KOCHETOV DISC-SHAPED RESILIENT ELEMENT WITH DRY FRICTION DAMPER Russian patent published in 2016 - IPC F16F3/02 F16F7/08 

FIELD: machine building.

SUBSTANCE: disc-shaped resilient element comprises frame, in which there are two opposite elastic element of dish type: top and bottom. Each of the disc-shaped resilient elements comprises two flat resilient coaxially set rings: of smaller diameter and of greater diameter. 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. 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. Lower part of the framework consists of a base made as a disc with ring inner groove. Lower disc-shaped resilient element's lower resilient ring of greater diameter is set in the disk groove. 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. Between base of spring and lower cover there are three intermediate damping layers.

EFFECT: efficient damping in resonance mode.
