FIELD: machine building.SUBSTANCE: vibration isolator consists of base, elastic elements and bearing assemblies. The elastic elements are designed as a package of top and bottom elastic elements of arch type facing to each other. Each package is designed as a set of flat springs alternating in mutually perpendicular directions. Every flat spring consists of a horizontal flange and two lateral flanges bent at the angle 135° to the horizontal flange and fitted with bearing sections at the ends. The damping element of the vibration isolator is a compound one and consists of a friction part and an elastic part. The friction part is made as bushes with flanges at the ends and a section of a rope wound on the bushes in a closed loop. The bushes are coupled with the resilient elements by rivets. The elastic part is made as an elastodamping ring embracing the rope section from outside. The ring material is elastomer, e.g. rubber, polyurethane or combined material, such as rubber-cord casing. The elastic part of the damping element is performed in a static state with pre-load onto a friction part.EFFECT: higher vibration isolation efficiency.2 cl, 2 dwg |
