Abstract
The utility model relates to a hemi-spherical metallic rubber buffer which is shock resisting and applicable for light load supporting, comprising such main vibration-damping elements as a hemi-spherical metallic rubber and a hollow cylindrical metallic rubber. The utility model is wound by corrosion resistant twisted metal wires in accordance with a certain rule and compressed into a texture body of elastic cellular materials. The texture body is similar to the molecular chain structure of rubber materials and is provided with a fine elasticity and dry frictional damping property. The utility model is characterized in that the utility model applies anti-overloading protective measures and can normally be operated in conditions of excessive amplitude, realizing the effect of isolating and absorbing vibration, in addition, the utility model is provided with a self-locking function, protecting the load from disengaging due to the excessive amplitude. The utility model has the advantages of a high temperature resistance, a low temperature resistance, a temperature large variation resistance, a corrosion resistance, a long life and less volatilization in vacuum.
Description
Technical field
The utility model relates to a kind of underload, shock proof vibration damper of being used for.
Background technique
For Aero-Space, peculiar to vessel and vehicle-mounted vibration damping and vibration isolations such as instrument and equipment, need vibration damper to have stronger buffering, impact resistance, have very high stability and serviceability.And traditional rubber vibration isolator be difficult to adapt to, so a kind of vibration damper that can proper functioning under rugged environment of needs.
The model utility content
Under rugged environment, be difficult to use in order to overcome the General Purpose Rubber vibration damper, a kind of shock proof metal-rubber vibration damper is provided.
This model utility can realize in the following way: a kind of hemisphere shell mould vibration damper, it is characterized in that: it comprises a hemispherical Shell metal-rubber test specimen and two hollow cylinder metal-rubber test specimens, the open end of this hemispherical Shell metal-rubber test specimen is fixed on the base by pressure ring, one mandrel passes the center and the base of hemispherical Shell metal-rubber test specimen, the part that mandrel is positioned at hemispherical Shell metal-rubber test specimen inside is " worker " font, and hollow cylinder metal-rubber test specimen is fixed near the upper and lower sides of base that mandrel passes.
The metal-rubber test specimen is that the shape wire that revolves by corrosion-resistant spiral shell twines according to certain rules, and compacting forms the structure of elastic porous material again; The molecular chain structure of the similar General Purpose Rubber of this structure has better elastic and dry-friction damping performance.
The utility model has overcome that the General Purpose Rubber vibration damper can only compress and the defective that can not stretch has realized compression and the dual functions that stretches, and is reliable and stable; It has overload protection function, promptly under the situation that load is excessive or amplitude is excessive, also can be good at vibration isolation and damping; It also has the effect of three-dimensional vibration damping and vibration isolation.When mandrel was done reversal of vibrations, the utility model played the function of self-locking, avoided load to break away from because of inertia is excessive.The utlity model has corrosion-resistant, high-low temperature resistant, shock resistance, characteristics such as the life-span is long, intensity is big, the chemical composition of material is non-volatile under the vacuum.
Description of drawings
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the structural representation of the utility model mode of execution one,
Fig. 3 is the structural representation of the utility model mode of execution two.
Among Fig. 1: 1 mandrel, 2,5,11 nuts, 3 lock washers 4 are by vibration isolation object 6 spherical washers 7,10 hollow cylinder metal-rubber test specimens 8 hemisphere hull shape metal-rubber vibration dampers 9 nylon guide sleeves 12 bolts 13 pressure rings 14 bases
Embodiment
Referring to accompanying drawing 1, vibration damper described in the utility model, its core component is a hemispherical Shell metal-rubber test specimen 8 and two hollow cylinder metal-rubber test specimens 7,10, the open end of hemispherical Shell metal-rubber test specimen 4 is fixed on the base 14 by pressure ring 13 fitted bolts 12, one mandrel 1 passes the center and the base 14 of hemispherical Shell metal-rubber test specimen 8, the part that mandrel 1 is in hemispherical Shell metal-rubber test specimen 8 inside is " worker " font, hollow cylinder metal-rubber test specimen 7,10 is fixed near base 14 upper and lower sides that mandrel 1 is passed, round mandrel 1.
Working principle: during by vibration isolation object 4 vibration downwards,, just play the effect of vibration damping by nut 5 and spherical washer 6 compressing hemispherical Shell metal-rubber test specimens 8.When amplitude was excessive, hollow cylinder metal-rubber bounding means 7 worked simultaneously, thereby hemispherical Shell metal-rubber test specimen 8 can not destroyed because of deformation is excessive.When (oppositely) vibration that made progress by vibration isolation object 4, hemispherical Shell metal-rubber test specimen 8 strength play effectiveness in vibration suppression; In case deformation surpasses when a certain amount of, hollow cylinder metal-rubber bounding means 10 is simultaneously also stressed, and spherical shell metal-rubber test specimen 8 is played a protective role.
Mode one: as shown in Figure 2, directly adopt nut one bolt that the utility model bottom is connected with base 14, top is being fixed by vibration isolation object 4.For effective and stable support heavy load, adopt three or four the utility model to support.
Mode two: as shown in Figure 3, adopt nut-bolt that " point " formula is formed on the utility model bottom and support, top is by vibration isolation object 4, and the bottom is a base 14.
Claims (2)
1, a kind of hemisphere shell mould vibration damper, it is characterized in that: comprise a hemispherical Shell metal-rubber test specimen and two hollow cylinder metal-rubber test specimens, the open end of described hemispherical Shell metal-rubber test specimen is fixed on the base by pressure ring, one mandrel passes the center and the base of described hemispherical Shell metal-rubber test specimen, the part that described mandrel is positioned at hemispherical Shell metal-rubber test specimen inside is " worker " font, and described hollow cylinder metal-rubber test specimen is fixed near the upper and lower sides of base that mandrel passes.
2, as the said hemisphere shell mould of claim 1 vibration damper, the metal-rubber member that it is characterized in that is that the shape wire that revolves by corrosion-resistant spiral shell twines according to certain rules, and is compressed to the structure of elastic porous material.
