Abstract
Une cale (22) destinée à bloquer le pivotement d'une queue (4) d'une aube dépendant d'une virole de support (2) comporte une entaille (26) dans laquelle la queue de l'aube est engagée, et deux flancs encadrant cette entaille, dont l'un (27) est en appui entre un épaulement (31) de la virole (2) et un méplat (6) de la queue (4) de l'aube, alors que l'autre flanc (28) est libre, environné de jeux (35, 36). Cette disposition permet un montage isostatique qui se prête au libre choix de l'angle de calage de l'aube d'après la direction de l'entaille (26). Le montage et le démontage sont facilités par l'isostaticité de cet assemblage.A wedge (22) intended to block the pivoting of a tail (4) of a blade dependent on a support ring (2) comprises a notch (26) in which the tail of the blade is engaged, and two flanks framing this notch, one of which (27) is supported between a shoulder (31) of the ferrule (2) and a flat (6) of the tail (4) of the blade, while the other flank (28) is free, surrounded by games (35, 36). This arrangement allows isostatic mounting which lends itself to the free choice of the setting angle of the blade according to the direction of the notch (26). The assembly and disassembly are facilitated by the isostaticity of this assembly.
