The invention relates to mechanical engineering and can be used to protect the process equipment from the effects of vibration.

The closest technical solution to the declared object is vibration absorber spring-containing base, stand, elastic spring elements type and reference nodes, as the USSR №1590759, F 16 F 7/08 from 29.12.88.

Lack of work of the known device is relatively low effectiveness of vibration isolation with changing mass vibroisolating object.

The aim of the invention is to increase the effectiveness of vibration isolation by providing ravnochestnosti.

This is achieved in that in the vibration damper leaf containing the base, the rack, the elastic element is a spring type and the reference node, the elastic spring element the type of the variable cross-section in mutually perpendicular planes, and the cross-sectional area increases from the reference node, which is attached vibrotherapy object to the rack, which is firmly fixed to another end of the elastic element.

The drawing shows a General view of the vibration damper spring runecasting.

Vibration absorber spring revocatory comprises a base 1, rack 2, the elastic element is a spring type 3 and the reference node 4. Elastic spring element the type of the variable cross-section in mutually PE pendicular planes, moreover, the cross-sectional area increases from the reference node 4, which is attached vibrotherapy object to the rack 2, which is firmly fixed to another end of the elastic element. The sides of the elastic element is limited by straight lines running at an acute angle to the axis of the elastic element. It is possible that the sides of the elastic element is limited by curves of the second order or "n"-th order, which are made so that they provide a reduction of the cross section of the elastic element in the direction of the reference node, which is attached vibrotherapy object (for example, a paraboloid, a hyperboloid, or a body of rotation formed by the lines "n"-th order). The reference node 4 is made in the form of a sleeve 5 whose inner surface is in contact with the free end of the elastic element 3. Movement of the sleeve 4 is limited by the stop 6 in the form of a pin or lock washer.

Vibration absorber spring revocatory works as follows.

When forced oscillations vibroisolating object (not shown) occurs dynamic response, which is extinguished by the elastic element 3 spring type, which is also the guiding device in the vertical and horizontal displacements vibroisolating object. Ravnochestnosti dynamic properties of insulator is provided vypolneniem spring element variables section in mutually perpendicular planes, moreover, the cross-sectional area increases from the reference node 4, which is attached vibrotherapy object to the rack 1, which is firmly fixed to another end of the elastic element.

Vibration absorber spring revocatory containing base, stand, elastic spring-type element and the reference node, characterized in that the elastic spring element the type of the variable cross-section in mutually perpendicular planes, and the cross-sectional area increases from the reference node, which is attached vibrotherapy object to the rack, which is firmly fixed to another end of the elastic element.
