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 vibration isolator for unbalanced equipment is made in the form of two-stage frame, consisting of in-series 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 the truncated cone coaxially arranged rigid shells: the upper and lower ones. Each of the shells upper base is the rigid disk connected thereto, in each of which the upper and lower resilient damping elements, respectively, rest against by the upper ends. 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 to the truncated cone lower shell lower end part by their upper ends, and by the lower ends is with the base, at that, the resilient elements are installed in planes, with shift by 90°. Obliquely arranged upper frame resilient elements, as well as the lower frame vertical resilient elements are made in the form of cylindrical helical springs.
EFFECT: increase in the vibration isolation effectiveness.
