Title:
VIBRO-ISOLATING STAY DEVICE
Document Type and Number:
Japanese Patent JPS6131738
Kind Code:
A
Abstract:
PURPOSE:To obtain an effective vibro-isolating effect through the range of all exciting frequencies by making a vibro-isolating stay dismountable and constantly controlling said stay as that the vibration frequency thereof will not be resonated with any of the exciting frequencies by use of two vibration characteristics provided for said stay when it is mounted and dismounted. CONSTITUTION:A primary base board 12 and a secondary base board 13 are stuck to the bearing side for stay of a hull or the like and the side of a vibrator such as a Diesel engine or the like, respectively. A pair of upper and lower joining boards 14a and 14b have, at one end thereof, the primary base board 12 firmly held therebetween while having, at the other end thereof, the secondary base board 13 firmly held therebetween via a pair of upper and lower friction boards 18a and 18b by use of a tension bolt 19. Tension bolt loosening devices 22 and 23 are disposed at the head of the tension bolt 19. The two vibration characteristics which differ from each other when the vibro-isolating stay is mounted and dismounted are selected by use of the devices 22 and 23.
