Description
Technical field
The present invention relates to vibration control apparatus, in particular it relates to a kind of isolation mounting.On this basis, the invention still further relates to a kind of vibrosieve including described isolation mounting.
Background technology
Vibrosieve is a kind of material screening equipment being widely used, and is usually used in bituminous mixing plant, dry-mixed mortar plant, Machine-made Sand station etc..
It is illustrated in figure 1 the structural representation of a kind of conventional vibrosieve.This vibrosieve mainly includes sieve nest 1 and for installing the pedestal 2 of this sieve nest 1.Under power set (such as motor 3) drive, eccentric block (not shown) rotates and causes sieve nest 1 of reciprocating vibration along complicated space curve, thus screening materials carrying.
In screening process, in order to coordinate sieve nest 1 and the vibration displacement of pedestal 2, reduce the oscillating component active force to pedestal 2, it usually needs adopt support spring 4 to install on the base 2 by sieve nest 1, described support spring 4 such as metal spring and rubber spring simultaneously.Metal spring respectively conventional in traditional shaker as shown in Figures 2 and 3 and rubber spring structure schematic diagram.The contrast schematic diagram of respectively rigidity k and damping ratio ξ and the relation curve of displacement d of this metal spring and rubber spring shown in Fig. 4 and Fig. 5.It can be seen that along with displacement d changes, the rigidity k and damping ratio ξ of the two is held essentially constant, and metal spring has relatively low rigidity kmWith damping ratio ξm.By this support spring 4, it is possible to reduce the dynamic loading being transferred to pedestal 2, especially for the vibrosieve being applied to building station type work station, it is necessary to be arranged in steel structure frame, the vibration isolating effect supporting spring directly determines required frame strength.Therefore, the anti-vibration performance supporting spring is significant for manufacturing cost and production safety.
The effect of vibration isolation represents typically by transport T, and namely transport T is more little, and vibration isolating effect is more good.Transport T expression formula is:
Wherein, ξ is damping ratio, and f is excited frequency, fnFor the natural frequency of isolation mounting (as supported spring), this natural frequency meets:
Wherein, k is the rigidity supporting spring.
Fig. 6 show according to (1) formula draw in different damping than under ξ, vibration transmissibility T and frequency ratio f/fnRelation curve.
In conjunction with actual condition, in vibrosieve start-up course, along with excited frequency f is gradually increased, vibration transmissibility T is in first increasing the variation tendency subtracted afterwards.Specifically, when excited frequency f tends to and natural frequency fnTime equal, vibration transmissibility T increases, until excited frequency f and natural frequency fnEqual and resonate, now vibration transmissibility T reaches maximum, as shown in Fig. 6 medium wave peak.From Fig. 6 it can also be seen that in this stage, damping ratio ξ is more little, peak value is more high.Therefore, for metal spring, owing to its damping ratio ξ is less, during resonance, vibration transmissibility T is very big, brings bigger shock loading to pedestal.
When excited frequency f tends towards stability and makes vibrosieve normal operation, excited frequency f is held essentially constant.In order to ensure screening effect and vibration isolation efficiency, the natural frequency f of usual isolation mountingnShould in prescribed limit, even if frequency ratio f/fnFall into the support spring design shown in Fig. 6 to allow in interval.It can be seen that in this interval, damping ratio ξ is more little, frequency ratio f/fnMore big, vibration transmissibility T is more little.When excited frequency f is constant, rigidity k is more little, frequency ratio f/fnMore big, vibration transmissibility T is more little.Therefore, in conjunction with Fig. 4 and Fig. 5, owing to the damping ratio ξ and rigidity k of rubber spring are all relatively large, in this normal work stage, vibration isolating effect is substantially poor than metal spring.And the rigidity k of metal springmRigidity k less than rubber springr, the damping ratio ξ of metal springmDamping ratio ξ less than rubber springr, therefore, when normal operation, the transport of metal spring is less than the transport of rubber spring, and this is consistent with actual condition.
The stopping process of vibrosieve is similar to start-up course, and along with excited frequency f is gradually reduced, vibration transmissibility T is in first subtracting the variation tendency increased afterwards.For the metal spring that damping ratio ξ is relatively small, vibration transmissibility T during resonance, causes greater impact to pedestal.
To sum up analyze, although traditional metal spring when normal operation can vibration isolation preferably, but easily produce strong resonance in the vibrosieve start and stop stage；Although traditional rubber spring in the vibration isolation preferably of vibrosieve start and stop stage, but can then have relatively poor vibration isolating effect when normal operation.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.It should be appreciated that detailed description of the invention described herein is merely to illustrate and explains the present invention, it is not limited to the present invention.
In the present invention, when not making contrary explanation, the noun of locality of use typically refers to reference to upper and lower, left and right shown in the drawings such as " upper and lower, left and right "；It is inside and outside that " inside and outside " refers to relative to the profile of each parts itself.
With reference to shown in Fig. 1 and Fig. 6 to Fig. 8, the present invention provides a kind of isolation mounting, and this isolation mounting can be used in the multiple occasion needing isolation or the transmission of damping vibration energy.Typically, the isolation mounting of the present invention is used for active vibration isolation (also referred to as " power vibration isolation "), is namely used for reducing vibratory equipment by basis (such as pedestal) impact on surrounding.But the present invention is not limited to this, and the occasion that can be used for any suitable carries out vibration isolation.
The isolation mounting of the present invention includes first installation portion the 5, second installation portion 6 and is arranged on the buffer stopper 7 being made up of elastomeric material between this first installation portion 5 and second installation portion 6.Wherein, described first installation portion 5 and the one in described second installation portion 6 are for being connected with vibration source (sieve nest 1 such as vibrosieve), and another one is for being connected with pedestal 2.Further, the cross section (hereinafter referred to as " cross section ") from described first installation portion 5 to the direction of described second installation portion 6 that is perpendicular to of described buffer stopper 7 has different areas.
It should be noted that, direction from first installation portion the 5 to the second installation portion 6 of the present invention typically refers to the direction along shortest path therebetween, and this explanation is equally applicable to described from the first installation portion 5 to the direction of upper installation portion 6a and lower installation portion 6b subsequently.Such as, in the preferred implementation shown in Fig. 7, owing to the first installation portion 5 is respective with upper installation portion 6a for substantially planar with the surface that buffer stopper 7 contacts and parallel to each other, then the first installation portion 5 is the straight line being perpendicular to described plane to the shortest path of upper installation portion 6a, and this rectilinear direction is from the first installation portion 5 to the direction of upper installation portion 6a.Correspondingly, described cross section is parallel with described plane, and vertical with described rectilinear direction.Isolation mounting for other structures and form, it is possible to by same procedure by that analogy, is no longer described in further detail this.
In isolation mounting provided by the invention, based on above-mentioned basic embodiment, first installation portion the 5, second installation portion 6 and the quantity of buffer stopper 7, structure and the annexation etc. with vibration source and pedestal can make multiple different choice and design according to practical situation.This will be described in detail below in conjunction with the preferred embodiment of the present invention.
Pass through technique scheme, when amplitude is less (such as, normal work stage in vibrosieve), isolation mounting deforms and buffer shock-absorbing mainly through the part that buffer stopper 7 middle section is long-pending less, other parts of buffer stopper 7 then have relatively small deflection, so that the mean rigidity of buffer stopper 7 entirety and damping ratio are relatively small, vibration transmissibility T is relatively low, and vibration isolating effect is better.
When excited frequency f is close to even equal to natural frequency fnWhen amplitude is increased (such as; vibrosieve startup stage and the stage of shutdown), the deflection of the long-pending bigger part in buffer stopper 7 middle section of isolation mounting dramatically increases so that the damping action of buffer stopper 7 entirety increases; accelerate to consume vibrational energy, thus reducing vibration transmissibility T.
For ease of understanding, the deep layer principle that the present invention realizes the effect above below is further explained.
According to classical mechanics knowledge it can be seen that in vibration processes, the summation of the power suffered by each cross section of buffer stopper 7 is equal.But, owing on the direction from first installation portion the 5 to the second installation portion 6, the area of the cross section of various location is different, thus the size acting on power in unit are is also different.Thus so that the deflection of the part being on varying cross-section of buffer stopper 7 is different: the part deformation that sectional area is less is relatively big, and the part deformation that sectional area is bigger is less.
When amplitude is less, the deflection of the part that the sectional area of buffer stopper 7 is bigger is relatively small.Compared with traditional uiform section buffer stopper, the mean rigidity of buffer stopper 7 entirety in isolation mounting of the present invention and damping are smaller, it is thus possible to make vibration transmissibility T relatively low.
When amplitude is bigger (or in increase process), the deflection of the part that the sectional area of buffer stopper 7 is bigger can dramatically increase, and amplitude increment is more big, and the speedup of this part deformation is more obvious.Thus, the damping action of buffer stopper 7 entirety increases, and accelerates vibrational energy consumption, reduces vibration transmissibility T.
Be can be seen that by above analysis, compared with existing isolation mounting, isolation mounting provided by the invention can regulate according to amplitude variations for vibration damping, the damping of the buffer stopper of buffering and/or rigidity, thus all can keep good vibration isolating effect in resonance and normal work stage.
Further, since the rigidity of buffer stopper 7 and damping ratio are subject to the impact of many factors (such as material, structure), above description of the invention is not directed entirely to the relation curve shown in Fig. 6, but utilizes one more intuitive way to carry out principle analysis.Therefore, although the present invention is structurally relatively easy, but on prior art basis, obtains technical scheme remain a need for long-term practice and creative process of the test.
Just as described above, the structure of buffer stopper 7 by multiple choices, as long as its cross section has different areas, can belong to the concept of the present invention.Preferably, along the direction from first installation portion the 5 to the second installation portion 6, the cross-sectional area increasing or decreasing that the edge of described buffer stopper 7 is perpendicularly to the direction.Compared to other version, this preferred structure can make isolation mounting more stable, and is easy to manufacture and install.
With reference to Fig. 7 and Fig. 8, according in the isolation mounting of a kind of preferred implementation of the present invention, the second installation portion 6 includes installation portion 6a and lower installation portion 6b, and the first installation portion 5 is arranged on this between installation portion 6a and lower installation portion 6b.Buffer stopper 7 includes the upper buffer stopper 7a being arranged between described upper installation portion 6a and described first the installation portion 5 and lower buffer stopper 7b being arranged between described first installation portion 5 and described lower installation portion 6b, wherein, being perpendicular to of upper buffer stopper 7a has different areas from the first installation portion 5 to the cross section in the direction of upper installation portion 6a, and the cross section from the first installation portion 5 to the direction of lower installation portion 6b that is perpendicular to of lower buffer stopper 7b has different areas.
Preferably, for Stability Analysis of Structures, stable purpose is vibrated, it is possible to make described upper buffer stopper 7a and described lower buffer stopper 7b have identical structure and be symmetrically disposed in the both sides of the first installation portion 5.
Further, described upper buffer stopper 7a and described lower buffer stopper 7b respectively hemispherical buffer stopper or frustum buffer stopper, respectively as shown in Figure 7 and Figure 8.So, upper and lower buffer stopper 7a, 7b are each, near the part of the part on arc top or close frustum taper end, the part that sectional area is less, otherwise are then the part that sectional area is bigger.In vibration processes, this upper and lower buffer stopper 7a, 7b deformation when various amplitude meets the above-mentioned explanation for buffer stopper 7, therefore, explanation is not repeated.It should be appreciated that of the present invention hemispherical can be a hemispheroidal part, and should not be limited to the hemisphere on strict geometric meaning.
In the isolation mounting of the present invention, it is possible to select to make the first installation portion 5 or the second installation portion 6 be connected to vibration source (sieve nest 1 such as vibrosieve) or pedestal 2.When the first installation portion 5 is for being connected with vibration source, it is possible to make the arc top of described hemispherical buffer stopper or the taper end of described frustum buffer stopper towards this first installation portion 5.By this set, the part that the upper and lower respective sectional area of buffer stopper 7a, 7b is less directly bears vibration source effect, and vibration preferentially makes the part deformation that this sectional area is less.So that have less mean rigidity and damping ratio when amplitude is less, and when amplitude is bigger owing to effectively active force to be transferred to the part that sectional area is bigger by compression, it is thus possible to keep relatively low vibration transmissibility T preferably.It addition, this structure can also increase stability.
Additionally, in order to increase structural stability further, the isolation mounting of the present invention can also include the attachment structure 8 being fixedly connected on described upper installation portion 6a and lower installation portion 6b, to be made the relative position of described upper installation portion 6a and described lower installation portion 6b remain unchanged by this attachment structure.By arranging this attachment structure 8, additionally it is possible to make the isolation mounting of the present invention form independent product, this is easy to after damaging and losing efficacy to be replaced.
Can be formed by multiple suitable material for constituting one of the critical component of isolation mounting of the present invention buffer stopper 7 (including upper buffer stopper 7a and lower buffer stopper 7b), it is preferable that this buffer stopper 7 can be block rubber.
In isolation mounting according to a kind of comparatively preferred implementation of the present invention, buffer stopper 7 can have pre compressed magnitude.Having pre compressed magnitude by being set to, buffer stopper 7 can only contact with the first installation portion 5 and the second installation portion 6 and not be attached.Further, in vibration processes, this part pre compressed magnitude is it can be avoided that buffer stopper 7 separates with the first installation portion 5 and the second installation portion 6, thus all can play buffering, effectiveness in vibration suppression in reciprocating motion.
On this basis, the present invention also provides for a kind of vibrosieve, and this vibrosieve includes sieve nest 1 and for installing the pedestal 2 of this sieve nest 1, is additionally provided with described isolation mounting provided by the invention between described sieve nest 1 and described pedestal 2.Wherein, sieve nest 1 is connected to described first installation portion 5 as vibration source, and pedestal 2 is then connected to described second installation portion 6.
By isolation mounting provided by the invention, this vibrosieve all can by vibration isolation preferably in start and stop stage and course of normal operation, it is thus possible to effectively reduce the dynamic loading being transferred to pedestal 2, reduces the impact on surrounding.
The preferred embodiment of the present invention is described in detail above in association with accompanying drawing; but; the present invention is not limited to the detail in above-mentioned embodiment; in the technology concept of the present invention; technical scheme can being carried out multiple simple variant, these simple variant belong to protection scope of the present invention.
It is further to note that each the concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, it is possible to be combined by any suitable mode.In order to avoid unnecessary repetition, various possible compound modes are no longer illustrated by the present invention separately.
Additionally, can also carry out combination in any between the various different embodiment of the present invention, as long as it is without prejudice to the thought of the present invention, it should be considered as content disclosed in this invention equally.
