Abstract

Un ensemble de réglage de pas (100), destiné à un ensemble rotor (20) sans roulement, comprend un tube de couple (36) enveloppant un raccord à plaque de flexion (22). L'ensemble de réglage de pas (100) comporte un roulement de centrage (70) destiné à centrer une extrémité interne (38) du tube de couple (36) par rapport au raccord à plaque de flexion (22), de façon que ce roulement decentrage (70) définisse un point de pivotement (110) du tube de couple autour duquel ce tube de couple (36) tourne par rapport au raccord à plaque de flexion (22). Une bielette de commande de pas (48) est reliée mécaniquement à un bras de commande de pas (46) pour transmettre des commandes de pas au tube de couple (36). La bielette et le bras de commande de pas (48, 46) définissent un point de pivotement de commandes (116), et un mécanisme de déplacement (102 ou 140), combiné avec le roulement de centrage (70), réalisent le déplacement en translation du centre géométrique (120) du tube de couple (36) par rapport au tube de couple et aux points depivotement de commandes (110, 116). Des cales de réglage (102) ou un dispositif à vérin (140) permet le mouvement en translation du tube decouple (36).
