この場合には、石綿含有の絶縁材料質量体を不要にし、ひいては長い製造プロセ ス時間を無くすことによって、十分に高い耐遠心性を存する環境汚染を招かない コンミテータを大量生産に適した方法で、しかも短いサイクル時間で製造するこ とができ、さらにコンミテータを自動化されたアーマチュア製作ラインにおいて 組み付けることができるという大きな利点が得られる。さらに、たいていは石綿 を含有している公知の汎用の絶縁材料質量体を無くすことによって、一層高い耐 熱性と、一層良好な熱導出とが得られ、各セグメント間の絶縁層の除去も不要と なるという利点が得られる。In this case, asbestos-containing insulating material masses can be dispensed with and thus long manufacturing processes can be avoided. By eliminating the time required for centrifugation, it has sufficiently high centrifugal resistance and does not cause environmental pollution. Commutators can be manufactured in a manner suitable for mass production and with short cycle times. In addition, the commutator can be used in an automated armature production line. A great advantage is that it can be assembled. Furthermore, asbestos is often By eliminating the mass of known general-purpose insulating materials containing Thermal properties and better heat dissipation are obtained, and there is no need to remove the insulation layer between each segment. You get the advantage of being
請求項2以下に記載した手段により、請求項1に記載したコンミテータの冑利な 改良が可能となる。半径方向および/または軸方向でセグメント支持体の長手方 向溝に挿入可能なセグメントのかしめによりて、耐遠心性がさらに高められてい ると特に宥和である。The commutator according to claim 1 can be improved by the means described in claim 2 and subsequent claims. Improvements are possible. the longitudinal direction of the segment support in the radial and/or axial direction Centrifugal resistance is further enhanced by caulking segments that can be inserted into the facing grooves. This is particularly appeasement.
図面 以下に、本発明の実施例を図面につき詳しく説明する。$1図はコンミテータの 縦断面図を示しており、第2図は、第1実施例による長手方向溝に押入されて固 定されたセグメントを備えたセグメント支持体の一部を第1図の矢印方向で見た 図を示しており、第3図は第2実施例による長手方向溝に押入されて固定された セグメントを備えたセグメント支持体の一部を第1図の矢印方向で見た図を示し ている。drawing In the following, embodiments of the invention will be explained in detail with reference to the drawings. The $1 diagram is of the commutator. FIG. 2 shows a longitudinal cross-sectional view, in which the structure is pushed into the longitudinal groove according to the first embodiment and fixed. A portion of the segment support with defined segments viewed in the direction of the arrow in Figure 1. Fig. 3 shows a case where the device is pushed into the longitudinal groove according to the second embodiment and fixed. 1 shows a view of a part of a segment support provided with segments as seen in the direction of the arrow in FIG. ing.
実施例の説明 コンミテータはたとえば鋼またはアルミニウムから成るセグメント支持体1を有 しており、このセグメント支持体は、公知のアーマチュアシャフト(図示しない )に被せ嵌めるための同心的な孔2を備えている。Description of examples The commutator has a segment support 1 made of steel or aluminum, for example. This segment support is connected to a known armature shaft (not shown). ) is provided with a concentric hole 2 for fitting over.
セグメント支持体1はその外周壁3に、周方向で均一に分配された長手方向溝4 を備えている。長手方向溝4を含めて外周壁3には、たとえば紙、ラッカーまた は粉末被覆体として絶縁層5が被着されている。The segment support 1 has longitudinal grooves 4 uniformly distributed in the circumferential direction in its outer circumferential wall 3. It is equipped with The outer circumferential wall 3, including the longitudinal grooves 4, may be coated with paper, lacquer or the like, for example. An insulating layer 5 is applied as a powder coating.
第2図に示したセグメント支持体1の第1実施例では、開いた長手方向溝4の側 壁6が平らに構成されている。セグメント7は一端に、自体公知のアーマチュア コイル(図示しない)の端部を固定するための接続ラグ8を有している。セグメ ント支持体1の長手方向溝4に押入されたセグメント7の固定範囲9は横断面を 楔形に減少させられていて、しかも丸く面取りされた縁部を備えている。したが って、セグメンl−7の固定範囲9の形状はセグメント支持体1の長手方向溝4 の形状に合致している。固定範囲9の長辺10には、各1つの長手方向溝11が 構成されており、この長手方向溝はセグメン)・7のブラシ接触面12から見て アンダカット部を形成している。In the first embodiment of the segment support 1 shown in FIG. The wall 6 is of flat construction. Segment 7 has at one end an armature known per se. It has a connecting lug 8 for fixing the end of the coil (not shown). Segme The fixing area 9 of the segment 7 pushed into the longitudinal groove 4 of the belt support 1 has a cross section. It is reduced to a wedge shape and has rounded beveled edges. However, Therefore, the shape of the fixing area 9 of the segment l-7 is similar to the longitudinal groove 4 of the segment support 1. It matches the shape of. Each long side 10 of the fixing area 9 has one longitudinal groove 11. When viewed from the brush contact surface 12 of segment 7, this longitudinal groove is An undercut portion is formed.
セグメント7はその固定範囲9で、半径方向または軸方向でセグメント支持体1 の長手方向溝4に挿入されて、このセグメント支持体1に機械的に固定される。The segment 7 is radially or axially connected to the segment support 1 in its fixing area 9. is inserted into the longitudinal groove 4 of and mechanically fixed to this segment support 1.
このことは、たとえばかしめによって行なわれる。この場合に少なくとも部分的 に、セグメント支持体1の各長手方向溝4の間に位置する外周壁3の材料がセグ メント7の長手方向溝11に押し込められる。セグメント7は「内方」からもか しめることができる、このためには、たとえばコンミテータが雌型内に緊定され 、セグメント7を備えられたセグメント支持体lが軸方向で押し合わされ、その 結果、セグメント支持体1の押しのけられた材料がセグメント7の長手方向溝l l内にずれ込んで、セグメント7をセグメント支持体1にしっかりと保持する。This is done, for example, by caulking. In this case at least partially In this case, the material of the outer peripheral wall 3 located between each longitudinal groove 4 of the segment support 1 is It is pushed into the longitudinal groove 11 of the ment 7. Segment 7 may also be from the “inward” For this purpose, for example, the commutator is clamped in the female mold. , segment supports l provided with segments 7 are axially pressed together and their As a result, the displaced material of the segment support 1 fills the longitudinal groove l of the segment 7. 1 to securely hold the segment 7 on the segment support 1.
セグメント支持体13の第2実施例では、セグメント支持体13の長手方向溝1 6の開いた端部に位置する側壁15の縁区分14が長手方向溝11に突入するよ うに構成されている。縁範囲14はセグメント7の固定範囲9に設けられた長手 方向溝11に対応して構成されていて、セグメント支持体13の外周!!3から 見て同じくアンダカット部を形成している。In a second embodiment of the segment support 13, the longitudinal groove 1 of the segment support 13 The edge section 14 of the side wall 15 located at the open end of 6 projects into the longitudinal groove 11. It is composed of The edge area 14 is a longitudinal area provided in the fixing area 9 of the segment 7. It is configured to correspond to the directional groove 11, and the outer periphery of the segment support 13! ! From 3 As you can see, it also forms an undercut.
セグメント7はその固定範囲9で、セグメント支持体13の長手方向溝16に軸 方向で挿入され、この場合、a[囲14が、セグメント7に設けられた長手方向 溝11に係合する。これによって、セグメント7は既にセグメント支持体13に 保持されている。セグメント支持体13に設けられた各長手方向溝16の間に位 置する外周壁3の材料をセグメント7の固定範囲9に設けられた長手方向溝11 内に押しのけることによって、セグメント7は(たとえばかしめによって)さら に付加的にセグメント支持体13に固定される。同じく、このセグメント7は第 1実施例の場合のように「内方」からかしめることもできる、これによって、特 に遠心強度が一層高められる。The segment 7 is axially mounted in the longitudinal groove 16 of the segment support 13 in its fixing area 9. direction, in this case a[the enclosure 14 is provided in the segment 7 in the longitudinal direction It engages with the groove 11. As a result, the segment 7 is already attached to the segment support 13. Retained. between each longitudinal groove 16 provided in the segment support 13. The material of the outer peripheral wall 3 to be placed is inserted into the longitudinal groove 11 provided in the fixing area 9 of the segment 7. By pushing inwards, segment 7 is further removed (e.g. by crimping). Additionally, it is fixed to the segment support 13. Similarly, this segment 7 is It is also possible to caulk from the "inside" as in the case of the first embodiment, thereby making it possible to The centrifugal strength is further increased.
コンミテータの組付けは前記両実施例共に簡単な手段で、短いサイクル時間にお いて、自動化されたアーマチュア製作ラインで実施され、したがって特に大量生 産で経済的に行なわれる。The assembly of the commutator in both of the above embodiments is simple and requires short cycle times. is carried out on an automated armature production line and is therefore particularly suitable for high volume production. It is carried out economically in production.
