Device for controlling a variable-angle vane via a pinch connection
Реферат: A device for controlling a variable-angle vane for a stator of a turbomachine compressor has a link (20), connection means forming a hinge between a first end of the link (20a) and a control ring (4) and fixing means (12) for fixing a second end of the link (20b) on a pivot (30) of a vane (2) to be controlled. The device comprises a clamping cap (40) applied against the second end (20b) of the link (20) and subjected to an axial clamping force under the effect of fixing means (12). The clamping cap presents a radial passage (48) having at least one inside face (48a, 48b) which is inclined relative to a longitudinal midplane (P) of said passage and which is for co-operating with a corresponding inclined side face of said second end of the link to act transversely relative to a longitudinal midplane (P) of the link to lock the second end of the link in rotation without slack on the pivot (30).
