High speed conical flywheel system
View Patent ↗A flywheel apparatus has a motor, a drive shaft connected to the motor, an upper conical section affixed to the drive shaft, and a lower conical section affixed to the drive shaft opposite said upper conical section. The upper conical section and lower conical section each have a plurality of layers, including a hollow core positioned adjacent the drive shaft, and alternating layers of tempered rings and non-tempered rings arranged outwardly of the hollow core. The alternating layers of tempered rings and non-tempered rings are joined with a elastomeric adhesive. The plurality of layers further include a hollow cavity positioned outwardly of the alternating layers, and a rim positioned outwardly of said hollow cavity. The hollow cavity can be filled with a fluid such as water, mercury-based fluids, oil-based fluids, or mixtures thereof.
