Embodiment
Following embodiment is further described the utility model in conjunction with the accompanying drawings:
Referring to accompanying drawing, the utility model is a kind of Normally closed type electromagnetic brake, comprises arrestment mechanism and manual release mechanism.Arrestment mechanism by power-supply controller of electric 1, outward flange 2, pressure spring 4, external splines hub 7, electromagnet 8, armature disc 9, movable friction plate 10, decide friction plate 11, spacer 12 and regulate collar 13 to constitute.Manual release mechanism constitutes by discharging fore-set 3, release base 5 and cam crank 6.Outward flange 2 has two through holes, all lays to discharge fore-set 3, discharges base 5 and is installed on the outward flange 2 circle outerplanars, and cam crank 6 is installed in two and discharges on the base 5.Cam crank 6 comprises semicircular bent axle 6-1, the axle journal 6-2 that is positioned at bent axle 6-1 two ends and the cam 6-3 that is positioned at the middle part, and the cam 6-3 outer end of one of them is provided with outer-hexagonal shape driving head 6-4.Discharge fore-set 3 one ends and be close to the one side of cam 6-3, the other end is close to armature disc 9.
The coaxial axle journal engaging cam bent axle 6 at cam crank 6 two ends can only be made a kind of rotational oscillating motion, when power failure state, outer-hexagonal shape driving head 6-4 with an end on the socket wrench rotating cam bent axle 6, turn an angle, the cam compressing at cam crank 6 two ends discharges fore-set 3, transfer the pressure to armature disc 9, manual release forces pressure spring 4 to shrink, movable friction plate 10, decide friction plate 11, armature disc 9 and regulate the gap to occur between the collar 13 and will unclamp, external splines hub 7 can rotate with transmission shaft 14, thus brake off.
Setting electromagnet 8 hole axles is the x axle, so outward flange 2, external splines hub 7, armature disc 9, movable friction plate 10, decide friction plate 11 and adjusting collar 13 all is and the coaxial work of x axle; Electromagnet 8 is when getting electric or dead electricity, armature disc 9 can only slide on spacer 12, when electromagnetic attraction produces adhesive (brakeless moment) or dead electricity and does not have electromagnetic attraction greater than the total power of spring, then always try hard to recommend moving armature dish 9 compressing movable friction plates 10, form braking moment in movable friction plate 10 and the generation friction of deciding friction plate 11 by spring; Here it is, and common dead electricity is braked connecting and composing substantially of Normally closed type electromagnetic brake.When maintenance adjustment is equipped with the equipment of Normally closed type electromagnetic brake, must finish by hand release at brake off under the power failure state.
Working procedure of the present utility model: power-supply controller of electric 1 energising, electromagnet 8 produces magnetic fields, attracts armature disc (9) to make pressure spring 4 compressions, movable friction plate 10 with decide friction plate 11 and unclamp, movable friction plate 10, external splines hub 7 and transmission shaft 14 can rotate.When needs are braked, electromagnet 8 outages, electromagnet 8 magnetic fields disappear, pressure spring 4 returns, spring force is exerted pressure to armature disc 9, and propagation of pressure is to movable friction plate 10 and decide friction plate 11, produces friction catch moment, makes rotatingshaft 14 ramp to stop.Because this electromagnetic brake is normally closed, when the state of dead electricity, live an end of cam crank 6 with the socket wrench cutting ferrule, turn an angle, there are two cams at cam crank 6 two, discharge fore-set 3 by compressing, propagation of pressure shrinks pressure spring 4 to armature disc 9, movable friction plate 10, decide the gap to occur between friction plate 11, armature disc 9 and the adjusting collar 13 and will unclamps, external splines hub 7 can rotate with transmission shaft 14, thus brake off.Electromagnet 8 is built-in, regulate collar 13 and outward flange 2 externally can guarantee flexibly, convenient, adjust air gap between electromagnet 8 and the armature disc 9 accurately.
