VIBRATION-PROOF SUPPORTER FOR SMALL VESSEL MAIN ENGINE

摘要

PURPOSE:To reduce the amplitude of main engine by receiving thrust through vibration absorbing rubber while suppressing resonance through vibration absorbing rubber encapsulated with liquid. CONSTITUTION:Main engine 1 is supported through vibration-proof supporters 5A and 5B between fixing feet 2A, 2B planted at the front and rear and the floor 4 of vessel 3. In order to reduce the amplitude, a rear side vibration absorbing supporter 5B made of vibration absorbing rubber encapsulated with liquid is provided in main engine 1. But since thrust is applied onto the rubber body 23 to deform considerably, total rubber body is employed for the front side supporter 5A to bear the thrust force.
