Abstract

PROBLEM TO BE SOLVED: To secure a space for elongating an iron core by changing the arrangement and shape of a fan and an iron core holding member.SOLUTION: The arrangement and shape of a fan and an iron core holding member are changed to secure a space for elongating an iron core. The iron core holding member to which the fan is attached is designed to function as a fan, and fan effect generated by a rotor bar is also used, thereby allowing cooling wind to circulate in the interior of a main motor. Integrating the fan with the iron core holding member secures the space for elongating the iron core.

Description

本発明は，車両用の台車内に据え付けられている主電動機の回転子の構成に関するものである。   The present invention relates to a configuration of a rotor of a main motor installed in a vehicle carriage.

全閉型の主電動機には，内部に冷却風を循環させるためのファンが回転子に組込まれている。多くの場合は，ファンは回転子に設けられた鉄心押えに取付けられている。（特許文献１）   A fully-enclosed main motor incorporates a fan for circulating cooling air inside the rotor. In many cases, the fan is attached to a core retainer provided on the rotor. (Patent Document 1)

全閉型の主電動機の場合は，主電動機の運転による発熱をできるだけ低く抑える必要があるため，鉄心長を長くする必要が生じやすく，ファンが占有する部分を小さくする等で，スペースを確保する必要がある。   In the case of a fully-enclosed main motor, heat generation due to operation of the main motor needs to be kept as low as possible, so it is often necessary to lengthen the iron core, and space is secured by reducing the portion occupied by the fan. There is a need.

解決しようとする課題は、内部に循環させる冷却風を多く必要としない場合は，大きなファンを必要としないため，ファンの小型化を実現し，鉄心を長くする際のスペースを確保することである。   The problem to be solved is to reduce the size of the fan and secure a space for lengthening the iron core because a large fan is not required if a large amount of cooling air circulating inside is not required. .

請求項１の発明によれば、車両用の台車内に据え付けられている全閉型主電動機の回転子に複数個の風穴５有する構成において、回転子バー４と短絡環３の内周面に接するように外周面を有する鉄心押え７を配設し、鉄心押え７の外周面と回転子１対向面で囲まれた空間に、風穴５が配置され、放射状の羽根８が形成されることを特徴とする。   According to the first aspect of the present invention, in the configuration in which a plurality of air holes 5 are provided in the rotor of a fully-enclosed main motor installed in a vehicle carriage, the rotor bar 4 and the short-circuit ring 3 are provided on the inner peripheral surface. An iron core retainer 7 having an outer peripheral surface is disposed so as to be in contact, and the air hole 5 is disposed in a space surrounded by the outer peripheral surface of the iron core retainer 7 and the surface facing the rotor 1, and the radial blades 8 are formed. Features.

すなわち、鉄心押え７の外周部が各回転子バー４の内径側の内周面と、短絡環３の回転子１側の側面と、短絡環３の内径面とに微小隙間で沿うように形成され、鉄心押え７が保持する回転子１側と反対側の鉄心押え７の側面は、短絡環３部分では、短絡環３の軸方向の厚み長さ以内のところに形成され、軸１２側では短絡環３の軸方向の厚み長さ以上のところに段差を有するように形成され、羽根８は、鉄心押え７の回転子１側の側面から回転子バー４の軸方向の長さより小さい軸方向の長さを有し、羽根８は、鉄心押え７と一体で形成され、隣り合う放射状の羽根８の内径側に、回転子１の回転子風穴５位置を合わせることを特徴とする。   That is, the outer periphery of the core retainer 7 is formed so as to be along the inner peripheral surface on the inner diameter side of each rotor bar 4, the side surface on the rotor 1 side of the short-circuit ring 3, and the inner diameter surface of the short-circuit ring 3 with a minute gap. The side surface of the core retainer 7 opposite to the rotor 1 side held by the core retainer 7 is formed within the axial thickness of the short-circuit ring 3 in the short-circuit ring 3 portion, and on the shaft 12 side. The vane 8 is formed so as to have a step at a thickness greater than or equal to the axial length of the short-circuit ring 3, and the blade 8 is axially smaller than the axial length of the rotor bar 4 from the side surface on the rotor 1 side of the core retainer 7. The blade 8 is formed integrally with the iron core retainer 7, and the rotor air hole 5 position of the rotor 1 is aligned with the inner diameter side of the adjacent radial blade 8.

さらに、ファンと鉄心押えの形状と配置を変更し，鉄心を長くする際のスペースを確保する。ファンを取付ける側の鉄心押えにファンの機能を持たせ，回転子バーによるファン効果を併用することで，主電動機の内部の冷却風の循環を実現する。   In addition, the shape and arrangement of the fan and the iron core retainer will be changed to ensure space for making the iron core longer. By providing the core retainer on the side where the fan is mounted with the function of a fan and using the fan effect of the rotor bar, the cooling air inside the main motor can be circulated.

本発明の回転子の構成は，ファンを取付ける側の鉄心押えにファンの機能を持たせてあり，回転子バーによるファン効果を併用することで，主電動機の内部の冷却風の循環を可能としている。ファンが鉄心押えと一体となることで，鉄心を長くする際のスペースが確保できるようになっている。   The structure of the rotor of the present invention is such that the iron core presser on the side where the fan is attached has the function of a fan, and the fan effect by the rotor bar can be used together to enable circulation of cooling air inside the main motor. Yes. By integrating the fan with the iron core retainer, it is possible to secure a space for lengthening the iron core.
