DISK-SHAPED RESILIENT ELEMENT Russian patent published in 2018 - IPC F16F3/10 F16F1/32 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building. Disk-shaped resilient element comprises frame, in which the resilient element is installed. Frame lower part consists of base made in the form of disk with the inner annular groove. Resilient element contains two flat resilient coaxially located rings. Rings are coupled to each other by three flexible flat disks between the grooves inclined to the rings’ axis. Bottom ring of the resilient element is located in the disk groove. To the lower ring bottom part ring from friction material is attached to ensure dry friction. Frame upper part is made in the form of cover, which is a disk with the central annular groove. Cover is rigidly connected to the resilient element upper ring by means of screws. Layer of vibration damping material from polyurethane is arranged in the central ring groove of the cover, and a mounting plate to hold the unit whose vibrations are to be isolated is fixed on the said layer. Friction ring is attached to the lower part of the lower ring and is made of a copper-based material.

EFFECT: enabling the vibration isolation in resonance mode increased efficiency.
