Abstract: A rotating machine includes a stationary member and a rotating member moveable relative to the stationary member. The rotating member includes at least one balancing member assembly receiving portion having a plurality of internal threads. The rotating machine also includes a balancing member assembly including first and second interlocking balancing members. The balancing member assembly also includes a plurality of external threads that are operatively connected to the internal threads of the balancing member assembly receiving portion. With this arrangement, the balancing member assembly provides a dynamic balance for the rotating member.

Abstract: A rotating machine includes a stationary component, a rotating component that is moveable relative to the stationary component, and a balancing member detachably mounted to the rotating component. The balancing member includes a self-locking device that selectively engages the rotating component when in a locked position and disengages the rotating component, to permit removal of the balancing member, when in an unlocked position. In this manner, the self-locking device prevents the balancing component from becoming loose during operation of the rotating machine without requiring staking the balancing component to the rotating component.
