Description
Technical field
The present invention relates to a kind of electromagnetic brake, the electromagnetic braking of friction plate loss when more particularly to a kind of reduction separating brake
Device.
Background technique
Electromagnetic brake have compact-sized, easy for installation, wide adaptability, noise is low, working frequency is high, it is sensitive,
The advantages that reliable is braked, is a kind of very widely used, ideal automated execution element.It is mainly used in packaging and packing
Machinery, metalworking machinery, machine work, handling machinery, paper is mechanical, woodworking machinery, and measurement is mechanical, food processing machinery
Deng.
The brake that braking is realized using galvanomagnetic-effect, is divided into electromagnetic power brake, electromagnetic whirlpool brake and electromagnetism
The diversified forms such as friction brakes.Wherein the principle of electromagnetic friction brake is that magnetizing coil energization generates magnetic field, is passed through
Magnetic yoke adhesive armature, armature are realized by coupling flange and are braked to axis, can be divided into energization braking according to mode of braking and power-off is made
It is dynamic.
The working environment of electromagnetic brake is complicated, and brake component is easily damaged, and it is slow, dynamic often to will appear brake action
Make some failures such as entanglement, usually mechanical breakdown and electric fault institute extremely.Common mechanical breakdown phenomenon have brake force it is insufficient,
Though brake arm cannot open, brake declutches slow motion, tripping spring tightens, braking moment also tunes up, but still cannot make in time
Phenomena such as dynamic, the unexpected failure of brake, braked wheel temperature are excessively high, and brake block smolders, misfunctioning of brake.
Electromagnetic brake is a very important component in the machines such as elevator, stage, steamer, metallurgy, hoisting machinery.But
Few pairs of brake force and braking process are measured in real time in existing mechanical equipment, only manually periodically repair tune
It is whole, therefore the accidental event such as the abrasion of pair that rubs in use to brake, fatigue, the fluctuation of voltage of tripping spring
Barrier cannot be accomplished to find and prevent in time.
The inventors found that the reason of causing above-mentioned failure is, traditional electromagnetic brake brake is in gate-dividing state
Under, since friction plate is axially unlocked, the axial movement of armature will lead to the friction plate axial float on shaft spline, cause to rub
Pad is repeatedly with armature collision friction, and loss increases and temperature increases.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of electromagnetic brake of friction plate loss when reduction separating brake, energy
Loss when friction plate separating brake is enough reduced, fever is reduced.
The technical solution adopted by the present invention to solve the technical problems is: friction plate is lost when providing a kind of reduction separating brake
Electromagnetic brake, including axle sleeve and magnetic yoke, are successively cased with joint cover, friction plate and armature on the axle sleeve, the joint cover and
Armature is connected by air gap adjusting screw with the magnetic yoke, and spring, the friction plate are additionally provided between the magnetic yoke and armature
The left and right sides be provided with groove, be provided with limiting device in the groove, when brake closes a floodgate, the limiting device not shadow
The contact for ringing friction plate and armature and joint cover, keeps friction plate working properly, and when brake separating brake, the limiting device is institute
It states friction plate and axial limitation is provided, guarantee that there are gaps between friction plate and armature and joint cover.
The groove is located at the position on friction plate close to axle sleeve.
The thickness of the limiting device under normal circumstances is greater than the depth of groove, and the limiting device is by compressed thickness
Degree is less than the depth of groove.
The limiting device is spring shim.
The axle sleeve is equipped on the side of armature and is additionally provided with check ring, and the check ring is in brake separating brake
Guarantee that there are gaps between armature and limiting device.
Beneficial effect
Due to the adoption of the above technical solution, compared with prior art, the present invention having the following advantages that and actively imitating
Fruit: the present invention is by increasing spring shim in friction plate rear and front end and the side of check ring being arranged in spring shim side
Formula, spring shim does not influence the contact of friction plate with armature and joint cover when brake, when separating brake guarantee friction plate with
There is gap between armature and joint cover, thus in the case where not changing the foundation structure of electromagnetic brake, it is effective to reduce
The loss and fever of friction plate when electromagnetic brake separating brake.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
Embodiments of the present invention are related to a kind of electromagnetic brake of friction plate loss when reduction separating brake, as shown in Figure 1, packet
Axle sleeve 8 and magnetic yoke 1 are included, joint cover 5, friction plate 6 and armature 4 are successively cased on the axle sleeve 8, the joint cover 5 and armature 4 are logical
It crosses air gap adjusting screw 2 to be connected with the magnetic yoke 1, spring 3, the friction plate 6 is additionally provided between the magnetic yoke 1 and armature 4
The left and right sides be provided with groove, be provided with limiting device 7 in the groove, when brake closes a floodgate, the limiting device 7 is not
The contact for influencing friction plate 6 and armature 4 and joint cover 5, keeps friction plate 6 working properly, and when brake separating brake, the limit is filled
It sets 7 and provides axial limitation for the friction plate 6, guarantee that there are gaps between friction plate 6 and armature 4 and joint cover 5.
Limiting device 7 uses spring shim in present embodiment, and uses the reeded friction plate 6 in two sides improved,
The inner ring of friction plate 6 is arranged in the position of groove, and the spring shim of correspondingly-sized is respectively studded in groove, and the side of spring shim has
The axial movement of 9 limited spring gasket of check ring, the thickness of spring shim should be able to make surface of its surface higher than friction plate, this
There is spring shim to provide gap when sample just can guarantee axis normal rotation between friction plate and armature and joint cover.In addition, braking
When spring shim by compressed thickness should be able to make its surface be lower than friction plate surface, just can guarantee does not influence when braking in this way
The normal work of friction plate.
It is not difficult to find that the present invention is by increasing spring shim in friction plate rear and front end and being arranged in spring shim side
The mode of check ring, spring shim does not influence the contact of friction plate with armature and joint cover when brake, when separating brake
Guarantee there is gap between friction plate and armature and joint cover, thus the case where not changing the foundation structure of electromagnetic brake
Under, the loss and fever of friction plate when being effectively reduced electromagnetic brake separating brake.
