RUBBER-METAL SHOCK ABSORBER WITH AXIALLY-YIELDING STOP Russian patent published in 2007 - IPC F16F7/12 F16F13/00 F16F15/08 B63H21/30 

FIELD: mechanical engineering; shipbuilding.

SUBSTANCE: invention is designed for flexible fastening of equipment and instruments of ships and it can be used in other industries where antishock effective protection of equipment from external vibrations and shocks should be provided. Proposed rubber-metal shock absorber contains base, rod, two support rubber bushings, fluoroplastic gasket installed between rod and support rubber bushings, thrust rubber bushings and steel plates. Moreover, shock absorber contains fluoroplastic gaskets installed between steel plates and between upper and lower faces of intermediate housing or foot of equipment and which are pressed-in into equipment foot or hole intermediate housing. Shock absorber includes also protective polyurethane ring polyurethane washers installed and pressed-to in base. Invention provides effective protection of equipment from external vibrations and shocks, prevents transmission of natural sound vibrations of equipment to foundation and surrounding structures, ensures strength and long service life of shock absorbers and forecasting of their parameters over all axes and in time, limits displacement of equipment relative to foundation at ship rolling and at impact loads, provides possibility of simple ceiling and deck fastening of equipment with designed inner prevention of breaking off of equipment from place in case of damage of rubber parts.

EFFECT: improved protection of equipment.
