Below by vertical impact analysis, side knock analysis and torsional impact analysis to steel-wire isolator of the present invention, specify working principle of the present invention:
One, vertical impact analysis
When device was in original state, spring was in preloading condition under top board and plunger action of gravitation, but this moment, top board did not contact with punch holder one, i.e. spacing A〉0; When top board is subject to impacting, at first be that spring plays damping effect, this is the one-level vibration isolation; Excessive when impacting, so that during spacing A=0, top board contacts with punch holder one, namely fitting surface II is in contact with one another, and exciting can be passed on the wire rope, and the while spring still has damping effect, has consisted of like this combination vibration isolator parallel with one another, and this is the secondary vibration isolation; Continue to increase when impacting; so that when spacing B=0 and C=0, the sleeve upper surface contacts with punch holder two, the fitting surface I of plunger lower end and sleeve also is in contact with one another simultaneously; with the protection wire rope, prevent from causing when load that wire rope bears from surpassing its limit load fractureing of wire rope.In these above mechanisms, when plunger moved in sleeve, the valve sealing on the die holder stoped the air in the plunger guide bush cavity outwards to flow out; When plunger moves upward, the pressure decreased in the sleeve cavity, valve is opened under inside and outside atmospheric effect, and air is entered in the cavity, and plunger can be resetted rapidly.
This vibration isolator has definite spatial position demand, and this is because the maximum vertical quiet amount of deformation of vibration isolator is defined: 1. when plunger moved upward, the macromolecule layer that vulcanizes on the plunger had limited its maximum rising displacement; 2. when plunger moved downward, the fitting surface of plunger base and sleeve bottom had limited its maximum decline displacement; The maximum vertical deviation that is installed in like this machinery equipment on the vibration isolator can be determined, thereby is conducive to select suitable vibration isolator according to the space size at scene, and the utilization ratio in space is improved.
Two, side knock analysis
1, as spacing A〉0 the time, the side knock of system is mainly taken by macromolecule layer and wire rope that plunger, sleeve match; Part side knock is delivered to plunger by top board, is delivered to wear ring again, is delivered to wire rope by top board at last, is absorbed by wire rope; Another part side knock is absorbed by the macromolecule layer on plunger, the sleeve fitting surface.
2, when spacing A=0, macromolecule layer and wire rope three between the macromolecule layer that the side knock of system is mainly matched by plunger, sleeve, top board and the punch holder one take jointly; Macromolecule layer between top board lower surface and punch holder one upper surface is in contact with one another, and will produce rubbing action, thereby absorbs a part of side knock.
3, the stability in order to guarantee that it is horizontal, the whole configuration design of vibration isolator is become square body shape (when the free state), after vibration isolator is installed in the system, size will be less than transverse dimension longitudinally for it, the moment that horizontal force is produced diminishes, thereby improves its lateral stability.
Three, torsional impact analysis
1, under the little percussion: plunger can be done rotation motion around its axis, so that the torsional vibration of transmission equipment; When plunger produces rotation motion, it will contact gradually with the side macromolecule layer of sleeve, and generation frictional damping effect, because this fitting surface is symmetric shape, so its damping can double, the effectiveness in vibration suppression of utilizing simultaneously the Coulomb damping principle to produce is higher than the effectiveness in vibration suppression of the resiliently deformable acquisition that only depends on the polymer material layer that cooperatively interacts between plunger and sleeve far away.
2, under the large impact effect: device is subject to the time spent of doing of greater impact, top board and punch holder one and fitting surface II all are in contact with one another, thereby produce the frictional damping effect, this moment, wire rope began to work and shared a part of impact, and the damping function of the fitting surface I between plunger guide bush is superimposed, and torsional excitation power is consumed very soon.
Below be determining about the spacing A among the present invention, B, C:
1, spacing B
Spacing B is relevant with the load rating N of wire rope and the maximum quiet amount of deformation a under load rating thereof; can get spacing B=a; like this when the load of wire rope reaches its load rating; the sleeve upper surface just contacts with punch holder two; sharing the one partial load, thereby reach the purpose of protection wire rope.
2, spacing A
Spacing A and spring and protected weight of equipment G
0, top board and plunger gross weight G relevant, establishing the maximum quiet amount of deformation of choosing spring is D, the rigidity of spring is k, then has
3, spacing C
In order to guarantee as vibration isolator (at spacing B=0 time) when affording maximum load spacing C=0 to be arranged, and this moment spring the decrement of decrement during less than its load rating, then spacing C should satisfy: 1. spacing C=A+B; 2. establish stiffness K and the load rating E thereof of spring, quiet amount of deformation is D=E/K, then C≤D should be arranged.
In addition, the present invention can carry out type selecting to each parts for concrete use condition, as: 1. wirerope diameter, number of share of stock; 2. the diameter of sleeve, plunger; 3. the selection of spring; 4. the correlation between each parts is selected can be with reference to accompanying drawing 12.
The present invention is not subjected to the restriction of above-mentioned mode of execution, and other any do not deviate from change, the modification done under Spirit Essence of the present invention and the principle, substitutes, combination, simplify, and all should be the substitute mode of equivalence, is included within protection scope of the present invention.
