Inter-vane platform with flexible securing pins and variable shear stresses for a support disk for the vanes of a turbine engine

摘要

An inter-vane platform (3) for a vane support disk (1) of a fan of a turbine engine, comprising a deflecting part (4) includes a lower face (5) provided with at least one first securing foot (6), provided with at least one aperture (7) for the passage of a securing pin (8) intended to connect it to a second securing foot (12) of the support disk (1), between two adjacent vanes. The securing pin (8) includes a rod (17) provided with a first threaded part (18) having a first diameter (D1) chosen and intended to accommodate a nut (22) intended for the connection, and a second part (19) including a first sub-part (20) extending the first sub-part (18), having a second diameter (D2) greater than the first diameter (D1) and intended to be interlaced between the first (6) and second (12) securing feet, and a second sub-part (21) extending the first sub-part (20) and having a third diameter (D3) smaller than said second diameter (D2) in such a way as to be able to pass through the aperture (7) of the first securing foot (6).
