolator disposed between said inner and outer members and substantially occupying a space defined between said inner and outer members, the elastomeric isolator including an axially inwardly extending groove defined by groove walls separated by a gap width, wherein the groove extends circumferentially about a periphery of the elastomeric isolator and, wherein a groove depth defined by an axial extent of the groove walls is greater than the gap width and the groove walls are parallel to the central axis.
An elastomeric isolator comprising a unitary body of an elastomer material, said unitary body having a radial load-carrying portion and an angular misalignment portion, wherein the angular misalignment portion includes an axially inwardly extending groove defined by groove walls separated by a gap width, wherein the groove extends circumferentially about a periphery of the elastomeric isolator and, wherein a groove depth defined by an extent of the groove walls is greater than the gap width and an outer wall of the radial load-carrying portion is non-parallel to the groove walls.
