Abstract
The present invention relates to a rotor assembly. The rotor assembly includes a rotor having rotor holes disposed about an axis. Bushings are disposed within the rotor holes in order to protect the rotor holes from compression impact deformation. Each bushing includes an internal slot that permits the rotor to radially expand and contract due to changes in the temperature of the rotor. A hub having pin holes that align with the rotor holes is held to the rotor by drive pins disposed within the pin holes and the bushings. A bolt is placed into the drive pin and tightened to fix the hub to the rotor in the axial and circumferential directions. Other features are disclosed.
