This win The metal fittings can be used to press the brush surface against the commutator of the motor or In addition to serving as a holding plate to ensure smooth and proper contact with the slip ring, it also serves as a support plate during use. A function that prevents damage or abnormal wear to the brush body due to vibrations, shocks, etc. It becomes the member responsible for the
【０００３】 当金具をブラシ本体の頭部に固定する手段としては、従来から銅管による加締 めと接着剤による接合が代表的な方法とされている。しかしながら、銅管加締め による場合には、加工、組立などに工数と熟練を要するうえ、ブラシ本体に加締 め用の孔や座金用の座ぐり等を穿設しなければならないため材料強度が低下する 問題点がある。一方、接着接合による場合には、接着、熱処理等の工程が必要と なり、また用いる接着剤の耐熱度以上の温度条件での使用が制約される等の難点 がある。このほか、ネジやハンダによる固定手段も用いられているが、加工、工 数などの負担は前記の銅管加締、接着剤接合などと大差はない。0003 As a means of fixing the metal fitting to the head of the brush body, caulking with a copper pipe has traditionally been used. Typical methods include bonding with metal and adhesive. However, copper pipe caulking In this case, processing and assembly require man-hours and skill, and the brush body is The strength of the material decreases because it is necessary to drill holes for screw holes and counterbores for washers. There is a problem. On the other hand, when using adhesive bonding, processes such as adhesion and heat treatment are required. There are also disadvantages such as restrictions on use at temperatures higher than the heat resistance of the adhesive used. There is. In addition, fixing methods such as screws and solder are also used, but There is no big difference in terms of numbers and other costs from the aforementioned copper pipe tightening, adhesive bonding, etc.
【０００４】 また、スプリング等の押圧力が強く、使用中の振動および衝撃が大きな用途（ 例えば電動車）に対しては、ブラシ本体の損傷や異常摩耗を軽減する目的で当金 具の上部に防振材を取り付ける構造に設計される。この種の防振材取付けブラシ を製造するには、例えば硬質ゴムなどで構成した防振材を接着剤または加硫処理 によって当金具に固着したのち、銅管加締もしくは接着剤接合等の固定手段を介 してブラシ本体に固定するプロセスが従来の代表的な方法とされている。しかし ながら、これらの方法は加工の工程が多く、工期および工数の面で経済的負担が 大きくなるうえ、銅管加締法を採る場合には加工孔等を設ける関係で材質強度が 減退する欠点がある。0004 In addition, applications where the pressing force of springs, etc. is strong and vibrations and shocks during use are large ( For example, for electric vehicles), we provide a special amount to reduce damage and abnormal wear on the brush body. The structure is designed so that vibration isolating material is attached to the top of the tool. This type of vibration isolation material installation brush In order to manufacture vibration damping materials such as hard rubber, adhesives or vulcanization are After fixing it to the metal fitting, use fixing means such as copper pipe caulking or adhesive bonding. The process of fixing the brush to the brush body is considered to be a typical conventional method. but However, these methods require many processing steps and are an economic burden in terms of construction period and man-hours. Not only is it larger, but when using the copper pipe caulking method, the strength of the material is reduced due to the preparation of holes etc. There are drawbacks to its decline.
