Abstract

PURPOSE: To enhance shaft sealing performance through the seal ring in the device wherein sealing of the inside of a machine is performed at a shaft piercing part of a fixing part of a upright rotary machine, a stepped part covering a specified range under the lower surface of the seal ring is provided.
CONSTITUTION: In this sort of the shaft sealing device, a high pressure hermetically sealing liquid 9 is pressed into a chamber 5 from a supply hole 6. Part of said liquid 9 is supplied to a gap g between a rotary shaft 1 and a seal ring 10 through a inlet port 3 of the seal ring 10, and the gap g is maintained uniformly. In such a shaft sealing device, the stepped part 11 is provided at the lower end of the seal ring 10, with its part from the interior circle to the point whose diameter is larger than the diameter of the interior circle of a case 4 being remained. The gap between the case 4 and the ring 10 is expanded from t2Wt3. The supplying pressure Ps of the hermetically sealing liquid 9 sufficiently acts into the gap t3. Thus, the seal ring 10 is smoothly floated, and the shaft sealing performance can be enhanced.
