FIELD: machine building.SUBSTANCE: vibration isolator comprises body, including base with cover and arranged in it package of series-connected plate-like resilient elements, inner surface of which interacts with bushing. One end of sleeve is rigidly fixed in base, and other end interacts with internal surface of cover, made in form of inverted barrel. End part of the cover interacts with dish-shaped elastic elements. Between end of bushing and bottom cover there is gap. In cavity formed by cover and sleeve, there is additional flexible element made in form of spring with built-in damper. 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 segment profile of contacting spring parts are filled by antifriction grease. Sealing gasket is mounted at the end of the second spring part to prevent grease leakage. First part of the screw spring is embraced by a tube of damping material, for example, polyurethane.EFFECT: higher efficiency of vibration isolation.1 cl, 2 dwg |
