Accompanying drawing explanation
Fig. 1 is the main sectional view of structure of the present utility model;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is cylinder type metal rubber load-displacement diagram figure;
Fig. 4 is the utility model embodiment's effectiveness in vibration suppression figure.
Embodiment
Below in conjunction with accompanying drawing and embodiment, embodiment of the present utility model is further illustrated.
As Fig. 1, shown in 2, a kind of metal-rubber crystal oscillator vibration damping equipment, for reducing the vibration of crystal oscillator 5, comprise regulate guide pillar 1, cylinder type metal rubber 2, just overlap 3, bracket 4, lock sheet 6, base plate 7 etc.
Crystal oscillator 5 is installed on bracket 4,4 four angles of bracket are connected with base plate 7 with damping connecting screw rod with four adjustable rigidities, each adjustable rigidity and damping connecting screw rod by regulating guide pillar 1, cylinder type metal rubber 2, just overlap 3, lock sheet 6 forms, regulate guide pillar 1 through cylinder type metal rubber 2, just overlap 3, bracket 4 is threaded with lock sheet 6.In the middle of bracket 4, be groove, place 5, four angles of crystal oscillator with boss in groove, boss is fixedly connected with firm cover 3.Cylinder type metal rubber 2 is partially submerged in firm cover 3.
Can regulate the pre compressed magnitude of cylinder type metal rubber 2, thereby regulate vibration damping equipment rigidity and damping to arrive suitable value by regulating being threaded of guide pillar 1 and lock sheet 6, obtain best effectiveness in vibration suppression; Cylinder type metal rubber 2 parts are embedded in firm cover 3, can play three-dimensional damping effect; Crystal oscillator 5 is arranged in concave cradle 4, vibration damping equipment is arranged in to the gravity plane of crystal oscillator 5, avoids coupled vibrations, improves damping property.
As shown in Figure 3, the load-displacement diagram of cylindrical metal rubber 2, its power and displacement relation have the Variation Features of linearity-software feature-hardware features.When displacement is very little, the slippage between the wire in metal-rubber element is very little, is mainly the stand under load distortion of the helical spring self in metal-rubber element, and its rigidity is almost constant, i.e. it is linear that power and displacement is, and damping is very little; When displacement increases, the helical spring in metal-rubber element is in contact with one another, and occurs with sliding phenomenon in various degree, thereby makes Stiffness, i.e. power and displacement is software feature, and damping increases; When displacement continues to increase, the helical spring in metal-rubber element is in contact with one another extruding, and sliding phenomenon weakens, and rigidity increases, i.e. power and displacement is hardware features.Therefore the vibration damper made from metal-rubber, when displacement constantly changes, vibration damper can present different rigidity and damping characteristic.
As shown in Figure 4, the effectiveness in vibration suppression figure of a kind of metal-rubber crystal oscillator of the utility model vibration damping equipment specific embodiment.
In sum, a kind of metal-rubber crystal oscillator of the utility model vibration damping equipment, simple and light, easy for installation, there is stiffness and damping adjustable, three-dimensional damping property is good, excellent in durability, high temperature resistant, low temperature, corrosion resistance, be difficult for the advantages such as aging, has very strong practicability and wide application prospect.
