SPRING-TYPE VIBROINSULATOR WITH NON-LINEAR DAMPING

摘要

FIELD: machine building.;SUBSTANCE: invention relates to machine building and can be used for vibration insulation of processing equipment. The proposed vibroinsulator comprises a casing, flexible and damping elements. The casing represents a plate with holes and flexible mounting elements attached to the plate lower surface. The cover that represents a reverse cup with a central hole is attached to the plate. The piston made from friction material interacts with the cover inner surface. The said piston is jointed to the receiver bushing aligned with aforesaid cover central hole. The piston is jointed to receiver bushing with the help of thread stud and top and bottom nut-jointed washers. At least, two flexible lock rings are arranged inside the piston and aligned with it. The piston is spring-loaded by the top conical spring relative to the cover and by bottom conical spring, relative to the plate. The larger bases of conical springs face the cover and the plate, respectively. The bottom conical spring is mounted on the plate via the annular elastic damper that houses the coaxial ring made from thread-waste-type wire.;EFFECT: higher efficiency of vibration insulation.;2 cl, 2 dwg
