VIBRATION ISOLATOR BY KOCHETOV WITH DRY FRICTION Russian patent published in 2018 - IPC F16F13/02 F16F15/08 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Vibration isolator resilient element, housing and dry friction damper. Housing is made as two opposite bushings fixing the spring by the external surface. Damper is made as three resilient lobes rigidly connected with bottom bushing. Lobes with force enclosing the external surface of the spring. Spring contains body made out of helical hollow steel tube. Additional resilient steel tube is installed inside the casing coaxially with a gap. In the gaps between tubes the tubular friction elements are arranged having higher thermal expansion coefficient in comparison with steel. Surfaces of the casing and the additional resilient steel tube touch the surfaces of the friction elements. Screw solid resilient pin is set coaxially to the casing. From the inside, vibration isolator tabs are covered with layer of copper based sintered friction material.

EFFECT: increased efficiency of vibration isolation in resonance mode is being achieved.
