Abstract
A squeeze film damper bearing has an inner support ring capable of supporting a bearing portion; an outer support ring disposed on an outer periphery of the inner support ring; and a dissipation portion formed on at least one of the outer support ring and the inner support ring to dissipate vibration energy. A damper gap formed between an outer circumferential face of the inner support ring and an inner circumferential face of the outer support ring is filled with a viscous fluid.
Claims14
A squeeze film damper bearing comprising:
- an inner support ring capable of supporting a bearing portion;
- an outer support ring disposed on an outer periphery of the inner support ring, wherein the inner support ring is configured to be movable in the radial direction relative to the outer support ring;
- and
- a dissipation portion formed on at least one of the outer support ring and the inner support ring to dissipate vibration energy, wherein
- a damper gap formed between an outer circumferential face of the inner support ring and an inner circumferential face of the outer support ring is filled with a viscous fluid, and
- when the inner support ring vibrates relative to the outer support ring, the viscous fluid flows into the dissipation portion and the vibration energy is dissipated.
