Abstract

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.
