TWO-STAGE CYLINDRICAL VIBRATION ISOLATOR Russian patent published in 2018 - IPC F16F15/06 F16F15/08 F16F3/10 F16F9/30 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building and may be used for the processing equipment vibration isolation, including weaving looms. Two-stage cylindrical vibration isolator is made in the form of two-stage frame, consisting of in-series connected and identical frames, the upper and lower frames, with upper and lower resilient damping elements coaxially placed therein, respectively, made in the form of cylindrical helical springs, which turns are covered with the vibration damping material, for example, polyurethane. On the upper frame, on the platform, a vibration-insulated object is fixed. Upper and lower frames are made in the form of the truncated cone coaxially arranged with a gap rigid cylindrical shells: the upper and lower ones, which upper ends are rigidly connected to the disks, respectively. Upper and lower resilient damping elements upper ends are fixed on the discs inner surface. Upper resilient damping element lower end is fixed to the lower frame disk outer surface, and the lower resilient damping element lower end is fixed on the base. Cylindrical shells peripheral parts are connected by at least two horizontal elastic elements, made of the material with adhesive and vibration damping properties, for example, polyurethane, and the vibration isolator lower cylindrical shell is connected to the base by means of vertical elastic elements, made in the form of cylindrical helical springs.

EFFECT: increase in the vibration isolation effectiveness.
