ABSTRACT:
Means for securing a member, such as a blade retainer, to a structure, such as a disc. An annular, preferably split, retaining ring is disposed in a recess of the disc and is shaped to receive a part of the blade retainer which is also disposed within the recess thereby securing the blade retainer to the disc.
A method of securing the blade retainer to the disc is also provided and includes the steps of inserting the retaining ring into the recess and compressing the ring, inserting a part of the blade retainer into the recess and deflecting it axially, and releasing the retaining ring from compression and the blade retainer from deflection.
