MARINE ENGINE VIBRATION ISOLATION SYSTEM Russian patent published in 2014 - IPC F16F15/04 B60K5/12 

FIELD: engines and pumps.

SUBSTANCE: invention relates to means of protection against vibration. System comprises rigid bearing carcass to make load bearing surface for power plant and bumpers connecting the carcass with the bed. Engine and diesel generator are secured via bumpers at load bearing carcass. Load bearing carcass is connected with four bumpers attached at ship bulkhead. Bulkhead is coupled with lead bearing carcass by two elastic dampers composed by rubberised cable. Bed of said bumpers is fastened to ship bulkhead via damper The latter represents a combined spring-mesh design and comprises the case, interconnected flat ring resilient elements and coaxial cylindrical rod. Said case is composed of cylindrical shell with bore for locking the resilient spring element outer ring while cylindrical rod has bore for locking of inner ring. Said resilient spring element is composed by two resilient coaxial rings connected by two symmetric resilient diametrically located elements with central through groove.

EFFECT: higher efficiency, simplified design.
