DAMPER FOR VERTICAL ROTOR Russian patent published in 2010 - IPC F16F9/10 

FIELD: machine building.

SUBSTANCE: damper comprises case with damping fluid. The first damping element is arranged in the form of cylinder with step-bearing for rotor support alignment springs in upper part, hingedly resting in lower part of case. The second damping element is arranged in the form of cylinder of stepped shape, lower part of which has larger diametre and is placed into case cavity with damping fluid, and in upper part of lower diametre there is a sliding bearing, which embraces rotor axle with a gap. Impact element is freely installed at one side of disk part of the second damping element with the feature of parallel displacement relative to it and its collision to vertical surface.

EFFECT: invention provides for reliable overcoming of bend critical frequencies by rotor without higher power inputs.
