PACK OF RING SPRINGS BY KOCHETOV Russian patent published in 2015 - IPC F16F3/02 F16F1/32 

FIELD: machine building.

SUBSTANCE: pack of ring springs consists of a set including at least two pairs of oppositely mounted ring-shaped resilient conical disks interconnected by greater bases. The inner toroidal surface is formed in the joint of each pair. The outer toroidal surface is formed in the joint of the set of these pairs at the smaller base. Every resilient conical disk is fitted by the side conical surface with spherical segments located at the greater and the smaller bases of the truncated cone. The spherical segments are directed in opposite directions from the generatrix of the conical surface. The ring spring set is located in a cylindrical casing with its lower part being rigidly connected to the base. The base has a centring cylindrical collar into which the smaller base of one of the resilient conical disk pairs enters. A cover with the centring cylindrical collar is movably installed in the upper casing part with a gap. A groove is provided on the cylindrical surface of the casing to reduce its radial stiffness.

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