FIELD: machine building.SUBSTANCE: spring comprises a casing made from a spiral hollow resilient steel tube. An additional resilient steel tube is installed inside the casing coaxially with a gap. A friction element is placed in the gap between the tubes and is made from polyethylene having higher thermal expansion coefficient as compared to steel. The surfaces of the casing and the additional resilient steel tube touch the surfaces of the friction elements. A screw solid resilient pin is set coaxially to the casing. The Friction elements are tubular, in the form of granulated fill from polyethylene with vibration damping material granules included.EFFECT: increased efficiency of vibration isolation in a resonance mode.2 cl, 1 dwg |
