FIELD: machine building.SUBSTANCE: vibration isolator includes a base in the form of a round bottom with a stock rigidly fixed on it, and guide and elastic devices. Guide device is made in the form of a cylindrical sleeve coaxial to the stock and rigidly attached to the base. Elastic device is made in the form of a pack of flat annular springs fixed in the sleeve with its peripheral part by means of a spacer elastic sleeve and stiff supports, and with its central part made in the form of a hole coaxial to the stock, which are fixed on the stock through the spacer stiff sleeve. The stock has a hollow structure with an inner threaded hole in its lower part. The stock is connected to a threaded bar rigidly attached to the bottom through a stiff support and an elastic washer, for example a lockwasher. A pack of flat annular springs is made in the form of two elastic coaxially located rings, external and internal ones, which are rigidly attached to each other by means of at least two opposite located elastic plates with formation of curved cutouts made for example in the form of circular sectors.EFFECT: improving reliability of a damper and vibration isolation efficiency.2 dwg |
