Abstract
A combined mechanical damper is used for shock absorption of mechanical equipment and comprises a spring, a rubber washer and an idle block. One end of the spring is fixed on the rubber washer while the other end of the spring is fixed with the idle block. The lower layer of the combined damper is subjected to damping through the rubber washer while the upper layer of the combined damper is subjected to damping through the spring, thereby making good use of the advantages of the two damping modes while avoiding the shortcomings thereof. Low-frequency vibration of the mechanical equipment can be reduced by the spring, high-frequency vibration of the mechanical equipment can be reduced by the rubber washer, the spring and the rubber washer both have soundproof and buffering effects, and accordingly the damper formed by combining the spring with the rubber washer is better in shock absorption effect.
Description
Technical field
The utility model relates to mechanical damper.
Background technique
Machinery is in operation and can produces vibrations, and the damping modes in the tradition has spring shock absorption and rubber shock-absorbing, and spring cushion has good springiness, advantages such as stable mechanical property, and oil resistant dirt, high temperature resistant, but transmit dither easily; Rubber shock absorber is easy to process, but can only be used for every dither, and not oil resistant dirt, high temperature.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of compound mechanical damper, the low-frequency vibration that utilizes spring to lower machinery utilizes rubber can lower the dither of machinery, and the sound insulation impact of easing up is all arranged, after the associating of spring and rubber, damping effect is better.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of compound mechanical damper, be used for the machinery damping, and comprise spring, rubber pad, inert block, described spring one end is fixed on the rubber pad, and the other end and described inert block are fixed.The lower floor of compound vibration damper is the rubber pad damping, and the upper strata is a spring shock absorption, utilizes mutual advantage and avoids each other shortcoming.The low-frequency vibration that utilizes spring to lower machinery utilizes rubber can lower the dither of machinery, and the sound insulation impact of easing up is all arranged, and after the associating of spring and rubber, damping effect is better.
As improvement, can be that spring and the big rubber pad more than three united as damping; Or be provided with spring more than three, and rubber pad is the small rubber pad, and the quantity of described small rubber pad is identical with number of springs, and the corresponding small rubber pad of spring is united as damping.
As improvement, described inert block both sides are provided with mounting ear, described spring by screw on described mounting ear; Described spring is connected an end and is provided with slug with rubber pad, described spring is welded on the described slug, and described slug is fixedlyed connected with described rubber pad by screw.
As improvement, described inert block is down trapezoidal and is that reinforcing bar mixes earth, and concrete grade should be not less than C18 number, and its weight should be 2 ~ 5 times of equipment, and the planar central that should make every effort to make the center of gravity of equipment unit and each annex and inert block is on same vertical line.After reaching above-mentioned requirements, can obtain an extraordinary vibration damping, noise reduction effect facts have proved and vibrates to external world and can reduce more than 97% by vibration damping processing back machinery.
The beneficial effect that the utility model is compared with prior art brought is:
The low-frequency vibration that utilizes spring to lower machinery utilizes rubber can lower the dither of machinery, and the sound insulation impact of easing up is all arranged, and after the associating of spring and rubber, damping effect is better; Select for use reinforcing bar to mix earth as the inert block of support equipment, concrete grade should be not less than C18 number, and its weight should be 2 ~ 5 times of equipment, and the planar central that should make every effort to make the center of gravity of equipment unit and each annex and inert block is on same vertical line.After reaching above-mentioned requirements, can obtain an extraordinary vibration damping, noise reduction effect facts have proved and vibrates to external world and can reduce more than 97% by vibration damping processing back machinery.
