The damp rubber pillar, which is utilized to damp vibration and is characterized in large damp coefficient and strong restraint of formants, functions with the spiral steel spring outwardly wrapped with the damp rubber coating to overcome and eliminate the shortcomings of swing proliferation when the steel spring resonates, thereby greatly shortening the attenuation period of free vibration and having significant effects of vibration damping, vibrating isolation and noise reduction. The utility model provides mechanic equipments with stable and safe operation, rapid vehicle shutting down and convenient installation and employment.
Description
Technical field
The utility model relates to a kind of vibration damping and vibration isolation device that lowers and isolate the vibration that machinery produced, and especially relates to a kind of damping steel spring vibration damper, belongs to the environmental protection machinery field.
Background technique
There is the machinery of motion all can produce vibration, we can say that motion just has vibration.In most of the cases, the vibration of machinery is harmful to, if the fruit vibration problem solves badly, and machinery even can not use, for example the vibration problem of automobile, train solves badly, and personnel take and can not feel well, and vibration is too big even can't take.The noise that diesel vibration produces can make peripheral personnel feel very uncomfortable.The vibration of fixing machinery can make fixing body produce resonance, and surrounding enviroment are exerted an influence, and therefore, vibration damping and vibration isolation is the major subjects that reduces and eliminate harmful mechanical vibration.
The vibration damping and vibration isolation device that uses has multiple at present, use the earliest with most popular be the metal coil spring vibration damping equipment, but the scope of this device bearing load is bigger, and can bear bigger load, natural frequency is lower, and wide accommodation, thermal adaptability is better, the life-span is long, so using scope is very extensive, and its shortcoming is that damping constant is little, its damping constant is only below 0.008, therefore free vibration is very long decay time, flutter easily takes place, the vibration damping less stable, amplitude increases sharply when especially resonance taking place, so the vibrationproof vibration isolating effect is not ideal enough.For eliminating the above-mentioned shortcoming of metal coil spring vibration damping equipment, people have developed the damping steel spring vibration damping and vibration isolation device that various damping materials and metal coil spring combine, common damping steel spring vibration damping and vibration isolation device is on the top of metal coil spring or the bottom adds a damping rubber pad formation, this damping steel spring damping device structure is simple, can increase damping constant, its shortcoming is that the time of free vibration decay is still long, damping constant is still big inadequately, especially when big load, its shortcoming is more remarkable.The damping steel spring vibration damping equipment that has is by various materials at the outside of steel spring parcel one deck, for example: woollen blanket, glass wool, rubber etc. constitute as damping layer, though the damping steel spring vibration damping equipment of this structure is more much better than the damping vibration attenuation effect of rubber pad damping steel spring vibration damping equipment, but still there is a shortcoming, because the damping layer of this coating damping steel spring vibration damping equipment is under spring is in free state, be to be wrapped in the spring outer ring under the bigger situation of the spacing of Spring Steel Wire, when spring is subjected to the load compression, coating is sandwiched in the gap of Spring Steel Wire easily, and is subjected in the load repetitiousness vibration processes repetitiousness to be subjected to shear action and is damaged at spring.
It is CN87100223A that State Patent Office disclosed the patent No. on August 12nd, 1987, name is called: the patent of invention of " prestressed damping spring vibration-reducing apparatus ", this patent of invention utilizes prestressing force with the spring of preloading and the damping layer of doing up under the compressed state of spring, and makes spring keep the stress holding device that gives of this pressured state to form.The damping material of this invention damping layer is oil resistant such as cotton shape felt, cotton shape plastics or cotton shape wool felt and the cotton shape body that can not absorb oil, and the interior outside of the cotton shape felt of damping is coated with the wire gaze that shields.The advantage of this invention is unlikely being sandwiched between the spring thread of having improved damping constant and damping material because the protection of inside and outside layer wire gaze is arranged, and can not cut off to come off.The shortcoming and defect of this invention is that the main effect of vibration damping and vibration isolation is still worked by helical spring, damping material is also little to the raising of damping constant, still can not adapt to heavy load, the vibration damping and vibration isolation requirement of the low-frequency vibration that dither that high speed machine equipment is produced or heavy load, low-speed machinery equipment are produced, especially still there is bigger shortcoming in the free vibration requirement that still can not reduce rapidly decay time.
The innovation and creation content
The purpose of this utility model provides a kind of damping rubber post steel spring vibration damper, it is low to overcome and solve the damping constant that the metal coil spring vibration damping equipment exists, free vibration is long decay time, flutter easily takes place, the vibration damping poor stability, amplitude increases sharply when especially resonance taking place, the imperfect technical problem of vibrationproof vibration isolating effect.
For achieving the above object, the utility model adopts the damping rubber post steel spring vibration damping equipment design proposal that is made of jointly damping vibration attenuation rubber column and vibration damping metal coil spring.
Described damping rubber post steel spring vibration damping equipment main structure is two parts, and one is the metal spiral steel spring, mainly plays damping effect, keeps all metal spiral steel spring vibration-damping functions; Two are the damping vibration attenuation rubber column; rubber column is except that flexible good vibration-damping function; it is big also to have damping constant; it is strong that resonance peak is suppressed ability; cross resonance time weak point; free vibration is shortened dramatically decay time; overcome and eliminate the shortcoming that helical steel springs when resonance amplitude increases sharply; the two interosculates; complement each other; good springiness with helical steel springs vibration damper; natural frequency is hanged down the big two-fold advantage of damping constant with rubber shock absorber; the vibration damping and vibration isolation effect is obvious in the interfering frequency scope of broad, and solid-borne sound transmission is had tangible noise reduction, makes to the utlity model has significant outstanding vibration damping; vibration isolation; the effect of noise reduction; machinery is stable; stop rapidly; aspect environmental protection, demonstrate superior function, and reasonable in design; easy to install and use, be widely used in the vibration damping of mechanical equipment vibration; vibration isolation; the noise reduction place.
