VALEING DEVICE OF SHAFT LINE WITH BEARINGS AND PROPELLER SCREW FROM VESSEL HULL Russian patent published in 2020 - IPC B63H21/30 

FIELD: shipbuilding.

SUBSTANCE: invention relates to shipbuilding and is intended to reduce dynamic forces transmitted from propeller to ship hull via shaft line, and serviceability of resilient suspensions of stern thrust tube together with thrust bearing. Vale-isolation device of the shaft line with bearings and propeller screw from the ship hull includes the system "propeller screw – shafting system – support and thrust bearings of the propelling shaft", which is rigidly mounted inside the stern tube, installed on at least one annular elastic casing. Said system comprises thin-layer rubber-metal element between sternpipe and vessel hull to be secured to vessel hull on one side and opposite side to the support flange added to the stern pipe structure.

EFFECT: improved vibration isolating properties of elastic suspension system.
