本発明は回転電機鉄心の通風ダクト構造に係ｐ、特に
ダクト片の凸部とそれを支持するプレート分点溶接によ
り固層した１゛ｊ４造に１夕Ｊする。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a ventilation duct structure of a rotating electric machine iron core, particularly
The convex part of the duct piece and the plate supporting it are solidified by spot welding, and the structure is then fixed for one night.
従来の通風ダクトは、ダクト片とそ、ｒＬを支持するプ
レートを点溶接と凸部のがしめで固着されている。In a conventional ventilation duct, the duct piece and the plate supporting the rL are fixed together by spot welding and tightening of the protrusions.

はグレートに支持されている。Spot welding can be completed in a short time using spot welding equipment, increasing productivity. However, spot welding alone lacks reliability due to welding in an unstable state perpendicular to the plate and the difficulty of non-destructive testing. Therefore, the duct piece is supported by the grate by using the convex portion and the Gray If caulking method in combination.
また、ダクト片凸部とプレートを点溶接しても、かしめ
効果を得られるが、スポット溶接装置の電極を斜め方向
から加圧溶接する必要があり、実用性に欠ける。Also, although a caulking effect can be obtained by spot welding the convex portion of the duct and the plate, it is not practical because the electrode of the spot welding device must be pressure welded from an oblique direction.

。It is necessary to caulk the convex end of the C1 duct piece. Examples of caulking are shown in FIGS. 1 and 2. The duct piece 2 passes through a plate 3 having small holes at positions corresponding to the convex portions 4 and is mechanically fixed by caulking 4a. However, in this method, the caulking 4a protrudes from the plate 3, so if a large number of ventilation ducts are installed in the axial direction as shown in Figures 3 and 4 and the iron core is tightened, the Z and caulking 4a may protrude. Area pressure is received in some areas, and slack occurs in other areas. If the rotating electric machine is operated in this state, vibrations will increase in both the iron core 1 and the ventilation duct, and there is a high possibility that a serious accident will occur, such as damage to the teeth or duct pieces.
本発明の目的は、通風ダクトのダクト片凸部の出張りを
鉄心積厚に影響させない通風ダクトを提供するにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a ventilation duct in which the protrusion of a convex portion of a duct piece of the ventilation duct does not affect the core stack thickness.

も、鉄心は正常の積層面圧を得られる。Duct piece 2rj with a convex portion 4: A small hole is formed in the plate 3a that supports it in correspondence with the convex portion 4, and a small hole is formed in the plate 3a that supports the convex portion 4.
, and further overlap the plate 3b to close the convex part 4,
The convex portion 4 and the plate 3b are spot welded together. By this welding, the convex end 4b and the plate 3b are fixed, and the convex part 3b has a concentric effect when caulked.Also, since the plate 3b has a small protrusion, a large number of ventilation ducts are installed in the axial direction. However, the iron core can obtain normal laminated surface pressure.
また、ダクト片のグレートへの固着はすべて点溶接で作
業可能であり、生産性が向上する。Additionally, all of the duct pieces can be fixed to the grate by spot welding, improving productivity.
本発明によれば、通風ダクトは機械的強度を保持しなが
ら、出張りによる変形がないため、鉄心の積層面圧が均
一化する。According to the present invention, the ventilation duct maintains its mechanical strength and is not deformed due to protrusion, so that the laminated surface pressure of the iron core becomes uniform.
また、ダクト片の固着がすべて点溶接に統一・できるの
で生産性向上効果がある。In addition, all the duct pieces can be fixed by spot welding, which has the effect of improving productivity.
