Description
Technical field
The present invention relates to a kind of vibration control technology, especially can possess the spring vibration isolation device of damping capacity.
Background technique
So-called spring vibration isolation device refers to the elastic element between equipment and supporting structure, and this elastic element is processed by helical steel springs and consisted of, and is intended to reduce from this equipment to supporting structure or from supporting structure to this equipment transmitting vibrations or impact force.Hundreds of tons equipment can be used the spring vibration isolation device to light and handy precision type instrument from weighing, its advantage is: static deflection is large, natural frequency is low, low frequency vibration isolation is good, the erosions such as tolerance oil, water and solvent, be not acted upon by temperature changes, can not wear out or creep, characteristic variations is very little when producing in a large number.But it also has serious shortcoming simultaneously: own damping minimum (damping ratio about 0.005), and transmissibility is very large when consequently resonating, and easily along the steel wire transmitting vibrations, steel material itself is easy passing noise also, produces easily oscillating motion during high frequency.
The major advantage of rubber damper is the obstruct with high-frequency structure vibration, and shock resistance and sound insulation property can satisfy the requirement of Rigidity and strength.Rubber has interior friction, and critical damping is larger, and the therefore such strong resonance of rare steel spring can absorbing vibrational energy, and the vibrating machine that rubber damper is installed also can safe use by resonance region the time, can not produce excessive vibration.
Thereby, often consider to form the damping spring vibration isolator that is added external damping, sound insulationg board and inert block by helical steel springs.But, in practice more damping spring vibration isolator often at the upper and lower section's spring-rubber vibration isolating pad that arranges of helical steel springs to intercept noise transfer and to improve damping ratio, but, what form is spring and the connecting of rubber, helical steel springs is not produced damper restriction, no doubt be conducive to improve the overall vibration isolating effect of vibration isolator and sound insulation property, still, damping ratio that can't the Effective Raise vibration isolator.
Summary of the invention
Defective for the damping ratio deficiency that overcomes existing damping spring vibration isolator, the invention provides a kind of damping spring vibration isolator, this damping spring vibration isolator has not only kept the helical steel springs natural frequency low, the advantage that low frequency vibration isolation is good, and has a higher damping ratio, vibration isolation efficiency is high, and is simple in structure.
The technical solution adopted for the present invention to solve the technical problems is: a kind of damping spring vibration isolator is linked in sequence by damping sound insulation base, helical steel springs, upper force-bearing piece, level height adjustment bolt, rubber vibration isolation lid, support fixing bolt.The integral type damping sound insulation base of being made by rubber bottom plate and cylindrical shape rubber rubber, cylindrical shape rubber hits exactly at rubber bottom plate, it is Spielpassung between the internal diameter of the external diameter of helical steel springs and cylindrical shape rubber, helical steel springs is installed in the endoporus of cylindrical shape rubber, and the height of cylindrical shape rubber is 1/2 of helical steel springs height.The damping spring vibration isolator is that pressure-bearing is stressed, and rubber bottom plate replaces the steel base plate of existing damping spring vibration isolator, can avoid vibration by the base plate transmission.When the damping spring vibration isolator bore the equipment dynamic load, the helical steel springs height reduced, enlarged-diameter, and direct and cylindrical shape rubber rubber wall produces frictional force, and rubber improves the damping ratio of damping spring vibration isolator thus to the generation of vibration restriction of helical steel springs.Force-bearing piece on the integral type steel of being made by lower cylinder, upper cylinder, lower cylinder is installed in the endoporus of helical steel springs, and upper cylinder is installed in the top of helical steel springs, and upper cylinder is installed the rubber vibration isolation lid outward.Can avoid vibration by upper cylinder transmission.The rubber vibration isolation lid is to be made by straight cylinder shape rubber, the rubber flat plate center arranges internal diameter is adjusted bolt greater than level height circular port, the interior clear height of straight circular portion is the height of force-bearing piece and helical steel springs end circle, is transition fit between the internal diameter of straight circular portion and the external diameter of force-bearing piece and helical steel springs.Force-bearing piece and helical steel springs can be formed integral body by the rubber vibration isolation lid, be convenient to transport and install and use.The bolt hole that arranges in the middle of the upper force-bearing piece is installed adjusting screw rod, level height is installed respectively on the screw rod adjusts bolt, support fixing bolt.When the horizontal Height Adjustment bolt of rotation, just can adjust easily the height of spring vibration isolation device, adjust thus levelness and the stress balance of equipment support.The equipment support is fixed on level height and adjusts between bolt top and the support fixing bolt, and rubber washer and steel plate packing ring are set between equipment support and the support fixing bolt.The rubber bottom plate center of damping sound insulation base arranges circular port, and the base fixed bolt hole is set all around, and the bottom arranges anti-slip tank, and damping sound insulation base uses bolt to be installed on the terrace., when using, the environment of humidity ponding can be discharged by circular port and anti-slip tank, to prevent that ponding is on the helical steel springs impact in working life such as the damping spring vibration isolator.
The invention has the beneficial effects as follows that this product structure is simple and reliable, easy for installation, be applicable to active vibration isolation and the passive vibration isolation of various kinds of equipment.Can satisfy the transmission that intercepts vibration, damping ratio is high, and is simple in structure, can adjust as required the height of spring vibration isolation device simultaneously.
