Abstract
The utility model provides a take arrester spring adjusting device of auto -lock, relates to the electromagnetism and loses the electric brake field, and lose electric brake, adjusting nut and regulation round pin by the electromagnetism and constitute, the electromagnetism loses the electric brake and comprises motor shaft, brake disc, armature, yoke, spring and geared sleeve, the installation of the spring hole bottom portion of spring is provided with adjusts the round pin, installs adjusting nut at the tip of adjusting the round pin, adjusting nut binds with yoke hole screw mutually, adjusting nut is last set up fluted. The utility model discloses convenient to use, safety and stability nature be high, can prevent to cause the not hard up potential safety hazard that leads to of spring because of the vibrations of stopper during operation, has guaranteed braking effect.
Description
Technical field:
The utility model relates to electromagnetic power-off brake field, is specifically related to a kind of brake spring with self-lockingAdjusting device.
Background technology:
Electromagnetic power-off brake is energising disengaging, the friction brakes of spring to break braking. Extensive useIn the machineries such as metallurgy, building, chemical industry, food, lathe, printing, packaging, and in the time of power-off (anti-danger)The occasions such as braking. This brake has that compact conformation, easy for installation, wide adaptability, noise are low, workWorking frequency is high, be active in one's movements, brake the advantages such as reliable, is a kind of desirable automated execution element. SystemThe moving external half-wave rectifier of device, is rectified into direct current by single-phase alternating current. Power up rear winding and produce magnetic field, willArmature sucks back, and armature compression is simultaneously fixed on the spring in iron core. When dead electricity, winding electric discharge, spring willArmature ejects, and armature will produce braking moment on frictional disk, and motor is stopped, but because of brake workAs time have seismism, after long-play, spring can produce loosening phenomenon, cause brake torque reduce,Will affect greatly like this braking effect and ability.
Utility model content:
Technical problem to be solved in the utility model be to provide a kind of stability easy to use, safe high,Vibrations can prevent from working because of brake time cause the loosening potential safety hazard causing of spring with self-lockingBrake spring adjusting device.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
With a brake spring adjusting device for self-locking, by electromagnetic power-off brake, adjusting nut and tuneJoint pin composition, described electromagnetic power-off brake is by motor shaft, brake disc, armature, yoke, spring and toothWheel case composition, the spring eye bottom of described spring is installed and is provided with adjustment pin, installs in the end of adjustment pinHave adjusting nut, described adjusting nut connects mutually with yoke inner hole thread, on described adjusting nut, offersGroove, described groove semicircular in shape structure, the quantity of groove is consistent with adjustment pin quantity;
First electromagnetic power-off brake is to apply pressure to armature by spring, the friction plate on brake disc is compressed, fromReach the object of braking and produce moment of friction, but in reality is used, conventionally will carry out braking momentAdjust, to adjust object this patent and set up an adjustment pin in yoke spring eye bottom in order to reach, by with yokeSpring force is adjusted in the rotation of the adjusting nut that inner hole thread connects, and in the time that adjustment pin is screwed into, spring force increases,When braking moment increases, back-outs, spring force reduces, and braking moment reduces, but while work due to brakeHave seismism, after long-play, adjusting nut can produce loosening phenomenon, causes brake torque to reduce,For preventing the generation of this type of phenomenon, the uniform plane contacting with adjustment pin at adjusting nut is provided with and regulatesThe consistent semi-circular recesses of pin quantity, while rotating adjusting nut, makes the semicircle head of adjustment pin just in time fall into tuneIn joint nut plane semi-circular recesses, under the reaction force of spring force, adjusting nut can be because of vibrationsProduce loosening phenomenon.
The beneficial effects of the utility model are: stability easy to use, safe is high, can prevent because of brakingThe vibrations in device when work cause that spring is loosening and the potential safety hazard that causes has ensured braking effect.

Detailed description of the invention:
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to brightWhite understanding, below in conjunction with concrete diagram, further sets forth the utility model.
As shown in Figure 1, Figure 2 and Figure 3, a kind of brake spring adjusting device with self-locking, by electromagnetism dead electricityBrake, adjusting nut 8 and adjustment pin 7 form, and described electromagnetic power-off brake is by motor shaft 1, brake disc2, armature 3, yoke 4, spring 5 and geared sleeve 6 form, and the spring eye bottom of described spring 5 is installed and arrangedThere is adjustment pin 7, in the end of adjustment pin 7, adjusting nut 8 is installed, described adjusting nut 8 and yoke 4 endoporusScrew thread connects mutually, on described adjusting nut 8, offers groove 9, described groove 9 semicircular in shape structures, groove9 quantity is consistent with adjustment pin 7 quantity;
First electromagnetic power-off brake is to apply pressure to armature 3 by spring 5, the friction plate on brake disc 2 is compressed,Reach the object of braking thereby produce moment of friction, but in reality is used, conventionally will enter braking momentRow is adjusted, to adjust object this patent and set up an adjustment pin 7 in spring 5 bottoms, holes in order to reach, by with yokeSpring force is adjusted in the rotation of the adjusting nut 8 that 4 inner hole threads connect, in the time that adjustment pin 7 is screwed into, and spring forceIncrease, when braking moment increases, back-outs, spring force reduces, and braking moment reduces, but due to brake workAs time have seismism, after long-play, adjusting nut 8 can produce loosening phenomenon, causes brake torqueReduce, for preventing the generation of this type of phenomenon, be provided with the uniform plane that adjustment pin 7 contacts at adjusting nut 8The semi-circular recesses 9 consistent with adjustment pin 7 quantity, while rotating adjusting nut 8, makes the semicircle head of adjustment pin 7Just in time fall in adjusting nut 8 plane semi-circular recesses 9, under the reaction force of spring force, adjusting nut 8Can not produce because of vibrations loosening phenomenon.
More than show and described general principle of the present utility model and principal character and of the present utility model excellentPoint. The technical staff of the industry should understand, and the utility model is not restricted to the described embodiments, above-mentionedThat in embodiment and description, describes just illustrates principle of the present utility model, is not departing from the utility modelUnder the prerequisite of spirit and scope, the utility model also has various changes and modifications, these changes and improvementsAll fall within the scope of claimed the utility model. The claimed scope of the utility model is by appended powerProfit claim and equivalent thereof define.
