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 conical vibration isolator is made in the form of a two-stage frame consisting of successively connected and identical frames, the upper and lower, 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. Upper and lower frames are made in the form of coaxially arranged truncated cone rigid shells: the upper and lower. Each of 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 to the base. Elastic elements are installed in planes with the shift by 90°, and the upper frame obliquely arranged elastic elements, as well as the lower frame vertical elastic elements are made in the form of cylindrical helical springs.
EFFECT: increase in the vibration isolation effectiveness.
