It is an object of the invention to provide a kind of reasonable in design, small volume, braking ability is good, the strong electric lost system of heat-sinking capability
Dynamic device.
The technical scheme is that：Electric lost brake, includes setting in the yoke of internal coil groove, the coil groove and encourages
Magnetic coil, is placed in the armature of yoke inner face, and described yoke one end is connected with cover plate, provided with connection between the cover plate and armature
The intermediate of drive block, the two ends of the intermediate are provided with friction piece, and the yoke inner face is provided with multiple spring bases and bullet pin
Installing bullet pin in installing spring, the bullet key seat in seat, the spring base, bullet key seat is fixed in one end of the bullet pin.
The armature is provided with bullet pin-and-hole, screw hole.
The periphery of the yoke is provided with outer ring, is connected between yoke and outer ring with epoxy resin layer.
The cover plate is with yoke with screw through installation.
The cover plate, armature, one-to-one radiating positioning hole is circumferentially uniformly distributed in yoke.
The present invention sets multiple springs in yoke, ensure that balance and effective brake of the armature under power failure state.
With finger setting is played between armature and yoke, that is, ensure the accuracy of adhesive between armature and yoke, can guarantee that armature in axle again
Upward flexible motion.Circumferential uniform radiating positioning hole is set on yoke, armature, cover plate, that is, ensures standard when mounted
True property, the temperature that can be kept relative stability again during brake.Connected between yoke and outer ring with epoxy resin layer
Fixation is connect, the periphery of yoke can be protected, the influence of electromagnetism and environment temperature is less subject to, it is ensured that stopping power.It is of the invention special
Digit Control Machine Tool AC adjustable speed motor system and very strict occasion Shi Yongyu not be controlled to position, can be in defense technology field
Task is completed in harsh working environment.

Embodiment
Below by embodiment, and with reference to accompanying drawing, technical scheme is described in further detail.
As shown in Fig. 1~Fig. 5, electric lost brake includes setting in the yoke 1 of internal coil groove 14, the coil groove 14
Magnet exciting coil 3, is placed in the armature 4 of the inner face of yoke 1, and described one end of yoke 1 is connected with cover plate 6, the cover plate 6 and armature 4 it
Between the intermediate 10 provided with connection drive block 7, the intermediate 10 uses irony, inwall and the close-fitting of drive block 7 of intermediate 10
Close, the two ends of the intermediate 10 are provided with friction piece 5, and the external diameter of friction piece 5 is identical with the external diameter of intermediate 10, the yoke 1
Inner face is provided with multiple spring bases 13 and plays installing spring 9 in key seat 15, the spring base 13, and the other end of spring 9 is connected to rank
Installing bullet pin 8 in iron 4, the bullet key seat 15, bullet key seat 15 is fixed in one end of the bullet pin 8.
The armature 4 is provided with bullet pin-and-hole 18, screw hole 17.
The periphery of the yoke 1 is provided with outer ring 2, is connected between yoke 1 and outer ring 2 with epoxy resin layer 11, to magnetic
The periphery of yoke 1 has protective effect.
The cover plate 6 is with yoke 1 with screw 12 through installation.
The cover plate 6, armature 4, one-to-one radiating positioning hole 16 is circumferentially uniformly distributed in yoke 1.
In use, when magnet exciting coil 3 it is electric when, armature 4 attracts to the direction of magnet exciting coil 3, and spring 9 compresses, friction piece 5 with
Space is produced between intermediate 10, the frictional force for acting on intermediate 10 is diminished, the drive block 7 being connected with intermediate 10 can be with
Rotate.When 3 dead electricity of magnet exciting coil, armature 4 is drawn close under the elastic force effect of spring 9 to friction piece 5, and intermediate 10 rubs at two pieces
Under the frictional force collective effect of rub body 5, drive block 7 is set to slow down until stopping operating.
The present invention preferably embodiment is the foregoing is only, but protection scope of the present invention is not limited thereto,
Any one skilled in the art the invention discloses technical scope in, the change or replacement that can be readily occurred in,
It should all be included within the scope of the present invention.
