DAMPING DEVICE FOR EXTENSION AND TORSION VIBRATIONS Russian patent published in 2014 - IPC F16F3/10 F16F1/32 F16F1/40 

FIELD: machine building.

SUBSTANCE: device comprises a casing with a cylindrical hole, a stop member set on the casing, a stem with a thrust collar placed in the casing cavity and damping elements of two types. The damping elements are located in the casing cavity between the thrust collar and the stop member. The damping elements of the first type comprise disk springs. The damping elements of the second type comprise disks and gaskets set between them; at that the disks and gaskets are made from materials with different ability to absorb mechanical energy in the course of deformation and destruction under shock load.

EFFECT: improved damping characteristics in the wide range of frequencies and amplitudes.
