Abstract

PURPOSE: To avoid the danger of contact of the seal ring with the rotary shaft and to reduce the leakage of fluid on floating the seal ring coaxially to the rotary shaft by changing the step height of the throttle face of the seal ring.
CONSTITUTION: The pressure distribution at the position D is higher than that at the position C in the axial direction because the gap between the slide face 3 and the shaft at C is equal to that at D and ones in the slide face 4 are different from each other. Also the pressure distribution in the circumferential direction is the maximum at D, gradually reduced as it approaches to C, and is the minimum at C. Since the pressure distribution is symmetrical with respect to the line C-D, the direction of combined pressure is opposite to that of the external force Fr such as the gravity. Thus, even though the rotary shaft 1 and the seal ring 2 are coaxial as shown in Figure, the seal ring can be floated by fluid film in the gap.
