Title (EN) FLEXURAL PIVOT
(FR) PIVOT DE FLEXION
Abstract:
(EN) A flexural pivot is disclosed. The flexural pivot can include a first flexure support member, a second flexure support member rotatably coupled to the first flexure support member for relative rotation about a first axis, and a third flexure support member rotatably coupled to the second flexure support member for relative rotation about a second axis, in addition the flexural pivot can include a plurality of cross blade flexures rotatably coupling the flexure support members to one another. Each cross blade flexure can have first and second flexible blade units that have flexible blades arranged in a cross configuration. The flexible blade units can have blade supports disposed at opposite ends of the flexible blades to facilitate coupling the flexible blade units to the flexure support members. The flexible blade and the blade supports of each flexible blade unit can form a monolithic structure.
(FR) L'invention concerne un pivot de flexion. Le pivot de flexion peut comprendre un premier élément de support de flexion, un deuxième élément de support de flexion accouplé rotatif au premier élément de support de flexion pour une rotation relative autour d'un premier axe, et un troisième élément de support de flexion accouplé rotatif au deuxième élément de support de flexion pour une rotation relative autour d'un deuxième axe, de plus le pivot de flexion peut comprendre une pluralité de flexions de lame transversale accouplant de manière rotative les éléments de support de flexion entre eux. Chaque flexion de lame transversale peut avoir des première et seconde unités de lame flexible qui ont des lames flexibles agencées selon une configuration transversale. Les unités de lame flexible peuvent avoir des supports de lame disposés aux extrémités opposées des lames flexibles pour faciliter l'accouplement des unités de lame flexibles aux éléments de support de flexion. La lame flexible et les supports de lame de chaque unité de lame flexible peuvent former une structure monolithique.
