整流子２に向かつて押圧されている。 As shown in FIG. 1, first, a coarse sandpaper 1 is placed between the commutator 2 and the brush 3. Then, hold both ends of the sandpaper 1 and move the commutator 2 in the circumferential direction.
The brush 3 is polished so that the surface of the brush 3 facing the circumferential surface of the commutator 2 has the same curvature as the circumferential surface of the commutator 2. Next, repeat the same operation with fine sandpaper 1 to finish. At this time, the brush 3 is held by a brush holder 4 of a rotating electric machine to which the brush is actually attached, and is pressed toward the commutator 2 by a brush holder 5.

３の先端面をサンドペーパ１７に押圧してる。 As shown in FIGS. 2a and 2b, a bearing 8 is fixed to a support plate 7 installed vertically on a floor plate 6. As shown in FIGS. The hand-cranked handle 9 and the drum 10, which are disposed on both sides of the support plate 7, are connected by a rotating shaft 11, so that the handle 9 can be rotated by holding the grip 9a of the handle 9. If possible, the drum 10 can also be rotated integrally. At this time, the diameter of the drum 10 is made to be the same as the diameter of the commutator of the rotating electric machine to which the brush 13 is actually mounted. Further, sandpaper 17 is wound around the entire circumference of the drum 10, and two slits 10a are formed at both ends of the drum 10 in parallel with the rotating shaft 11 in the axial direction.
It is removably inserted inside. That is, the sandpaper 17 can be attached to and detached from the drum 10. Note that the number of the slits 10a is not limited to two, as long as the end of the sandpaper 17 can be inserted therein. Depending on the size of the sandpaper 17, it may be one piece or three or more pieces. The brush holder 12 is the same as the rotating electric machine on which the brush 13 is actually mounted, and a plurality of brush holders (four in the embodiment) are inserted and fixed to the rods 18 fixed to the support plate 7 in parallel to the rotating shaft 11. There is. Each brush holder 12 holds a brush 13, and the brush holder 14 holds the brush 13.
3 is pressed against the sandpaper 17.

６はカバーである。 Note that the brush holder 12 does not necessarily have to be the same (same shape) as long as it can hold the brush 13 so that the brush 13 is held in the same state as the rotating electric machine to which the brush 13 is actually mounted. That is, in general, the brushes of rotating electric machines are often held at an angle with respect to a line perpendicular to the surface of the commutator or slip ring, and in this case, the holding angle is the same as that of the rotating electric machine to which the brushes are actually attached. However, other aspects such as external shape do not necessarily need to be the same. The tray 15 is placed on the floor plate 6 and is adapted to receive the carbon powder. Also, 1 in the figure
6 is a cover.

な摺接が確保されるものとなつている。 When a new brush 13 is attached to the brush holder 12 of the apparatus of this embodiment and the handle 9 is rotated, the sandpaper 17 comes into sliding contact with the tip surfaces of the plurality of brushes 13 in the same way, so that the mating surface of the brush 13 with respect to the commutator is can be formed simultaneously. At this time, since the diameter of the drum 10 is the same as the commutator of the actual rotating electrical machine, good sliding contact is ensured even when the brush 13 is mounted on the rotating electrical machine as is.

There is no need to worry about insulation deterioration of the rotating electric machine due to powder, and the work involved in forming the mating surfaces is dramatically simplified. In particular, since a plurality of brushes can be rubbed together at once by simply rotating the rotating shaft, the efficiency of the rubbing work can be improved from this point as well.
