Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail and illustrates:
Figure one is a structural representation of the present invention, the present invention adopts the structure of electromagnet core 3 direct DM armature 8 and left friction plate 11, link by non-self-locking buttress thread form 15 between electromagnet armature 8 and the left friction plate 11, its objective is and make not self-locking of screw thread, when attracting armature 8 with convenient electromagnet, can make electromagnet armature 8 produce the trend of rotation simultaneously, the automatic adjustment in the gap of declutching also will be by the suitable elasticity of electromagnet core 3 with electromagnet armature 8 contact surfaces.When declutching the gap just often, electromagnet armature 8 and electromagnet core 3 Elastic Contact, prevent the rotation of electromagnet armature 8, when declutching excesssive gap, electromagnet armature 8 disengagings contact with electromagnet core 3, when declutching electromagnetic suspension force just make electromagnet armature 8 rotation up to stop the rotation after electromagnet core 3 contact, follow electromagnet armature 8 and compress electromagnet core 3 more vertically and drive left friction plate 11 and declutch, the automatic adjustment in the gap of so just having realized declutching.
The electromagnet core 3 volume inside while is as the installing space of the braking belleville spring 6 of break among the figure one, braking belleville spring 6 is fixing by compression nut 5 compressions, and by break guide rod 4 guiding, break guide rod 4 also is the fixing body of electromagnet armature 8 and left friction plate 11 simultaneously.Such structure has reduced axial dimension greatly, has reduced installing space, so volume is compact especially.Braking butterfly spring 6 is made up of the belleville spring of high rigidity, and the belleville spring specialized designs becomes nonlinear elastic characteristic, see shown in the figure two, and the operation point of braking butterfly spring 6 is chosen at the horizontal segment of figure two elastic curves, by figure two as seen, when brake strip 11 wearing and tearing cause braking butterfly spring 6 distortion when reducing, the elastic force of brake spring reduces hardly, therefore the braking moment of break generation also reduces hardly, so just improve the Security of break greatly, reduced to adjust the workload of safeguarding simultaneously.
When the mounting point of break and brake disc 14 produce errors, the situation that contacts of brake strip 11 and brake disc 14 is with variation, generation for fear of this situation, link by spherical bearing 12 between brake strip 11 and the miscellaneous part among the figure one, spherical bearing 12 is to receive friction plate a certain size preload pressure of screw rod 9 is installed when flat, therefore can at will not swing, when friction plate 11 and brake disc 14 bad connections, braking force is enough to make spherical bearing 12 swings, with the position of automatic adjustment friction plate 11, realize friction plate 11 automatically with bit function.
For preventing under abnormal conditions such as power failure can release brake, the present invention has designed special manual brake release, shown in figure one, break guide rod 4 in the braking belleville spring 6 is simultaneously also as the part of manual brake release, have groove at break guide rod head, so that manually declutch wrench can insertion groove in, the operation of manually declutching.
Electromagnet coil 1 is installed in electromagnet core 3 inside, the electromagnet coil design characteristic is, the normal power supply voltage of the coil just voltage of specified adstante febre designs very lowly, but when beginning the moment of switching on, supply with the voltage of 3~5 times of coil overrates, making electric current in the coil also is just often 3~5 times, make electromagnet core 3 saturated like this, produce enough electromagnetic attraction DM armature 8 and brake strip 11, behind the electromagnetic actuation, voltage is in time recovered normal value, avoid coil to be burnt by regulator, reduce the volume and weight of electromagnet so widely, also significantly reduced the power consumption of electromagnet simultaneously.
The effect of belleville spring 17 of declutching is that whole break is moved to right, thereby makes right friction plate 11 leave brake disc 14, and brake clearance is adjusted nut 16 can adjust the position that break moves to right, thereby adjusts the gap of declutching.
