Axial vibration damper with diaphragm controller for main engine in ship

摘要

The present invention relates to a damper for damping the ship is provided with a longitudinal tolerance period diaphragm control, in particular are both coupled to the distal end ( ) portion of the shaft is provided in a marine engine oil through a diaphragm valve which is provided to the damper to damp the former, the rear vibration in the crank to decrease the residence sphere around the longitudinal vibration, move backward The ship that is capable of controlling the diaphragm vibration damping provided by species tolerant species damper adjustment relates to the period for vibration damping. The present invention provides a damper for damping longitudinal vibration is coupled to surround a cam coupled to the end of the crankshaft provided in the engine main organ of the vessel, and the oil is received in the interior in contact with both side portions of the cam, the said oil together and a communication path to be oil chamber of a pair is connected by a passage and a valve for adjusting the amount of oil flowing through the clearance by adjusting the area of the flow path, and a control unit for controlling an opening degree of the valve to flow. ;
