重反転軸シール装置。 In a counter-rotating shaft in which an inner shaft and an outer shaft are driven in reverse to each other via a reversing gear, a seal liner extending further from the end of the outer shaft is fitted and fixed to the inner shaft, and an outer shaft is attached to the inner shaft. A single seal ring supported on the shaft side is brought into contact with the seal liner, and a tapered part is formed in the extending part of the seal liner so that the outer diameter gradually decreases as the seal ring moves away from the atmosphere side back surface toward the atmosphere side. A counter-rotating shaft sealing device, characterized in that a spraying means for spraying lubricating oil onto the tapered portion is provided.
