CIRCULAR CONICAL SPRING Russian patent published in 2018 - IPC F16F3/02 F16F1/32 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building. Circular cone spring consists of a set of conical discs. One outer and two inner circular elastic conical discs are located between the base and the spring cover. Three radial grooves are directed from the larger base of the truncated cone to the smaller base. Each of the radial slots is ended by hole for stress relieving. Conjugation of the lateral conical surfaces of the outer circular elastic conical disks with the lateral conical surfaces of the inner circular elastic conical disks is made in the form of spherical segments. Spherical segments are made integrally with the conical surfaces of each of the disks and are directed in different directions from the forming conical surface. Lateral conical surfaces of the inner circular elastic conical disks and spherical segments are covered with polyurethane.

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