Rotor with stress relief

摘要: The present invention provides a mechanism for bolting rotor to hub without introducing excessive radial stress around the bolt holes when is operating at high speed. (1) has slot cut (35) through its center eliminate perpendicular and thereby avoid problems of cracking otherwise weak section. mounting bolts (501) are necked down not threaded surface hub. into (501A) substantial distance from top (503) so that they can flex move out relative (32). interface lubricated facilitate motion rotor.
