ABSTRACT:
The present invention provides an improved sideplate of the type adhered to the side of a rotor disk for the retention of rotor blades and for blocking the leakage of working medium gases across the rotor disk. The elimination of retaining bolts and rivets is sought.
In one effective embodiment of the present invention, the sideplate is adhered to the disk at a bayonet type joint. The sideplate is elastically deformable to enable assembly of the sideplate onto the disk with abutting surfaces of the disk and sideplate in interference engagement at release. The side surface of the disk is tapered in cross section geometry to accommodate deformation of the sideplate.
