SU1350405A1 - Vibration isolator - Google Patents

Abstract

The invention relates to the field of mechanical engineering, in particular to means of protection against vibration. The aim of the invention is to improve the efficiency of vibration insulation by increasing the degree of damping, which is achieved by pulling out the elastic elements in the form of rolled up into multi-layered rubber strips of wires interacting with the elastic ring of rubber-cord material that engages. the latter with an elastic ring allows one to obtain a hysteresis characteristic of the device and, as a result, effective damping of oscillations. 4 yl.

Vibroinsulator SOD Nrysit SOOSNO pSC

the laid-on units 1 and 2 of attachment to the object 3 and the base 4 elements, made in the form of rolled-in and multi-layer ring 5 and rubber-like wire segments 6 and oriented relative to the plane of the vibration insulator 0-0 passing through the axis and the elastic ring 7, are made of rubber-cord material having holes 8c, the axis of which the pair is 0-0 to the axis and through which the skip; elastic elements 5. Elastic elements 5 are attached to the nodes 1 and 2 of the fastening close to each other with the pads 9 and screws 10.

Vibroizol tor works sledtaoschi .; in a way.

Under the action of vibration and shock, the elastic elements 5 deform the cjj and unclench the ring 7s, which leads to effect 504052.

effective damping of vibrations and shocks due to the nonlinear elastic characteristic with a wide hysteresis loop due to the contact interaction of the wire 6 between itself and the rubber sheath; as well as the last with a ring 7.
