ABSTRACT:
A rotor disk assembly having a plurality of rotor disks secured together by annular projections with screw threads thereon for easy assembly and disassembly. The annular projections include a plurality of spring biased pins that push against an opposing annular projection due to centrifugal forces during rotation of the rotor disks at such a force as to hold the rotor disks against loosening from vibrations. The spring biased pins have a low enough spring constant that the pins are disengaged when enough torque is applied to unscrew the rotor disk from one another.
