- FIG. 6 is a schematic cross-sectional view showing a known elevator hoisting machine.
- the interior of the brake drum 1 that rotates around a main shaft (not shown) under the thrust mainly includes a lining 2, a brake coil 3, an armature 4, a coil fixing part 5, an arm 6,
- the brake part consisting of compression spring 7 and scissors 12 is stored.
- the coil fixing portion 5 is fixed to a central portion in the brake drum 1. Then, members such as lining 2, brake coil 3, armature 4, arm 6, compression spring 7, scissors 12 and the like are provided on both sides of the coil fixing portion 5, respectively. Then, on each side of the coil fixing portion 5, the brake coil 3 is fastened by bolts 10 with a predetermined amount of scissors 12 to be described later interposed.

- armature 4 is fastened to the arm 6 on a side facing the coil fixing portion 5 by a bolt 8 so as to face the brake coil 3.
- armature 4 is an electromagnetic force generated by energizing brake coil 3 described above. The force causes the brake coil 3 to be attracted.
- a lining 2 is supported on a side of the arm 6 facing the brake drum 1. Specifically, the lining 2 is provided with a receiving portion (show) 2 a having a through hole for fastening the bolt 1 1, and the arm 6 is provided with a screw portion to correspond to the through hole of the receiving portion 2 a. Fix the lining 2 to the arm 6 by tightening the bolt 1 1 to the female thread.

- each of the ports 8, 10 and 11 for fastening members to each other is provided at four places in the plane of each member.
- the lining 2 moves toward and away from the brake drum 1 in conjunction with the movement of the armature 4 by the electromagnetic force of the brake coil 3. That is, when the coil portion 3a of the brake coil 3 is energized, the armature 4 is attracted to the brake coil 3 by the electromagnetic force generated there, and the lining 2 is separated from the brake drum 1 in conjunction with this. . On the other hand, when the coil section 3a is de-energized, the armature 4 is released from the brake coil 3 as the electromagnetic force disappears, and the lining 2 is braked by the spring force of the compression spring 7. It comes into contact with the drum 1 at a predetermined pressure. Thus, the rotation of the brake drum 1 is controlled by the contact and separation of the lining 2.

- One is the adjustment of the gap between the brake drum 1 and the lining 2 when the lining 2 is disengaged from the brake drum 1.
- the gap at the time of disengagement improves the responsiveness (time required for abutment) of the lining 2 to abut on the brake drum 1, reduces the collision noise generated at that time, and further reduces the electromagnetic noise generated by the brake coil 3.
- the other is to adjust the degree of parallelism of the facing surface between the armature 4 and the brake coil 3 when the lining 2 is in contact with the brake drum 1.
- the degree of parallelism at the time of this contact is accurately determined so that the electromagnetic force generated by the brake coil 3 efficiently acts on the armature 4 and enhances the attraction between the armature 4 and the brake coil 3. Need to adjust.
- the parallelism between the armature 4 and the brake coil 3 is checked by, for example, a clearance gauge or an optical method. Then, in order to adjust the number of scissors gold 12 installed in each part according to the checked degree of parallelism, remove the port 10 and reassemble the brake coil 3. Thereby, the posture of the brake coil 3 with respect to the coil fixing portion 5 (the height of each support portion) is adjusted, and the parallelism with the armature 4 is also relatively adjusted within a predetermined value.
- the gap between the lining 2 and the brake drum 1 is checked by a clearance gauge or an optical method, for example, while the lining 2 is separated from the brake drum 1 manually or by energizing the brake coil 3. Then, according to the degree of the gap checked, the difference in the number of scissors gold 12 already installed in each part is maintained. To increase or decrease the number while holding, remove Porto 10 and reassemble the brake coil 3. As a result, the height of the brake coil 3 with respect to the coil fixing portion 5 is adjusted while maintaining the previously adjusted parallelism, and accordingly, the gap between the lining 2 and the brake drum 1 is also adjusted to a predetermined value. You.
- the scissors gold 12 is usually formed with a thickness of about 0.1 mm, but it is necessary not only to increase the precision of the parts to reduce the variation between the parts, but also to make the amount proportional to the thickness. The only adjustments that could be made were made.
