Abstract
A bearing and flywheel system can include a first bearing portion having an opening of a first dimension there through and a central longitudinal axis, a second bearing portion having a second dimension, the second dimension being smaller than the first dimension, and a flywheel coupled to the second bearing portion. The bearing portions can include high-temperature superconductor(s) and/or magnets. The second bearing portion can be disposed at least partially within the opening through the first bearing portion. A gap can exist between an outer surface of the second bearing portion and an inner surface of the first bearing portion. The second bearing portion can be configured to rotate relative to the first bearing portion.
Claims21
A system, comprising:
- a first bearing portion having an opening there through, a central longitudinal axis and an inner surface, the opening having a first dimension;
- a second bearing portion having an outside second dimension and an outer surface, the second dimension being smaller than the first dimension;
- and
- a flywheel coupled to the second bearing portion;
- wherein one of the first and second bearing portions includes a first magnet;
- wherein another of the first and second bearing portions is at least partially composed of a second magnet and includes a third magnet;
- wherein the second bearing portion is disposed at least partially within the opening through the first bearing portion and wherein a gap exists between the outer surface of the second bearing portion and the inner surface of the first bearing portion;
- and
- wherein the second bearing portion is configured to rotate about the central longitudinal axis of the first bearing portion relative to the first bearing portion;
- and further comprising a fourth magnet and a fifth magnet;
- wherein the fourth magnet is coupled to the bearing portion that includes the third magnet;
- wherein the fifth magnet is coupled to the bearing portion that includes the first magnet;
- and
- wherein the fourth magnet and the fifth magnet are configured to repel one another.
