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.
Claims11
An elastomer-containing rod end isolator, comprising, in combination, an outer member having means for connection to a load, and having a rounded pocket therein for receiving a truncated, approximately spherical inner member, said truncated, approximately spherical inner member spaced apart a given distance from and substantially concentric with said outer member, said inner member having two continuous legs each extending in a circular path, disposed adjacent the outer periphery of said inner member and having a flat end surface extending radially toward and terminating short of said outer member, and also having a smooth internal lateral surface,
- and, filling at least part of the space between said inner and outer members, a layer of an elastomer lying between and strongly adhered to both said inner and outer members, and occupying the entire space between said members except for an axially inwardly extending empty mold finger volume, within said elastomer, on each side, said empty mold finger volume on each side forming a groove extending circumferentially and being between said flat end surface of said leg and an inner surface of said outer member wherein said groove extends axially inwardly beyond the width of said leg, and wherein said elastomer contacts said smooth inner lateral surface of said leg.
An elastomer-containing rod end isolator, comprising, in combination, an outer member having means for connection to a load, and having an opening therein for receiving a truncated spherical inner member, said truncated spherical inner member spaced apart a given distance from and concentric with said outer member, said inner member having two continuous narrow legs extending in a circular path, disposed adjacent the outer periphery and having a flat end surface extending radially toward said outer member and also having a smooth internal lateral surface, and, filling the space between said inner and outer members, a volume of an elastomer lying between and strongly adhered to said inner and outer members, except for grooves on each side extending circumferentially and being between said flat end surface of said legs and an inner surface of said outer member wherein said grooves extend axially inwardly beyond the width of said legs, and wherein said elastomer contacts said smooth inner lateral surface of said leg.
