Description
Technical field
The utility model relates to a kind of vibration control technology, especially can possess the belleville spring vibration isolator of damping capacity.
Background technique
The steel coil springs vibration isolator is widely used a kind of steel vibration isolator.Its advantage is: static deflection is large, and natural frequency is low, and the low frequency vibration isolation performance is good; Can tolerate the erosions such as oil, water, temperature variation does not affect performance; Can not wear out, creep does not occur.Shortcoming is: damping own is very little, transmits larger than very when resonance; Steel wire meeting transmitting vibrations during high frequency: produce easily oscillating motion.
Belleville spring is the gasket type spring with metal blank or the truncated cone shape cross section that forms of forging and pressing blank.Belleville spring is tapered in the axial direction and bears the special spring of load, after bearing load deformation, saves certain potential energy, and when relaxing appearred in bolt, belleville spring release portion potential energy was to keep the pressure between the flange connection to reach seal request.The belleville spring stress distribution is evenly successively decreased from inside to outside, can realize the effect of the low high equilibrant force of stroke.The advantage of belleville spring is: rigidity is large, and the buffering vibration absorption ability is strong, can bear large load with small deformation, is suitable for the little occasion of axial space requirement; Have the change stiffness characteristics, this spring has the nonlinear characteristics of very wide scope; Adopt different compound modes with same belleville spring, spring performance is in very large range changed, can adopt involutory, superimposed compound mode, also can adopt compound different-thickness, the compound mode of different sheet numbers etc.When superimposed, with respect to same distortion, spring number more at most load is larger.
Belleville spring absorbing performance is not less than cylindrically coiled spring, when adopting superimposed combination owing to the friction between the dish reed has larger damping, the dissipation impact energy.Belleville spring is widely used in the fields such as machinery industry, petroleum industry, automotive industry and aerospace industry owing to the stiffness characteristics of change is arranged and the characteristics such as compact are installed, and has replaced cylindrical helical spring very on a large scale.
Summary of the invention
In order to overcome the defective of existing damping spring vibration isolator, the utility model provides a kind of belleville spring vibration isolator, this belleville spring vibration isolator has not only kept the helical steel springs natural frequency low, the advantage that low frequency vibration isolation is good, and having highly lowly, bearing capacity is large, has higher damping ratio, vibration isolation efficiency is high, and is simple in structure.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of belleville spring vibration isolator is linked in sequence by steel positioning seat, cylindrical shape rubber, belleville spring group, adjustment installation component.The steel positioning seat is comprised of integral type rectangular steel plate and cylindrical shape setting sleeve, and the cylindrical shape setting sleeve is in rectangular steel plate center, and rectangular steel plate two limits arrange fixed bolt hole, and the bottom arranges anti-skid rubber cushion.Cylindrical shape rubber is installed in the cylindrical shape setting sleeve, is transition fit between the external diameter of cylindrical shape rubber and the cylindrical shape setting sleeve internal diameter.Belleville spring has small deformation high bearing capacity, joint space-efficient advantage.If the amount of deformation of monolithic belleville spring and bearing load value can not meet the demands, adopt as required involutory, superimposed compound mode, can obtain desirable loading characteristic.The belleville spring of superimposed use is because of two surface of contact, and because of the different frictional force that produce of distance of deformational displacement, frictional force has consumed energy, has played the damping effect.The belleville spring group forms by the multi-disc belleville spring is compound, and the belleville spring group is installed in the endoporus of cylindrical shape rubber, is Spielpassung between belleville spring group external diameter and the cylindrical shape rubber inside diameter.Prevent the belleville spring group when bearing the equipment dynamic load, produce dislocation.Adjust installation component by force-bearing piece and adjust that screw rod, level height are adjusted bolt, the support fixing bolt consists of, force-bearing piece is the steel column type, the centre arranges the bolt hole of adjusting screw rod, force-bearing piece is placed on the top of cylindrical shape rubber and belleville spring group, is Spielpassung between force-bearing piece external diameter and the cylindrical shape rubber inside diameter.Level height is adjusted bolt and is installed between force-bearing piece and the equipment support, the support fixing bolt is on the top of adjusting screw rod, the equipment support is fixed on level height and adjusts between bolt and the support fixing bolt, and rubber washer and steel plate packing ring are set between equipment support and the support fixing bolt.When the horizontal Height Adjustment bolt of rotation, just can adjust easily levelness and the stress balance of equipment support.
The beneficial effects of the utility model are, this product structure is simple and reliable, easy for installation, are particularly useful for the vibration and noise reducing of the various kinds of equipment pressure-bearing that the vibration isolator height is restricted.Can satisfy the transmission that intercepts vibration, damping ratio is high, and highly low, bearing capacity is large, can adjust as required the levelness height of finishing equipment support simultaneously.
