A central hole is reserved in the middle of the flange, a connecting block is arranged in the central hole, and at least two identical absorbing rubber parts used for connecting the flange and the connecting block and located between the flange and the connecting block are further arranged in the central hole. A mounting hole used for mounting an element is reserved in the middle of the connecting block. The central hole of the flange and the edge of the connecting block are both circular. Each absorbing rubber part is a section of a ring, and the absorbing rubber parts are evenly distributed along the ring. The element is mounted on the connecting block of the integrated rubber shock absorber, and the flange is mounted through screws. The absorbing rubber parts arranged between the connecting block and the inner wall of the flange are used for shock absorbing and are integrally mounted together, and the integrated rubber shock absorber is small in structural size, suitable for shock absorbing for small elements and convenient to mount.
Description
Technical field
The utility model relates to vibration damping equipment, especially a kind of integrated form rubber shock absorber that is applicable to small-sized components and parts vibration damping.
Background technique
Vibration damper is used to weaken vibration transmission, and vibration damper commonly used generally adopts the form of separated type, and a plurality of vibration dampers are formed vibration insulating system together, is used for the vibration damping of large-scale axle, equipment and component more.
The screw rigid joint is adopted in connecting between vibration damper commonly used and equipment, component, the basis usually, and load rating is 3N～10000N, and inherent circular frequency is low.These damper structure sizes are big, load rating is big, therefore are not suitable for the vibration damping of small-sized components and parts.
Summary of the invention
To the problems referred to above, the utility model provides a kind of integrated form rubber shock absorber that is applicable to small-sized components and parts vibration damping.
To achieve these goals, the technological scheme of the utility model employing is following:
A kind of integrated form rubber shock absorber; It is characterized in that, comprise flange, the middle part of this flange is provided with center hole; In this center hole, be provided with contiguous block; In this center hole, also be provided with between said flange and contiguous block, be used to connect the vibration isolation rubber body of said flange and contiguous block, the middle part of said contiguous block is provided with the mounting hole that is used for installation elements.
The center hole of said flange and the edge of said contiguous block all are circular, and said vibration isolation rubber body is a section of annular, and the number of this vibration isolation rubber body is identical at least two, and said vibration isolation rubber body evenly distributes along annular.
The good effect of the utility model:
On the contiguous block of integrated form rubber shock absorber, components and parts are installed, flange is installed through screw.The vibration isolation rubber body that employing is arranged between contiguous block and the flange inner wall carries out vibration damping, and the vibration isolation rubber body all is integrated being installed together, and integrated form rubber shock absorber structural volume is very little, is fit to the vibration damping of small-sized components and parts, and easy for installation.
The center hole of flange and the edge of contiguous block all are circular, and the vibration isolation rubber body is to be installed in a section of annular between flange and the contiguous block, and the number of vibration isolation rubber body is at least 2; Be preferably 3 and more than; The vibration isolation rubber body is uniformly distributed with according to annular, and the rigidity of all directions is basic identical, polarization phenomena can not occur; Natural frequency is high, is applicable to the vibration damping of the high-frequency small-sized components and parts of excitation.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A view of Fig. 1.
Embodiment
Below in conjunction with specific embodiment the utility model is done further explain.
As depicted in figs. 1 and 2; A kind of integrated form rubber shock absorber; Comprise flange 1, be provided with center hole, in this center hole, be provided with contiguous block 2 at the middle part of this flange 1; In this center hole, also be provided with the vibration isolation rubber body 3 that is used to connect said flange 1 and contiguous block 2, the middle part of contiguous block 2 is provided with the mounting hole that is used for installation elements.
The edge of the center hole of flange 1 and said contiguous block 2 all is circular, and vibration isolation rubber body 3 is a section of annular, and the number of this vibration isolation rubber body 3 is identical four, and these four vibration isolation rubber bodies 3 evenly distribute along annular.
The edge of the center hole of flange 1 and contiguous block 2 all is circular; Vibration isolation rubber body 3 is for being installed in a section of annular between flange 1 and the contiguous block 2, and the number of vibration isolation rubber body 3 is four, and is uniformly distributed with according to annular; The load rating of vibration damper is little; All directions rigidity is basic identical, and natural frequency is high, is highly suitable for the vibration damping of the higher small-sized components and parts of energizing frequency.
Regulate the natural frequency of this integrated form rubber shock absorber if desired, the material that only needs to regulate arc length, width, the height of vibration isolation rubber body 3 or change vibration isolation rubber body itself gets final product.
Embodiment:
Contain many crystal oscillators in a certain product, these crystal oscillator natural frequencys are about 10kHz, and quality is about 2g.Because the natural frequency between the crystal oscillator differs very little, when crystal oscillator rigid joint together the time, produce resonance because frequency is approaching between the crystal oscillator, influence the crystal oscillator performance of products.
For vibration damping, in the product of a plurality of crystal oscillators, add an integrated form rubber shock absorber between each crystal oscillator and the mounting structure, the vibration damper size is not more than φ 30mm * 5mm, and natural frequencies is as shown in table 1,
Table 1:
Calculate according to the vibration isolation efficiency formula, this vibration damper damping efficiency is about E=1-(1/ ((10000/1803)
2-1))=0.97, therefore, this vibration damper can cut between a plurality of crystal oscillators 97% transfer of vibration, and effectiveness in vibration suppression is good.
The foregoing description of the utility model only is to give an example for what explanation the utility model was done, and is not to be the qualification to the mode of execution of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation and changes.Here can't give exhaustive to all mode of executions.Conspicuous variation that every technological scheme that belongs to the utility model is amplified out or change still are in the row of the protection domain of the utility model.
