TWO-STAGE CYLINDER-CONICAL 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, including weaving looms, vibration isolation. Two-stage cylinder-conical vibration isolator is made in the form of two-stage frame consisting of in-series connected and identical frames: the upper and the lower frames, with elastic-damping element coaxially placed therein, made in the form of cylindrical helical spring, which turns are covered with the vibration damping material, for example, polyurethane. Vibration-insulated object is fixed on the upper frame. Upper and lower frames are made in the form of coaxially arranged with the elastic-damping element rigid cylindrical shell, and the shell in the form of truncated cone, coaxially and axially symmetrically attached to the cylindrical shell upper part, made in the form of inverted cup with hard bottom. Truncated cone shell lower base is made open and intended for installation of correspondingly resting on the struts at least two inclined elastic elements, connected to the lower frame base. On the lower frame base a ring with vibration damping material is fixed, for the resilient damping element lower end fixing, which upper end rests against the cylindrical shell rigid bottom through the vibration damping gasket. Correspondingly connected to the lower frame base and resting on the struts inclined elastic elements are made in the form of cylindrical helical springs.

EFFECT: increase in the vibration isolation effectiveness.
