DYNAMIC DAMPER Russian patent published in 2005 - IPC

FIELD: machine building, in particular, pendulum dampers of vibrations of machine-building equipment.

SUBSTANCE: the dynamic damper of vibrations has a lever connected to the vibrating object and a hollow body, fastened on the lever and filled with working environment. The body end faces are made in the form of membranes engageable at an excess of the threshold amplitudes with restricting stops providing vibrating-impact suppression of vibrations. An insert is fixed in the body seprating the space with the working environment into two chambers with a channel connecting the mentioned two chambers. Liquid is used as the working environment.

EFFECT: enhanced efficiency of vibration damping due to the use of combination damping lying in the use of pendulum vibrating-impact suppression at large amplitudes with employment of a hydraulic motion transducer, which makes it possible to reduce the structural parameters of the pendulum damper.
