The utility model discloses when receiving the vibration of great magnitude, all can play better vibration isolation and buffering complementation in X, Y, three orientations of Z, guarantee that its inside electronic equipment runs well to simple to operate, simple structure.
Description
Technical field
The utility model relates to a kind of metal species damping buffer device of multi-direction, high damping, especially can be applicable to the frictional damping vibration damper of low frequency large amplitude and large magnitude vibration.
Background technique
Mostly existing vibration damper is in the middle part of bowl-shape frame, install a damping device additional or install damping device additional at bowl-shape frame top, and this vibrational power flow is when especially durability is vibrated in the vibration running into relatively large level, damped system function easily weakens, cause and increasing through resonance region magnification factor, thus contained spring is squeezed or shear action causes damage.
Model utility content
In order to overcome the deficiencies in the prior art; namely in order to cut down magnification factor during resonance; protection vibration damper contained spring and electronic equipment are not damaged; the utility model provides a kind of frictional damping vibration damper; this vibration damper has the features such as multi-direction, low natural frequency, high damping, also has excellent antifatigue and shock-absorbing capacity simultaneously.
The utility model solves the technological scheme that its technical problem adopts:
Good effect of the present utility model: a kind of frictional damping vibration damper, comprise the bowl-shape frame of top drilling and the base plate of bottom thereof, bowl-shape frame inside is provided with sleeve, the damping fin contacted with it is provided with in sleeve, lining is provided with in damping fin, frame plate and upper conical spring is provided with above lining, below is provided with lower frame plate and inferior pyramidal spring, upper conical spring and the symmetrical distribution of inferior pyramidal spring, nut is inserted with in upper conical spring, the attachment screw be connected with described nut is inserted with in inferior pyramidal spring, described lining overcoat has packing, damping fin produces to rub by the elastic force of packing and sleeve lining and forms damping, in bowl-shape frame, the top of upper conical spring is disposed with the lower levelling plate of crimping mutually, Intermediate gasket, gauze pad in upper, upper outside gauze pad and Upper gasket, Upper gasket crimps mutually with bowl-shape frame inside top.
Preferably, described inferior pyramidal spring inner bottom part is provided with cushion pad.
Preferably, spring washer is provided with between described attachment screw and nut.
Preferably, fixed by closing-up between described base plate and bowl-shape frame.
Preferably, dust-proof cover is provided with above described bowl-shape frame.
The beneficial effects of the utility model: the utility model damping fin produces to rub by the elastic force of packing and top cover inwall and forms damping, when vibration damper is in the vibration of bearing axial direction, this damped system works, kinetic energy is converted to heat energy, and heat energy is dispersed in the middle of air thus plays the effect of cutting down vibration; In radial level direction, nut is installed successively lower levelling plate, Intermediate gasket, upper interior gauze pad, upper outside gauze pad, Upper gasket, make to produce friction damping force between each part by the pressure of top cover, and kinetic energy is converted to heat energy, make vibration obtain effective attenuation; At the volute spring placed inside cushion pad of bottom, when there being impact condition to occur, cushion pad can effective apparatus with shock absorbing, reaches the effect of protection electronic equipment.The utility model is when being subject to the vibration of relatively large level in a word, X, Y, Z tri-direction all can play good vibration isolation and buffering complementation, ensure that the electronic equipment of its inside runs well, and easy for installation, structure is simple.
