Abstract
Official abstract text for this publication.
A spoke locking arrangement comprising a washer seated in a seat defined in a structural ring of a gas turbine engine, the washer having a portion thereof plastically deformed into an anti-rotation notch defined in the structural ring, thereby locking the washer against rotation in the seat, the washer further comprising a set of holes for receiving corresponding bolts, and wherein the washer further has at least one anti-rotation tab at each hole, the anti-rotation tabs being deformable in engagement with the bolts to individually lock the same against rotation.
First claim
Opening claim text (preview).
The invention claimed is: 1. A gas turbine engine comprising a plurality of structural spokes supporting a bearing housing within a structural case, each structural spoke being mounted to a first surface of the structural case, a washer seated in a seat defined in a second surface of the structural case opposite to the first surface thereof, the washer having a portion thereof plastically deformed in an anti-rotation notch defined in the structural case, the washer further having a…
