Description
Technical field
The utility model relates to electromagnetic brake field, the quiet closed power-off brake of especially a kind of quick adjustment.
Background technique
Power-off brake utilizes spring and power supply as the mechanical device braked brake disc and discharge of power source, and it performs braking under powering-off state, therefore claims power-off brake.Its structure comprises the compositions such as yoke, armature, spring, coil, friction disk, friction plate, release lever, sensitive switch.The working principle of power-off brake is: yoke and the coil be loaded in yoke form electromagnet, when coil access failure power supply, armature is pressed on friction plate by spring, and friction plate forms surface friction drag, thus friction disk is braked, the equipment be connected on friction disk is braked; When the coil is energized, the magnetic force that yoke produces is contrary with the thrust that spring produces, armature is attracted to yoke on one side by the electromagnetic force being greater than spring thrust, make to be separated between armature with friction plate, between armature and friction plate, just create gap like this and the surface friction drag acted on friction plate is disappeared, braking and removed.In use, at work, noise is large, although be provided with adjustable nut and buffering spacer, is all arranged on magnetic pole strength side, because space is unopen, not easily regulates for break, and the effort that abates the noise is time-consuming for power-off brake in the past; The many groups coil used is parallel connection method, when there being one group of coil to damage, break also can be made to perform release work, but release work is halfway, is in strap brake and sensitive switch deceptive movement state when other coil groups obtains electric; The nut that release spanner is in use positioned on pull bar easily loosens, and can cause the fault that manual release lost efficacy or break cannot be braked.
Summary of the invention
The purpose of this utility model changes the quiet adjustment of existing power-off brake to waste time and energy, organize the false work of break semi-brake half release that coils from parallel connection of coils causes and the problem such as manual release work is unreliable more, design a kind ofly be easy to install, quiet easy to adjust fast, the quiet closed power-off brake of quick adjustment of reliable operation, the technical solution of the utility model so realizes:
The quiet closed power-off brake of quick adjustment, comprise yoke, armature, friction disk, friction plate, be located at the coil in yoke and spring, guiding guide pillar, fixing guide pillar, dirt-proof boot, construction bolt, release lever, pull bar, guiding guide pillar is fixed in yoke by hexagon socket head cap screw, interior hexagonal Cock screw is provided with in the screw of described yoke, interior hexagonal Cock screw end is provided with push rod successively, plug and large O type circle, described construction bolt is successively through yoke, fixing guide pillar is connected with braked body with the via hole of armature, described pull bar is successively through armature, yoke, the via hole of release lever, and with thin nut, dish pad is connected with pull bar tailing screw flight, thrust-bearing is provided with between described release lever and thin nut, described yoke is offered multiple coil groove, multiple coil groove divides two groups to be arranged symmetrically with, coil is positioned in the coil groove of yoke, and be divided into two groups to be arranged symmetrically with by coil groove, often the multiple coils organized in coil are tandem-type connection.Large O type circle contacts with armature, in such adjustment, hexagonal Cock screw just can make the crush of large O type circle be in appropriate location, just can effectively cushion or eliminate the collision between yoke and armature, reduce or abate the noise, because hexagonal Cock screw is arranged at the more spacious back side of yoke, therefore regulate the time abated the noise greatly to shorten, reach the object of quick adjustment.Thrust-bearing, makes not easily to loosen between pull bar and thin nut, effectively avoids manual release to lose efficacy and the idle fault of break.
As preferably, between described guiding guide pillar and armature, be provided with composite bearing, between guiding guide pillar end and armature, be provided with little O type circle.Yoke and the armature guide pillar that leads is formed by composite bearing and is slidably connected, and guiding guide pillar is fixed in yoke by hexagon socket head cap screw.Adopt and form by composite bearing 7 structure be slidably connected, and be provided with little O type circle in guiding guide pillar end, make break in adhesive or releasing course, the fast moving of armature becomes slow and steady, not easily tilt, make the dotted line Fast Collision of armature and yoke or friction plate become plane to collide at a slow speed, reduce noise; Be soft-touch between composite bearing and guiding guide pillar, both wear-resisting generations that turn avoid noise.
The beneficial effects of the utility model are:
1, be arranged symmetrically with two groups of coil groups, often organized between the coil in coil groups and adopt tandem-type connection, avoid the fault of the vacation work of break semi-brake half release that former parallel connection method produces.
2, conveniently can regulate the crush of large O type circle at the back side that yoke is more spacious rapidly, make it to play optimized buffer effect, make break can work in mute state rapidly.
3, release lever is provided with thrust-bearing, makes not easily to loosen between pull bar and thin nut, effectively avoids manual release to lose efficacy and the idle fault of break, improves the reliability of break.

Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
Embodiment: with reference to accompanying drawing, the quiet closed power-off brake of quick adjustment, comprises yoke 1, armature 2, friction disk 3, friction plate 4, be located at the coil 5 in yoke 1 and spring 6, guiding guide pillar 8, fixing guide pillar 11, dirt-proof boot 12, construction bolt 17, release lever 18, pull bar 19, guiding guide pillar 8 is fixed in yoke 1 by hexagon socket head cap screw 9, is provided with interior hexagonal Cock screw 16 in the screw of described yoke 1, and interior hexagonal Cock screw 16 end is provided with push rod 15 successively, plug 14 and large O type circle 13, described construction bolt 17 is successively through yoke 1, fixing guide pillar 11 is connected with braked body with the via hole of armature 2, and described pull bar 19 is successively through armature 2, yoke 1, the via hole of release lever 18, and with thin nut 21, dish pad 22 is connected with pull bar 19 tailing screw flight, thrust-bearing 20 is provided with between described release lever 18 and thin nut 21, described yoke 1 offers multiple coil groove, multiple coil groove divides two groups to be arranged symmetrically with, coil 5 is positioned in the coil groove of yoke 1, and be divided into two groups to be arranged symmetrically with by coil groove, often the multiple coils organized in coil 5 are tandem-type connection.During coil 5 power-off, spring 6 promotes armature 2 and friction disk 3 to braked body electric motor end cap 25 while contact and compress, if motor shaft 27 has rotation trend, now friction disk 3 and can surface friction drag be produced between electric motor end cap 25 and armature 2, motor shaft 27 is braked, then contrary when opposite coil 5 is energized, motor shaft 27 is released, and can freely rotate.Large O type circle 13 contacts with armature 2, in such adjustment, hexagonal Cock screw 16 just can make the crush of large O type circle 13 be in appropriate location, just can effectively cushion or eliminate the collision between yoke 1 and armature 2, reduce or abate the noise, because hexagonal Cock screw 16 is arranged at the more spacious back side of yoke 1, therefore regulate the time abated the noise greatly to shorten, reach the object of quick adjustment.Thrust-bearing 20, makes not easily to loosen between pull bar and thin nut 21, effectively avoids manual release to lose efficacy and the idle fault of break.
