MECHANICAL JOINING OF NITINOL TUBES

The present invention relates to mechanical joining of Nickel Titanium tubes, also known as Nitinol, to other tubular components. Such mechanical joining may be achieved by interpenetration of lobe features between the respective tubes by translating the tubes together on a longitudinal axis, a tran...

Beschreibung
Zusammenfassung:	The present invention relates to mechanical joining of Nickel Titanium tubes, also known as Nitinol, to other tubular components. Such mechanical joining may be achieved by interpenetration of lobe features between the respective tubes by translating the tubes together on a longitudinal axis, a transverse axis, by a combination of translation and rotational motion or by a hinging motion, or by use of the shape-memory effect. The Nitinol superelasticity is used to accommodate the lobe deformation required for assembly and to snap the lobe back into its original shape to complete the mechanical joint. La présente invention concerne l'assemblage mécanique de tubes en nickel-titane, également connu sous le nom de Nitinol, à d'autres composants tubulaires. Un tel assemblage mécanique peut être obtenu par interpénétration de caractéristiques en lobe entre les tubes respectifs par translation des tubes l'un vers l'autre sur un axe longitudinal, un axe transversal, par une combinaison de mouvements de translation et de rotation ou par un mouvement d'articulation, ou par l'utilisation de l'effet de mémoire de forme. La super-élasticité du Nitinol est utilisée pour s'adapter à la déformation des lobes nécessaire pour l'assemblage et le retour en arrière des lobes dans leur forme d'origine pour achever l'assemblage mécanique.
