FLYWHEEL ENERGY ACCUMULATOR Russian patent published in 2017 - IPC F16F15/315 

FIELD: machine engineering.

SUBSTANCE: flywheel energy accumulator contains a shaft, rolling bearings and two flywheels. Conical bushings are mounted on outer surface of the shaft between the rolling bearings for axial movement and are spring-loaded relative to each other. The flywheels are provided with hubs whose inner surface faces outer conical surfaces. Angle of convergence of cones of said conical surfaces is larger than the angle of self-braking. Rods are placed in openings of the hubs with possibility for tightening the hubs. Flanges are secured on the shaft between the rolling bearings.

EFFECT: increase of rotation operating frequency and reliability.
