DEVICE FOR VIBRATION INSULATION OF SHAFT LINE WITH BEARINGS AND SCREW PROPELLER OF SHIP HULL Russian patent published in 2016 - IPC B63H21/30 F16F15/00 

FIELD: shipbuilding.

SUBSTANCE: invention relates to reduction of dynamic forces transmitted from screw to ship hull through shafting, and concerns reduction of variable hydrodynamic forces transmitted through shafting on to ship hull. Shafting vibration insulation device with bearings and screw propeller from ship hull comprises “screw propeller-shafting-support and thrust bearings of propulsion shaft” system with one-stage vibration-isolating attachment. One-stage vibration isolating attachment includes vibration absorbers of support and thrust bearings. System is installed in ship hull via two-stage vibration isolation system, which consists of external and internal stages of vibration isolating attachment with intermediate frame. Intermediate frame is mounted on ship hull on vibration absorbers, which together form an external stage. Rigidity centres of internal and external stages coincide with corresponding gravity centres of total loads from shafting.

EFFECT: increase and preservation of vibration isolating effect.
