SHOCK ABSORBER Russian patent published in 2012 - IPC F16F3/87 F16F1/40 

FIELD: machine building.

SUBSTANCE: shock absorber includes sleeve located in the centre, holder for attachment of shock absorber to base and elastomeric elastic elements consisting of two parts and placed in holder. External surface of each part of elastomeric elastic element is formed with cylindrical surface which is continued on one side to part of toroidal surface, and on the other side - to conical surface. Cylindrical cavities are uniformly located on conical surface of each part of elastomeric elastic element. A bore in the form of part of toroidal surface is made in the centre of each part of elastomeric elastic element on the side of conical surface. Holder consists of two parts in the form of shells having the shape of flattened straight circular cones, with central holes at each bottom of the shell, which is counted as top of flattened cone, and edges of shells are counted as bases of cones rigidly attached to each other along their end plane. Washer is located on sleeve in middle part of shock absorber, to which external toroidal surfaces of parts of elastomeric elastic element are connected on both sides. One end of sleeve is taken out through a hole at the bottom of the first shell to be attached to equipment. The other end of sleeve is provided with thickened pivot and faces the hole of the second shell.

EFFECT: improving reliability of shock absorber and vibration insulation efficiency.
