This utility model one permanent-magnet electromagnetic clutch, employing spring leaf is chip type spring, and volume is little, the effect of transmission revolving force of simultaneously having held concurrently, and simple in construction is easy to maintenance；Magnetic force produced by coil is produced with the elastic force of spring leaf simultaneously is used for offsetting the magnetic force of permanent magnet with joint efforts so that the volume of coil reduces, and raw materials consumption reduces, beneficially cost savings.
Accompanying drawing explanation
Fig. 1 is the internal structure schematic diagram of a kind of permanent-magnet electromagnetic clutch described in the utility model.
Detailed description of the invention
Being described in detail this utility model below in conjunction with the accompanying drawings, the description of this part is only exemplary and explanatory, should not have any restriction effect to protection domain of the present utility model.
A kind of permanent-magnet electromagnetic clutch as shown in Figure 1, including cylinder shell 4, permanent magnet 8, solenoid housing 6, coil 7, frictional disk 16 axle 13, armature 5 and second connecting shaft 2 of closed at both ends,
It is internal that frictional disk 16 axle 13 is arranged on cylinder shell 4, including frictional disk 16 and the first connecting shaft 17, first connecting shaft 17 and the second connecting shaft 2 and cylinder shell 4 axis coinciding, first connecting shaft 17 one end and the first end face 19 centre bore bearing fit of cylinder shell 4, the other end are fixed on frictional disk 16 center
Solenoid housing 6, coil 7 and permanent magnet 8 are between frictional disk 16 and the first end face 19, solenoid housing 6 is enclosed within outside the fixing with cylinder shell 4 of the first connecting shaft 17 and is connected, coil 7 is arranged in solenoid housing 6, and permanent magnet 8 is arranged between solenoid housing 6 and the first end face 19
Second connecting shaft 2 one end and cylinder shell 4 second end face 20 bearing fit, armature 5 centre bore is enclosed within second connecting shaft 2 other end and is slidably matched with this end, and armature 5 is connected by spring leaf 3 with the second connecting shaft 2,
The card that armature 5 is provided with rubbing surface is relative with the card that frictional disk 16 is provided with rubbing surface, and leaves therebetween gap.
Permanent magnet 8 has several, is uniformly distributed around cylinder shell 4 axle center, and each permanent magnet 8 is identical towards the side magnetic pole of solenoid housing 6.
Also including bearing block 14, bearing block 14 is tubular, is enclosed within that the first connecting shaft 17 is outside, one end is fixed on the first end face 19, is provided with bearing 15 between the first connecting shaft 17 and bearing block 14.
If spring leaf 3 has dry tablet, each spring leaf 3 to be uniformly distributed around the second connecting shaft 2, spring leaf 3 one end is fixed on armature 5 outer by screw 12, the other end is fixed on the connection dish of the second connecting shaft 2 by screw 11.
In one end that the first connecting shaft 17 coordinates with the first end face 19, and one end of coordinating with the second end face 20 of the second connecting shaft 2 is mounted on the through hole for shaft coupling, and be separately installed with for fix bearing 15 and bearing 11 the first nut 9 and the second nut 1.
