Abstract
Abstract A high energy storage flywheel is described, consisting of a rim of anisotropic material such as music wire. A divided hub has coaxially placed portions which are rotationally displaceable with respect to each other and are intercoupled by resilient means. Distinct sets of spokes connect the respective hub portions to the rim. By this construction the tension of the spokes due to the expansion of the rim upon rotation of the wheel is compensated by the mutual rotational displacement of the hub portions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
71 words
A high energy storage flywheel comprising a rim of anisotropic material, a divided hub having coaxially positioned portions rotationally displaceable with respect to each other, resilient means intercoupling said portions and distinct sets of radial spokes interconnecting said rim with said portions whereby, upon rotation of said wheel, the tension in said spokes produced by the expansion of said rim is compensated by the mutual rotational displacement of said hub portions.
Claim 2
Dependent Claim
71 words
A high energy storage flywheel comprising a rim of anisotropic material, a divided hub having coaxially positioned portions rotationally displaceable with respect to each other, resilient means intercoupling said portions and distinct sets of radial spokes interconnecting said rim with said portions whereby, upon rotation of said wheel, the tension in said spokes produced by the expansion of said rim is compensated by the mutual rotational displacement of said hub portions.
Claim 3
Dependent Claim
95 words
In a high energy storage flywheel construction, the combination of a rim, two distinct sets of spokes attached to said rim, a hub divided into coaxially disposed portions comprising a central portion terminating at each end in a hub flange, a pair of hub disks, each facing one of said flanges, respectively, one set of said spokes being attached to said flanges and the other set of said spokes being attached to said disks, a shaft extending into said hub and being keyed to one of said portions and resilient means interconnecting said hub portions.
Claim 4
Dependent Claim
95 words
In a high energy storage flywheel construction, the combination of a rim, two distinct sets of spokes attached to said rim, a hub divided into coaxially disposed portions comprising a central portion terminating at each end in a hub flange, a pair of hub disks, each facing one of said flanges, respectively, one set of said spokes being attached to said flanges and the other set of said spokes being attached to said disks, a shaft extending into said hub and being keyed to one of said portions and resilient means interconnecting said hub portions.
Claim 5
Dependent Claim
42 words
The combination in accordance with claim 2 wherein said shaft is keyed to said hub disks and said resilient means comprise a pair of torsion springs attached at one end to said shaft and at the other end to said flanges, respectively.
Claim 6
Dependent Claim
35 words
The combination in accordance with claim 2 wherein said shaft is keyed to said central portion and said resilient means comprise a plurality of coaxially disposed spring rods interconnecting said flanges and said hub disks.
Claim 7
Dependent Claim
46 words
The combination in accordance with claim 2 wherein said sets of spokes comprise steel rods, one of which is forward leaning and the other backward leaning, said backward leaning spokes being attached to said flanges and said forward leaning spokes being attached to said hub disks.
Claim 8
Dependent Claim
30 words
The combination in accordance with claim 2 wherein said rim consists of a support and layers of a continuous high tensile strength filamentary material, such as music wire, wound thereon.
