Abstract
The utility model provides a miniature mistake electric brake, including yoke, coil, spring, armature, friction disc, copper sheathing and connection board, the coil setting is in the yoke, and the connection board passes through the copper sheathing to be connected on the left end face of yoke, and through the fix with screw between connection board and the copper sheathing, the free sliding connection of armature is in the copper sheathing, and the friction disc setting is between armature and connection board. The beneficial effects are that can effectively increase the area of armature, have stronger braking control force, overall structure is compact, adopts the torque transmission mode of friction disc, more resistant high temperature resistant, and the transmission is more energy -conserving.
Description
Technical field
The utility model belongs to electromagnetic braking apparatus field, especially relates to a kind of miniature electricity loss brake.
Background technology
Electromagnetic brake carrys out the Engage and disengage of solenoidoperated cluthes by the power on/off of coil. Existing electromagnetic brake in use, exists outside magnet area too small, the problem that overall structure is not compact, and normally bear driving torque by the Split type structure of rotor gear, in transmission process, consume energy excessive.
Utility model content
In view of this, the utility model is intended to propose a kind of miniature electricity loss brake, can effectively increase the area of armature, has stronger braking control, compact overall structure, and the torque drive mode of employing friction plate, more heat resistant and wear resistant, transmission is more energy-conservation.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of miniature electricity loss brake, comprise yoke, coil, spring, armature, friction plate, copper sheathing and joint cover, described coil is arranged in described yoke, described joint cover is connected to by described copper sheathing on the left side of described yoke, between described joint cover and described copper sheathing, fix by screw, described armature is free to slide and is connected in described copper sheathing, and described friction plate is arranged between described armature and described joint cover.
Further, described spring is positioned at the middle shaft part of described yoke.
Further, described screw is soket head cap screw.
With respect to prior art, miniature electricity loss brake described in the utility model has following advantage:
Under the free state of not energising, armature is covered by the elastic force of spring, and by friction plate, to joint cover side compression, friction plate can not freely-movable, plays braking action; Under the state of energising, the electromagnetic wire that coil produces is through the closed-loop path being made up of yoke and armature, and armature is subject to the electromagnetic force of yoke direction, can overcome the elastic force of spring, to yoke one side compression, now friction plate loses pressing of armature, can freely-movable, conduction torsional interaction. Spring of the present utility model is arranged on the middle shaft part of yoke, can effectively increase the area of armature, contribute to yoke to there is stronger control to armature, compact overall structure, and the torque drive mode of employing friction plate, friction plate is selected PEEK macromolecular material, has high abrasion heat resistance, and transmission is more energy-conservation.
Brief description of the drawings
The accompanying drawing that forms a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.

Detailed description of the invention
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the utility model can combine mutually.
In description of the present utility model, it will be appreciated that, term " " center ", " longitudinally ", " laterally ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of instructions such as " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of device or the element of instruction or hint indication must have specific orientation, with specific orientation structure and operation, therefore can not be interpreted as restriction of the present utility model.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and for example, can be to be fixedly connected with, and can be also to removably connect, or connect integratedly; Can be mechanical connection, can be also electrical connection; Can be to be directly connected, also can indirectly be connected by intermediary, can be the connection of two element internals. For the ordinary skill in the art, can understand the concrete meaning of above-mentioned term in the utility model by concrete condition.
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Figure 1, the utility model provides a kind of miniature electricity loss brake, comprise yoke 1, coil 2, spring 3, armature 4, friction plate 5, copper sheathing 6 and joint cover 7, described coil 2 is arranged in described yoke 1, described joint cover 7 is connected on the left side of described yoke 1 by described copper sheathing 6, fixing by screw 8 between described joint cover 7 and described copper sheathing 6, described armature 4 is free to slide and is connected in described copper sheathing 6, and described friction plate 5 is arranged between described armature 4 and described joint cover 7.
Described spring 3 is positioned at the middle shaft part of described yoke 1.
Described screw 8 is soket head cap screw.
The course of work of this example: under the free state of not energising, armature 4 is covered by the elastic force of spring 3, by friction plate 5, to joint cover 7 side compressions, friction plate 5 can not freely-movable, plays braking action; Under the state of energising, the electromagnetic wire that coil 2 produces is through the closed-loop path being made up of yoke 1 and armature 4, armature 4 is subject to the electromagnetic force of yoke 1 direction, can overcome the elastic force of spring 3, to yoke 1 one side compressions, now friction plate 5 loses pressing of armature 4, can freely-movable, and conduction torsional interaction.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
