摘要	The pressure distributions function is obtained not considering the seal rings' deformation, based on the Reynolds equation under the slid boundary conditions. Changing with the revolving speeds and pressure of fluid in the spiral groove, the corners and deformations of the sealing surface distributions are solved, and the approximate analytic of the corresponding gas film thickness is obtained. Meanwhile, the theoretical leakage not considering forced deformation is obtained by using the Generalized Reynolds Equation. The Maple software is applied to solve the leakages with the forced deformation in the seal ring. The leakages are calculated out and compared with the theoretical values under different pressures. The result shows that with an increasing of pressure, the leakage is increased alone the radial from the outside to inside. In the same condition, the leakage considering forced deformation is closer to the experimental values, compared with theoretical values. Thus it affects the sealing performance.
