ELASTOMERIC SPRING AND METHODS OF MAKING SAME

摘要

A compression spring created from a preform made from an elastomer which is normally free of spring-like characteristics. The preform has an initial predetermined length defined by a longitudinal distance between first and second end portions joined by a mid-portion. The elastomer from which the preform is created has a molecular structure along with a ratio of plastic strain to elastic strain greater than 1.5 to 1. As a result of working the preform, the molecular structure, extending along at least the mid-portion, is oriented so as to transmute the preform into a curved elastomeric spring. Methods of making the elastomeric spring are also disclosed.
