Embodiment 1

[0032] refer to figure 1 and figure 2 , a high-strength fiber flywheel, the high-strength fiber flywheel includes a flywheel base 1 and a high-strength fiber wire 2, the flywheel base 1 includes a wheel rim 1a, a spoke 1b and a hub 1c, and the high-strength fiber wire 2 wound on the rim 1a.

[0033] The high-strength fiber thread 2 wound on the rim 1a is a single fiber thread, and the high-strength fiber thread 2 is wound on the rim 1a layer by layer.

[0034] During the above winding process, the high-strength fiber strands 2 are coated with a binder to facilitate the consolidation and forming between the high-strength fiber strands.

[0035] The single high-strength fiber wire 2 may be a single multi-strand wire composed of multiple thinner high-strength fiber wires.

[0036] The high-strength fiber strands in this embodiment are high-strength carbon fiber strands.

Embodiment 2

[0038] refer to Figure 1 to Figure 7 , a method for manufacturing a high-strength fiber flywheel, the specific steps include,

[0039] (1) The high-strength fiber wire 2 is tightly and evenly layered and wound on the outer surface of the rim 1a along the circumferential direction of the rim 1a, and when the required number of winding layers is reached, the circumferential The high-strength fiber line 2 is bent and turned at T located on a certain side edge of the flywheel,

[0040] (2) Wind the high-strength fiber line 2 along the side of the flywheel to the inner surface of the rim 1a, pass through the gap between the spokes 1b, and wind the high-strength fiber line from the other side of the flywheel to the circumferential high-strength fiber line of the flywheel along the side 2, reaching the T of the front segment high-strength fiber line when going around the whole circle,

[0041] (3) Press the current section of the high-strength fiber line 2 on the inside of the ben...

Abstract

The invention relates to a high-strength fiber flywheel, which comprises a flywheel matrix and a high-strength fiber line. The flywheel matrix comprises a rim, spokes and a hub, and the high-strength fiber line is entwined on the hub. The invention also provides a manufacturing method of the high-strength fiber flywheel. The high-strength fiber flywheel can effectively satisfy the needs of ultra-high-speed rotation of the flywheel.

Description

technical field [0001] The invention belongs to a flywheel of a flywheel battery and a manufacturing method thereof. Background technique [0002] How to efficiently store electrical energy has always been a major concern of human society. The current commercialized power storage devices are almost all kinds of chemical storage batteries, but they have been unable to get rid of the inherent disadvantages of chemical batteries: low energy density, large pollution, short life and other defects. Therefore, in recent years, physical power storage devices have received extensive attention from the scientific and technological community, among which flywheel batteries (also known as flywheel energy storage devices) have shown huge advantages: high specific energy, large specific power, small size, fast charging (in minutes meter, while the chemical battery is measured in hours), long life, no waste gas pollution and so on. [0003] Over the past ten years, foreign research insti...
