ある。In the comb-shaped sliding brush 1 shown in FIG. 1, each brush band material 2 is formed by punching out a band-shaped material with a die, so it is difficult to prevent wear of the die or uneven mold processing technology. , each brush strip material 2 may have a step 9, or it may be tilted diagonally to either the left or right. If such a sliding brush 1 is attached to a spring base material and used as a sliding contact, the contact with the commutator becomes unstable, causing uneven wear, increasing the amount of wear, and shortening the life of the commutator. This causes uneven rotation.

The sliding brush of the present invention is intended to provide a sliding brush in which there is no step in the brush band material and no inclination from side to side.
As shown in FIG. 2.3, a plurality of cut grooves 4 are provided in the longitudinal direction at equal intervals in parallel on one surface of each half of the strip material 30, thereby forming a plurality of brush strip materials 5f. It is something to do.

次に本発明の摺動用刷子の効果を明瞭ならしめる為にそ
の具体的な実施例と従来例について説明する。In each brush strip material 5 formed by providing a plurality of cut grooves 4 in the strip material 3, adjacent ones are connected to each other, so there is no step difference in the vertical direction, and each The brush strip material 5 does not tilt diagonally to the left or right, and is entirely horizontal. Therefore, such brush strip material 5
By attaching the sliding brush 6 to a spring base material and using it as a sliding contact, the contact with the commutator is stable, there is no uneven wear, and the wear is uniform over the entire surface, reducing the amount of wear. The life of the commutator is increased, and the commutator rotates more stably without uneven rotation1.
Next, in order to clarify the effects of the sliding brush of the present invention, specific examples and conventional examples thereof will be described.

One half of the strip material 3 made of o-Cu14-Zn1 alloy is machined with a cutting tool to form two grooves in the longitudinal direction with a v-shaped cross section and a width of 0.05W and a depth of 0105M. 4 in parallel at 0.4 tx intervals, width 0.4
A sliding brush 6 was obtained by forming three brush pieces 5 each having a length of 6 u.

１図に示す如く長さ６ｕ９幅０４關の３本の刷子帯材２
を０．２５ｕ間隔に形成して摺動用刷子１を得た。One half of a strip-shaped material made of the same alloy as in the example with a width of 1.7 m, a length of 10 m, and a thickness of 0.1 mm was punched out using a die to obtain a material with a length of 6 m and a width of 04 cm as shown in Fig. 1. 3 brush strips 2
were formed at intervals of 0.25 μ to obtain a sliding brush 1.
然してこれら実施例及び従来例の摺動用刷子各１００
個について、品質検査した処、従来例の摺動用刷子１に
於いて、刷子帯材２の左右の傾き、段差の生じた不良品
が８個もあったのに対し、実施例の摺動用刷子６に於い
ては、そのような不良品は皆無であった。However, each of the sliding brushes of these embodiments and the conventional example was 100
When we inspected the quality of each piece, we found that in the sliding brush 1 of the conventional example, there were as many as 8 defective products in which the brush strip material 2 was tilted from side to side and had a difference in level, whereas the sliding brush of the example In No. 6, there were no such defective products.
尚、上記実施例の摺動用刷子６は、無垢の材料であるが
、接触面にのみ所要の材料を張り合せた複合材であって
も良いものである。Although the sliding brush 6 in the above embodiment is made of a solid material, it may be made of a composite material in which a desired material is laminated only on the contact surface.
以上詳記した通力本発明の摺動用刷子は、帯状素材の片
半部の一面に、長手方向に複数本の切込溝を平行に等間

が無くなって安定するという優れた効果を奏する。The sliding brush of the present invention described in detail above has a plurality of brush strips formed with a plurality of cut grooves parallel to each other at equal intervals in the longitudinal direction on one surface of one half of the strip material. , each brush strip material is connected and is horizontal with no vertical step and no horizontal inclination. Therefore, when this is attached to a spring base and used as a sliding contact, the contact with the commutator is stable, the wear is uniform over the entire surface, and the amount of wear is reduced, extending the life. , and has the excellent effect of eliminating irregularities in the rotation of the commutator and making it stable.
