FIELD: machine building.SUBSTANCE: invention relates to machine building. Vibration isolator includes a housing in form of a sleeve with a hole, resting on upper end of elastic element from elastomer, for example rubber. Bottom part of casing contains rings with collar for connection with elastomer. For attachment of upper part of vibration isolator bottom is support ring. Lower part of vibration isolator contains base and cover, between which there is a flexible element made from rubber. Cover is connected by screws to upper part through an additional vibration damping layer. In resilient element from rubber dry friction element is arranged in form of piston connected with cover and male sleeve rigidly attached to base. Between lower end of piston and bottom sleeve there is a mesh elastic element. In hole of sleeve resting on upper end of elastic element from elastomer, an additional elastic damping element of cylindrical shape, made from polyurethane. Upper end of additional damping element is fixed in sleeve, and lower thrusts against additional vibration damping layer.EFFECT: improved efficiency in resonant mode of vibration isolation.1 cl, 1 dwg |
