PURPOSE: A bearing cooling device is provided to relatively miniaturize a product in which the bearing cooling device is used by forming a cooling water passage is formed inside the device. CONSTITUTION: A bearing cooling device comprises bearing assemblies(63), isolation rings(66), cooling water passages, and a cooling water source. The bearings rotatably support a rotary shaft(59) extended through a housing(53). The insulation rings are located between bearings(65) and the ends of the housing. The cooling water passages are formed between the insulation rings and the ends of the housing. The cooling water source supplies cooling water to the cooling water passage. |
