Abstract
A spring (15) of angular shape is placed between the lug (17) of a connecting rod (10) controlling the orientation of a stator blade and the pivot (3) of said blade, such that its edge (18) bends against one edge face (19) of the connecting rod (10) and the washer (16) moves the pivot (3) in the play of the bore (21) of the connecting rod and sets and maintains the contact between two plane faces (12 and 13), so as to reduce the differences in angular displacements between the connecting rod and pivot due to the play remaining in the bore (21).
Claims4
Stator blade (2) pivoting arrangement in a turbomachine, comprising a blade pivot (3) having one end projecting outside the stator and comprising a plane face section (8), and a control connecting rod (10) engaged onto the end of the blade pivot via a bore limited by plane faces (13) associated with the plane faces (12) of the pivot, characterised in that it comprises a spring (15) stressed between the pivot and the connecting rod and arranged so as to press one of the plane faces of the pivot against one of the plane faces of the connecting rod.
