Electromagnet；Moving plate and price fixing it is concentric be arranged in parallel in price fixing side, gap is left between Moving plate and price fixing；It is provided with Moving plate
With one-to-one mounting hole on price fixing, Moving plate electromagnet is fixedly installed in mounting hole；Determine on price fixing towards Moving plate side
The pole of disk electromagnet to being arranged alternately, on Moving plate towards price fixing side Moving plate electromagnet pole to being arranged alternately, Moving plate electromagnetism
The untouchable pole to price fixing side ensures the Impact direction and Moving plate relative to price fixing electromagnet of Moving plate electromagnet to that can convert
Rotation direction it is opposite.
Further, price fixing is fixedly installed, and Moving plate is arranged concentrically on slewing.
Further, when price fixing electromagnet and Moving plate electromagnet overlap, pole on Moving plate electromagnet is to change.
Further, price fixing, Moving plate outside are fixedly installed one layer of housing.
Further, four mounting holes are provided with price fixing, the distance at mounting hole to price fixing center is equal.
Further, the price fixing electromagnet on price fixing be respectively the first price fixing electromagnet, it is the second price fixing electromagnet, the 3rd fixed
Disk electromagnet and the 4th price fixing electromagnet；Moving plate electromagnet on Moving plate is respectively the first Moving plate electromagnet, the second Moving plate electromagnetism
Iron, the 3rd Moving plate electromagnet and the 4th Moving plate electromagnet.
Compared with prior art, the present invention has following technique effect：
For the present invention by setting price fixing and Moving plate, the pole of the electromagnet on price fixing and Moving plate passes through conversion to being arranged alternately
The pole of electromagnet on Moving plate is to so that the rotation of the Impact direction and Moving plate relative to price fixing electromagnet of Moving plate electromagnet
Direction is on the contrary, purpose so as to fulfill braking deceleration；The present invention is efficiently solved caused by transmission brake apparatus friction catch
The problem of noise, dust, while solve the problems, such as that fever causes braking effect poor when friction catch works long hours during contact.

Embodiment
Below in conjunction with attached drawing, the present invention is further described：
Please refer to Fig.1-Fig. 4, a kind of contactless electromagnetic brake, including price fixing 1, Moving plate 11, price fixing electromagnet and dynamic
Disk electromagnet；Price fixing 1 is vertically arranged, and the first-class radian of circular arc line on price fixing 1 around 1 center of price fixing is provided with some mounting holes, peace
Dress is fixedly installed price fixing electromagnet in hole；Moving plate 11 and price fixing 1 it is concentric be arranged in parallel in 1 side of price fixing, Moving plate 11 and fixed
Gap is left between disk 1；Be provided with Moving plate 11 with one-to-one mounting hole on price fixing 1, be fixedly installed in mounting hole dynamic
Disk electromagnet；On price fixing 1 towards 11 side of Moving plate price fixing electromagnet pole to being arranged alternately, towards price fixing 1 one on Moving plate 11
The pole of the Moving plate electromagnet of side to being arranged alternately, Moving plate electromagnet towards 1 side of price fixing pole to that can convert, ensure Moving plate electricity
The Impact direction relative to price fixing electromagnet of magnet is opposite with the rotation direction of Moving plate 11.
Price fixing 1 is fixedly installed, and Moving plate 11 is arranged concentrically on slewing.
When price fixing electromagnet and Moving plate electromagnet overlap, pole on Moving plate electromagnet is to change.
Price fixing 1, the outside of Moving plate 11 are fixedly installed one layer of housing 6.
Four mounting holes are provided with price fixing 1, the distance at mounting hole to 1 center of price fixing is equal.
Price fixing electromagnet on price fixing 1 is respectively the first price fixing electromagnet 2, the second price fixing electromagnet 3, the 3rd price fixing electromagnetism
4 and the 4th price fixing electromagnet 5 of iron；Moving plate electromagnet on Moving plate 11 is respectively the first Moving plate electromagnet 7, the second Moving plate electromagnet
8th, the 3rd Moving plate electromagnet 9 and the 4th Moving plate electromagnet 10.
The operation principle of the present invention：
When Moving plate is rotated clockwise to Fig. 4 positions A with respect to price fixing, control electromagnet current direction make price fixing electromagnet and
The pole of Moving plate electromagnet to alternately branch；First price fixing electromagnet is S poles, the first Moving plate electromagnet 7 is N poles, the second price fixing electricity
Magnet 3 is N poles, the second Moving plate electromagnet 8 is S poles, the 3rd price fixing electromagnet 4 is S poles, the 3rd Moving plate electromagnet 9 is N poles,
Four price fixing electromagnet 5 are N poles, the 4th Moving plate electromagnet 10 is S poles so that Moving plate is subject to rotate the opposite moment of torsion in direction.
When Moving plate is rotated clockwise to position B with respect to price fixing, changing electromagnet current direction makes Moving plate turn over B location
During into location of C, price fixing electromagnet poles on price fixing are to constant；First Moving plate electromagnet 7 is S poles, the second Moving plate electromagnet 8 is
N poles, the 3rd Moving plate electromagnet 9 are S poles, the 4th Moving plate electromagnet 10 is N poles.Back and forth change by this rule so that Moving plate is lasting
It is subject to moment of torsion opposite to the direction of rotation, produces braking effect.The size of electric current is controlled, the big of required brake force can be controlled
It is small.
