Its effectiveness in vibration suppression can not perform to optimum state.And currently for the research how promoted in terms of its effectiveness in vibration suppression, it is most of
The material composition for changing rubber, formula, process are concentrated on, but this mode requires a great deal of time and money,
Therefore quite limit to.And the structure type for changing damping gasket equally exists great influence for its damping property, to this respect
Research then rarely seen innovation.
Utility model content
The purpose of this utility model is to provide vibrational energy can be absorbed, vibration is blocked to transmit, there is effectiveness in vibration suppression
A kind of vibration isolation rubber damping gasket of groove structure.
What the purpose of this utility model was realized in：A kind of vibration isolation rubber damping gasket of groove structure, the rubber
Glue damping gasket surface is provided with the groove with damping rubber gasket central axis axisymmetricly, and all grooves are each parallel to center
Axis, alternatively, all grooves that the rubber damping gasket surface is provided with favour central axis with equal angular.
The fluted width t of the institute and depth all same, the spacing all same between all two neighboring grooves, and
All grooves run through rubber damping gasket upper surface；The rubber damping gasket is rectangle, and at least one groove
Center line passes through the rectangular central point.
The flute length of the groove is the length of rectangular rubber damping gasket short side, and the groove width t of groove is rectangular rubber
The 1/10 of the long edge lengths of damping gasket, the depth h of groove is between the 1/3~1/2 of rubber damping gasket integral thickness.
The central axis angulation of all grooves and rubber damping gasket is equal 45 °；The depth h of the groove exists
Between the 1/3~1/2 of rubber damping gasket integral thickness.
For the rubber damping gasket suitable for all kinds of mechanical systems, surface is provided with evenly arranged groove in a particular form
Structure compared to the rubber damping gasket of ordinary construction, inhibits unstable vibration, the effect of noise phenomenon more notable, energy
The safe operation of mechanical system is effectively ensured, improves service life.And the rubber damping gasket convenient material drawing, structure type are convenient for
Processing, is readily produced manufacture and popularization.
Technical solution is used by the utility model solves its technical problem：A kind of vibration isolation rubber damping of groove structure
Gasket, it is characterised in that：The rubber damping gasket surface is provided with evenly arranged groove structure in a particular form, specific body
It is parallel to each other between groove now to be centrosymmetric with damping gasket central point or the groove with central axis axisymmetricly.
Compared with prior art, the beneficial effects of the utility model are：
First, the utility model is in rubber damping gasket surface by being provided with evenly arranged groove structure in a particular form,
And apply it in mechanical system, by absorbing vibrational energy, vibration is blocked to transmit, mechanical system is protected not to be damaged.This
The vibration isolation rubber damping gasket of groove structure described in patent is mainly provided on its surface to be centrosymmetric or with central point in
The mandrel line groove that axisymmetricly form is arranged.During mechanical system generates unstable vibration, pass through rubber sheet gasket surface
The rigidity deformed to change gasket different zones of " boss " between adjacent trenches, contact should between realizing adjacent machine structure
The allotment of power distribution, and then inhibit the transmission of unstable vibration phenomenon.The result that the simulation test carried out by laboratory obtains
It proves, for the rubber damping gasket of the utility model compared with surface not the rubber damping gasket of open channels, effectiveness in vibration suppression is more excellent
It is different.
2nd, rubber damping gasket described in the utility model, base material can be bigger from any one damped coefficient,
(such as natural rubber, synthetic rubber such as nitrile rubber, butyl rubber) is chosen in the relatively good material of corresponding effectiveness in vibration suppression.Material
Simplicity is obtained, without carrying out complicated design to material mixture ratio.
3rd, the utility model is in rubber damping gasket surface by being provided with evenly arranged groove structure in a particular form,
And apply it in mechanical system, to cut down and inhibit unstable vibration.And without parts other in modernization system
Structure, equally need not newly-increased accessory.The channel away of gasket is simple in structure, easy to process, low manufacture cost, easily implements.
Description of the drawings
Fig. 1 a are the structure diagrams of the utility model embodiment one.
Fig. 1 b are the A-A sectional views of Fig. 1 a.
Fig. 2 is the structure diagram of the utility model embodiment two.
Fig. 3 is that rubber damping gasket is added without in analog mechanical system, adds in rubber damping of the surface without any change
The groove of gasket and addition this patent is parallel in the rubber damping gasket and groove of central axis with same angle tilt
After the rubber damping gasket of central axis, the time-domain signal comparison diagram of obtained system tangential vibrations acceleration (the 3rd in Fig. 3,

Specific embodiment
Embodiment 1
Fig. 1 a and 1b show that a kind of specific embodiment of the utility model is that rectangular rubber damping gasket surface is opened
There is the groove axisymmetricly arranged with central axis.It is mutually parallel between groove, and is parallel to the central axis.Institute is fluted
Width t all sames, the fluted depth all same of institute, the spacing all same between all two neighboring grooves, and all grooves
Run through rubber damping gasket upper surface.
Rubber damping gasket is rectangle, and the center line of at least one groove passes through the rectangular central point (i.e.
Two cornerwise intersection point of rectangle).Length of the flute length l of the groove for rectangular rubber damping gasket short side, the slot of groove
Wide t is the 1/10 of the long edge lengths of rectangular rubber damping gasket, and the depth h of groove is the 1/3 of rubber damping gasket integral thickness
Between~1/2.
Embodiment 2
It is rectangle Fig. 2 shows gasket, another specific embodiment of the utility model is the rubber damping pad
Piece surface is provided with several grooves that the central axis is favoured with equal angular.
Groove is 45 ° with damping gasket center line (or central axis) angulation β, and ditch groove deep h is in rubber damping
Between the 1/3~1/2 of gasket integral thickness.
The shape of above-mentioned rubber damping gasket can also be rectangular, round, oval or other geometries.
The groove described in the utility model for being arranged in rubber damping gasket surface in a particular form, number have no strictly
It is required that regardless of whether be booked the surface of entire damping gasket, the effect for inhibiting unstable vibration can be effectively promoted, as long as full
Sufficient arrangement form, only effectiveness in vibration suppression is best with embodiment 1,2.
Fig. 3 is that rubber damping gasket is added without in mechanical system, adds in rubber damping gasket of the surface without any change,
And add in this patent all grooves with same angle tilt in central axis and all grooves each parallel to center
After the rubber damping gasket of axis, the time-domain signal comparison diagram of tangential vibrations acceleration.It can be seen that：Compared to being added without rubber
Damping gasket, the unstable vibration phenomenon of system makes moderate progress after adding in rubber damping gasket of the surface without any change, and adds
Entering the vibration acceleration amplitude of system after the groove structure rubber damping gasket described in this patent becomes lower.Illustrate rubber pad
It is more preferable that piece surface is provided with the effectiveness in vibration suppression after groove.
