Abstract

L'invention se rapporte à un procédé et un système de maintien à lame d'un arbre rotatif (4), comportant un mécanisme de poussée bistable présentant deux positions angulaires stables (P1, P2) et couplé en des extrémités transversales respectivement à une pièce d'interface et à un levier monté sur l'arbre rotatif (4). Dans un tel système, le mécanisme de poussée bistable (10) comporte une ou plusieurs lames déformables en flexion-compression (10a, 10b) selon des états pré-déformés correspondant à l'une et l'autre des positions stables (P1, P2). De plus, chaque lame (10a, 10b) présente des extrémités ou des zones d'extrémité fixées à la pièce d'interface (2) et au levier (3) par des embouts montés en pivotement sur la pièce d'interface (2) et sur le levier (3) parallèlement à l'arbre rotatif (4).The invention relates to a method and a system for holding a rotary shaft (4) with a blade, comprising a bistable pushing mechanism having two stable angular positions (P1, P2) and coupled at transverse ends respectively to a part interface and a lever mounted on the rotating shaft (4). In such a system, the bistable thrust mechanism (10) comprises one or more blades deformable in flexion-compression (10a, 10b) according to pre-deformed states corresponding to one and the other of the stable positions (P1, P2 ). In addition, each blade (10a, 10b) has ends or end areas fixed to the interface piece (2) and to the lever (3) by end pieces mounted to pivot on the interface piece (2) and on the lever (3) parallel to the rotary shaft (4).
