Abstract
The utility model relates to a vibration absorber used on precise instruments of aviation and aerospace, particularly a multi-position high-damp full metal vibration absorber. The utility model has the structure that an upper pad, a lower pad, a damper, a lower pad B and a cushion are respectively arranged in a housing from top to bottom, friction nuts are inserted into the centers of the housing, the upper pad, the lower pad A, the damper, the lower pad B and the cushion, and the bottom of each of the friction nuts is connected with a backing board, a casing tube, a pressure board and a spring washer by screws. A top sleeve is arranged on the inner circle of the housing, a cone spring A and a cone spring B below which a bottom wire pad is arranged are arranged above and below the cushion respectively, the housing and the lower board are riveted by hollow rivets, and the top sleeve, the cone spring B and the bottom wire pad are all pressed on the bottom board. The utility model can work normally within the temperature range of from-65 DEG C to 130 DEG C, the resonance magnification can be controlled to be smaller than or equal to 1.5 times, and the effect of vibration isolation reaches above 88%. The utility model can rotate electronic equipment by 180 DEG and realize multidirectional vibration absorption.
Description
Technical field
The utility model is a kind of Aeronautics and Astronautics that is used for, and as fighter, guided missile, rocket, satellite, airship etc. are needed various sophisticated electronicses is carried out the novel damping device of vibration isolation and buffering, particularly a kind of multi-direction high damping full-metallic vibration damper.
Background technique
Traditional vibration damper that is used on instrument, instrument and the electronic equipment, usability is a direction.Current advanced rigidity vibration dampers such as three-dimensional, also can't resolve Aeronautics and Astronautics required to the multi-direction major issue of carrying out vibration damping and buffering of various sophisticated electronicses.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes above-mentioned various vibration dampers, and original a direction or current rigidity vibration dampers such as three-dimensional further are modified into multi-direction high damping full-metallic vibration damper.
The utility model is realized as follows: the utility model comprises shell, Upper gasket, lower levelling plate A, damper, lower levelling plate B, friction nut, screw, backing plate, cushion pad, sleeve pipe, cone spring A, pressing plate, spring washer, cone spring B, top cover, tubular-shank rivet, base plate, following gauze pad.From top to bottom be respectively equipped with Upper gasket, lower levelling plate A, damper, lower levelling plate B, cushion pad in the shell, central authorities in shell, Upper gasket, lower levelling plate A, damper, lower levelling plate B, cushion pad are inserted with friction nut, the bottom of friction nut is bolted with backing plate, sleeve pipe, pressing plate, spring washer by screw, the top that is provided with in interior week of shell is overlapped, be respectively equipped with cone spring A and cone spring B in the above and below of cushion pad, the below of cone spring B is provided with down gauze pad, shell and lower plate are riveted with tubular-shank rivet, and top cover, cone spring B and following gauze pad all are pressed on the base plate.
Good effect of the present utility model is: component all select for use the all-metal material of high strength, rub resistance to be processed into, can under utmost point rugged environment, work, can be in-65 ℃ of one+130 ℃ of temperature ranges proper functioning, there is damper vibration damper inside, resonance reduction factor (transmissibility) can be controlled at≤1.5 times, vibration isolating effect reaches more than 88%, can prolong the working life of electronic equipment and the use validity of raising electronic equipment.Most importantly can realize multi-direction vibration damping to electronic equipment Rotate 180 degree.If compare, all surpass rubber absorbers in every performance index and working life with rubber absorbers.
