| titleOfInvention | A kind of contact floating air film between centers sealing structure and installation method |
| abstract | The present invention relates to a kind of contact floating air film between centers sealing structure, for making to form sealing structure between external bushing and high-pressure shaft, contact floating air film between centers sealing structure includes retainer ring, spring, the first sealed track, sealing ring, the second sealed track, fixed pin, the 3rd sealed track, locking bed and locking member, and retainer ring, spring, the first sealed track, sealing ring, the second sealed track, fixed pin, the 3rd sealed track are placed between external bushing and high-pressure shaft；By being equipped with multiple bleed holes on sealing ring, air-flow forms air film by bleed hole in the sealed track end face contacted with sealing ring.The contact floating gas film sealing structure of the present invention can effectively improve seal performance relative to the sealing of comb tooth, reduce leakage rate, it is of great significance to solving the problems, such as that the next oil temperature of aero-engine, gas turbine application comb tooth band is high and lube use rate is big, the reliability of engine can be improved. |
