Working principle of the present invention is following:
Fastening screw nut 7 links together central shaft 4 and transmission shaft 15, and transmission shaft 15 provides powered rotation by the outside.Under the situation that coil 12 is not switched on like Fig. 1; There is gap Z in armature 9 with rotor 10; Drive central shaft 4 when transmission shaft 15 rotates and rotate together, the rotor 10 that links together with central shaft 4 so also with transmission shaft 15 rotations, be connected through bearing 1 between central shaft 4 and the belt pulley 5; So do not rotate at central shaft 4 rotating process middle belt pulleys 5; Belt pulley 5 links together through sheet spring 18 and armature 9, exists under the situation of gap Z at armature 9 and rotor 10, and armature 9 is held by sheet spring 18 and contacted no relative movement with brake disc cover 8 end faces.Under the situation of coil 12 energising, coil 12 produce electromagnetic attracting force armature 9 to rotor near, armature 9 overcomes sheet spring 18 pulling force; Finally contact with rotor 10 end face that fits together; Gap Z disappears, because rotor 10 is under the drive of transmission shaft 15, to rotate, armature 9 drives belt pulley 5 and rotates after rotor 10 fits together; Thereby belt pulley 5 transferring power are to outside; Disappear in coil 12 outage back electromagnetic forces, sheet spring 18 pulling armature 9 disengaging rotors 10 are fitted with brake disc cover and are realized braking, and belt pulley stops operating.
The action of magnetic clutch is in the whole process: when coil 12 energisings, electromagnetic force overcomes sheet spring 18 and attracts armature 9 to contact with rotor 10 end faces, thereby belt pulley 5 rotates; When coil 12 outages, electromagnetic force disappears, and sheet spring 18 pulling armature 9 reset and contact with brake disc cover 8, thereby realize braking.
The effect of coil 12: coil 12 is installed in the stator case 11, and the power effect that energising generation electromagnetic force overcomes sheet spring 18 attracts armature 9 to combine to realize the rotation of belt pulley 5 with rotor 10.
The effect of sheet spring 18: sheet spring 18 is installed between armature 9 and the belt pulley 5; 5 places are divided equally, and link into an integrated entity with belt pulley 5 through rivet and armature 9, and sheet spring 18 is held the braking of armature 9 and brake disc cover 8 applying realization belt pulleys 5; When coil 12 energisings produce electromagnetic force; Electromagnetic force is overcome sheet spring 18 greater than sheet spring 18, armature 9 power effect contacts with rotor 10, and when electromagnetic force disappeared, sheet spring 18 pulling armature 9 resetted and contact with brake disc cover 8.
The effect of armature 9: when coil 12 energising, is combined to realize the rotation of belt pulley 5 with rotor 10 by electromagnetic attracting force, when the outage electromagnetic force disappears by sheet spring 18 pulling armature 9 and brake disc cover 8 applyings, the braking of realization belt pulley 5.
The effect of brake disc cover 8:, when armature 9 is retracted by sheet spring 18, realize the braking of belt pulley 5 for armature 9 provides rubbing surface.
The effect of central shaft 4: transferring power.
The effect of stator case 11: the main body of whole magnetic clutch, be whole clutch, central shaft 4, brake disc cover 8, coil 12 provide the mounting point.
The effect of belt pulley 5: outputting power.
The effect of rotor 10, armature 9 and strip hole 21: processed the strip hole 21 on 3 circumference on rotor 10 parts, be evenly equipped with 3 grooves on each circumference, and also be processed with 2 strip holes 21 on the circumference on the armature 9, be evenly equipped with 3 grooves on each circumference.When clutch was switched on, coil 12 produced 9 actions of electromagnetic attracting force armature, and the electromagnetic force magnetic line of force passes rotor 10 strip holes 21 and directly acts on armature 9, the route direction of the magnetic line of force such as Fig. 4 arrow curve indication.And just can it is evident that strip hole 21 roles through curve.Energising is that the magnetic line of force passes rotor 10 strip holes 21 and directly acts on armature 9, and electromagnetic force is a loop, goes out to be sent back to the South Pole from the arctic; When the magnetic line of force acts on armature 9, originally can directly pass armature 9, rotor 10 is directly got back to the South Pole, but because rotor 10 all is processed with strip hole 21 with armature 9; When the magnetic line of force passes armature 9, be to have only air, but air reluctance greatly only detours and pass rotor 10, and on rotor 10, occur the phenomenon of strip hole 21 too passing by strip hole 21; The magnetic line of force is just as shown in Figure 4 then, the circuitous South Pole of getting back to, the effect of Here it is between rotor 10 and armature 9 processing strip hole 21; And the dislocation layout between rotor 10 and the armature 9 also is considerable; So improve electromagnetic force to a great extent, under the situation of identical coil 12 power, obtained bigger electromagnetic force; Satisfy the clutch moment of torque requirement, thereby on energy-conservation, promote greatly.
Need to prove that at last the above is merely preferred embodiment of the present invention, rather than to the qualification of technological scheme of the present invention, anyly be equal to replacement or corresponding improvement, still within protection scope of the present invention what technical characteristics of the present invention was done.
