Elastomeric member for energy storage device

Patent ·
OSTI ID:6492797

An energy storage device is disclosed consisting of a stretched elongated elastomeric member, disposed within a tubular housing, which elastomeric member is adapted to be torsionally stressed to store energy. The elastomeric member is configured in the relaxed state with a uniform diameter body section, transition end sections, and is attached to rigid end piece assemblies of a lesser diameter. The profile and deflection characteristic of the transition sections are such that upon stretching of the member, a substantially uniform diameter assembly results to minimize the required volume of the surrounding housing. During manufacture, woven wire mesh sleeves are forced against a forming surface and bonded to the associated transition section to provide the correct profile and helix angle. Each sleeve contracts with the contraction of the associated transition section to maintain the bond therebetween.
