<p>A flywheel (10) for high angular momentum devices such as gyroscopes and the like, including a drive member (12) having a splined outer portion (16), and a spacer member (20) having a splined inner portion (22) positioned around the drive member (12). The splined inner portion (22) of the spacer member (20) is in cooperating relationship with the splined outer portion (16) of the drive member (12), thereby enabling the drive member (12) to impart a rotational drive force to the spacer member (20). The splined connection between the drive member (12) and the spacer member (20) enables the spacer member (20) to float outwardly from the drive member (12) under centrifugal loading. The flywheel (10) further includes an inertia ring (24) positioned around the spacer member (20) for providing the desired inertia mass for the flywheel (10). The outward movement of the spacer member (20) under centrifugal loading results in its compression against the surrounding inertia ring (24) to reduce radial tension forces in the flywheel (10) when rotated. A method of manufacturing the flywheel (10) is also provided which places the spacer member (20) in a state of compression.</p> |
