Specific embodiment:
Make furtherly below with reference to technical effect of the attached drawing to the design of the utility model, specific structure and generation
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
It refering to fig. 1, is the utility model one example structure schematic diagram, the related one kind of the utility model is forever shown in 2,3
Magnetic electricity loss brake has the first brake body 1 and the second brake body 2, is disposed with coil 3 on first brake body 1,
And first brake body 1 have first braking end face 11, coil 3 be powered after generate operating fields.On second brake body 2
Magnetizer 4 and permanent magnet 5 are assembled, and makes the second brake body 2 towards the side of the first braking end face 11 of the first brake body 1
Attractive magnetic force end is formed, which is attracted the first braking end face 11 of the first brake body 1 in 3 power loss of coil.
Coil 3 and permanent magnet 5 are split on the first brake body 1 and the second brake body 2, the brake or clutch that form in this way
Afterwards, whole height is shorter than existing permanent magnet brake, and magnetic circuit is short, and brake force is big, and the part of assembling coil can be allowed to be made very small
It is very thin, there are also be exactly can directly on rack, door simple next coil, so that it may realize it is automatically controlled absorption, brake, shutdown etc.
Function.Structure is simple, small in size, and braking moment is big, and permanent magnet is high-efficient, and performance is stablized, and consistency is good, reduces cost of manufacture,
Energization brake can be allowed to become permanent magnet brake for electricity losing with the brake(-holder) block of the existing energization brake of direct substitution.
Shown in Fig. 1,2,3, in the present embodiment, second brake body 2, magnetizer 4 and permanent magnet 5 are stacked, and are led
Magnet 4 brakes end face 11 close to the first of the first brake body 1, and two magnetic poles of permanent magnet 5 are braked with magnetizer 4 and second respectively
Main body 2 sticks together, and the second brake body 2, which has to pass through from 4 side of magnetizer to the first of the first brake body 1, brakes end face
11 are formed together attractive magnetic force end close to the braking parts 21 extended, the braking parts 21 and magnetizer 4.Outside magnetizer 4
Periphery is equipped with the mutually close place of the second brake body 2 every magnetic patch 6, separates magnetizer 4 and the second brake body 2 every magnetic patch 6,
Prevent the second brake body 2 with magnetizer 4 from directly contacting, the second brake body 2 forms a yoke surface with magnetizer 4, right
The object of magnetic conductivity generates adsorption capacity.Permanent magnet 5 is correspondingly also covered every magnetic patch 6, to avoid the absorption of the objects such as impurity or iron filings
Onto permanent magnet 5, the trend of the magnetic line of force is influenced, there is dust-proof, protection effect.Fig. 1, shown in 2, magnetizer 4 is torus, is passed through
Screw is locked to the second brake body 2, and screw accordingly passes through permanent magnet 5, shown in Fig. 1, the braking parts 21 of the second brake body 2 from
The inner ring side of magnetizer 4 extends, certainly can also as shown in Fig. 2, the braking parts 21 of the second brake body 2 from the outer ring of magnetizer 4
Side extends, and can equally form attractive magnetic force end.In order to facilitate the installation of permanent magnet 5, the second brake body 2 of this implementation
And/or the corresponding site of magnetizer 4 can suitably offer scarfing slot, for 5 location and installation of permanent magnet, which can make permanent magnet
5 magnetic line of force more can sufficiently be used, and structure is also stronger.Permanent magnet 5 is preferably rare earth strong magnets, and shape is entire
Circular or lumpy is distributed in circular ring shape, and the thickness direction saturation of permanent magnet 5 magnetizes, and is had larger adsorption capacity, is met system
Dynamic or clutch requirement.
