Abstract
Aspects of the disclosure are directed to a sync ring assembly associated with an engine, comprising: a sync ring, and a clevis coupled to the sync ring, where the clevis includes a rib that resists a deflection of the sync ring assembly when the engine is operated, and where the clevis is made of titanium.
Claims15
A sync ring assembly for a gas turbine engine, comprising:
- a sync ring disposed about an axis, the sync ring having an outer circumferential surface;
- and
- a clevis having a first axial side, a second axial side opposite the first axial side, and an inner circumferential surface extending between the first axial side and the second axial side, the inner circumferential surface of the clevis coupled to outer circumferential surface of the sync ring, the clevis comprising a first plurality of projections at a first circumferential end of the clevis and a second plurality of projections at a second circumferential end of the clevis, opposite the first circumferential end, each projection of the first plurality of projections and the second plurality of projections circumferentially spaced apart from each other projection, the first plurality of projections and the second plurality of projections projecting outward from the inner circumferential surface of the clevis and defining a plurality of stand-offs,
- wherein the clevis includes a rib disposed along at least a portion of the first axial side of the clevis and extending outward from the inner circumferential surface of the clevis and wherein the rib extends circumferentially between and contacts a first projection of the first plurality of projections and a second projection of the second plurality of projections, and
- wherein the first plurality of projections couples the clevis to the sync ring.
