Background technology
The electromagnetic clutch that uses mainly contains at present: dry type monolithic electromagnetic clutch, dry-type multidisc electromagnetic clutch, wet type multi-disc electromagnetic clutch, magnetic powder cluth, slip type electromagnetic clutch etc.Their operating state is such: when electromagnetic clutch is in engagement state, be in engagement state between the driving link of electromagnetic clutch and the driven member, the driving link band driven member and is rotated, thereby torque is transmitted, and when electromagnetic clutch is in released state, be in released state between driving link and the driven member, when driving link rotated, driven member was static; Since the joint of this class electromagnetic clutch with separate this two states and all will rely on the external control power supply to come coil to electromagnetic clutch to carry out power on/off to realize, so the working condition that this class electromagnetic clutch can not adapt to load automatically engages and separates.
Summary of the invention
The present invention is directed to the working condition that the common electrical magnet clutch can not adapt to load automatically engages and the deficiency of separating, a kind of self-adaptive electromagnetic clutch has been proposed, the automatic joint that self-adaptive electromagnetic clutch can be realized clutch according to the working condition of prime mover and driven machine (that is: load) with separate, for the transmission of torque between prime mover and driven machine provides a kind of relatively solution of safety.
Technical scheme of the present invention is as follows:
Self-adaptive electromagnetic clutch is to be made of generator and electromagnetic clutch, the driving link of its self-adaptive electromagnetic clutch is by the coil of the rotor winding of generator and electromagnetic clutch or coil block constitutes and on same axle, the electric energy output end of the rotor winding of generator directly or by rectifier control circuit is connected with the coil of electromagnetic clutch, and the electric energy that generator is exported can be directly inputted in the coil of electromagnetic clutch and it is generated an electromagnetic field.
The function of self-adaptive electromagnetic clutch is achieved in that prime mover and driven machine is connected respectively on the driving link and driven member of self-adaptive electromagnetic clutch, when prime mover rotates, the coil or the coil block rotation of the rotor winding and the electromagnetic clutch of generator on the self-adaptive electromagnetic clutch driving link will be driven, the electric energy that the rotor winding of generator produces when rotated directly or be input to by rectifier control circuit in the coil of self-adaptive electromagnetic clutch it is generated an electromagnetic field, self-adaptive electromagnetic clutch utilizes this electromagnetic field to make the driving link of self-adaptive electromagnetic clutch and driven member finish coupling and 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 the coil of self-adaptive electromagnetic clutch is produced is also just big more, make between the driving link of self-adaptive electromagnetic clutch and driven member coupling good more, make the self-adaptive electromagnetic clutch torque transmitted just big more.
When the startup stage 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 big inadequately to the electromagnetic field intensity that the self-adaptive electromagnetic clutch coil is produced, thereby the driving link of self-adaptive electromagnetic 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 electromagnetic clutch coil is produced, thereby the driving link that makes self-adaptive electromagnetic 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 electromagnetic 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 electromagnetic clutch is reduced, make the driving link of self-adaptive electromagnetic clutch can not drive the driven member rotation and produce idle running, thereby make the driven member of self-adaptive electromagnetic 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 electromagnetic clutch again.Therefore, bonding force (square) can adapt automatically with the rotating speed that prime mover moves between the driving link of self-adaptive electromagnetic clutch and the driven member.Compare with the common electrical magnet clutch, self-adaptive electromagnetic clutch of the present invention 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.
