Below, by plan, the example that electromagnetic braking apparatus provided by the invention is suitable is described.
But, about the part identical or equal with past example, enclose identical symbol and be described.
Shown in Fig. 1 is the interlocking relieving state while rotating (such as, motor) of electromagnetic braking apparatus provided by the invention.The mounting 1a of colyliform electromagnet 1 is provided with field coil 3, the groove 1b that the outside of the field coil 3 of this mounting 1a is arranged is provided with coil spring 2.
The inner side of aforementioned colyliform electromagnet 1 is provided with discoideus wheel armature 4, this colyliform electromagnet 1 is provided with the fixed component 10 of Formation cross-section コ font.
In the inner side of aforementioned fixed component 10, the colyliform side plate 7 be made up of colyliform plate can move in axial direction, and the inner 7a of this colyliform side plate 7 is provided with magnet 11.
Between aforementioned wheel armature 4 and colyliform side plate 7, be configured with colyliform brake disc 8, there is friction material 12 on the two sides of this colyliform brake disc 8, and its wheel hub 9 is provided with running shaft 20, can comfortablely rotate.
Next, when aforementioned component, if be in the state of Fig. 1, owing to switching on power, colyliform electromagnet 1 is in excitatory state, so aforementioned wheel armature 4 will leave colyliform brake disc 8, and is attracted by colyliform electromagnet 1, aforementioned magnet 11 and aforementioned mounting 1a repel because magnetic pole is homopolarity, thus cause leaving aforementioned colyliform brake disc 8.Because wheel armature 4 and colyliform side plate 7 all have left aforementioned colyliform brake disc 8, thus cause being in break relieving state, colyliform brake disc 8 and running shaft 20 all entrys into service.
Next, under the state of Fig. 1, if switch on power, colyliform electromagnet 1 is in non-excitatory state, and as shown in Figure 2, due to the spring force of coil spring 2, wheel armature 4 meeting and colyliform brake disc 8 engage.Meanwhile, mounting 1a and magnet 11 due to magnetic pole different and attract each other, colyliform side plate 7 and aforementioned colyliform brake disc 8 engage, thus cause colyliform brake disc 8 and running shaft 20 to stop the rotation.
But, about the polarity of the magnetic pole of aforesaid magnet 11, in the excitatory situation of Fig. 1, identical with the polarity of mounting 1a, so mutually repel.At Fig. 2 without in excitatory situation, due to aforementioned mounting 1a not forming magnetic pole, but single magnetic material, thus magnet 11 due to the effect of magnetic force and mounting 1a attracting and engage.Aforementioned colyliform brake disc 8 is clamped by wheel armature 4 and colyliform side plate 7, thus is in the state that break opens.
Therefore, when the interlocking relieving state of Fig. 1, except wheel armature 4 moves, irremovable colyliform side plate 7 also can move laterally in the past.Why moving to the outside of this colyliform side plate 7, is because fixed with the blocking device 10a of aforementioned fixed component 10.
Embodiment of the present utility model provides for the purpose of example and description, and is not exhaustively or by the utility model be limited to disclosed form.Many modifications and variations are apparent for the ordinary skill in the art.Selecting and describing embodiment is in order to principle of the present utility model and practical application are better described, and enables those of ordinary skill in the art understand the utility model thus design the various embodiments with various amendment being suitable for special-purpose.
