Technical field
The utility model relate to mechanical industry especially in heavy type, vehicle, mine, the vibrating machine as the helical compression metal spring (hereinafter to be referred as helical spring) of elastic element, particularly a kind of variable-pitch screw metal-rubber complex spring belongs to vibration and utilizes field of engineering technology.
Background technique
In the prior art, the pitch spiral compression spring such as generally adopt as elastic element in all conglomeraties such as heavy type, vehicle, mining machinery, the vibrating machine industry then generally pitch helical spring such as employing as main vibration spring or vibration-isolating spring.
Etc. the helical spring deformation under load characteristic curve of pitch is linear line, for waiting stiffness helix spring, and in some nonlinear engineering occasions, as vibrating conveyor, oscillating feeder, vibrating scalper, vibrating mill etc., because system load is all changing constantly under the motion state, a large amount of for a long time use etc. the pitch helical spring have the energy consumption height, technical problem such as efficient is low, noise is big, effect is not good.
In recent years, though the application report of non-linear variable-pitch screw spring is arranged, but still have that noise is big, bigger, the problems such as working life short, maintenance frequency height of noise are difficult to solve during doubling-up.
Summary of the invention
The purpose of this utility model provides a kind of variable-pitch screw metal-rubber complex spring, have simple in structure, absorbing is strong, noise is little, bearing capacity is big, become stiffness characteristics, spring silk working stress is little, the life-span long, characteristics such as corrosion-resistant, wear-resistant and explosion-proof, the problems referred to above that exist with the solution prior art.
The utility model variable-pitch screw metal-rubber complex spring is to take following technological scheme to realize: variable-pitch screw metal-rubber complex spring of the present invention is composited by variable-pitch screw metal spring and rubber adhesive two-part.The variable-pitch screw metal spring has rubber adhesive to constitute variable-pitch screw metal-rubber complex spring by a steel wire coil coiled variable-pitch screw metal spring in variable-pitch screw metal spring outside.Described rubber adhesive forms hollow or solid column structure, can be made into internal and external screw shape or interior outer cylindrical.
Described variable-pitch screw metal spring has the above effective helix angle of 3 circles at least, and to have the above effective pitch of 2 circles again at least be the spiral of different pitches.
The footpath equates in the spiral of the effective pitch of described variable-pitch screw metal spring, or the middle footpath of described effective pitch is along the axial change of described helix structure.
Described metal-rubber complex spring is with rubber layer clad metal spring inner and outer surface, forms certain thickness.
The deformation under load characteristic line of described variable-pitch screw metal spring is cumulative type non-linear line, and is continuous or piecewise continuous: this will help preventing the generation of its resonance and flutter; The size of pitch can be between each circle and gets different pitches, also can be several circles and is one group and get into several different pitches; Pitch can ascending unidirectional array, also can be by bi-directional arrangement broad in the middle small in ends.
The utility model is to coat spring by variable-pitch screw metal spring and rubber to be composited, and rubber adhesive adopts the synthetic cement of the natural gum more than 80 percent to be made.
Metal end plate can be equipped with in described variable-pitch screw metal-rubber complex spring two ends, to increase variable-pitch screw metal-rubber complex spring end face contact stiffness.
Owing to constitute the pitch variation of the helix structure of spring, add and have certain thickness rubber adhesive, make the present invention have significantly non-linear and required change stiffness characteristics, be that construction system rigidity has the change stiffness characteristics that increases and decreases with load, reach and make that system is effectively energy-conservation, the purpose of steady running.
The utility model is compared with rubber spring bigger rigidity, comparing with metal spring has bigger damping and amortization, so its effect is positive, obvious and unique: as to have simple in structure simultaneously, absorbing is strong, noise is little, bearing capacity is big, become stiffness characteristics, spring silk working stress is little, life-span is long, corrosion-resistant, characteristics such as wear-resistant and explosion-proof, be adapted to mining machinery especially, the suspension frame structure of heavy vehicle, super-huge vibrating machine such as super-huge vibromill, vibrating sieve, load such as oscillating feeder are used than the occasion of big and load change wider range, more adapt to and are used for the vibration isolation state.
