Description

The V belt translation tensioning bump leveller of magnetorheological elastic fat flowing direct acting-flowing rotation
Technical field
The present invention relates to V belt translation to be tensioned bump leveller, flows direct acting-flowing rotation more particularly, to magnetorheological elastic fat 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 flowing 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 flowing 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, and piston internal piston is provided with 2mm groove, and piston outer wall forms prismatic pair with inner walls, living Coordinated between stopper rod and shaft-cup by sealing ring and cavity seal, magnetorheological elastic fat are riddled into this sealed chamber, compensated with air Device is located on sealed chamber inner shell inner bottom surface, and piezoelectric vibrator is located at compensated with air device inwall, and piston is provided with groove, electromagnetic wire Circle isolates magnet coil with magnetorheological elastic fat around in this groove, and by cage ring；Housing is provided with axis hole and arc groove, magnetic Rheology elasticity fat riddles arc groove, and is sealed by tooth form sealing ring, and bayonet lock forms sliding pair with arc groove, is provided with the middle part of neck logical Arc groove.
The good effect of the V belt translation tensioning bump leveller of magnetorheological elastic fat flowing 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 flows direct acting-flowing rotation Schematic diagram.
Embodiment
The present invention is described in more detail with reference to the accompanying drawings and examples.
In Fig. 1, the V belt translation tensioning bump leveller of the magnetorheological elastic fat flowing direct acting-flowing rotation of the present invention, the tensioning is inhaled The device that shakes be by housing 1, bayonet lock 3, tooth form sealing ring 4, compensated with air device 6, piezoelectric vibrator 7, magnetorheological elastic fat 8, cage ring 9, Magnet coil 10, piston 11, piston rod 13, sealing ring 14, shaft-cup 15, bolt 16, tensioning wheel 18 form.Housing 1, shaft-cup 15 are logical Cross the connection of bolt 16 and form a chamber, piston rod 13 is connected with piston 11, and piston rod 13 passes through the shape of hinge 17 with tensioning wheel 18 Into revolute pair, 2mm groove is provided with inside piston 11, the outer wall of piston 11 forms prismatic pair, piston rod 13 with the inwall of housing 1 Coordinated between shaft-cup 15 by sealing ring 14 by cavity seal, magnetorheological elastic fat 8 riddles this sealed chamber, compensated with air Device 6 is located on the inner bottom surface of sealed chamber inner shell 1, and piezoelectric vibrator 7 is located at the inwall of compensated with air device 6, and piston 11 is provided with groove, Magnet coil 10 isolates magnet coil 10 with magnetorheological elastic fat 8 around in this groove, and by cage ring 9；Housing 1 is provided with Axis hole 2 and arc groove, magnetorheological elastic fat 8 riddles arc groove, and is sealed by tooth form sealing ring 4, and bayonet lock 3 is formed with arc groove and slided Pair, the middle part of neck 3 are provided with logical arc groove 5.
