TORSIONAL KEYED SLEEVE FLUID DAMPER |
| 摘要 |
A damper assembly for a rotating shaft includes an inner sleeve and an outer sleeve extending along a longitudinal axis. The outer sleeve is disposed radially outward of the inner sleeve relative to the longitudinal axis. The inner sleeve is rotatable relative to the outer sleeve about the longitudinal axis. A damping fluid is disposed between the inner sleeve and the outer sleeve. At least one of the inner sleeve and the outer sleeve includes a damping feature, such as a fin, vein, channel, etc., which engages the damping fluid. The engagement between the damping feature and the damping fluid resists rotation of the inner sleeve relative to the outer sleeve to attenuate torsional vibration disturbances transmitted to the inner sleeve. |

1. A damper assembly for a rotating shaft, the damper assembly comprising:
an inner sleeve extending along a longitudinal axis; an outer sleeve extending along the longitudinal axis and disposed radially outward of the inner sleeve relative to the longitudinal axis, wherein the inner sleeve is rotatable relative to the outer sleeve about the longitudinal axis; and a damping fluid disposed between the inner sleeve and the outer sleeve; wherein at least one of the inner sleeve and the outer sleeve includes a damping feature engaging the damping fluid, wherein the engagement between the damping feature and the damping fluid resists rotation of the inner sleeve relative to the outer sleeve to attenuate torsional vibration disturbances transmitted to the inner sleeve. |
