Abstract

PURPOSE:To automatically maintain the length of a gap between a lining and an armature by defining free movement across the axial direction of a boss and providing a stopper with which the attracted armature makes contact, in the boss. CONSTITUTION:When a lining 9 is worn out, the length of the gap A increases. Then, when an electromagnet 8 is excited, an armature 4 moves to the left in the axial direction while elongating the leaf spring 3 by the attractive force of the electromagnet 8. Before the armature 4 makes contact with the lining, the contacting position 4a makes contact with a stopper 13, and a gap corresponding to the worn-out part is formed between the armature 4 and the lining 9. Upon this occasion, the attractive force is transmitted to a slide boss 2b through the contact part 4a of the armature 4 and the stopper 13, and the slide boss 2b moves to the left in the axial direction. When the electromagnet 8 is deenergized, the length of the gap A become equal to that of the gap B.

An object of the present invention is to provide an electromagnetic clutch/brake capable of maintaining a constant gap length at all times, in view of the above-mentioned conventional wave IIK. The configuration of the present invention that achieves this objective is as follows:
The armature is attached via a leaf spring to a boss that is fitted into the shaft and rotates together with the shaft, and further includes a piezoelectric magnet Ktj arranged to attract the armature and a lining facing the armature with a predetermined gap therebetween. When the electromagnet is energized, the armature is attracted against the spring force of the leaf spring and comes into contact with the lining, and when the electromagnet is demagnetized, the armature moves away from the lining due to the spring force. If it is fitted into the shaft so that it can be moved in the axial direction, the resistance force in the axial direction is greater than the spring force of the leaf spring (and the electromagnet A spring ring whose suction force is 64 smaller is attached to the boss Kli, and the axial direction K of this boss is
The free movement of the amateur is restricted, and the boss is equipped with a stopper that allows the amateur to come into contact with it.

m is fixed to the shaft 1 by a key 10, and
The slide boss 2b is spline-fitted to the amateur boss 2aK and is movable in the axial direction. A spring rod 12 is fixed to the slide boss 2bK by a presser member 11. This spring ring 12 is inserted into the armature knife 2aKp and tightened radially inward, thereby restricting free movement of the slide boss 2b in the axial direction.

At this time, when trying to move the spring ring 12 in the axial direction, the resistance force f generated between the spring ring 12 and the armature boss 2a is smaller than the attraction force in the axial direction of the electromagnet 8, and is smaller than the attraction force in the axial direction of the leaf spring 3. It is larger than the spring force fs over . That is, suction force fm>resistance force f>spring force fs...
■There is a relationship. A stopper 13 is provided on the slide boss 2b.
A gap B#i between the stopper 13 and the contact portion 4a of the armature 4 formed to contact the stopper 13 is equal in length to the gap A. Therefore, when the armature 4 contacts the lining 9, the contact portion 4a contacts the stopper 13. Note that the stopper 13 may be configured to come into contact with the outer periphery of the armature 4.

After the armature 4 has moved by the worn length, the armature 4 comes into contact with the lining 9 and the shaft 1 is braked. After that, when the electromagnet 8 is demagnetized and the armature 4 is separated, the length of the gap A becomes the predetermined length again, and the length of the gap A and the gap 7'B becomes different. At this time, when viewed from shaft 1, slide boss 2 b #i

In the above embodiment, the boss 2 is divided into two parts so that the slide boss 2b can move in the axial direction, but the amateur boss 2a and the slide boss 2b are integrated, and the amateur boss 2a is connected to the shirt) 1 with a spline. In combination, the spring ring 12 may directly tighten the shaft 1 to restrict free movement of the boss 2. Further, it goes without saying that the present invention can be applied not only to the electromagnetic brake described above but also to an electromagnetic clutch.

As specifically observed in conjunction with the above embodiments, according to the present invention, the gap length between the lining and the armature can be automatically maintained constant with an inexpensive and simple structure, thereby eliminating the need for complicated disassembly as in the past. No work or maintenance/inspection work is required. Since the gap length is always kept constant in this way, the operating time is always constant and the operation is accurate.
