V belt translation is tensioned bump leveller.
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.
The content of the invention
Can be by changing inherent parameters to belt transmission system the technical problem to be solved in the present invention is to provide one kind
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 the electric current that the energy of absorption is excited by the piezo-electric effect of piezoelectric vibrator can be changed applied field strengths
To control the rheological behavior of magnetorheological elastic fat, and then the intrinsic frequency for changing bump leveller itself carries out vibration damping to belt transmission system
Magnetorheological elastic fat shearing direct acting-flowing rotation V belt translation tensioning bump leveller.
In order to effectively realize that the V belt translation tensioning bump leveller of magnetorheological elastic fat shearing direct acting-flowing rotation is as described above
The advantages of, the present invention realizes as follows：The tensioning bump leveller is mended by housing, bayonet lock, tooth form sealing ring, air
Repay device, piezoelectric vibrator, magnetorheological elastic fat, cage ring, magnet coil, piston, piston rod, sealing ring, shaft-cup, bolt, tensioning
Wheel composition.Housing, shaft-cup are bolted to form a chamber, and piston rod is connected with piston, and piston rod passes through with tensioning wheel
Hinge forms revolute pair, has 2mm gap between piston outer wall and inner walls, by close between piston rod and shaft-cup
Seal coordinates riddles this sealed chamber by cavity seal, magnetorheological elastic fat, and compensated with air device is located at sealed chamber inner shell
On internal bottom surface, piezoelectric vibrator is located at compensated with air device inwall, and piston is provided with groove, and magnet coil leads to around in this groove
Cage ring is crossed to isolate magnet coil with magnetorheological elastic fat；Housing is provided with axis hole and arc groove, and magnetorheological elastic fat riddles arc
Groove, and sealed by tooth form sealing ring, bayonet lock forms sliding pair with arc groove, and logical arc groove is provided with the middle part of neck.
The good effect of the V belt translation tensioning bump leveller of magnetorheological elastic fat shearing direct acting-flowing rotation of the present invention
It is：Because magnetorheological materials have the advantages of low of consuming energy, therefore the tensioning bump leveller introduces piezoelectric vibrator, passes through tensioning wheel
Vibration drive the vibration of compensated with air device, because piezoelectric vibrator is arranged on compensated with air device inwall, and then drive piezoelectric vibrator
Vibration piezo-electric effect occur produce electric current to cause magnetorheological elastic fat that rheological effect occurs, the bump leveller realizes energy confession
Answer function.
Brief description of the drawings
Fig. 1 is the structural principle for the V belt translation tensioning bump leveller that the magnetorheological elastic fat of the present invention shears direct acting-flowing rotation
Schematic diagram.
