FIELD: machine building.
SUBSTANCE: invention relates to machine building and may be used for the processing equipment, including weaving looms vibration isolation. Two-stage vibration isolator for unbalanced equipment, made in the form of a two-stage frame consisting of successively connected and identical frames: upper and lower resilient damping elements coaxially placed therein, respectively, made in the form of cylindrical helical springs, which turns are covered with a vibration damping material, for example, polyurethane. Upper and lower frames are made in the form of coaxially arranged truncated cone rigid shells: the upper and lower, at that, each of shells upper base is a connected to them rigid disk, in each of which the upper and lower resilient-damping elements, respectively, rest against by the upper ends, and each of the truncated cone shells lower base is made open and intended for installation of at least two inclined resilient elements, as well as at least two connected to the base vertical resilient elements. Inclined resilient elements are located in the truncated cone shells peripheral part. Vertical resilient elements are connected with the of the of the truncated cone lower shell lower end part by their upper ends, and by the lower ends is to the base, at that, the resilient elements are installed in planes with a shift of 90°.
EFFECT: increase in the vibration isolation effectiveness.
