Abstract
Abstract A rotor structure having at least two radially extending rotor disks. The disks are adjacent to each other and have a knurled portion disposed on one of the disks. The disks are compressed, thereby embossing the knurled portion onto at least one of the disks to prevent relative rotational movement of the disks. Bolts are axially disposed through the disks to prevent axial movement of the disks.
