Abstract

PURPOSE:To facilitate the ring mounting operation by a construction wherein a cut-out part is formed on the end periphery of each axial rib arranged on the outer periphery of a frame in a superimposed relation with an opening of an outer fan cover on the exhaust side, and a ring is fitted in the cut-out parts. CONSTITUTION:A number of axial ribs 31a are provided on the outer periphery of a tubular frame 31, and an outer fan cover 4 circumscribing outer fans 3 is arranged in a manner that its opening 5 on the exhaust side is superimposed with respect to the end of each rib 31a. Cut-out parts 31b are circumferentially formed on the end periphery of the ribs 31a, and a ring 36 having resiliency in a radial direction is fitted and fixed in the cut-out parts 31b, thereby to reduce a gap at the opening 5. By so doing, it becomes possible to mount a ring without welding operation and hence to make smaller a gap at the opening on the exhaust side of the outer fan cover.

The rotating electrical machine shown in these figures has a large number of axial ribs 31a arranged on the outer periphery of a cylindrical frame 31, and overlaps the end of a support a on the outer periphery of a bladder 7 fixed to the end surface of the frame 31. A notch 31b is provided in the circumferential direction on the outer periphery of the end of the rib 31a. A ring 36 shown in FIG. 5 is fitted into this notch 31b, thereby reducing the gap in the opening 5 so that fingers or the like cannot be inserted therein. The ring 36 is made of spring material,
It is fixed to the notch 31b by a radial spring action.

きるという効果が得られる。As described above, according to the present invention, in an external fan-shaped rotating electrical machine, a notch is provided in the circumferential direction on the outer periphery of the end of the axial rib on the outer periphery of the frame that overlaps with the exhaust side opening of the outer fan cover. A ring that exerts a spring action in the radial direction is fitted and fixed in the opening to prevent fingers from entering through the gap in the opening, which has the effect of simplifying the installation work of the ring.
