Abstract
A retainer ring clamps, for example, a turbine cooling plate to a rotatable turbine disc. The retainer ring has a wedge-shaped channel that engages annular flanges on the cooling plate and the disc. The wedge-shaped channel converts radial forces on the ring to axial clamping forces which secure the cooling plate to the disc. Special tooling is not required to assemble the retainer ring to the cooling plate and turbine disc, and preloading of the cooling plate against the disc is not necessary. An angled or slanted gap in the ring eases assembly and disassembly of the retainer ring onto the annular flanges of the cooling plate and turbine disc and ensures that axial and radial movement of the retainer ring is required for disassembly of the ring from the flanges.
