SPRING DRY FRICTION DAMPER Russian patent published in 2018 - IPC F16F3/04 F16F7/04 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Spring damper of dry friction contains lower and upper bearing plates. Coaxially and concentrically outer, with the right angle of elevation of the coils, and internal with the left angle of elevation of the coils springs are mounted. Bottom support plate is the base. Bottom disc is rigidly linked with the top flange of the internal spring. Top disc is rigidly linked with the upper support plate. Upper disc of the dry friction damper is made of steel. Lower disc is made of friction material made from a composition. Contact surfaces of the lower and upper discs of the dry friction damper are made equidistant and congruent.

EFFECT: enabling increase in the vibration isolation efficiency in resonance mode.
