Description of drawings
Fig. 1 is an assembling assumption diagram of the present utility model.
Fig. 2 is the cutaway view of Fig. 1.
Embodiment
In Fig. 1, provided the concrete structure of brake block 4, this brake block 4 is in the form of annular discs on the whole, the one side promptly matches with friction plate 3 towards a side (being the left side shown in the figure) of friction plate 3, and being furnished with some pieces of fan blades 42 between opposite side, the restriction for the concrete shape and the quantity of fan blade 42 is not illustrated that is to say, though illustrated the shape of fan blade 42 to be streamlined among the figure, do not repelled similar or other forms of fan blade shape.The central authorities of brake block 4 are brake block axle bed 41, also are preset with to be used for brake block 4 is able to realize the keyway 411 that key is solid with the armature spindle of motor and use the screw 412 that is provided with for described adjusting screw dish 5 on brake block axle bed 41.Behind the rotor shaft hatch 413 of the axle head injection brake block axle bed 41 of the armature spindle 8 of motor, fasten with a bolt or latch into to keyway 411 by flat key, and door bolt is gone into keyway 81 on the armature spindle 8 simultaneously, and by this that whole brake block 4 and armature spindle 8 keys are solid, under the rotation of armature spindle 8, drive brake block 4 and rotate together.Armature 2 is also in the form of annular discs, the central authorities of armature 2 one are used for sky and are set to the through hole 21 that brake block axle bed 41 gets on, because the internal diameter of through hole 21 is obviously greater than the external diameter of brake block axle bed 41, therefore, even brake block 4 drives and is under the rotation status at armature spindle 8, armature 2 does not change.Provided three pieces of friction plates 3 that are banana-shaped each other as wherein a kind of execution mode among the figure and under by means of the situation of binding agent, three pieces of friction plates 3 have been adhered to 2 side surfaces towards brake block 4 of armature with bonding mode.In addition, on armature 2, also offer and be used for the pin-and-hole 22 that passed through for the elastic positioning pin 13 that is arranged on yoke 1 one sides, that is to say that armature 2 is also lived and put and can be arranged on the elastic positioning pin 13 of yoke 1 play.The circumferential surface that carries the yoke 1 of coil 11 promptly offers a plurality of spring eyes 14 of blind hole form corresponding to a side surface compartment of terrain of armature 1, in each spring eye 14 spring 15 is set, each spring 15 pastes at an end that exposes spring eye 14 and touches on armature 2, known to figure, after armature 2 was nested with on the elastic positioning pin 13 by the pin-and-hole on it 22, each spring 15 had just constituted contact relation with armature 2.Lead 111 energisings when coil 11, whole winding 11 gets so, coil 11, yoke 1 produce magnetic force together, at this moment armature 2 overcome spring 14 resistance and by adhesive, be that armature 2 is done moving of certain interval toward yoke 1 direction in the axial direction, make between friction plate 3 and the brake block 4 and produce the gap and the zerofriction force square; Otherwise, when coil 11 dead electricity, coil 11, yoke 1 all loss of excitation power, just ejected armature 2 by the restoring force of spring 14 this moment, and the gap between friction plate 3 and the brake block 4 is disappeared and the generation moment of friction.
Described bearing cap 61 and spring leaf 7 lay respectively at the and arranged on left and right sides of bearing 6, revolve and screw 611 to the bearing cap 61 and being arranged in the bearing bore 12 that defaults in yoke 1 by the compound mode shown in the figure and by means of screw 612 each other, like this, when armature spindle 8 passed through bearing 6 and brake block 4 join solid after, because does not change the outer ring of bearing 6, so yoke 1 also just is in static state.Because armature spindle 8 was after passing through yoke 1, armature 2, brake block 4 in regular turn, because of the gap between the gap between armature 2 and the yoke 1 and friction plate 3 and the brake block 4 is determined as requested, otherwise can influence braking effect, therefore, the adjusting in gap each other can be taken on by regulating screw dish 5.Specifically be to regulate with center adjustment screw 51, and marginal screw 52 plays the role of positioning, if the contrary center adjustment screw 51 that revolves, can make the respective clearance between foregoing armature 2 and yoke 1 and friction plate 3 and the brake block 4 become big so, vice versa, and the reasonable change in gap is to make spring leaf 7 produce deformation under the adjusting of center adjustment screw 51 to embody.
In Fig. 2, clearly provided by structural member shown in Figure 1 and assembled relation after finishing each other, in view of the above, the applicant sketches the operation principle of the utility model electromagnetic brake.When equipment for example the textile machine of textile department be in normal operating conditions, motor is to be in the normal operating state so, armature spindle 8 normally rotates, and taking brake block 4 by armature spindle 8 rotates together, by lead 111 coil 11 is got simultaneously, as described above, armature 2 overcomes the spring force of spring 14 and is pull-in on the yoke 1, cement in armature 2 opposite sides and between the friction plate 3 of brake block 4 one sides and brake block 4, have one by predetermined desired gap, promptly friction plate 3 does not touch mutually with brake block 4; And work as equipment downtime or run into special circumstances when needing speed promptly to shut down; so in order to make armature spindle 8 be able to fast braking; at this moment, coil 11 dead electricity are under the Hui Huili of spring 14 effect; make armature 2 move corresponding gap towards brake block 4 directions; the friction plate 3 of this moment just pastes with brake block 4 and touches, and gives corresponding braking force for brake block 4, and since brake block 4 to be dresses solid on armature spindle 8; therefore, the moment of friction by friction plate 3 gives the braking force of brake block 4 and makes armature spindle 8 fast braking.
