Abstract

Amortisseur mécanique à inertie. Le mouvement axial relatif de deux dispositifs de jonction d'une entretoise est converti en mouvement de rotation d'un arbre qui entraîne un élément à inertie rotatif. Les éléments à inertie sont reliés par un ressort hélicoïdal, de sorte que l'élément qui est entrainé directement par l'arbre entraîne l'autre. A un seuil prédéterminé d'accélération, l'élément à inertie qui est entraîné par le ressort est en retard, de sorte que le diamètre du ressort augmente et que ses spires frottent contre la paroi du carter qui l'entoure en produisant un freinage Application aux dispositifs de jonction des tubes contenant les cartouches de combustible dans une centrale nucléaire et destinés à limiter l'amplitude de leur mouvement en cas de tremblement de terreMechanical inertia damper. The relative axial movement of two junction devices of a spacer is converted into rotational movement of a shaft which drives a rotating inertia member. The inertia elements are connected by a coil spring, so that the element which is driven directly by the shaft drives the other. At a predetermined threshold of acceleration, the inertia element which is driven by the spring lags, so that the diameter of the spring increases and its turns rub against the wall of the casing which surrounds it, producing braking Application junction devices for tubes containing fuel cartridges in a nuclear power plant and intended to limit the amplitude of their movement in the event of an earthquake
