Abstract
Ecrou comprenant au moins une jauge de déformation, boulon comportant au moins un tel écrou et dispositif de mesure d’une précha r ge exercée par un tel boulon L'invention a pour objet un écrou (22) comprenant au moins une jauge de déformation (30) positionnée sur la surface périphérique extérieure (24) de l’écrou et configurée pour générer au moins un signal en fonction d’une déformation de l’écrou (22) selon une direction de mesure parallèle à l’axe (A22) de l’écrou (22). L’invention a également pour objet un boulon comportant au moins un tel écrou ainsi qu’un dispositif de mesure d’une précharge exercée par un tel boulon. L’invention permet d’ajuster précisément la précharge au moment du serrage du boulon. Figure 2Nut comprising at least one strain gauge, bolt comprising at least one such nut and device for measuring a precha r ge exerted by such a bolt The subject of the invention is a nut (22) comprising at least one strain gauge ( 30) positioned on the outer peripheral surface (24) of the nut and configured to generate at least one signal as a function of a deformation of the nut (22) along a direction of measurement parallel to the axis (A22) of the nut (22). The invention also relates to a bolt comprising at least one such nut as well as a device for measuring a preload exerted by such a bolt. The invention makes it possible to precisely adjust the preload when tightening the bolt. Figure 2
