PACKAGE OF RING SPRINGS OF DISH-TYPE Russian patent published in 2018 - IPC F16F3/02 F16F1/32 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Package of ring springs consists of a set that includes at least two pairs of opposed and interconnected by large bases of annular elastic conical disks. Inner toroidal surface is formed in the joint of each pair. Outer toroidal surface is formed in the joint of the set of these pairs at smaller base. Every resilient conical disk is fitted by side conical surface with spherical segments located at the greater and the smaller bases of the truncated cone. Spherical segments are directed in opposite directions from the generatrix of the conical surface. Ring spring set is located in a cylindrical casing with its lower part being rigidly connected to the base. Base has a centering cylindrical collar into which the smaller base of one of the resilient conical disk pairs enters. In top part of casing freely with clearance lid with centering cylindrical shoulder is installed. Groove is provided on the cylindrical surface of the casing to reduce its radial stiffness. Damping elements in the form of rivets of polyurethane are located in the holes.

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