Description
Technical field
The present invention relates to damping rubber pad design and application field more particularly to a kind of damping rubbers for preventing from tearing and deforming
Pad.
Background technique
Damping rubber pad has extremely wide application in fields such as Machine Design manufacture, automobile manufacture, industrial productions, with
Installation space, mounting stability, occupied space volume requirement are increasingly stringenter in the modern industry field, the design of damping rubber pad
There is also diversified forms for manufacture.The most common design of damping rubber pad and application structure form are upper metallic framework and lower metal bone
Frame, form of intermediate junctions are injection molded elastomer adhesion；Wherein metallic framework is furnished with threaded hole or external threaded up and down, because this kind subtracts
It shakes rubber mat design and manufacturing process is simple, compact-sized, manufacturing cost is low, be used widely on each field.But this kind
Damping rubber pad haves the defects that certain and drawback in practical application: since damping rubber pad upper and lower end faces are close to by the two of damping
End face, screw thread can generate twisting resistance, damping rubber after mounting one to damping rubber pad in axial rundown process to yielding rubber up and down
Directly there are the reaction of one " torsion " " internal force ", this internal force can generate " loosening " to screw thread in the vibration of actual environment
It influences；In addition under same aging condition, the damping rubber pad aging speed compared with noticeable effort is always existed than under natural conditions
(or under fair external force) at least 3 times fast, durability and the big heavy discount of stability.
Summary of the invention
In order to solve the above problem the present invention provides a kind of damping rubber pad for preventing from tearing and deforming, rubber can be effectively prevent
The torsional deflection of colloid, and the service life of damping rubber pad can be greatly prolonged.
To achieve the above object, the present invention is implemented with the following technical solutions:
A kind of damping rubber pad for preventing from tearing and deforming, including upper skeleton, lower skeleton；The upper skeleton includes pedestal, convex
Tooth, the lower skeleton include pedestal, double wedge；Axial concave-convex insertion connection, complementary space note between the upper skeleton and lower skeleton
Mould rubber.
The end of the double wedge of the upper skeleton is that the end of round or lower skeleton double wedge is round.
The double wedge of the upper skeleton is uniformly distributed on the circumference of pedestal, the quantity of the groove formed between double wedge and lower skeleton
Double wedge quantity is equal, and the double wedge of the lower skeleton is uniformly distributed on the circumference of pedestal.
Double wedge quantity on the upper skeleton is no less than 4, and the quantity of the double wedge on the lower skeleton is no less than 4.
The upper skeleton and lower skeleton is metallic framework.
Compared with prior art, the beneficial effects of the present invention are:
1) design form that the present invention is intersected using damping rubber pad upper skeleton with lower skeleton " bumps ", in installation damping rubber pad
During can effectively offset torsional moment, make damping rubber be hardly hit in use vibration other than outer masterpiece
With.
2) present invention compares traditional same type damping rubber pad during installing damping rubber pad, saves preparatory high pressure and compressed
Installation process is reduced to zero to a possibility that damping rubber pad damage by journey；And it is available manually, automatically or semi-automatically tool subtracts this
Shake rubber mat is installed, and assembling capacity and the traditional same type damping rubber pad of the brevity comparison of assembling process improve a lot.
3) the upper lower skeleton in the present invention can be completed in the way of hot investment casting, greatly reduce manufacturing cost, damping
The production and processing of rubber mat can cooperate injection mold to be produced using upper lower skeleton；Traditional same type damping rubber pad is compared to use
Service life and reliability greatly promote.
Detailed description of the invention

Fig. 2 is the cross-sectional view of Fig. 1.
Fig. 3 is upper and lower Skeleton assembly explosive view.
In figure: 1- upper skeleton, 2- yielding rubber, 3- lower skeleton, 4- double wedge.
Specific embodiment
It elaborates below with reference to embodiment to the present invention, but practical range of the invention is not limited only to following realities
Apply example.
As shown in Figure 1-Figure 3, a kind of damping rubber pad for preventing from tearing and deforming, including upper skeleton 1, lower skeleton 3；On described
Skeleton 1 includes pedestal, double wedge 4, and the lower skeleton 3 includes pedestal, double wedge 4；It is axial recessed between the upper skeleton 1 and lower skeleton 3
Convex insertion connection, complementary space injection molded elastomer.
The end of the double wedge 4 of the upper skeleton 1 is that the end of round or lower skeleton 3 double wedge 4 is round.It is circular
Center can be processed into cavity, and when being conducive to injection molded elastomer, infiltration of the liquid rubber between upper skeleton 1 and lower skeleton 3 makes to subtract
It is connected between shake rubber 2 and metallic framework more preferable.
Since the end of the double wedge 4 of a side skeleton is designed as circle, so that the upper lower skeleton of " bumps " interconnection is being turned round
Turn to be in point contact when stress, space structure freedom degree does not change and do not influence damping effect, tightens in upper lower skeleton screw thread
During, the cross-over design form between this " bumps " skeleton can effectively prevent the torsional deflection of rubber bodies, and can be big
The big service life for extending damping rubber pad, installation process also become simple and easy.
The double wedge 4 of the upper skeleton 1 is uniformly distributed on the circumference of pedestal, the quantity and sending down the fishbone of the groove formed between double wedge 4
4 quantity of double wedge of frame 3 is equal, and the double wedge 4 of the lower skeleton 3 is uniformly distributed on the circumference of pedestal.Double wedge 4 on upper lower skeleton with it is recessed
The position of slot is corresponding.
4 quantity of double wedge on the upper skeleton 1 is no less than 4, therefore " groove " quantity constituted is quite a few in 4,
The quantity of double wedge 4 on the lower skeleton 3 is no less than 4, and " groove " quantity equally constituted is quite a few in 4.
The upper skeleton 1 and lower skeleton 3 is metallic framework.
Hole is threaded in the axis center position of upper skeleton 1 or lower skeleton 3 or fixing bolt is used for the peace of damping rubber pad
Dress is fixed.
Circumferencial direction rotatable engagement gap between upper skeleton 1 " groove " and lower skeleton 3 " double wedge " are as follows: 0.3~1.5mm, it should
Fit clearance range can be easier to carry out injection molding.
Production method of the invention is:
1) upper skeleton 1 and lower skeleton 3 are processed by the way of hot investment casting；
2) upper skeleton 1 and lower skeleton 3 are placed in mold, the injection molded elastomer into mold.
In interspersed (" bumps insertion ") type of attachment, upper lower skeleton in radial rotation between upper lower skeleton axial direction of the invention
Turn direction and there is " mechanical hard limit ", and hard spacing place is point contact, " freedom degree " for not influencing damping.Damping rubber pad upper and lower side
Face metal installation section can effectively offset installation torsional moment in circle rotation direction, and damping rubber is prevented to be in big change for a long time
Shape stress and then the stability for extending damping rubber service life, enhancing damping rubber.
