Problems solved by technology

However, further stiffening of the casing would only undesirably exacerbate the effect of a loose flywheel, as the flywheel could go into a self-accelerating natural frequency type of rotation mode and accelerate uncontrollably

Embodiment Construction

[0037] figure 1 A schematic perspective view of a three-lobed flywheel system 1 with a housing 2 and a disc-shaped or annular flywheel rotor 3 is shown, the housing comprising a base 4 and a housing wall 5 . The flywheel rotor is relatively large; it generates enormous forces and Unleash enormous energy.

[0038] Figure 2A and Figure 2B The embodiments are most similar in terms of the number of protrusions to figure 1 the embodiment. In this embodiment, three dampers 8 defining protrusions are arranged in such a way that they are equally or uniformly distributed around the flywheel rotor 3 . As long as the flywheel rotor is in Figure 2A In the state, everything is normal.

[0039] However, when the flywheel rotor 3 as in Figure 2B , the flywheel rotor will begin to roll along the inner surface of the housing wall 5 and may also begin to wobble, i.e., relative to the drawn Figure 2A and Figure 2B The plane swings up and down. The damper 8 defines a protrusion a...

Abstract

The present disclosure relates to a flywheel system, comprising a ring-shaped flywheel rotor, arranged on a rotation axis; and a substantially cylindrical casing, enveloping the flywheel rotor at least in a radial direction to contain the flywheel in case of a calamity. The flywheel system further exhibits the feature that the casing comprises and having at least one inward protruding bumper defining a variation from the circular shape in cross section of the casing wall surrounding the flywheel rotor. The casing wall may itself be circular and the bumper can define a deviation relative to thecircular shape thereof, to enhance deceleration of the flywheel rotor, if, in case of an accident or calamity, the flywheel rotor comes loose.

Description

technical field [0001] The invention relates to a flywheel system. Conventionally, a larger-sized flywheel system may include: a ring-shaped flywheel rotor arranged on a rotating shaft; and a substantially cylindrical housing that surrounds the flywheel at least in a radial direction rotor to accommodate the flywheel in case of disaster. Herein, the housing is used to restrain or confine the flywheel rotor in case of an emergency such as failure of the rotating shaft, bearings and / or components and parts assembled with the flywheel rotor. Background technique [0002] Conventionally, such housings include circular walls for retaining the flywheel rotor within the boundaries defined by the walls. In the event of such a contingency, such as a component failure, the flywheel rotor can stop spinning on its own and start rolling against the housing walls. In emergencies in which the flywheel rotor comes into contact with the housing wall following failure of a bearing or rotor...
