In a one embodiment, a balance weight includes a base, a rotational axis extending from the base, and a circumference having opposite cam surfaces about the rotational axis. The opposite cam surfaces are at least partially angled toward one another in a direction away from the base along the rotational axis. The balance weight is designed to mount in a groove of a rotary component of a turbine engine.

Rotary machine balance weights

The control stage buckets for a steam turbine have airfoils which are hollowed out to form an interior cavity within the airfoil. The cavity opens through the radial inner platform of the bucket and terminates short of the tip of the bucket. The buckets are therefore of reduced weight. This reduced weight causes reduced creep damage in the axially extending dovetails along the rotor rim.
