Specific embodiment
The present invention is described in further details below.Referring to Fig. 1, a kind of magnetoelectricity clutch, it includes axis 2, spring leaf
3, shell 4, armature 5, solenoid housing 6, coil 7, permanent magnet 8, deep groove ball bearing 10, screw 11, screw 12, angular contact ball bearing
13, rub dish axle 14, deep groove ball bearing 15 and bearing block 16 etc..Axis 2 is supported in shell 4 with deep groove ball bearing 10, and nut 1 is used
In fixing bearing 10；Axis 2 and shell 4 are concentric, and there is the hole of a shaft coupling at the center of axis 2.
Armature 5 is connected on axis 2 with spring leaf 3, and armature 5 and axis 2 are concentric；Armature 5 can be axially moveable；Armature 5 with
There are air gaps between the left end large end face for the dish axle 13 that rubs；There is friction material on the right end large end face of armature 5.The one of spring leaf 3
End screw 12 is connected on armature 5, and other end screw 11 is connected on axis 2；The quantity of spring leaf 3 is 2~10, with rank
The central axis of iron 5 is axis, is uniformly distributed along the circumference.The material of screw 11,12 is non-magnet material.
Bearing block 16 is installed on the right end of shell 4, and is connected with shell 4, and bearing block 16 and shell 4 are concentric.
Solenoid housing 6 is installed in shell 4, and is connected with shell 4, and solenoid housing 6 and shell 4 are concentric.Coil 7 is installed on
In solenoid housing 6.
Permanent magnet 8 is installed between solenoid housing 6 and bearing block 16, the quantity of permanent magnet 8 is 2~10, with bearing
The central axis of seat 16 is axis, is uniformly distributed along the circumference, all permanent magnets 8 are identical close to one end polarity of solenoid housing 6.
Friction dish axle 14 is supported in bearing block 16 with two deep groove ball bearings 15, and nut 9 is for fixing deep groove ball bearing
15；There is the hole of a shaft coupling at the center of friction dish axle 14, has friction material on the large end face of left end.
Angular contact ball bearing 13 is installed between axis 2 and friction dish axle 14.
There are three uniformly distributed kidney slots in the disk for the dish axle 14 that rubs.
The working principle of the invention is: above-mentioned magnetoelectricity clutch, and when coil 7 is not powered on, permanent magnet 8 is generated as schemed
Magnetic field shown in 1 dotted line, adhesive armature 5 make spring leaf 3 that flexible deformation occur, and armature 5 is axially moveable to be pasted with friction dish axle 14
It closes, extraneous rotary force is transmitted on armature 5 by axis 2 by spring leaf 3, and armature 5 is transmitted rotating force to by frictional force again
In the dish axle 14 that rubs, reach the transmitting of rotary force；Three uniformly distributed kidney slots are played every magnetic in the disk of its middle friction tray axis 14
Effect, make magnetic flux can be for delivery on armature 5；When coil 7 is powered, coil 7 generates magnetic field, the magnetic field and 8 magnetic of permanent magnet
On the contrary, coil magnetic field is offseted with magnetic field of permanent magnet, armature 5 is in free state, in the case where the elastic force of spring leaf 3 is acted on rub
It wipes the separation of dish axle 14 to disconnect, no longer transmitting rotary force.Above-mentioned the used spring leaf 3 of magneto magnetoelectricity clutch is chip type spring,
It is small in size, while and play a part of transmitting rotary force, structure is simple, easy to maintenance；Magnetic force and spring caused by coil 7 simultaneously
Resultant force caused by the elastic force of piece 3 is used to offset the magnetic force of permanent magnet 8, so that the volume of coil 7 reduces, raw materials consumption drop
It is low, be conducive to cost savings.
