Abstract
The invention discloses an electromagnetic clutch device. The electromagnetic clutch device comprises a rotary shaft, an electromagnet, an armature and a transmission wheel. The electromagnet is fixed on the rotary shaft, the armature is connected with one side of the transmission wheel, the armature and the transmission wheel are slidably sleeved on the rotary shaft, the armature faces to the electromagnet, and a friction plate is arranged between the electromagnet and the armature; and the friction plate is fixed on the electromagnet and/or the armature, the rotary shaft is as an output shaft of an electromotor, and the transmission wheel is any one of a gear, a worm wheel, a chain wheel and a pulley. The electromagnetic clutch device is mainly used for an energy-storage closed type switch, when the energy storage of the switch is abnormal, the electromagnetic clutch device can automatically separate the electromotor from the switch in transmission so as to solve the problems that the clutch device used by the existing energy-storage closed type switch cannot automatically detect and judge the abnormal conditions of the energy storage of the switch in the process that the electromotor drives the switch to store the energy, and cannot automatically separates the electromotor from the switch in transmission. The electromagnetic clutch device provided by the invention has the advantages of simple structure, small volume and safety and reliability.
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 detect, judge the unusual situation of switch energy storage automatically in the process of motor drives switch energy storage, and automatically motor is separated with the switch transmission, causes switch to damage in this case sometimes.
Summary of the invention
The purpose of this invention is to provide a kind of electromagnetic clutch device; Arrangement of clutch to solve existing stored energy closing switch use can not detect, judge the unusual situation of switch energy storage automatically in the process of motor drives switch energy storage, and the problem of automatically motor being separated with the switch transmission.
The objective of the invention is to realize through following technical scheme:
A kind of electromagnetic clutch device; Comprise rotating shaft, electromagnet, armature and drive, said electromagnet is fixed in the rotating shaft, a side of said armature and drive be linked together; Said armature and drive are sleeved in the said rotating shaft together slidably, and said armature is in the face of electromagnet.
Said electromagnet and armature residual gap are provided with friction plate, and said friction plate is fixed on electromagnet and/or the armature.
Said rotating shaft is the output shaft of motor.
Said drive is any in gear, worm gear, sprocket wheel and the belt pulley.
The present invention is through utilizing the principle of friction slip; Realized in the process of motor drives switch energy storage; To switch energy storage unusual automatic detection, judgement, and in time motor is separated with the switch transmission, have advantage simple in structure, that volume is little, safe and reliable.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is the structural representation of electromagnetic clutch device of the present invention.
Among the 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, said electromagnet 2 is fixed in the rotating shaft 1, a side of said armature 3 and drive 4 be linked together; Said armature 3 is sleeved in the said rotating shaft 1 with drive 4 together slidably, and said armature 3 is in the face of electromagnet 2.
Preferably, 3 in said electromagnet 2 and armature are provided with friction plate 5, and said friction plate 5 is fixed on electromagnet 2 and/or the armature 3.
Said rotating shaft 1 is the output shaft of motor 6.
Said drive 4 is any in gear, worm gear, sprocket wheel and the belt pulley.
On the stored energy closing switch, be applied as example with the present invention; Its operation principle is: after electromagnet 2 energisings; The magnetic force that produces is adsorbed on armature 3 and drive 4 (like illustrated sprocket wheel) on the friction plate 5 on its end face together; When the output shaft of motor 6 rotated, the drive 4 that is positioned on motor 6 output shafts just rotated with output shaft with electromagnet 6 with armature 3, thereby drives the switch energy storage.
When the switch energy storage is unusual; The resistance of switch will increase, and during maximum static friction force that the resistance of treating switch can cause greater than the absorption affinity of 2 pairs of armature 3 of electromagnet and sprocket wheel, 3 in the friction plate 5 of electromagnet 2 end faces and armature just skid; Be that motor 6 drives electromagnet 2 rotations; And armature 3 does not rotate with sprocket wheel, thereby has realized separating of motor 6 and switch, has protected switch.
The present invention is mainly used in the stored energy closing switch, can when the switch energy storage is unusual, automatically motor be separated with the switch transmission, has advantage simple in structure, that volume is little, safe and reliable.
