Abstract

L'invention concerne un dispositif de freinage (16) pour un arbre (8) de turbomachine, destiné à limiter une survitesse en rotation de l'arbre (8) autour d'un axe (X) de la turbomachine, comportant au moins un premier organe (17) agencé pour se déplacer suivant une direction déterminée par rapport à une structure fixe (11) de la turbomachine, un deuxième organe (18) lié à l'arbre (8), et un actionneur (19) destiné à pousser le premier organe (17) dans ladite direction déterminée, le premier (22a) et le deuxième (27) organe étant agencés pour coopérer par friction lorsque le premier organe (22a) est poussé par l'actionneur (29, 30, 26a), caractérisé par le fait que l'actionneur comporte un dispositif pyrotechnique (30) agencé pour produire des gaz poussant le premier organe (22a) dans ladite direction déterminée. L'invention concerne aussi une turbomachine utilisant un tel dispositif (16).The invention relates to a braking device (16) for a turbomachine shaft (8) intended to limit an overspeed in rotation of the shaft (8) around an axis (X) of the turbomachine, comprising at least one first member (17) arranged to move in a determined direction relative to a fixed structure (11) of the turbomachine, a second member (18) connected to the shaft (8), and an actuator (19) for pushing the first member (17) in said determined direction, the first (22a) and the second (27) members being arranged to cooperate by friction when the first member (22a) is pushed by the actuator (29, 30, 26a), characterized in that the actuator comprises a pyrotechnic device (30) arranged to produce gases pushing the first member (22a) in said determined direction. The invention also relates to a turbomachine using such a device (16).
