Abstract (en)
[origin: WO2011151596A1] The invention relates to a device for preventing the rotation of a segment (80) of nozzle guide vanes assembly in the form of an annulus sector housed inside an annular casing (10) of a turbo machine with the interposing of a heat shield sheet (30) between the internal wall of the casing and the external wall of the segment (80) of nozzle guide vanes assembly, comprising a rotation-proofing peg (120) fitted both into a notch formed in the segment (80) of nozzle guide vanes assembly and in a housing formed in the casing, the heat shield sheet (30) comprising a tab resting against the rotation- proofing peg (120). The device is characterized in that it comprises the arranging of a surface portion (122c) radially between the tab and said internal wall of the casing, forming an end stop in the event of a possible radial movement of the heat shield sheet while the turbo machine is in operation. The invention also relates to the rotation-proofing peg used.
