DISK-SHAPED RESILIENT ELEMENT Russian patent published in 2015 - IPC F16F3/02 F16F1/32 

FIELD: machine building.

SUBSTANCE: disk-shaped resilient element comprises two disk-shaped resilient elements set symmetrically to a separating disk. Each resilient element comprises a dished surface in the form of a truncated cone, the said surface is provided with three through grooves forming two truncated conical surfaces connected by three fins which are directed along generating lines of the conical surface. Damping cylinders made from cast polyurethane are fixed in the central part of the separating disk and enter the holes at the truncated conical surfaces' vertices with a gap. The damping cylinders are interconnected by a resilient insert consisting of an axle and thrust disks. The resilient insert axle passes through the holes in the separating disk and damping cylinders. The thrust disks of the resilient insert provide for the connection of the upper and lower damping cylinders with the separating disk and fixation of the resilient disk-shaped elements in respect to the separating disk.

EFFECT: increased efficiency of vibration isolation in a resonance mode.
