ABSTRACT:
Pivoting vane internal extremity bearing (1) whose internal extremities are connected by a linking ring (12). The bearing elements (18) connecting the internal extremity pivots (10) to the ring (12) are composed of a bush (19) prolonged by bearing necks (20) with a spin axis (X') parallel to that of the ring (12). The forces undergone by the vanes, which transversally move the pivots (10), do not cause any wear of the bush (19), but a rotation of the latter around the axis (X'). Application for turbine aero engine stator vanes.
