Abstract

PURPOSE:To raise the cooling effect while sufficiently securing the droplet property and protective property of a large-sized rotary electric machine having a large diameter by forming the concentric ribs formed on a bearing bracket obliquely to be introduced from the outer periphery into the interior of the inner periphery of the machine. CONSTITUTION:In the bearing bracket 1 having a through hole 8 at the center, concentric ribs 3 formed between the outer periphery and the hole 8 are so formed as to be oblique at an angle alpha to be retarded toward the interior 7 of the machine at the hole 8 side. Thus, even if the depths b of the ribs 2 are small, it can sufficiently provide the droplet preventive property and the protective property and reduce the air flow resistance, thereby improving the cooling effect.
