FIELD: machine building.SUBSTANCE: invention relates to machine building. Vibration isolator comprises a housing and resilient elements. Housing is designed as a jointed lever mechanism which consists of a horizontal arm and vertical rods. One end of levers is rigidly connected with lids resting on resilient elements and other - are pivotally connected to rods. Traction is pivotally connected with a horizontal platform on which technological equipment is mounted. Ends of resilient members are in contact with resilient washers mounted between base and lid. Resilient members are designed as a damper with integrated springs. Spring is a screw cylindrical one and consists of two parts with on-coming ends. First spring part is fitted with turns of rectangular section and rounded edges and second part is hollow. On-coming end of first part is located in cavity of second part. Gaps of the segment profile of contacting spring parts are filled by antifriction grease. Sealing gasket is mounted at end of second spring part to prevent grease leakage. First part of helical spring encloses tube from damping material, for example polyurethane.EFFECT: higher efficiency of vibration isolation in resonance mode.1 cl, 2 dwg |
