Abstract
PURPOSE: To accurately shut off oil by penetrating the rotary shaft with the oil throwing collar facing the conical surface part through the leakage stopping ring with the fan shaped conical surface part at the inner end surface and the labyrynth fin on the inner peripheral surface.
CONSTITUTION: The labyrynth fin 11 is fitted on the inner peripheral surface of the rotary shaft penetrating part 10 of the leakage stopping ring 8 non-contactingly surrounding the outer peripheral of the rotary shaft 9. The oil throwing collar 12 with the conical surface part 13 of which diameter on the penetrating part 10 side is enlarged is formed on the inside of the bearing box of the rotary shaft. The conical surface part 15 is formed on the leakage stopping ring 8 leaving fine clearance between each other. By doins so, fan effect is generated between the conical surface parts 13, 15, and air in the clearance is injected into the bearing box to make the range where the drain and pneumatic balancing hole 16 opens negative pressured, and oil flows out of the conical surface 13 is drawn back to the bearing box.
