The electromagnetic clutch provided by the utility model has the beneficial effects that by adopting the structure, the coil is electrified to generate magnetic flux so that the armature is actuated, thus friction torque is generated, the combination or separation between the rotary shaft of the motor and the transmission shaft is realized, the high-frequency operation can be met, also the structure is very simple, the volume is smaller, greater torque transmission based on small dimension is realized, performances are better, and the cost is lower.
Description
Technical field
The utility model relates to a kind of engaging and disengaging gear, relates in particular to a kind of magnetic clutch.
Background technique
Clutch is to be used to that two driving parts are separated and the device of combination; Machinery has positive clutch, friction clutch, magnetic clutch, hydraulic coupling and pneumatic clutch at widely used clutch at present; Have only magnetic clutch can satisfy higher operating frequency in these clutches, so magnetic clutch has obtained using widely.But the shortcoming that existing magnetic clutch also exists is the structure more complicated, causes volume bigger, can't realize the function of the big moment of reduced size transmission.
Summary of the invention
Have above-mentioned deficiency in the existing technology in order to overcome, the utility model provides a kind of simple in structure, volume is less, operating frequency is high, carry-over moment is big, cost is low magnetic clutch.
The technological scheme that the utility model solves its technical problem is: a kind of magnetic clutch comprises housing and is arranged on the clutch body in this housing, the Moving plate that said clutch body comprises in the rotating shaft that can be sleeved on motor and rotates with this rotating shaft; End near said housing on this Moving plate has axial region, and this axial region is set with bearing outward, and the end away from said housing on the said Moving plate has shoulder; This shoulder is provided with the circular groove of opening towards said housing; Said bearing outside is equipped with yoke, in this yoke coil is installed, and an end of this yoke is fixed on the said housing; The other end of this yoke stretches in the said circular groove; Also be equipped with the transmission shaft that can move horizontally in the said housing, be set with drive plate on this transmission shaft, be fixed with on this drive plate can with the contacted armature of said Moving plate.
Further, be provided with wearing layer near said armature one side on the said Moving plate.
Further, be provided with spring sheet between said armature and the said drive plate.
Further, said housing comprises casing and case lid, and said yoke is provided with flange near a side of said case lid, and this flange passes through screw on said case lid.
Further, said casing is provided with observation panel, and this observation panel is provided with sealing cover.
The utility model in use; Moving plate is fixed in the rotating shaft of motor; Thereby machine operation drives Moving plate and rotates, and transmission shaft does not rotate, thereby when coil electricity, produces the armature on the magnetic flux adhesive drive plate; Make drive plate and armature on transmission shaft and the transmission shaft move and the armature on the drive plate is close on the Moving plate to the Moving plate direction; Drive drive plate and rotate thereby produce friction torque between armature and the Moving plate, drive plate rotates and drives transmission shaft output, promptly realizes combining between machine shaft and the transmission shaft; When coil blackout, do not produce magnetic flux, armature and Moving plate are separated, thereby realize separating between machine shaft and the transmission shaft.When needs detect the internal structure of housing, can open sealing cover, detect from the internal structure of observation panel housing, after having detected, cover sealing cover and get final product, sealing cover can also prevent that dust from getting into housing.
The beneficial effect of the utility model is: 1. adopt said structure, produce friction torque thereby produce the magnetic flux adhesive armature during through coil electricity, realize the combination between machine shaft and the transmission shaft or separate; Can satisfy high-frequency operation; And structure is very simple, and volume is less, realizes the transmission of big moment with small size; Performance is better, and cost is lower.2. owing to be provided with wearing layer near armature one side on the Moving plate, increase the wear resistance of Moving plate, longer service life.3. owing to be provided with spring sheet between armature and the drive plate, in use,, guarantee the reliability of transmitting even there have strong vibrations also can not produce to be loosening.4. because housing is made up of casing and case lid, installation and removal are convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
With reference to Fig. 1, a kind of magnetic clutch comprises housing and is arranged on the clutch body in this housing; The Moving plate 2 that said clutch body comprises in the rotating shaft 1 that can be sleeved on motor and rotates with this rotating shaft 1, the end near said housing on this Moving plate 2 has axial region, and this axial region is set with bearing 3 outward; End away from said housing on the said Moving plate 2 has shoulder, and this shoulder is provided with the circular groove 4 of opening towards said housing, the said bearing 3 outer yokes 5 that are set with; In this yoke 5 coil 6 is installed; One end of this yoke 5 is fixed on the said housing, and the other end of this yoke 5 stretches in the said circular groove 4, also is equipped with the transmission shaft 7 that can move horizontally in the said housing; Be set with drive plate 8 on this transmission shaft 7, be fixed with on this drive plate 8 can with said Moving plate 2 contacted armature 9.
Be provided with wearing layer 10 near said armature 9 one sides on the said Moving plate 2, increase the wear resistance of Moving plate 2, longer service life.Be provided with spring sheet 11 between said armature 9 and the said drive plate 8, in use,, guarantee the reliability of transmitting even there have strong vibrations also can not produce to be loosening.Said housing comprises casing 12 and case lid 13, and said yoke 5 is provided with flange near a side of said case lid 13, and this flange passes through screw on said case lid 13, and is easy for removal and installation, repairs also very convenient.Said casing 12 is provided with observation panel, and this observation panel is provided with sealing cover 14.
