Title (EN) LOAD INDICATING FASTENER INSERT
(FR) INSERT INDICATEUR DE LA CHARGE APPLIQUEE A UN BOULON
Abstract: front page image
(EN)A method and apparatus for determining fastener axial loading includes a fastener insert having an arched bottom surface, which deflects correlative to the level of axial loading. A load indicating mechanism determines axial loading by measuring the amount of deflection experienced by the arched insert. In addition, the arched insert stores elastic energy which is added to the overall elastic energy of the fastener, thereby aiding the fastener integrity during use. The system comprises a zeroing mechanism and full-scale adjustment mechanism for calibration of the system, and an apparatus for measuring in service load.
(FR)L'invention porte sur un procédé et sur un appareil permettant de déterminer la charge axiale appliquée à un boulon et comportant un insert dont la surface inférieure incurvée subit une déflexion fonction de ladite charge, et un mécanisme indicateur déterminant la charge axiale par mesure de la déflexion de l'insert. Par ailleurs l'insert emmagasine de l'énergie élastique qui s'ajoute à celle du boulon et contribue à en maintenir l'intégrité. Le système comprend un mécanisme de mise à zéro, un mécanisme de réglage gradué permettant d'étalonner le système, et un dispositif de mesure de la charge.
