本発明は全閉外扇形回転電機の通風装置に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a ventilation device for a totally enclosed external fan-shaped rotating electric machine.
第２図には横形の全閉外扇形回転電機の通風装置の従来
例が示されている。同図に示されているように通風装置
は＃ｌを有する回転子２および回軸１上に設けられ、か

気冷却器５との間を連通する風洞８とから構成されてい
る。なお同図において９は整風板である。FIG. 2 shows a conventional example of a ventilation device for a horizontal totally enclosed external fan-shaped rotating electric machine. As shown in the figure, the ventilation device is provided on the rotor 2 and the rotating shaft 1 having #l, and is provided with an external fan 6 that introduces cooling air from the outside, and surrounding this external fan 6. It is comprised of an external fan cover 7 and a wind tunnel 8 that communicates between the external fan cover 7 and the air cooler 5. In addition, in the figure, 9 is a wind regulating plate.
このように構成された通風装置で、外扇６により導入さ
れた冷却風を空気冷却器５へ導くための風洞８が外扇カ
バー７と一体構造になっていた。In the ventilation device configured in this manner, the wind tunnel 8 for guiding the cooling air introduced by the external fan 6 to the air cooler 5 is integrally constructed with the external fan cover 7.
このため風洞８の部分のみを軸方向に長くする場合に、
風洞８および外扇カバー７の全体を変更しなければなら
なかった。Therefore, when only the wind tunnel 8 portion is lengthened in the axial direction,
The entire wind tunnel 8 and outer fan cover 7 had to be changed.
すなわち軸受ｌＯに例えばすベリ軸受を使用すると、軸

々のものが存在するこのような軸受１０の軸方向長さの
変更に応じて風洞８の長さも変更しなければならないが
、風洞８は外扇カバー７と一体にしであるので、風洞８
および外扇カバー７の全体を変更しなければならない。That is, if a sliding bearing is used as the bearing IO, for example, the axial length of the bearing 10 will be extremely large compared to a rolling bearing. Furthermore, there are various axial lengths of the bearing 10 depending on the dimensions of the rolling bearing and the sliding bearing. However, since the wind tunnel 8 is integrated with the outer fan cover 7, the wind tunnel 8 must be changed.
Also, the entire outer fan cover 7 must be changed.
この風洞８の軸方向長さの変更対策として使用し得る最
大の軸方向長さの軸受１０に合わせて風洞８の長さを決
めておけば、このようにした風洞８および外扇カバー７
は軸方向長さの短かい他の軸受１０についてもそのまま
使用できる。しかしこの場合に回転電機全体の軸方向長
さが必要以上に長くなり、回転電機の据付寸法および輸
送寸法上望ましくない。As a measure to change the axial length of the wind tunnel 8, if the length of the wind tunnel 8 is determined according to the bearing 10 with the maximum axial length that can be used, the wind tunnel 8 and the outer fan cover 7 can be
can also be used as is for other bearings 10 having a shorter axial length. However, in this case, the axial length of the entire rotating electrical machine becomes longer than necessary, which is undesirable in terms of installation and transportation dimensions of the rotating electrical machine.

ることができる。The present invention will be explained below based on the illustrated embodiments. FIG. 1 shows an embodiment of the invention. In this embodiment, the same parts as the conventional one are given the same reference numerals, and the explanation will be omitted.
It is designed to be detachable. By doing so, the wind tunnel 8a is formed to be detachable from the outer fan cover 7 and the air cooler 5, making it possible to easily replace the wind tunnel 8a. You can get the equipment.
すなわち風洞８ａを外扇カバー７および空気冷却器５に

分割して製作するので、風洞８ａ内部および外扇カバー
７内部の整風板９の取り付は溶接作業を容易にすること
ができる。That is, the wind tunnel 8a was fixed to the outer fan cover 7 and the air cooler 5 by tightening bolts 11. By doing so, the wind tunnel 8a can be detachably attached to the outer fan cover 7 and the air cooler 5 with the bolts 11, and the wind tunnel 8a
When changing the axial length of the wind tunnel 8a, only the wind tunnel 8a can be changed, making it easy to replace the wind tunnel 8a. Further, since the wind tunnel 8a and the outer fan cover 7 are manufactured separately, welding work for attaching the air baffle plates 9 inside the wind tunnel 8a and the outer fan cover 7 can be facilitated.

と同様な作用効果を奏することができる。This embodiment differs from the bearings of the previous embodiments in that a flat bearing having a longer axial length than the rolling bearing of the bearing 10 is used. In this case as well, it is only necessary to replace only the wind tunnel and detachably attach the replaced wind tunnel 8a to the outer fan cover 7 and the air cooler 5 with bolts 11, and the same effect as in the above case can be achieved. .
