Locking device arrangement for a rotating bladed stage

A locking device arrangement for a rotating bladed stage, comprising:

• a first rotatable body formed to define a first slot and three slot sections, one of the slot sections including a second slot and two third slots in communication with the first slot and the other slot sections including third slots in communication with the first slot;
• a plurality of second bodies arrayed in the first slot by way of installation via the second slot;
• and
• a plurality of third bodies respectively disposed within the third slots,
• the three slot sections being separated from one another with angular offsets such that the first body is mass balanced substantially evenly about a desired center of rotation with the plurality of third bodies disposed within the third slots and to reduce accumulation of flowpath gaps.

A method of assembling a locking device arrangement for a rotating bladed stage, comprising:

• forming a first rotatable body to define a first slot and three slot sections, one of the slot sections including a second slot and two third slots in communication with the first slot and the other slot sections including third slots in communication with the first slot;
• installing a plurality of second bodies in the first slot via the second slot;
• and
• installing a plurality of third bodies within each third slot,
• the forming comprising separating the three slot sections from one another with angular offsets such that rotation of the first body is mass balanced substantially evenly about a desired center of rotation with the plurality of the third bodies installed within each third slot and to reduce accumulation of flowpath gaps.
