るガスタービンのカーボンシール構造。 The rotor is rotatably supported in a fixed bearing holder via a ball bearing that is sprayed with oil jet, and a mating ring that rotates together with the rotor is attached to the rotor between the ball bearing part and the air passage of the compressor. In a carbon seal structure for a gas turbine, in which a carbon spring supported by being biased in the direction of the mating ring via a bellows-like spring is brought into sliding contact with the mating ring, the sliding contact between the mating ring and the carbon ring. An oil groove that opens into the sealing surface is provided on the sealing surface, and an oil supply hole that communicates with the oil groove from the ball bearing side surface of the mating ring is bored in the portion of the mating ring that is closer to the rotor than the oil groove. A carbon seal structure for a gas turbine, further comprising a drain hole extending radially outward from the oil groove in the mating ring.
