Abstract
Disclosed is a metal vibration reducer which has high damping and a spiral flat spring. The structure of the utility model is as follows: the spiral flat spring is clamped between an upper support sleeve and a lower support sleeve; a damper is supported by the upper support sleeve; the damper is constructed by superposing a horizontal friction plate, an upper damping friction plate, a damping steel wire, a lower damping friction plate and a lower horizontal friction plate from top to bottom; a friction nut is threaded through the damper and the center of the upper support sleeve from up to bottom, making the friction nut be tightly contacted with the damper; the damping steel wire is constructed through winding the metal net on the friction nut; a countersunk bolt is threaded through the lower support sleeve and is in bolt joint with the friction nut through the gasket, making the spiral flat spring be clamped between the friction nut and the gasket; the structures are contained in a shell and a lower plate but the friction nut is exposed outside the shell and then the shell is fixedly connected with the lower plate. The utility model has low natural frequency and transmissibility, wide temperature range and long service life.
Description
Technical field
The utility model is a kind of metal vibration damper that is used on instrument and apparatus and the electronic equipment, the flat spring high damping of particularly a kind of spiral full-metallic vibration damper.
Background technique
Traditional vibration damper that is used on instrument and apparatus and the electronic equipment is rubber absorbers, and rubber absorbers have following shortcoming: natural frequency, transmissibility are all bigger, and the serviceability temperature scope is narrow, and rubber is aging easily, and working life is short.
Summary of the invention
The utility model is to invent the flat spring high damping of a kind of novel spiral full-metallic vibration damper for the shortcoming that overcomes above-mentioned rubber absorbers.
The utility model is realized as follows: the utility model comprises: shell, damper, friction nut, sunk screw, packing ring, last top cover, the flat spring of spiral, following top cover, lower plate, the flat spring of spiral is sandwiched in, between the cover of following top, withstand damper by last top cover again, damper is by last horizontal friction plate, last damping friction plate, damping wire, last damping friction plate, horizontal friction plate from top to bottom is formed by stacking down, friction nut from top to bottom passes the central authorities of damper and last top cover, should make between friction nut and the damper and closely contact, described damping wire is to use wire netting on friction nut, sunk screw passes down the top cover by packing ring and is spirally connected with friction nut, the flat spring of spiral is sandwiched between friction nut and the packing ring, housing and lower plate are dissolved in said structure wherein, should make friction nut expose shell, again with housing and lower plate affixed it.Housing and lower plate can by the hollow rivet affixed it.
Good effect of the present utility model is: when electronic equipment vibrates, rub by connecting friction nut and damper, the upper and lower displacement of the flat spring of spiral is when the natural frequency of vibration damper and the frequency ratio of vibration source surpass
The time by vibration isolation, electronic equipment is played cushioning effect.The utility model natural frequency, transmissibility are all smaller, and the serviceability temperature scope is than broad, long service life.
