VIBRATION ISOLATOR BY KOCHETOV WITH DRY FRICTION Russian patent published in 2016 - 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. Cylindrical helical spring contains body made out of helical hollow steel tube. Additional resilient steel tube is installed inside the casing coaxially with a gap. Friction element is placed in the gap between the tubes having higher thermal expansion coefficient as compared to 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. Friction element is made combined, e.g. from polyethylene with inclusions of vibration dampening material granules, or in form of granulated backfill from vibration damping material, from inside vibration isolator blades are coated with friction material layer.

EFFECT: improved efficiency in resonant mode of vibration isolation.
