FACE SEAL OF ROTATING SHAFT

摘要

FIELD: mechanical engineering. SUBSTANCE: to preserve parallel clearance in sealing joint in heat deformations, bandage rings are fitted near friction surfaces of friction couple on movable and fixed sealing rings of aluminium alloy with layer of aluminum oxide. Coefficient of linear expansion of bandage rings from metal materials is less than that of aluminium alloys. EFFECT: higher reliability of face seal. 1 dwg
