Abstract
Abstract An improved rotor ring for use in an inertial energy storage rotor, the rotor being defined by a plurality of independent, concentric rotor rings rotatable about a vertical axis. The improved rotor ring includes a cylindrical body portion, fabricated from a fiber composite, and an unreinforced resinous face member attached to one or both of the opposing end faces of the ring. The resinous face member includes a number of radially oriented grooves which are adapted to accept clamps and other elements used to assemble and hold together the rotor rings.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
133 words
A rotor ring for use with an inertial energy storage wheel constructed from a plurality of such rotor rings held in relative concentric relation by a connecting means, the rotor ring comprising: an annular body member constructed from an elastomeric material reinforced with a multiplicity of generally circumferentially extending fibers, said body member including opposing end faces; and an annular face member constructed of a fiberless elastomeric material integrally bonded to at least one end face of said ring body in co-axial alignment therewith, the face member including a plurality of openings that extend over at least a portion of the radial width of the face member and open in a direction parallel to the longitudinal axis of and away from said rotor ring, said openings being adapted to receive said connecting means.
Claim 2
Dependent Claim
133 words
A rotor ring for use with an inertial energy storage wheel constructed from a plurality of such rotor rings held in relative concentric relation by a connecting means, the rotor ring comprising: an annular body member constructed from an elastomeric material reinforced with a multiplicity of generally circumferentially extending fibers, said body member including opposing end faces; and an annular face member constructed of a fiberless elastomeric material integrally bonded to at least one end face of said ring body in co-axial alignment therewith, the face member including a plurality of openings that extend over at least a portion of the radial width of the face member and open in a direction parallel to the longitudinal axis of and away from said rotor ring, said openings being adapted to receive said connecting means.
Claim 3
Dependent Claim
47 words
The rotor ring of claim 1, including a second annular face member of an unreinforced elastomeric material attached to the opposite face of said body member in co-axial alignment therewith, the second ring member including a plurality of axially aligned grooves adapted to receive the connecting means.
Claim 4
Dependent Claim
34 words
The rotor ring of claim 2, wherein each of the end faces of the body member includes a plurality of concentric channels formed in each one of the end faces of the body member.
Claim 5
Dependent Claim
128 words
A rotor ring for use in a multiring inertial energy storage wheel, the rotor ring comprising: a generally cylindrical body terminating in opposed end faces and constructed of a yieldingly deformable material, the body including a multiplicity of generally annular, circumferentially oriented reinforcing fibers embedded in the material for increasing the circumferential strength of the body; and means attached to at least one end face of the body and defining a plurality of openings that extend over at least a portion of the radial width of the body, the openings being disposed on the end face of the body and being formed to open in a direction parallel to a longitudinal axis of and away from the ring, the means being constructed of a fiberless yieldingly deformable material.
Claim 6
Dependent Claim
128 words
A rotor ring for use in a multiring inertial energy storage wheel, the rotor ring comprising: a generally cylindrical body terminating in opposed end faces and constructed of a yieldingly deformable material, the body including a multiplicity of generally annular, circumferentially oriented reinforcing fibers embedded in the material for increasing the circumferential strength of the body; and means attached to at least one end face of the body and defining a plurality of openings that extend over at least a portion of the radial width of the body, the openings being disposed on the end face of the body and being formed to open in a direction parallel to a longitudinal axis of and away from the ring, the means being constructed of a fiberless yieldingly deformable material.
Claim 7
Dependent Claim
32 words
The rotor ring of claim 4, wherein the means includes an annular member having a plurality of openings extending over at least a portion of the radial width of the annular member.
Claim 8
Dependent Claim
