Ring assembly for inertial energy storage rotor
Patent
·
OSTI ID:6489590
The invention discloses an inertial energy storage rotor defined by a plurality of independent, concentric rotor ring assemblies rotatable about a vertical axis. Each assembly has at least two co-axial rings and a plurality of circumferentially spaced apart, U-shaped clamps which secure the rings of the assembly to each other. Opposing end faces of the rings include a plurality of circumferentially spaced apart, opposing grooves which define between them radially oriented apertures. The clamps include radially inwardly and radially outwardly extending plugs which are shaped complementarily to the configuration of the holes in the adjacent inner and outer ring assemblies and which concentrically interconnect adjacent ring assemblies. The plug extending radially inward and disposed in the hole of the ring assembly inward of the clamp has a tapered configuration in a radial plane of the ring assembly. The taper is chosen so that axial movements of the U-shaped connector and its plugs due to the relatively larger dilation of the outer ring assembly during high speed rotation of the rotor result in a continued engagement between side walls of the inwardly oriented plug and the corresponding sides of the hole.
