Abstract
The utility model relates to an electromagnet for a spragging gear. The electromagnet for the spragging gear comprises a drive shaft, a fixed iron core, a movable iron core, a wheel gear, a C-shaped retaining ring, a spring and solenoids, wherein the drive shaft is sleeved by the fixed iron core, the movable iron core, the wheel gear and the C-shaped retaining ring in sequence from back to front, the spring is sleeved between the movable iron core and the drive shaft, the front end of the spring is connected with the wheel gear, the outsides of the fixed iron core and the movable iron core are covered by hollow solenoid shells, and the solenoids are installed in the solenoid shells. The electromagnet for the spragging gear produces torque force after being charged with electricity so that the wheel gear does not rotate when external torque force does not exceed a specific value. The electromagnet for the spragging gear has the advantages of being convenient to use, simple to manufacture, low in cost, strong in practical applicability, and wide in application prospect.

Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Like Fig. 1, shown in Figure 2; A kind of electromagnet that is used for spragging gear of the utility model; Comprise driving shaft 13, secured core 2, movable core 11, gear 12, C shape clasp 7, spring 10, line bag 3, on the described driving shaft 13 by the back to preceding secured core 2, movable core 11, gear 12, the C shape clasp 7 of being with successively; Be with spring 10 between described movable core 11 and the driving shaft 13, described spring 10 front end connection gear 12; The described secured core 2 and movable core 11 outsides are surrounded by the line incrustation of hollow, are provided with line bag 3 in the described line incrustation.
Described line incrustation is combined by the protecgulum 4 of its front end and the chase 5 in the rear end and the outside.
Described driving shaft 13 rear ends are provided with rubber sheet gasket 1, and described rubber sheet gasket 1 is positioned at secured core 2 rear ends.
Be provided with plastic casing-pipe 8 between described secured core 2 and driving shaft 13 and the movable core 11.
Be provided with metallic gasket B9 between described secured core 2 and the movable core 11.
Be provided with metallic gasket A6 between described gear 12 and the C shape clasp 7.
After the utility model energising, produce magnetic field and make movable core 11 and secured core 2 adhesives,, thereby gear 12 can not be rotated when its suffered outside torsion is no more than particular value through the effect generation torsion of spring 10.
