徴とする二重反転軸シール装置。 In a counter-rotating shaft in which the inner shaft and the outer shaft are driven in reverse rotation with each other via a reversing gear, a seal liner that extends further from the outer shaft end is fitted and fixed to the inner shaft, and a ring is attached to the outer shaft end surface. A single seal ring is attached to the seal casing so that the seal ring comes into contact with the outer peripheral surface of the seal liner, and a back-up spring that supports the back surface of the seal ring on the atmosphere side is attached to the seal casing. The back-up spring is installed so that the inner circumferential surface and the outer circumferential surface of the seal liner are arranged with a required gap, and the back-up spring has an oil drain hole that penetrates from the inner circumferential surface toward the side end surface on the side opposite to the seal ring. established,
A counter-rotating shaft sealing device characterized in that an injection means is provided for spraying lubricating oil into the gap between the backup spring and the seal liner.
