Abstract
PURPOSE: To prevent oil from entering into a liquid-cooling rotary electric machine and to also prevent oil from entering into a vacuum pump by employing a ring packing and a labyrinth seal at the seal of a liquid-cooling pressure reducing rotary electric machine.
CONSTITUTION: A sealed casing 3 is provided at the frame 2 for coating a rotor shaft 1 to seal it with the shaft 1 by oil A extracted from the seal ring 4 at the end of the casing 3. A rotary ring 5, ring packing 6 and retaining ring 7 are provided inside the casing 3. A circumferential ring 8 is provided at opposite end to the ring packing 6 with a labyrinth seal 9 formed at both ends of the flange 8A for preventing oil from entering into the rotor. An oil tank 11 is provided at the pressure reducing pipe 10 to prevent oil from entering into a vacuum pump 13.
