Japanese Patent JP2014040829

A

To provide a turbine bucket including an integral rotation controlling feature.

In one embodiment, a turbine bucket comprises: a blade section having an inner radial end and an outer radial end; an integral cover section connected to the outer radial end of the blade section; and a base section for engaging a rotor body, the base section connected to the inner radial end. The base section comprises: a central body; a set of tongues extending axially from the central body; a set of flanges radially inboard of the set of tongues and extending axially from the central body; and an integral rotation controlling feature extending from the central body, where the rotation controlling feature engages a radial opening in the rotor body. The integral rotation controlling feature is sized to limit rotation of the base section when the turbine bucket is engaged with the rotor body.
