Put, in order to when whole mechanical system carries out operation, reduce external vibration source and the vibration produced by itself is produced to it
Raw influence, so that the running precision and response speed of mechanical system are reduced, but in most of mechanical system operations, its vibration
Source is all random, that is, the vibration form of expression of whole system is the flexibility unit in random vibration, particularly servomechanism
Part, its response to additional useless power is more obvious, therefore with the effect of vibration is amplified, if additional nothing was exerted oneself with the cycle
Property, then when power frequency close to system intrinsic frequency when can send out be resonance, can finally cause serious consequence, endanger
The person and property safety, therefore as needing an integrated controllable vibration damping inside above-mentioned heavy duty, high accuracy, fast corresponding mechanical system
Subsystem is significant, and because magneto-rheological grease has the yield stress and resistance to settling higher than magnetic flow liquid, and it has phase
Answer that speed is fast, reversible change, the features such as consume energy low, environmentally friendly, therefore the magnetorheological materials that the utility model is applied are magnetorheological
Fat.
Magneto-rheological grease is utilized under magnetic fields, and aligning occurs in magnetic particle so that the rheology of fat is special
Property, particularly its apparent viscosity, the principle work for significantly changing.Generally magneto-rheological grease is by micron order iron
Magnetic-particle, base fat, additive composition.Under the conditions of zero magnetic field intensity, the initial viscosity of magneto-rheological grease is larger.Research shows magnetic
The yield stress of rheology fat can reach the MP orders of magnitude, and between -40 DEG C -150 DEG C, the reversible of magnetic flow liquid follows operating temperature range
Ring change frequency is about 3,000,000 times, therefore, the vibration absorber based on magnetic rheology effect has long lifespan, is swift in response, works
The features such as temperature range is wide.
Utility model content
The technical problems to be solved in the utility model is to provide extrusion pressing type magneto-rheological grease load flex rotor shock absorber high, and this subtracts
The device that shakes is mainly used in the radial vibration-reducing of high capacity flex rotor, grows, is swift in response with life, the features such as operating temperature range is wide,
And shock absorber internal stability is good (magneto-rheological grease has the sedimentation stability higher than magnetic flow liquid).
In order to effectively realize vibration-damping function as described above, the utility model is realized as follows：The dress
Put mainly by chamber shell, magneto-rheological grease, magnet coil, platen, sealing ring, depression bar, rolling bearing, flex rotor composition.Chamber shell
Both sides are respectively provided with an annular groove, and magnet coil is arranged on inside two annular grooves, and platen is full of with chamber shell composition seal cavity, magneto-rheological grease
In this seal cavity, and magnet coil is isolated with magneto-rheological grease by sealing ring, platen and depression bar are connected, depression bar with roll
Bearing outer ring and flex rotor distinguish interference fit with rolling bearing inner ring, and chamber shell, platen are permeability magnetic material, and remaining is equal
It is non-magnet material.
The good effect that extrusion pressing type magneto-rheological grease described in the utility model is high to carry flex rotor shock absorber is：By magnetic current
Become this intellectual material of fat and apply to vibration absorber, be mainly used in the radial vibration-reducing of high capacity flex rotor, due to magneto-rheological grease
Can be transported with the sedimentation stability and bigger yield stress higher than magnetic flow liquid, therefore the shock absorber based on magneto-rheological grease
For bigger workload occasion, and its job stability is more preferably, and with reversible change, fast response time, consume energy low, work
Make temperature range it is wide, it is pollution-free the features such as.
Brief description of the drawings
Fig. 1 is the extrusion pressing type magneto-rheological grease internal structure schematic diagram for carrying flex rotor shock absorber high.
Fig. 2 is the extrusion pressing type magneto-rheological grease kinetic model for carrying flex rotor shock absorber high.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
In Fig. 1, the utility model extrusion pressing type magneto-rheological grease flex rotor shock absorber that carries high is mainly by chamber shell 1, magnetic current
Become fat 2, magnet coil 3, platen 4, sealing ring 5, depression bar 6, rolling bearing 7, flex rotor 8 to constitute.The both sides of chamber shell 1 are respectively provided with one
Annular groove, magnet coil 3 is arranged on inside two annular grooves, and platen 4 constitutes seal cavity with chamber shell 1, and magneto-rheological grease 2 riddles this sealing
Cavity, and magnet coil 3 being isolated with magneto-rheological grease 2 by sealing ring 5, platen 4 is connected with depression bar 6, depression bar 6 and the axis of rolling
Hold 7 outer rings and flex rotor 8 and distinguish interference fit with the inner ring of rolling bearing 7, chamber shell 1, platen 4 are permeability magnetic material, remaining
Be non-magnet material.
When magnet coil logical 3 enters a certain size electric current, the magnetic field 9 of some strength is produced in the place space of magneto-rheological grease 2,
There is rheological phenomena in magneto-rheological grease 2, so that with certain extruding yield force, the vibration that external vibration source produces is turned by flexible
Son 8, rolling bearing 7, depression bar 6 are driven inside the incoming shock absorber of platen 4, so that extruding magneto-rheological grease 2 absorbs mechanical system vibration,
Finally cause the operation of the held stationary of flex rotor 8.Because the extrusion application of magneto-rheological grease 2 can have more the intensity of externally-applied magnetic field 9
Change and change, with controllability, therefore, the shock absorber can join according to external vibration situation regulating system itself in real time
Number, with dynamic adaptivity.
In fig. 2, the utility model extrusion pressing type magneto-rheological grease kinetic model for carrying flex rotor shock absorber high.M in figure1
The quality of flex rotor 8, k1It is the rigidity of flex rotor 8, m2It is the quality of shock absorber, k2It is the rigidity of shock absorber, C is vibration damping
The damped coefficient of device, acts on the exciting force of flex rotor 8 for Psinwt, response of the flex rotor 8 under exciting force effect
It is x1, mechanical system is internally integrated shock absorber, as the intrinsic frequency w of regulation shock absorbern() be allowed to close to exciting force
Excited frequency, the now produced response x on flex rotor 8 of exciting force1X is responded by shock absorber2Absorbed, shock absorber is consolidated
There is frequency wnAbsorb more closer to the excited frequency of exciting force, work as wnDuring=w, the produced sound on flex rotor 8 of exciting force
Answer x1X is responded by shock absorber2(perfect condition) is fully absorbed, this is shock absorber kinetic parameter principle.
