The electromagnetic force generated by the magnetic coil resists the pushing force of the spring', causing the armature to move toward the magnetic vehicle side to release the braking of the rotating shaft. The type of electromagnetic 敔 direct access is used for the above-mentioned four-dimensional operation without excitation. Second, the excitation-actuated electromagnetic brake includes: a flat plate 煞iJ 疋 is on the above-mentioned rotating shaft and perpendicular to the rotating shaft, and Rotating in conjunction with the rotating shaft; the yoke is disposed on one side of the disc and has an excitation coil and a spring built therein; and the remaining portion is movable between the disc and the magnetic tube in the axial direction of the rotating shaft. And the rotation of the rotating shaft is not rotatable; and the cup-shaped outer casing is configured to cover the disc and the armature, and is disposed between the outer casing and the armature when the disc is braked. The disc-shaped armature plate facing the disc tray may be fixed on the inner side of the outer casing and clamped between the armature plate and the armature. The thickness of the sheet forming the outer casing may also be 5 mm or less. Further, the outer plate 312XP/invention specification (supplement)/96·08/96109671 7 200809114 may have a plate thickness of 3 inches or less. It can also be sintered to make an outer casing. The outer peripheral surface can also be formed by stamping or by the fixing means of the outer casing pair (four). The outer casing is inserted from the outer casing side in the axial direction for fixing the yoke to form a defect σ on the outer casing, the armature and the disc. (4) The head end face of the fixing bolt can also be located on the side of the yoke than the arm frame (the effect of the invention). According to the above configuration, the outer casing is fitted to the outer circumference of the magnetic vehicle and the wrong pair can be excluded from the axial pair of the outer space of the disk, so the deliciousness: '=the outer diameter of the disk is expanded to the same extent as the magnetic vehicle. Therefore, the friction is increased by half, so that the braking torque can be translated without increasing the outer diameter of the electromagnetic brake, or the size and weight can be reduced while maintaining the braking torque. For example, an 80 mm electromagnetic brake with a mean radius of friction is 1.25 times the radius of a conventional construction. The increase ratio is not the same as the outer diameter of the electromagnetic brake, but in the electromagnetic brake with smaller outer diameter, the friction radius can be about 1.5 times the conventional radius. Further, since the outer casing can be formed into a cup shape and the structure is strongly produced in a flat plate-shaped armature plate, the thickness of the outer casing can be made thin. Therefore, in the case where the disc is held between the outer casing and the armature, the axial dimension and the outer diameter can be reduced. Furthermore, since the above configuration has the function of the electric raft, the number of components can be reduced. " 312Χρ/发明发明(补件)/96-08/96109671 8 200809114 f On the one hand, 'the armature plate in contact with the disc plate can be set as a separate part from the outer casing' to reduce the requirements on the outer casing. The strength makes it possible to thin the outer shell. Further, according to the above configuration, the outer diameter can be further reduced. Moreover, according to the above configuration, it is easier to manufacture the outer casing in terms of processing. Further, according to the above configuration, the outer diameter can be prevented from increasing by the fixing means. According to the above configuration, after being mounted as an electromagnetic brake, the fixing screw can be passed through the 艮p so that the fixing bolt can be mounted on the inner side of the outer diameter of the disk to prevent the fixing bolt from colliding with the disk. Therefore, it is possible to prevent the fixing bolt from restricting the outer diameter of the disc.

"", the center portion of the magnetic vehicle 23 is formed with an opening 23a penetrating through the brake rotating shaft i, and an annular groove 23b is formed on the surface facing the armature 24. In the groove 23b, the groove 23b is provided. The excitation coil 23c is configured to adsorb the armature 24, and as shown in FIG. 3, the yoke 23 and the armature 24 face each other, and the accommodation hole 23d' is formed on the outer side of the groove 23b. In the hole 23d, "the coil spring 23e which pushes the armature 24 to the side of the disc 22 is placed. Further, three receiving holes 23d are formed at intervals of 120 degrees on the circumference. The electrode 24 is formed at the center portion. There is a disk-shaped member having an opening 24a (see Fig. 4) that is passed through the brake rotating shaft 1. The outer casing is formed by combining the circular plate portion 25a# perpendicular to the rotating shaft with the cylindrical portion parallel to the rotating shaft. In order to prevent the armature 24 from rotating, the armature 24 is formed with a hole 24c for preventing rotation (see FIG. 2) at three locations in the circumferential direction, and is inserted into the hole 24c in the yoke 23. In order to prevent the pinion from rotating, the armature 24 is held in the following manner, and the pin τ is used as a guide to move in the axial direction and rotate. The direction cannot be rotated. 312ΧΡ/Invention Manual (Repair)/96-08/96109671 10 200809114 Forming the plate of the outer casing 25 (4) _ Manufactured. In the circular plate part, the center part of the punching process P 25a is formed with a large hub The opening of the aperture 25c. The squadron and the squadron of the scorpion 25 are spliced to the outer circumference of the yoke 23 and fixed to the yoke 23 by means of a cymbal. In this example, such as HI! U Λ solid 1 and As shown in Fig. 2, the fixing means is formed by the outer end of the circle w 25b toward the rotating shaft port and the #3 H + upward pressing of the three pins 26 = the head end of the pin 26 is repeatedly protruded from the cylindrical portion: On the magnetic vehicle 23, the armature 24, the disc sensitive and the outer casing 25' are mounted, and in this state, a pin hole is formed from the outer side of the outer casing 25, and the pin 26 is pressed into the pin hole.

The non-, =^, and excitation-actuated electromagnetic brakes 20, in the excitation coil 23c = ::, due to the pushing force of the helical magazine 23e, will = the disk 22, thereby 'as shown in Figures 2 and 3 From the outside...; the pivot 24 holds the disc tray 22, applies braking to the brake rotating shaft i, and, when the exciting coil 23c is energized, the electromagnetic force generated by the exciting coil 2 is as shown in FIG. As shown, the armature 24 is moved toward the yoke 23 side against the urging force of the coil spring to release the brake. According to the configuration of the first embodiment, when the outer casing 25 is fitted to the outer circumference of the magnetic vehicle 23, the head end surface of the fixing bolt 27 is located on the yoke side more than the friction surface of the armature 24, because & There is no such thing as the conventional disk-making disk 22 is smaller than the magnetic mineral & 23, and the outer diameter of the disk disk can be expanded to the same extent as the yoke 23. Therefore, the braking torque can be increased without increasing the outer diameter, or the size and weight can be reduced while maintaining the braking torque. Moreover, since the outer casing 25 can be formed into a cup shape, the structural 312XP/invention specification (supplement)/96·〇8/96! 〇967 i 12 200809114 is stronger than the flat armature plate, The size and outer diameter of the axial direction of the electromagnetic brake can be reduced by making the thickness of the outer casing 25 thinner than that of the conventional armature plate. Further, since the pin 26 constituting the fixing means does not protrude beyond the outer peripheral surface of the outer casing 25, it is possible to prevent the electromagnetic brake from being increased by the fixing means. Further, in the first embodiment, the fixing bolts 27 are inserted from the non-excited actuating type electromagnetic brake side and fixed to the fixing portion 2, and the notches 25d, 22b are formed in the outer casing 25, the disc tray 22, and the armature 24. And 24b, but when the bolt is fixed from the side of the fixing portion 2, the gap is not required. [Embodiment 2] Next, a non-excited actuation type electromagnetic brake 20A according to a second embodiment of the present invention will be described based on Fig. 5 . Fig. 5 is a cross-sectional view showing the non-excitation type electromagnetic brake 20A of the second embodiment in a plane parallel to the brake rotating shaft. The same components as those in Embodiment 1 are denoted by the same reference numerals and the description thereof will be omitted. In the second embodiment, a disc-shaped armature plate 28 opposed to the disc 22 is fixed inside the outer casing 25. In the configuration of the second embodiment, when the exciting coil 23c is not energized, the armature 24 is pushed to the disc tray 22 by the urging force of the coil spring 23e, whereby the electric yoke 28 and the armature 24 are sandwiched. The holding disc 22' applies a brake to the brake rotating shaft 1. As in the second embodiment, the armature plate 28 is disposed inside the outer casing 25, whereby the armature plate 28 can bear the role of the friction surface, so that the load on the outer casing 25 becomes smaller with respect to the embodiment, so that the outer casing can be formed. The thickness of the 25 sheet is thinner than that of the 312XW invention specification (supplement)/96.961〇9671 13 200809114. For example, the thickness of the plate can be made y to be less than 3 mm. Therefore, compared with the first embodiment, the outer casing 25 can be easily fabricated by stamping the w. The second embodiment is based on the modification of the fixing means for the outer casing 25 on the magnetic disk 23 based on the ® 6 to ® 9. An example is given. Fig. 6 to Fig. 9 are cross-sectional views showing a yoke and a casing of a modification 丨 to 4 of the fixing means, respectively. . (Modification 1) Fig. 6 shows a modification 1. As shown in the figure, a hole 23g for fixing is formed in the yoke 23, and an opening 25e' is formed in a portion corresponding to the casing 25. The outer casing 23 is fixed to the yoke 23 by the equal hole 23g and the opening 25e, and the countersunk screw 29 is locked and coupled. (Modification 2) FIG. 7 shows a modification 2, and as shown in the figure, a hole 23h for fixing is formed in the yoke 23, and a cylindrical portion formed by punching a portion corresponding to the outer casing 25 is formed. The 25f is inserted into the hole 23h to be riveted, whereby the outer casing 25 is fixed to the magnetic vehicle 23. (Modification 3) Fig. 8 shows a modification 3 in which a plug 30 is inserted into a hole which is riveted in the same manner as in the modification 2 of Fig. 7 to be reinforced. (Variation 4) FIG. 9 shows a modification 4 in which a conical surface 23i is formed on the magnet 23 by using a countersunk head 31 having a head larger than that of the countersunk screw 29 used in the first modification. The peripheral portion of the outer casing 25 is recessed toward the inner side along the conical surface 23i 312 χ / / invention specification (supplement) / 96-08 / 96109671 14 200809114, whereby the head of the screw 31 does not protrude from the shell 25: . 23上' makes the head in the variants. The outer peripheral surface of the outer casing 25 protrudes, and therefore, the fixing means does not increase from the outer diameter of the magnetic brake. The re-fixing means may be used to make the gap gauge (not shown) of the thickness shown above by means of soldering or the like. The gap is set as follows: 2' in the magnetic consumption 2 3 Clamping gap with electric mop 24: setting: 2, etc. 5 =) secondly, the opening portion of the shaft portion of the braked rotating shaft i or the radial direction formed in the outer casing 25 is mounted (^, Extracting the gap gauge 'by this' appropriately sets the gap between the armature and the yoke of the non-magnetic type electromagnetic brake of the present application. ... Excitation, in the case of the second embodiment or the modification Between the armature and the yoke, the gap between the armature and the yoke is set.
