The bush (18), designed to fit in a cavity (20) of a turbine ring (22), consists of a tubular body (24) with a conical collar (26, 28) at each end, positioned so that their identical conical surfaces, tapering at 30 - 60 degrees, face one another. The mean diameter of the collars is approximately the same as the distance between them. One of the collars is made in one piece with the bush, and the other is fixed on assembly. In a variant the bush can have an anti-rotation system in the shape of a fixed external cube that engages with a matching hole in the ring. |
