Abstract
The utility model relates to a rapid adjustment type power-off brake. A base plate is connected with an installing plate through a bolt and an adjusting spring and accordingly a working gap between a friction piece and an armature can be adjusted conveniently and accordingly the power-off brake can be easy to install; the parallel degree of the joint surface of the friction piece and the armature can be ensured and accordingly the braking capability of the power-off brake can be achieved maximally, the eccentric abrasion of the friction piece can be avoided, and the service life can be extended; the rapid adjustment type power-off brake can be easy to adjust particularly when the rapid adjustment type power-off brake is applied to a device which is large in part density and narrow in installation space.
Description
Technical field
The utility model relates to electromagnetic brake field, especially a kind of quick adjustment power-off brake.
Background technique
Power-off brake is to utilize spring and the power supply mechanical device that brake disc is braked and discharged as power source, its working principle is: the interior utmost point, the outer utmost point and base plate have been combined to form a magnet that is respectively the two poles of the earth, magnetic field with the interior utmost point, the outer utmost point, in the time of coil access failure power supply, described spring is pressed in armature on friction plate, on friction plate, form surface friction drag, thereby friction disk is braked, and the equipment that makes to be connected on friction disk is braked; In the time of coil electricity, the pressure in contrast that the magnetic force producing and spring produce, the electromagnetic force that is greater than spring pressure attracts the interior utmost point and the outer utmost point on one side by armature, between armature and friction plate, separate, the surface friction drag that has just produced gap like this between armature and friction plate and make to act on friction plate disappears, and braking is disengaged.In real world applications, the parallelism of adjustable brake gap and guarantee armature working surface and friction disk working surface is the key of performance brake efficiency; The parallelism of armature working surface and friction disk working surface is poor, and braking torque diminishes; Brake clearance is little, in the time that break discharges, produces the fault of trailer and half brake, does not reach release function and increases energy consumption, and heating in a large number, reduces equipment and break life-span; Brake clearance is large, the little or braking failure of braking torque; In when braking, armature thrust easily makes friction disk and the axle that is braked that is connected on friction disk produces axial float.On the equipment large at parts density, installing space is narrow and small, use power-off brake, in quick mounting, easily regulate and ensure on Braking efficiency still more unfeasible; Particularly use power-off brake at mini-plants such as office equipment, tube shaped electric machine, microrobots, above-mentioned technical bottleneck is especially aobvious outstanding.
Summary of the invention
The purpose of this utility model is to change existing power-off brake to be difficult for the problem of installing and regulating, and designs a kind of power-off brake that is easy to installation and adjusting, simple in structure, long service life, and the technical solution of the utility model is so to realize:
Quick adjustment power-off brake, comprises mounting plate, is located at the outer utmost point between base plate and friction disk, the interior utmost point, coil, armature, spring and friction plate, and mounting plate and base plate are bolted, and on the bolt between mounting plate and base plate, are provided with Regulation spring.
As preferably, between mounting plate and base plate, be at least provided with a Regulation spring.
As preferably, be to be at least provided with between mounting plate and friction disk a bearing.
The quick adjustment power-off brake of the utility model design, base plate is connected with adjustment spring with bolt with mounting plate, can regulate easily the working clearance between friction plate and armature, make the installation of power-off brake become easy, and can ensure the parallelism of friction plate and armature junction plane, the stopping power of power-off brake is brought into play to greatest extent, avoid friction plate eccentric wear, increase the service life, particularly large at parts density, on the narrow and small equipment of installing space, use the superiority that regulates of being easy to that more can embody described quick adjustment power-off brake, between mounting plate and friction disk, be at least provided with a bearing, make friction disk be difficult for play, ensure the stable of brake clearance, improve the operational safety of break.
Brief description of the drawings
Accompanying drawing is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
Embodiment: with reference to accompanying drawing, quick adjustment power-off brake, comprise mounting plate 13, be located at the outer utmost point 1, the interior utmost point 2, coil 4, armature 7, spring 11 and friction plate 9 between base plate 3 and friction disk 10, mounting plate 13 is connected by bolt 8 with base plate 3, on the bolt 8 between mounting plate 13 and base plate 3, is provided with Regulation spring 6.
In the interior utmost point 2, the outer utmost point 1 and base plate 3 utilize, the protrusion end riveted joint of the utmost point 2 is integrated, and in the groove that the utmost point 1 and the interior utmost point 2 form outside, coil 4 is set, and by epoxy encapsulation, has just formed electromagnet like this by the outer utmost point 1, the interior utmost point 2, base plate 3 and coil 4; Spring 11 pines are joined and are installed on the interior utmost point 2, spring pin 5 close-fittings are installed on the interior utmost point 2, armature 7 is in axial sliding connection in the other end of the interior utmost point 2 by spring pin 5, the other end of armature 7 is provided with the friction plate 9 being adhered on friction disk 10, friction disk is loaded on mounting plate 13 by bearing 14, on friction disk 10, be provided with Cock screw 12, Cock screw 12 can be connected to friction disk 10 tightenings to be braked on axle, makes friction disk 10 not produce axial float; Mounting plate 13 is bolted on base plate 3 by bolt 8 and Regulation spring 6, base plate 3 can slide axially on bolt, mounting plate 13 for be braked being connected of equipment matrix, spring 6 presses to base plate 3 head one end of bolt 8 all the time, turn bolt 8 just can make armature 7 and the gap of the outer utmost point 1, the interior utmost point 2 change like this, has played the effect of regulating brake working clearance; The turn break radially bolt 8 of diverse location just can make the parallelism of the end face of the outer utmost point 1, the interior utmost point 2 and the end face of armature 7 change, and has played the effect that regulates the outer utmost point 1, the end face of the interior utmost point 2 and the parallelism of armature 7 end faces; When practical application, armature 7 is pressed on friction plate 9 under the thrust of spring 11, and the frictional force therefore producing is braked friction disk 10; In the time that coil 4 obtains electric generation high magnetic fields, armature 7 is drawn onto on the end face of the outer utmost point 1, the interior utmost point 2, between armature 7 and friction plate 9, has produced gap, and frictional force disappears, and the braking of friction disk 10 is disengaged.
