Description
Technical field
The present invention relates to a kind of arrangement of clutch, particularly a kind of electromagnetic clutch device.
Background technology
The arrangement of clutch of existing stored energy closing switch use can not drive in the process of energy storing of switch the situation automatically detecting, judge energy storing of switch exception at motor, and is automatically separated with switch transmission by motor, causes switching damage sometimes in this case.
Summary of the invention
The object of this invention is to provide a kind of electromagnetic clutch device, the situation automatically detecting, judge energy storing of switch exception can not be driven in the process of energy storing of switch at motor with the arrangement of clutch solving existing stored energy closing switch use, and the problem automatically motor is separated with switch transmission.
The object of the invention is to be achieved through the following technical solutions:
A kind of electromagnetic clutch device, comprise rotating shaft, electromagnet, armature and drive, described electromagnet is fixed in rotating shaft, and the side of described armature and drive is linked together, described armature is sleeved on slidably in described rotating shaft together with drive, and described armature is in the face of electromagnet.
Described electromagnet and armature residual gap are provided with friction plate, and described friction plate is fixed on electromagnet.
Described rotating shaft is the output shaft of motor.
Described drive is any one in gear, worm gear, sprocket wheel and belt pulley.
The present invention is by utilizing the principle of friction slip, achieve and drive in the process of energy storing of switch at motor, to automatic detection, the judgement of energy storing of switch exception, and in time motor is separated with switch transmission, there is the advantage that structure is simple, volume is little, safe and reliable.
Accompanying drawing explanation
According to drawings and embodiments the present invention is described in further detail below.
Fig. 1 is the structural representation of electromagnetic clutch device of the present invention.
In figure: 1, rotating shaft; 2, electromagnet; 3, armature; 4, drive; 5, friction plate; 6, motor.
Embodiment
As shown in Figure 1, electromagnetic clutch device of the present invention, comprise rotating shaft 1, electromagnet 2, armature 3 and drive 4, described electromagnet 2 is fixed in rotating shaft 1, the side of described armature 3 and drive 4 is linked together, described armature 3 is sleeved in described rotating shaft 1 slidably together with drive 4, and described armature 3 is in the face of electromagnet 2.
Preferably, be provided with friction plate 5 between described electromagnet 2 and armature 3, described friction plate 5 is fixed on electromagnet 2.
Described rotating shaft 1 is the output shaft of motor 6.
Described drive 4 is any one in gear, worm gear, sprocket wheel and belt pulley.
On stored energy closing switch, example is applied as with the present invention, its operation principle is: after electromagnet 2 is energized, armature 3 is adsorbed on the friction plate 5 on its end face by the magnetic force produced together with drive 4 (as illustrated sprocket wheel), when the output shaft of motor 6 rotates, the drive 4 be positioned on motor 6 output shaft just rotates with output shaft with armature 3 together with electromagnet 6, thus drives energy storing of switch.
When energy storing of switch is abnormal; the resistance of switch will increase; when the maximum static friction force that the absorption affinity that the resistance of switch is greater than electromagnet 2 pairs of armature 3 and sprocket wheel can cause; just skid between the friction plate 5 of electromagnet 2 end face and armature 3; namely motor 6 is with motor magnet 2 to rotate; and armature 3 and sprocket wheel do not rotate, thus achieve being separated of motor 6 and switch, protect switch.
The present invention is mainly used in stored energy closing switch, when energy storing of switch is abnormal, automatically can be separated with switch transmission by motor, has the advantage that structure is simple, volume is little, safe and reliable.
Claims (4)
