DISC ARRANGEMENT, RETENTION SYSTEM, AND METHOD OF RETAINING TWO SEPARATE ROTATING MEMBERS OF A GAS TURBINE MACHINE

摘要

A gas turbine engine disk split retainer ring system is provided and includes an apparatus and method for retaining a split ring in relation to a turbine cover plate or disk. Pegs are used to capture and retain a split retainer ring of the gas turbine rotor in relation to the cover plate. An anti-rotation peg has a radially oriented tab for engaging the split ring so as to control the rotation of the ring. The system may be used to balance the operating condition of a turbo machine.
