Abstract
The utility model discloses a rubber vibration isolator with a large load and a high damping. The utility model consists of a rubber core block(1), an adjusting device(2), a supporting cover(3), a top cover(4) and a tightening bolt(5); the inner layer or the surface of the adjusting device is provided with a damp layer(6); the adjusting device and the rubber core block are positioned in the supporting cover after connecting in series; and the top cover is fixed and connected with the supporting cover(3) through the tightening bolt. The utility model has a rational structure; the utility model is able to preset the necessary low fixed frequency, the high bearing capability and the high damp ratio through the mutual action of the adjusting device as that the rubber core block is provided with an adjusting device to adjust the intensity of the core block and the damp; the fixed frequency is able to reach three Hz; the bearing capability is able to reach four hundred kN to one thousand and two hundred kN; and the damp ratio is able to reach zero point twenty five. The art of the utility model is simple and without model require and has a low product cost. The utility model enhances applicable range of the rubber vibration isolator and is applicable to the forge hammer and the rubber vibration isolator with a large load and a high damping of the large punching machine.
Description
Technical field
The utility model belongs to the vibration isolation technique field, and what relate generally to is a kind of big load high-damping rubber vibration isolator.Be applicable to the large-scale active vibration isolation of equipment and the passive vibration isolation of large-scale precision equipment of shaking by force.
Background technique
There is following application limitation in existing rubber vibration isolator: the one, bearing capacity is low, generally about several kN within tens kN, the 2nd, the natural frequency height, generally more than 6Hz, the 3rd, damping ratio is low, is generally between 0.08～0.10.Therefore rubber vibration isolator is difficult to use in the vibration isolation that forging hammer and press machine etc. focus on large-scale shake by force equipment and large-scale precision equipment and other low frequency equipment of 1000kN～30000kN certainly.At present, the domestic and international damping spring vibration isolator that adopts at large-scale shake by force equipment and large-scale precision equipment, as be used for large-scale forging hammer vibration isolation, problem such as spring breakage often occurs, damping agent leaks and anvil block is crooked, even anvil block takes place shake and split.Therefore some developed country has stopped at and has adopted the damping spring vibration isolator on the important equipment that shakes by force.The development of its substitute products has been current safety and environment-friendly products problem anxious to be solved.
" dull and stereotyped rubber vibration insulating pad " patent (ZL 92 231422.5) by Design Inst. No. 4, Ministry of Machine-building and Electronics Industry's application has reduced its natural frequency, improved damping ratio, but in use still there is the not high enough problem of its bearing capacity and damping ratio in it.
Summary of the invention
The purpose of this utility model promptly produces thus, proposes a kind of big load high-damping rubber vibration isolator.Improve its bearing capacity and damping ratio, reduce its natural frequency effectively, thereby widen the rubber vibration isolator application area, and can be directly used in the rubber vibration isolator of the big load high damping of forging hammer and large pressing machine.
For achieving the above object, the technological scheme that the utility model is taked is: it is by rubber pellet, regulating device, supporting sleeve, top cover and give tight bolt and constitute, the inside interlayer or the surface of regulating device are provided with damping layer, this regulating device is connected with the rubber pellet and is placed in the supporting sleeve, is fixedlyed connected with supporting sleeve by giving tight bolt by top cover.
The utlity model has following advantage:
1, improved the bearing capacity of rubber vibration isolator, can be increased to 1200kN by tens kN.
2, improved the damping ratio of rubber vibration isolator, can be increased to 0.25 by 0.10.
3, reduced the natural frequency of rubber vibration isolator, can further reduce to 3.0Hz by general minimum 6Hz.
4, widened the rubber vibration isolator application area, not only can be used for the above vibratory equipment of 1000r/m, and can be used for the low frequency equipment of 400r/m, its frequency range is equal to existing damping spring vibration isolator.Because its damping ratio increases substantially, and can be used for the equipment that shakes the by force vibration isolation of large amplitude, as forging hammer, press machine etc.Problems such as spring breakage, damping agent leakage and the anvil block of having avoided the damping spring vibration isolator often to occur is crooked.
5, reduced manufacture cost, can have been made by ordinary rubber factory, do not had the mould requirement substantially, its supporting sleeve is general plumber's operation, need not machining apparatus.The intensity of used raising rubber vibration isolator and the material of damping can utilize the industrial waste in some factory such as foundry, cement plant.

Embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in Figure 1, it is by rubber pellet 1, regulating device 2, supporting sleeve 3, top cover 4 and give tight bolt 5 and constitute.What rubber pellet 1 adopted is " dull and stereotyped rubber vibration insulating pad " patent (ZL 92 2 31422.5) of Design Inst. No. 4, Ministry of Machine-building and Electronics Industry's application, its appearance is smooth block rubber, inner hole of adopting entity or double isosceles trapezoid hole, equilateral, isosceles triangle hole or other form by requirement of engineering is through the punching moulding.The thickness of rubber pellet 1 and usage quantity are determined by the vibration isolation engineering design.As shown in Figure 2, regulating device 2 adopts the material with good toughness higher than rubber core bulk strength, can be designed to sheet or strip according to requirement of engineering, and its inside or surface are provided with damping layer 6, and described damping layer adopts conventional damping material to make.Interact after this regulating device 2 is connected with rubber pellet 1, just can reach low natural frequency and the high-bearing capacity and the high damping ratio of design.Because the rubber pellet 1 of multilayer is with after regulating device 2 is connected, because of its horizontal rigidity is crossed low its design advantage that is difficult to bring into play.Therefore supporting sleeve 3 is set, as shown in Figure 3, supporting sleeve 3 is a frame structure, which is provided with pore 7.After rubber pellet 1 and regulating device 2 place in the supporting sleeve 3, fixedlyed connected with supporting sleeve 3 its horizontal rigidity is greatly improved by giving tight bolt 5 by top cover 4, low natural frequency, high-bearing capacity and the high damping that makes present embodiment is than promptly so and give full play to.
The utility model connects by top cover 4 and by device for vibration insutation base or inertial mass bottom surface in use.
The utility model can be designed to the load of 400kN～1200kN according to customer requirements, and its damping ratio can be selected between 0.15～0.25, and its natural frequency can be by being designed to 3.0Hz～8.0Hz by the device for vibration insutation forcing frequency.
