Background technology
Transmission belt is made up of relatively soft rubber or other high polymer materials, and belt driver is large span in itself
Structure, so oscillation crosswise undesirably can be produced during its work, not only create noise, and have impact on transmission
Precision, the fatigue wear of transmission belt is accelerated, so as to reduce the service life of band.Particularly in recent years, mechanical processing industry and
The fast development of auto industry, the stationarity of motor and its drive, quietness and accuracy are proposed higher
It is required that.Belt drive system in engine is the important transmission parts in automobile, and the quality of its work quality directly affects hair
Motivation and its vehicle traveling comfort.Santana maintenance center statistics display failure caused by transmission belt accounts for whole
The 15.9% of individual maintenance record, the root of belt failure is that vibration and heating cause aging and abrasion, therefore V belt translation vibration damping is ground
Study carefully and cause stream scholars' further investigation.
If a kind of V belt translation shock absorber has following functions：Can be by changing inherent parameters to belt transmission system
Tensioning regulation is carried out, major part can also be absorbed and cause the energy with vibration, and then vibration damping (has tensioning, inhaled to the band
The function of shaking), and outside need not provide energy, itself can by the use of absorbed cause the energy that band vibrates as itself
Input energy, this is by having certain application value with vibration damping.
The working media of magnetorheological bump leveller is magnetorheological materials, and its flow behavior can be sent out in the presence of externally-applied magnetic field
It is raw to change.When externally-applied magnetic field acts on magnetorheological materials, it will be converted into class solid-state properties by liquid characteristic；When externally-applied magnetic field disappears
During mistake, it can be converted rapidly from class solid-state to liquid.The size of so magnetorheological bump leveller damping force can pass through magnetic field
Change control.
The constitutive relation of magnetorheological materials generally represents that its formulation is with bingham's plasticity model：
τ in formula0(H) it is shear yield stress caused by externally-applied magnetic field；H is the magnetic field intensity of externally-applied magnetic field；η glues for plasticity
Degree, it is the ratio of shear yield stress and shear strain；For shear rate.
Utility model content
The technical problems to be solved in the utility model is to provide one kind can be by changing inherent parameters to V belt translation
System carries out tensioning regulation, can also absorb major part and cause the energy with vibration, and then vibration damping (has and opened to the band
Tightly, the function of absorbing), and the electric current that the energy of absorption is excited by the piezo-electric effect of piezoelectric vibrator can be changed externally-applied magnetic field
Intensity controls the rheological behavior of magnetorheological elastic fat, and then the intrinsic frequency for changing bump leveller itself carries out to belt transmission system
The V belt translation tensioning bump leveller of magnetorheological elastic fat shearing direct acting-shearing rotation of vibration damping.
In order to effectively realize that the V belt translation tensioning bump leveller of magnetorheological elastic fat shearing direct acting-shearing rotation is as described above
The advantages of, the utility model is realized as follows：The tensioning bump leveller is by housing, bayonet lock, tooth form sealing ring, sky
Gas compensator, piezoelectric vibrator, magnetorheological elastic fat, cage ring, magnet coil, piston, piston rod, sealing ring, shaft-cup, bolt,
Tensioning wheel forms.Housing, shaft-cup are bolted to form a chamber, and piston rod is connected with piston, piston rod and tensioning wheel
Revolute pair is formed by hinge, the gap between piston outer wall and inner walls with a 2mm, led between piston rod and shaft-cup
Cross sealing ring cooperation and cavity seal, magnetorheological elastic fat are riddled into this sealed chamber, compensated with air device is located in sealed chamber
On portion's housing inner bottom surface, piezoelectric vibrator is located at compensated with air device inwall, and piston is provided with groove, magnet coil around in this groove,
And magnet coil is isolated with magnetorheological elastic fat by cage ring；Housing is provided with axis hole and arc groove, and magnetorheological elastic fat is full of
Sealed in arc groove, and by tooth form sealing ring, bayonet lock forms sliding pair with arc groove, and neck arc end is provided with logical arc groove.
The V belt translation of magnetorheological elastic fat shearing direct acting-shearing rotation described in the utility model is tensioned the positive of bump leveller
Effect is：Because magnetorheological materials have the advantages of low of consuming energy, therefore the tensioning bump leveller introduces piezoelectric vibrator, by opening
The vibration of bearing up pulley drives the vibration of compensated with air device, because piezoelectric vibrator is arranged on compensated with air device inwall, and then drives piezoelectricity
The vibration of oscillator occurs piezo-electric effect generation electric current and causes magnetorheological elastic fat that rheological effect occurs, and the bump leveller realizes energy
From supplying functional.
