Abstract
A tube form assembly includes an inner member and an outer member. Each of the inner and outer members has an offset which creates a cavity therebetween. During assembly of the tube form assembly, an adhesive is located in the cavity and squeezed out and through the adjacent bond lines between the inner member and outer member. The pressurization and flow of adhesive outward from the cavity facilitates removal of air bubbles, as well as prevents the introduction of air bubbles into the bond line.
Claims15
A tube form assembly, comprising:
- an attachment member configured to couple to a structure exhibiting oscillatory motion;
- an elastomer member coupled to an outer surface of the attachment member;
- an inner member coupled to the elastomer member;
- an outer member for translatingly receiving at least a portion of the inner member;
- an inner offset adjoining an outer surface of the inner member, the inner offset including an arcuate portion thereof such that a cross-section of the arcuate portion of the inner offset taken along a longitudinal axis of the tube form assembly is curved,
- wherein the arcuate portion and the outer surface of the inner member meet at a non-arcuate corner portion of the inner member;
- an outer offset located in an inner surface of the outer member, the outer offset being arcuate such that a cross-section of the outer offset taken along the longitudinal axis of the tube form assembly is curved;
- a cavity formed between the inner offset and the outer offset;
- and
- an adhesive located between the inner member and the outer member;
- wherein assembly of the inner member and the outer member causes a portion of the adhesive to be squeezed away from the cavity.
A method for assembling a tube form assembly, the method comprising:
- providing an attachment member configured to couple to a structure exhibiting oscillatory motion;
- providing an elastomer member coupled to an outer surface of the attachment member;
- providing an inner member coupled to the elastomer member and an outer member, the inner member and the outer member having contours which create a cavity therebetween, wherein the cavity is formed by a first offset in the inner member and a second offset in the outer member, the first offset including an arcuate portion thereof such that a cross-section of the first offset taken along a longitudinal axis of the tube form assembly is curved, and the second offset being arcuate such that a cross-section of the second offset taken along a longitudinal axis of the tube form assembly is curved, wherein the arcuate portion of the first offset and an outer surface of the inner member meet at a non-arcuate corner portion of the inner member;
- applying an adhesive in the cavity;
- and
- pressing the inner member and the outer member together so that a volume of the cavity decreases, thereby squeezing a portion of the adhesive towards one or more extremities of the tube form assembly.
