DISK-SHAPED RESILIENT ELEMENT BY KOCHETOV Russian patent published in 2014 - IPC F16F3/02 F16F7/08 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. A disk-shaped resilient element comprises a body in which two resilient elements: a lower one and an upper one - are oppositely installed. Each of the disk-shaped resilient elements comprises two flat resilient coaxially set rings: of smaller diameter and of greater diameter. The rings are coupled to each other by three resilient flat plates inclined to the rings' axis. Each of the rings of smaller diameter is coupled with the respective cover by screws. A resilient element in the form of a cylindrical coil spring is mounted between the covers. Each of the rings of greater diameter is coupled with the respective lower and upper parts of the body. The lower body part consists of a base made as a disk with annular inner groove. The lower disk-shaped resilient element's lower resilient ring of greater diameter is set in the disk groove. A ring from friction material is attached to the lower part of the lower ring to provide for dry friction ensuring the required shock absorption in the system.

EFFECT: increased efficiency of vibration isolation in resonance mode.
