The electromagnetic field can heighten viscosity of magnetorheological fluid or magnetorheological grease inside the rotary magnetorheological damper, and increase damping force caused when the drive part and a driven part inside the adaptive magnetorheological clutch rotate relative to each other, thereby leading the drive part and the driven part inside the adaptive magnetorheological clutch to complete coupling to realize torque transmission.
Description
Technical field
The utility model belongs to a kind of magnetic clutch, is specifically related to a kind of self-adaptive magnetorheological clutch.
Background technique
The magnetic clutch that uses mainly contains at present: dry type monolithic magnetic clutch, dry-type multidisc electromagnetic clutch, wet type multi-disc electromagnetic clutch, magnetic powder clutch, slip type magnetic clutch etc.Their working state is such: when magnetic clutch is in jointing state, be in jointing state between the driving link of magnetic clutch and the driven member, the driving link band driven member and is rotated, thereby torque is transmitted, and when magnetic clutch is in separated state, be in separated state between driving link and the driven member, when driving link rotated, driven member was static; Since the joint of this class magnetic clutch with separate this two states and all will rely on the external control power supply to come coil to magnetic clutch to carry out power on/off to realize, so the working condition that this class magnetic clutch can not adapt to load automatically engages and separates.
Summary of the invention
The utility model engages and the deficiency of separating at the working condition that the common electrical magnet clutch can not adapt to load automatically, a kind of self-adaptive magnetorheological clutch has been proposed, the automatic joint that self-adaptive magnetorheological clutch can be realized magnetic rheological clutch according to the variation of prime mover and driven machine (that is: load) working condition with separate, for the transmission of torque between prime mover and driven machine provides a kind of relatively safety method.
The technical solution of the utility model is as follows:
A kind of self-adaptive magnetorheological clutch, it comprises generator and rotation MR damper, the driving link of self-adaptive magnetorheological clutch is by the field coil assembly of the rotor winding of generator and rotation MR damper or electromagnet constitutes and on same axle, the output terminal of the rotor winding of generator directly or by field coil or the magnet spool of rectifier control circuit with the rotation MR damper is connected, and the electric energy that generator is exported can be directly inputted in the field coil that rotates MR damper or the magnet spool and generate an electromagnetic field.
The function of self-adaptive magnetorheological clutch is achieved in that prime mover and driven machine is connected respectively on the driving link and driven member of self-adaptive magnetorheological clutch, when prime mover rotates, the rotor winding of generator on the self-adaptive magnetorheological clutch driving link and the field coil or the electromagnet rotation of rotation MR damper will be driven, the electric energy that the rotor winding of generator produces when rotated is input in the field coil assembly of rotation MR damper or the magnet spool directly or by rectifier control circuit it is generated an electromagnetic field, self-adaptive magnetorheological clutch is exactly to utilize this electromagnetic field that the viscosity of magnetic flow liquid or magneto-rheological grease in the rotation MR damper is uprised, damping force when making the driving link of self-adaptive magnetorheological clutch and driven member generation relative rotary motion increases, and the driving link that makes self-adaptive magnetorheological clutch is finished coupling with driven member and the realization transmission of torque.Because of the electric energy that generator sends relevant with the speed of generator amature winding cutting magnetic line, so, the high more electric energy that generator is sent of the rotating speed of prime mover is just big more, the electromagnetic field intensity that rotation field coil assembly of MR damper or electromagnet are produced is also just big more, make between the driving link of self-adaptive magnetorheological clutch and driven member coupling good more, make the self-adaptive magnetorheological clutch torque transmitted just big more.
When the start up period that prime mover operates in, also not reaching rated speed, because this moment, the rotating speed of generator was lower, the power delivery of sending is little to the electromagnetic field intensity that the self-adaptive magnetorheological clutch coil is produced, make the viscosity of magnetic flow liquid or magneto-rheological grease in the rotation MR damper not high, the damping force of driving link and driven member relative rotary motion is also little, so the driving link of self-adaptive magnetorheological clutch can't drive the driven member rotation; When prime mover finish start its rotating speed near or reach rated speed after, this moment, the rotating speed of generator was higher, the power delivery of sending is enough big to the electromagnetic field intensity that the self-adaptive magnetorheological clutch coil is produced, make the viscosity increased of magnetic flow liquid or magneto-rheological grease in the rotation MR damper, the damping force of driving link and driven member relative rotary motion is bigger, thereby the driving link that makes self-adaptive magnetorheological clutch can drive driven member to be rotated and outputting power, and driven function is run well; When the situation of driven machine overload takes place in self-adaptive magnetorheological clutch in the course of the work, because the rotating speed of prime mover operation is reduced, the electric energy that generator is sent reduces, the electromagnetic field intensity of the coil generation of self-adaptive magnetorheological clutch is reduced, the viscosity of magnetic flow liquid in the MR damper or magneto-rheological grease is reduced, the damping force of driving link and driven member relative rotary motion reduces, make the driving link of self-adaptive magnetorheological clutch can not drive the driven member rotation and produce idle running, thereby make the driven member of self-adaptive magnetorheological clutch stop outputting power; And in case after the releasing of this overload situations, prime mover can have been exported torque to driven machine by self-adaptive magnetorheological clutch again.Therefore, bonding force (square) can adapt automatically with the rotating speed that prime mover moves between the driving link of self-adaptive magnetorheological clutch and the driven member.Compare with the common electrical magnet clutch, self-adaptive magnetorheological clutch of the present utility model not only can be realized the soft start of load, and the joint that can also finish clutch in the working condition that does not have the manual intervention condition to go down automatically to adapt to load in when work with separate.
