Abstract

The invention relates to a three-way frictional damping force adjustable vibration isolator for a ship, which comprises a base, an upper cover, a vibration isolation spring component and a damping buffer component, wherein the damping buffer component comprises a friction ring, friction pieces and a support plate; a cylindrical bulge is arranged at the middle part of the support plate; the friction pieces are axially and fixedly arranged on the cylindrical bulge in a sleeving manner; and outer ring faces of the friction pieces are contacted with the internal surface of the friction ring. The vibration isolator has the advantages of higher abrasion resistance, higher corrosion resistance and the like, and solves the problems that the available rubber vibration isolator is easy to age and the metal vibration isolator is easy to abrade. In addition, the three-way frictional damping force adjustable vibration isolator for the ship has higher spacial three-way vibration isolation buffer and shock resistances, and the adjustment of a three-way frictional damping force is very convenient.

Description

technical field [0001] The invention relates to a vibration isolation buffer device, in particular to a vibration isolator with adjustable three-way frictional damping force suitable for protecting electronic equipment or electromechanical equipment on ships. Background technique [0002] Vibration and shock can cause mechanical damage to electronic or electromechanical equipment, components or materials, causing structural deformation or loosening, changes in electrical parameters, and poor contact. Therefore, in addition to stress screening of components and sub-boxes in electronic equipment, and structural reinforcement of the whole machine to improve its ability to resist mechanical environments, vibration isolators should also be used to alleviate or avoid the harmful effects of mechanical environments on electronic equipment, in order to achieve The purpose of reducing the reinforcement cost of electronic equipment and improving its reliability and service life. In ad...
