Abstract:
A damper for damping the radial vibrations incidental to the blades of a turbine rotor, said damper being a generally Y-shaped member, said turbine rotor including a disk, a plurality of circumerentially spaced blades supported in said disk, said damper being made from a single piece and freely mounted in a radial slot formed in proximity to said disk, said slot defining a wall surface, a portion of said generally Y-shaped member bearing against said at least one blade of said blades, and one leg of said Y-shaped member bearing against said wall surface of said radial slot, wherein said portion radially bears against said blade adjacent to said disk when said rotor is rotating, said Y-shaped member having a center of gravity at a location that is offset from where said portion bears against said blade, wherein the vibrations exciting said blade in the radial direction are transmitted through said damper to said disk for creating a friction between said one leg of said Y-shaped member and said disk for attenuating said vibrations.
