インバ−タによって回転数が可変にされる大型モ−タ等の回転電機では、回転 数が変化するために回転軸にファンが直結された自冷用の換気機構のみでは必要 な冷却能力が得られないために、強制通風用のブロアを装着する場合があり、こ のような強制通風用のブロアは、多くの場合モ−タ筐体に直接装着される。 上記モ−タの筐体等の回転電機本体に強制冷却用のブロアを装着するには、図 ３に示すような取付構造にされている。 図３において、符号１１はモ−タ等の回転電機であり、回転電機１１における １１ａは回転軸、１１ｂは該回転電機に外部電気回線を接続する端子を設けた端 子函、１１ｃは該回転電機を吊下げる時に使用する吊りボルト、１１ｄは該回転 電機を所定の場所Ｅに設置するフランジであり、１１ｅは回転電機１１の強制通 風の吸入口側の回転電機の筐体である。符号１２は強制冷却用ブロア、符号２は ブロア１２を駆動するモ−タで、前記の回転電機筐体１１ｅはブロア１２を装着 し、その重量を支えるように鋼板製カバ−にブラケットで補強した構造である。 符号１４は、薄鋼板で形成されてブロア１２を保持するファンカバ−であり、 前記回転電機の筐体の補強した端部１１ｅに装着固定され、上部にブロアを保持 するステ−１４ａが内部に設けられている。 ファンカバ−１４の上端と、ブロア１２のブロアカバ−吹出口１３の下端部と は、Ａ部で装着され相互に固定されている。モ−タ２の先端のブロア吹出口内に はブロア１２の図示しない回転羽根が装着され、モ−タ２はブラケット１２ａに より前記ステ−１４ａに固定されている。 上記の構造において、図示しない配線によりブロア１２のモ−タ２に電力を供 給して回転させると、図示しない回転羽根が回転して矢印ａから空気を吸入し、 空気はブロアカバ−の吹出口１３から矢印ｂの経路に沿って、ファンカバ−１４ に送風されて、矢印ｃのように回転電機１１の回転電機筐体の空気流入側の端部 １１ｅから回転電機１１の内部に吹き込まれて回転電機の発熱を冷却し、回転電 機筐体１１ｅの反対側から矢印ｄに示すように排出されて、該回転電機１１の強 制冷却を行っている。 In rotating electric machines such as large motors whose rotation speed is variable by an inverter, the rotation speed changes, so the required cooling capacity can be obtained only with a self-cooling ventilation mechanism in which a fan is directly connected to the rotating shaft. Therefore, a blower for forced ventilation may be attached, and such blower for forced ventilation is often attached directly to the motor housing. In order to install a blower for forced cooling on the rotating electric machine body such as the casing of the motor, the mounting structure is as shown in FIG. In FIG. 3, reference numeral 11 is a rotary electric machine such as a motor. In the rotary electric machine 11, 11a is a rotary shaft, 11b is a terminal box provided with a terminal for connecting an external electric line to the rotary electric machine, and 11c is the rotary machine. A hanging bolt used when suspending the electric machine, 11d is a flange for installing the rotary electric machine at a predetermined place E, and 11e is a casing of the rotary electric machine on the suction port side of the forced flow of the rotary electric machine 11. Reference numeral 12 is a forced cooling blower, and reference numeral 2 is a motor for driving the blower 12. The rotating electric machine casing 11e is equipped with the blower 12, and is reinforced by a bracket on a steel plate cover so as to support its weight. It is a structure. Reference numeral 14 is a fan cover that is formed of a thin steel plate and holds the blower 12. The fan cover is attached and fixed to the reinforced end 11e of the casing of the rotating electrical machine, and a station 14a that holds the blower is provided inside. Has been. The upper end of the fan cover 14 and the lower end of the blow cover outlet 13 of the blower 12 are attached and fixed to each other at the portion A. Rotating blades (not shown) of the blower 12 are mounted in the blower outlet at the tip of the motor 2, and the motor 2 is fixed to the stage 14a by a bracket 12a. In the above structure, when electric power is supplied to the motor 2 of the blower 12 by the wiring (not shown) to rotate it, the rotating blades (not shown) rotate to suck in air from the arrow a, and the air blows out from the blower cover. 13 is blown to the fan cover 14 along the path of the arrow b, and is blown into the rotary electric machine 11 from the end 11e on the air inflow side of the rotary electric machine housing of the rotary electric machine 11 as shown by the arrow c to rotate.

上述の構造の回転電機冷却用ブロアの取付構造では、回転電機の筐体を構成す るカバ−は、ブロアの重量を保持するために補強構造にしたブラケットを設ける 必要があり、ファンカバ−もまたステ−を設けた特殊な構造にする必要がある。 また、ファンカバ−１４の上端部は、Ａ部でブロアカバ−吹出口１３の下端部 で結合され、ファンカバ−１４の吹出し口が回転電機筐体の端部に支持された片 持ち梁構造になっているため、振動に対し不安定で共振を伴いやすい。 上述の構造で運転を実施すると、ファンカバ−、ブロアカバ−は補強部以外は 薄鋼板で形成された片持ち梁構造であるために、回転に伴う振動が共振して騒音 が大になるだけでなく、ブロアの回転羽根が折損し飛散する恐れもあるという問 題があった。本考案は、上記問題を解決して、ブロアの重量を支えるために回転 電機の改造を必要とすることなく、安定静粛な回転を可能にしエンペラ−が破損 する懸念等のない回転電機冷却ブロアの取付構造を提供することを課題とする。 In the structure for mounting the rotating electric machine cooling blower having the above-described structure, the cover forming the casing of the rotating electric machine needs to be provided with a bracket having a reinforcing structure in order to hold the weight of the blower, and the fan cover is also required. It is necessary to have a special structure with a stay. Further, the upper end of the fan cover 14 is joined to the lower end of the blow cover outlet 13 at the portion A, and the outlet of the fan cover 14 is supported by the end of the rotating electric machine casing to form a cantilever structure. Therefore, it is unstable with respect to vibration and easily causes resonance. When the operation is performed with the above structure, the fan cover and the blow cover have a cantilever structure that is made of thin steel plate except for the reinforcement part, so the vibration accompanying the rotation resonates and the noise increases. However, there was a problem that the rotating blades of the blower could be broken and scattered. The present invention solves the above problems and enables stable and quiet rotation without the need to modify the rotating electric machine to support the weight of the blower, and there is no concern that the impeller will be damaged, etc. An object is to provide a mounting structure.

For fixing the attached plate, connecting the blower mounting frame to the blow cover to fix it, and installing it in the blower outlet of the blow cover and the forced ventilation port of the cover of the rotating electric machine for forced ventilation of a specified shape. The problem was solved by connecting a fan cover and a buffer structure.
