FIELD: machine building.SUBSTANCE: invention relates to machine building. Vibration dampening spring comprises a casing made from a spiral hollow resilient 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 tubular and made in the form of granulated fill from sintered friction copper-based material, which contains zinc, iron, lead, graphite, vermiculite, copper, chromium, antimony and silicon.EFFECT: improved efficiency in resonant mode of vibration isolation.1 cl, 1 dwg |
